Study of human knowledge and attitude toward urban birds in Faisalabad city, Pakistan

Abstract Birds are very valuable indicators of species richness and endemic patterns in a specified ecosystem, which eventually help the scientist to measure the environmental degradation. The aim of present study was to know human knowledge and attitude toward urban birds in Faisalabad city, Pakistan. The study conducted in four consecutive months: November 2019 to February 2020. Population of birds was noted from eight residential towns of Faisalabad city, data were collected through questionnaire. Faisalabad has a reasonably large population of birds and present data show that, there is a significant difference between favorite bird of residential areas and institutions. The pigeon received the most likeness in bird population among residential area residents, while the myna received the least. The most popular bird in Faisalabad institutions was the sparrow, while the least popular bird was the common myna. Bird adaptation percentage of residential areas and institutional areas of Faisalabad was the highest for parrot and sparrow respectively. People in residential areas and institutions, on the other hand, adapted least to common myna. It is concluded that people of the study area like birds and offered food and high population of birds are present in study area.

Bell-trap effectiveness to capture Crypturellus obsoletusand Crypturellus tataupa(Aves: Tinamidae) in southern Brazil

Specific techniques for the efficient capture of forest tinamous in a short sampling time are yet poorly described in the literature. Here, we report the efficiency of the bell-trap in the capture of Brown Tinamou (Crypturellus obsoletus) and Tataupa Tinamou (Crypturellus tataupa), in southern Brazil. We used three bell-traps adapted with casting nets. In 80 hours of sampling effort, four adult individuals of C. obsoletus were captured, in a forest area in the Pampa Biome. This study area is located in the municipality of São Sepé, state of Rio Grande do Sul, Brazil. Subsequently, in 16 hours of sampling effort in a forest area of the Atlantic Forest domain, one individual of C. obsoletus and one of C. tataupa were captured. This other study area is located in the municipality of Passo do Sobrado, RS. The bell-trap method has already been reported as efficient in capturing Yellow-legged Tinamous (Crypturellus noctivagus), in southern Brazil. However, since forest tinamous are cryptical birds, field adaptations are often necessary to achieve success in sampling activities. The use of this method proved efficient in the capture of forest tinamous, generating an important tool for the collection of bioecological data of this group of birds, which still represents a lack of studies.(AU)

Studies of Brazilian birds along altitudinal gradients: a critical review

Brazil is home to many mountain ranges which harbor diverse avifauna. However, studies on the altitudinal distribution of Brazilian birds are still few and many have never been published, hampering both the dissemination of basic information and conservation actions. Here we present a critical review of ornithological studies undertaken in Brazilian mountain ranges, and propose a classification of geographic scope, altitudinal gradient, and methodology. Since 1922, 184 ornithological studies included altitude in some way in Brazil, encompassing a variety of research topics and species. About a quarter of these studies were never published in peer-reviewed journals, and 39% do not provide basic data on elevation nor link the bird species with sampling plots, thus limiting their applicability. The majority of studies are concentrated (83%) in southern and southeastern Brazil, especially in the Serra do Mar range, and so most data are associated with the Atlantic Forest. Gaps remain in other regions, such as Amazonia (Pantepui region). Most studies either did not sample the entire elevation gradient, were not standardized, lacked explicit hypothesis, or did not account for a seasonal sampling embracing the four seasons of the year, so interpretation of the observed patterns remains difficult. With this compilation, we organize the available information and point to future altitudinal research on birds, in addition to highlighting the importance of preserving habitats along altitudinal gradients in the mountainous regions in Brazil.(AU)

Diversity of avian species, their ecosystems and climate conditions in two zones of High Atlas (central Morocco) for ecotouristic purposes

The analysis of avian diversity and their natural ecosystems at a regional scale is the first step to understanding and classifying a specific region's ecological importance and, therefore, adopting sustainable economic activities and implementing suitable conservation measures. This study investigated the avian richness and natural ecosystems in Eastern and central High Atlas between 2015 and 2021. Transects and point-count methods were used to identify and estimate populations of birds and to delimit the nature of ecosystems. A total of 175 bird species among resident-breeders, migrantbreeders, migrant-winterers, and accidental-visitors were documented. These birds belong to 19 orders and are grouped into 51 families. Among recorded birds, 20 species were categorized as species of ectouristic interest due to their roles in birdwatching, hunting, racing sports, and trade activities. These species were observed in natural and human-made ecosystems, with the majority in wetlands. The abundance of a wide range of ecosystems and various bioclimatic stages is suggested to be behind the avian richness of these mountainous areas. Finally, these natural landscapes and their avian richness could be used for ecotouristic purposes. Visitors could profit from the view of landscapes and observation of the most iconic and rare animal species, which is suggested to increase the income for local populations and ensure the sustainable use of natural resources.

Apparent calcium retention and digestibility coefficients of limestone with different particle sizes in laying hens

Apparent calcium (Ca) retention and digestibility coefficients are affected by limestone particle size in the diet of laying hens. This study aimed to determine the apparent retention and digestibility coefficients of Ca in limestone of different particle sizes in laying hens. The study comprised 288 Lohmann Brown laying hens (50 weeks of age; 1,964 ± 98 g) distributed in a completely randomized experimental design with a 3 × 2 factorial arrangement [three Ca concentrations (10, 20, and 30 g kg-1) × two limestone particle sizes (480 and 1,978 µm)] with eight repetitions per treatment and six birds per experimental unit. The experiment included five days for adaptation and five days for total excreta collection. All birds were slaughtered at the end of the ten days to collect the ileal contents. The total or ileal Ca content was plotted against the Ca of diets concentration using linear regression analysis. The regression line slope represented the apparent retention (CaR) and digestibility coefficients of Ca (CaD) in limestone. There was interaction between Ca concentration in the diet and limestone granulometry on CaD (p = 0.001) and CaR (p < 0.001). The CaD and CaR of fine- and coarse-grained limestone increased linearly with increasing Ca concentrations in the diet. The apparent digestibility coefficients estimated for laying hens fed with fine-grained and coarse-grained limestone were 0.72 and 0.35, respectively. The apparent retention coefficients estimated for laying hens fed fine-grained and coarse-grained limestone were 0.96 and 0.47, respectively.

Avian biodiversity assessment studies in a Neotropical wetland - the combination of sampling methods makes the difference

In studies of avian diversity, many different methods have been applied. Since methodological approaches may affect research results, the choice of a given methodology must be consistent with the scientific objectives. The aim of this study was to investigate how different methodologies with their intrinsic limitations help detect and monitor birds to evaluate how they complement each other in the survey of species. Three different assessment methods, mist nets, point counts, and autonomous acoustic recordings were used to serve this purpose in a study of different Pantanal habitats, such as savannas and forests. The point counts detected more species (126 species) than the two other methods autonomous acoustic recordings (113 species) and mist nets (79 species). We observed significant differences in the number of species detected by mist nets and the other two methods. Each survey method identified exclusive species. When comparing habitats, all three methods showed significant differences in bird species composition. Savannas were richer in bird species than forests, and replacement was the main driver responsible for the differences in beta diversity between the habitats. The three methodologies, when applied together, proved to be complementary in avian species detection.

Particularidades da reprodução de aves silvestres / Particularities of wild birds reproduction

O conhecimento sobre a reprodução de aves silvestres está em constante evolução com o avanço de novas pesquisas. O número gigantesco de espécies de aves e a dificuldade de acesso aos seus gametas são aspectos complicadores para o estabelecimento de técnicas de reprodução assistida. Aspectos muitos básicos como métodos de coleta de sêmen e as características seminais da grande maioria das aves silvestres são desconhecidos. Essas informações são fundamentais para entender a biologia reprodutiva e planejar programas de multiplicação com o uso de inseminação artificial. Por isso o levantamento das principais particularidades da reprodução de aves silvestres norteará ações para o aprofundamento de pesquisas já realizadas e estímulo ao desenvolvimento de novas metodologias de coleta de sêmen e avaliação seminal em aves silvestres até o momento não estudadas.(AU)

The knowledge about the reproduction of wild birds is constantly evolving with the advancement of new research. The large number of bird species and the difficult access to their gametes are complicating aspects for the establishment of assisted reproduction techniques. Very basic aspects such as semen collection methods and the seminal characteristics of the vast majority of wild birds are unknown. This information is fundamental for understanding reproductive biology and planning multiplication programs using artificial insemination. Therefore, the survey of the main particularities of the reproduction of wild birds will guide actions for the deepening of research already carried out and encourage the development of new methodologies for semen collection and seminal evaluation in wild birds that have not been studied so far.(AU)

Prevalence and diversity of ectoparasites in Wild Rock Pigeon (Columba livia) in Punjab region, Pakistan

Abstract The current study was carried out to estimate the prevalence and diversity of ectoparasites in rock pigeons in different regions of Punjab, Pakistan. A total of 120 birds were captured from March 2017 to February 2019. The ectoparasites were collected by standard procedures and preserved in 70% ethanol containing one drop of glycerin. Data related to age, health status, sex, type of area, sampling location and season were collected using a standardized form. Ectoparasites were identified based on morphological characteristics by using identification keys. Ninety-six (80%) birds were infested with ectoparasites. A total of seven families and thirteen species of different ectoparasites were observed. Mainly, seven species of lice, two species of flies, one species of tick and three species of mites were recovered from infested birds. The female pigeons were more often infested (89.02%) than male pigeons (60.52%). The prevalence was found higher during summer (100%) as compared to other seasons. The infestation rate was higher in Industrial area (97.50%) as compared to other regions. The highest prevalence of ectoparasites (100%) was recorded from Sargodha district. There was significant (P 0.05) variation among number of ectoparasites on wing, chest, tail and neck within age groups, seasons and ecological zones. The occurrence of parasites in relation to area, age, health status, sex and season were significant. The infestation rate of parasites in rock pigeon is high in different districts of Punjab. It is recommended that these wild birds infested with multiple species of ectoparasites could be the potential source of infestations in domesticated birds if they come in contact with them. The contact of domesticated birds should be prevented from wild birds to minimize the chance of cross species transmission of ectoparasites.

Resumo O presente estudo foi realizado para estimar a prevalência e diversidade de ectoparasitas em pombos-das-rochas em diferentes regiões de Punjab, Paquistão. Um total de 120 aves foram capturadas de março de 2017 a fevereiro de 2019. Os ectoparasitas foram coletados por procedimentos padrão e preservados em etanol 70% contendo uma gota de glicerina. Os dados relativos à idade, estado de saúde, sexo, tipo de área, local de amostragem e época do ano foram coletados em formulário padronizado. Os ectoparasitas foram identificados com base nas características morfológicas por meio de chaves de identificação. Noventa e seis (80%) aves estavam infestadas com ectoparasitas. Um total de sete famílias e treze espécies de diferentes ectoparasitas foram observados. Principalmente, sete espécies de piolhos, duas espécies de moscas, uma espécie de carrapato e três espécies de ácaros foram recuperadas de aves infestadas. Os pombos fêmeas foram infestados mais frequentemente (89,02%) do que os pombos machos (60,52%). A prevalência encontrada foi maior no verão (100%) em comparação com as outras estações. A taxa de infestação foi maior na área Industrial (97,50%) em relação às demais regiões. A maior prevalência de ectoparasitas (100%) foi registrada no distrito de Sargodha. Houve variação significativa (P 0,05) entre o número de ectoparasitas na asa, tórax, cauda e pescoço dentro das faixas etárias, estações do ano e zonas ecológicas. A ocorrência de parasitas em relação à área, idade, estado de saúde, sexo e estação do ano foi significativa. A taxa de infestação de parasitas em pombo-correio é alta em diferentes distritos de Punjab. Recomenda-se que essas aves selvagens infestadas com várias espécies de ectoparasitas possam ser a fonte potencial de infestações em aves domesticadas se entrarem em contato com elas. O contato de aves domesticadas deve ser evitado com aves selvagens para minimizar a chance de transmissão cruzada de ectoparasitas.

Ecomorphology and functional diversity of generalist and specialist bird assemblages in Amazonian whitesand ecosystem habitat patches / Ecomorfologia e diversidade funcional de assembleias de aves generalistas e especialistas em manchas de habitat de ecossistema de areia branca na Amazônia

Birds that inhabit white-sand ecosystems (WSE) in the Amazon are adapted to habitats distributed as isolated patches. These environments occur in sandy soils that are extremely poor in nutrients, have low floristic diversity and support bird assemblages restricted to WSE. We investigated whether bird species specialized in WSE have morphological or ecological traits that distinguish them from generalist birds that share the same habitat but are not restricted to WSE. We collected morphological and ecological data from 22 specialist and 102 generalist bird species from WSE and described their ecomorphological diversity using multivariate analyses and measures of functional diversity. Understory insectivorous species that move alone or in pairs, were the group with the most species among specialist birds from WSE. In contrast, canopy frugivorous species that form mono- or heterospecific groups were more frequent among generalist species. Specialist and generalist birds overlapped extensively in ecomorphological space, with specialists occupying a narrower space compared to generalists. Functional diversity, however, was not different between specialist and generalist species when controlling for the number of species within the communities. Further studies comparing the ecomorphological diversity of bird assemblages of other environments in the Amazon may highlight the ecological pressures leading to the functional diversity of specialist species in WSE observed in this study.(AU)

As aves que habitam os ecossistemas de areia branca (EAB) na Amazônia estão adaptadas a habitats distribuídos em manchas isoladas. Esses ambientes ocorrem em solos arenosos extremamente pobres em nutrientes, possuem baixa diversidade florística e suportam assembleias de aves restritas a EAB. Investigamos se espécies de aves especializadas em EAB possuem características morfológicas ou ecológicas que as distinguem de aves generalistas que compartilham o mesmo habitat, mas não estão restritas a EAB. Coletamos dados morfológicos e ecológicos de 22 espécies de aves especialistas e 102 generalistas de EAB, e descrevemos sua diversidade ecomorfológica usando análises multivariadas e medidas de diversidade funcional. Espécies insetívoras do sub-bosque que se movem solitárias ou em pares foram o grupo com maior número de espécies dentro das aves especialistas da EAB. Em contraste, espécies frugívoras de dossel que formam grupos mono ou heteroespecíficos foram mais frequentes entre as espécies generalistas. Aves especialistas e generalistas sobrepuseram-se extensivamente no espaço ecomorfológico, com especialistas ocupando um espaço mais estreito em comparação com generalistas. A diversidade funcional, no entanto, não foi diferente entre espécies especialistas e generalistas ao controlar o número de espécies dentro das comunidades. Estudos futuros comparando a diversidade ecomorfológica de assembleias de aves de outros ambientes na Amazônia podem destacar as pressões ecológicas que levam à diversidade funcional de espécies especialistas em EAB observadas neste estudo.(AU)

New records of chewing lice (Insecta: Phthiraptera) parasites of Brazilian Anhimidae, Threskiornithidae, and Aramidae (Aves)

We present records of chewing lice collected from bird skins of the families Anhimidae, Threskiornithidae, and Aramidae deposited at the Museum of Zoology of University of São Paulo (MZUSP). Twenty-one chewing lice species from the suborders Amblycera and Ischnocera were identified, seven of which are new records for Brazil. These species belong to the genera Ardeicola (1), Colpocephalum (3), Ibidoecus (1), and Plegadiphilus (2). Furthermore, ten species were recorded from new localities in Brazil, and Colpocephalum cayennensisPrice & Emerson, 1967 is for the first time recorded with precise locality in the country. Lastly, the bird host subspecies Phimosus infuscatus nudifrons (Spix, 1825) (Threskiornithidae) was for the first time found to harbor lice species.

Seasonal altitudinal movements of birds in Brazil: a review

Birds' seasonal altitudinal movements in Brazil are poorly understood. The main source of information and has fostered interest since the 1980s. However, most of the available information is anecdotal, sources are repeatedly cited, and the information provided is quite superficial and speculative. Through bibliographic searches, we found 107 studies, 83 (77%) of which we consider valid, and only 63 (59%) were peer-reviewed. Most studies were carried out in southern and southeastern Brazil. Only 11 studies explicitly addressed seasonal altitudinal movements. Surprisingly, none of the studies simultaneously comprised a full year of study, standardized sampling methods, and encompassed the entire altitudinal range through which the birds might have moved. As a consequence, the quality of the data is questionable, and the expression "altitudinal migration" is unlikely to be accurate and has never been unequivocally demonstrated for birds in Brazil. Mention of "altitudinal migration" was found for 68 bird species, but these must be more clearly defined and appropriately tested.(AU)

Studies of Brazilian birds along altitudinal gradients: a critical review

Brazil is home to many mountain ranges which harbor diverse avifauna. However, studies on the altitudinal distribution of Brazilian birds are still few and many have never been published, hampering both the dissemination of basic information and conservation actions. Here we present a critical review of ornithological studies undertaken in Brazilian mountain ranges, and propose a classification of geographic scope, altitudinal gradient, and methodology. Since 1922, 184 ornithological studies included altitude in some way in Brazil, encompassing a variety of research topics and species. About a quarter of these studies were never published in peer-reviewed journals, and 39% do not provide basic data on elevation nor link the bird species with sampling plots, thus limiting their applicability. The majority of studies are concentrated (83%) in southern and southeastern Brazil, especially in the Serra do Mar range, and so most data are associated with the Atlantic Forest. Gaps remain in other regions, such as Amazonia (Pantepui region). Most studies either did not sample the entire elevation gradient, were not standardized, lacked explicit hypothesis, or did not account for a seasonal sampling embracing the four seasons of the year, so interpretation of the observed patterns remains difficult. With this compilation, we organize the available information and point to future altitudinal research on birds, in addition to highlighting the importance of preserving habitats along altitudinal gradients in the mountainous regions in Brazil.(AU)

Studies on parasitic prevalence in pet birds from Punjab, Pakistan

Abstract During this one year study, blood and fecal samples of doves (Zenaida asiatica), ducks (Anas platyrhynchos), pigeons (Columba livia), partridges (Alectoris chukar), turkeys (Meleagris gallopavo) and goose (Chen caerulescens) were collected to assess the parasitic prevalence in these birds. The birds were kept at Avian Conservation and Research Center, Department of Wildlife and Ecology, University of Veterinary and Animal Sciences, Lahore. All these avian species were kept in separate cages and their entire body was inspected on regularly basis to record external parasites. For internal parasites, 100 blood and 100 fecal samples for each species were analyzed. During present study, two species of ectoparasites i.e. fowl ticks (Args persicus) and mite (Dermanyssus gallinae) while 17 species of endoparasites; three from blood and 14 from fecal samples were identified. Prevalence of blood parasites was Plasmodium juxtanucleare 29.3%, Aegyptinella pullorum 15% and Leucoctoyzoon simond 13%. Parasitic species recorded from fecal samples included 6 species of nematodes viz. Syngamus trachea with parasitic prevalence of 50%, Capillaria anatis 40%, Capillaria annulata 37.5%, Heterakis gallinarum 28.3%, Ascardia galli 24% and Allodpa suctoria 2%. Similarly, two species of trematodes viz. Prosthogonimus ovatus having parasitic prevalence of 12.1% and Prosthogonimus macrorchis 9.1% were also recorded from fecal samples of the birds. Single cestode species Raillietina echinobothrida having parasitic prevalence of 27% and 3 protozoan species i.e. Eimeria maxima having prevalence 20.1%, Histomonas meleagridis 8% and Giardia lamblia 5.3% were recorded. In our recommendation, proper medication and sanitation of the birds houses and cages is recommended to avoid parasites.

Em nossa recomendação, são indicados medicação adequada e saneamento das casas e gaiolas dos pássaros para evitar parasitas.

Wild birds trade in Dera Ismael Khan and Bannu divisions of Khyber PakhtunKhwa (KPK) Province, Pakistan

Abstract Wildlife trade is a profitable economic activity. Birds are among the most heavily traded animals worldwide, with numerous species threatened by pet trade. The present case study was stretched for period of one year to find out the status of wild birds trade in Bannu and Dera Ismael Khan Divisions. The study was aimed to find out the types of species, commercial prices of bird, trade routes, overall income generated from birds trade and the status of dealers whether licensed or not. Bimonthly visits were conducted to interview 52 bird dealers/pet shops owners/venders (23 in Dera Ismael Khan and 29 in Bannu). A sum of 16 conceivable sites were visited during the study period. Out of these, 8 sites were located in Dera Ismael Khan and 8 sites in Bannu Division. The highest priced species was Demoiselle crane (Grus virgo) and the lowest priced species was house sparrow (Passer domesticus). Total number of species traded in both regions were 8 and 14 while the income generated by bird trade was amounting to PkR 1,322,200 and 7,128,950 in Dera Ismael Khan and Bannu respectively. Majority of the birds were trapped locally with the exception of few from adjacent areas. Commercial activity led by illegal bird traders was found 75% and 100% species in Dera Ismael Khan and Bannu respectively. There was no significant difference between prices of birds, number of species sold and income generated by bird trade in two divisions.

Resumo O comércio de animais selvagens é uma atividade econômica lucrativa. Os pássaros estão entre os animais mais comercializados em todo o mundo, com inúmeras espécies ameaçadas pelo comércio de animais de estimação. O presente estudo de caso foi estendido por um período de um ano para descobrir a situação do comércio de aves selvagens nas Divisões Bannu e Dera Ismael Khan. O estudo teve como objetivo descobrir os tipos de espécies, os preços comerciais das aves, as rotas comerciais, a receita geral gerada pelo comércio de aves e o status dos negociantes, licenciados ou não. Visitas bimestrais foram realizadas para entrevistar 52 comerciantes de pássaros / proprietários / vendedores de pet shops (23 em Dera Ismael Khan e 29 em Bannu). Uma soma de 16 locais concebíveis foram visitados durante o período de estudo. Destes, 8 sites estavam localizados em Dera Ismael Khan e 8 sites na Divisão Bannu. A espécie com preço mais alto foi o guindaste Demoiselle (Grus virgo) e a espécie com preço mais baixo foi o pardal (Passer domesticus). O número total de espécies comercializadas em ambas as regiões foi de 8 e 14, enquanto a receita gerada pelo comércio de aves foi de PkR 1.322.200 e 7.128.950 em Dera Ismael Khan e Bannu, respectivamente. A maioria das aves foi capturada localmente, com exceção de algumas das áreas adjacentes. A atividade comercial liderada por comerciantes ilegais de aves foi encontrada com 75% e 100% de espécies em Dera Ismael Khan e Bannu, respectivamente. Não houve diferença significativa entre os preços das aves, o número de espécies vendidas e a receita gerada pelo comércio de aves nas duas divisões.

Study of human knowledge and attitude toward urban birds in Faisalabad city, Pakistan / Estudo do conhecimento humano e da atitude em relação às aves urbanas na cidade de Faisalabad, Paquistão

Abstract Birds are very valuable indicators of species richness and endemic patterns in a specified ecosystem, which eventually help the scientist to measure the environmental degradation. The aim of present study was to know human knowledge and attitude toward urban birds in Faisalabad city, Pakistan. The study conducted in four consecutive months: November 2019 to February 2020. Population of birds was noted from eight residential towns of Faisalabad city, data were collected through questionnaire. Faisalabad has a reasonably large population of birds and present data show that, there is a significant difference between favorite bird of residential areas and institutions. The pigeon received the most likeness in bird population among residential area residents, while the myna received the least. The most popular bird in Faisalabad institutions was the sparrow, while the least popular bird was the common myna. Bird adaptation percentage of residential areas and institutional areas of Faisalabad was the highest for parrot and sparrow respectively. People in residential areas and institutions, on the other hand, adapted least to common myna. It is concluded that people of the study area like birds and offered food and high population of birds are present in study area.

Resumo Os pássaros são indicadores muito valiosos da riqueza de espécies e padrões endêmicos em um determinado ecossistema, o que acaba ajudando o cientista a medir a degradação ambiental. O objetivo do presente estudo foi conhecer o conhecimento humano e a atitude em relação às aves urbanas na cidade de Faisalabad, Paquistão.

Wild birds trade in Dera Ismael Khan and Bannu divisions of Khyber PakhtunKhwa (KPK) Province, Pakistan / Comércio de aves selvagens nas divisões Dera Ismail Khan e Bannu da província de Khyber Pakhtunkhwa (KPK), Paquistão

Abstract Wildlife trade is a profitable economic activity. Birds are among the most heavily traded animals worldwide, with numerous species threatened by pet trade. The present case study was stretched for period of one year to find out the status of wild birds' trade in Bannu and Dera Ismael Khan Divisions. The study was aimed to find out the types of species, commercial prices of bird, trade routes, overall income generated from birds' trade and the status of dealers whether licensed or not. Bimonthly visits were conducted to interview 52 bird dealers/pet shops owners/venders (23 in Dera Ismael Khan and 29 in Bannu). A sum of 16 conceivable sites were visited during the study period. Out of these, 8 sites were located in Dera Ismael Khan and 8 sites in Bannu Division. The highest priced species was Demoiselle crane (Grus virgo) and the lowest priced species was house sparrow (Passer domesticus). Total number of species traded in both regions were 8 and 14 while the income generated by bird trade was amounting to PkR 1,322,200 and 7,128,950 in Dera Ismael Khan and Bannu respectively. Majority of the birds were trapped locally with the exception of few from adjacent areas. Commercial activity led by illegal bird traders was found 75% and 100% species in Dera Ismael Khan and Bannu respectively. There was no significant difference between prices of birds, number of species sold and income generated by bird trade in two divisions.

Resumo O comércio de animais selvagens é uma atividade econômica lucrativa. Os pássaros estão entre os animais mais comercializados em todo o mundo, com inúmeras espécies ameaçadas pelo comércio de animais de estimação. O presente estudo de caso foi estendido por um período de um ano para descobrir a situação do comércio de aves selvagens nas Divisões Bannu e Dera Ismael Khan. O estudo teve como objetivo descobrir os tipos de espécies, os preços comerciais das aves, as rotas comerciais, a receita geral gerada pelo comércio de aves e o status dos negociantes, licenciados ou não. Visitas bimestrais foram realizadas para entrevistar 52 comerciantes de pássaros / proprietários / vendedores de pet shops (23 em Dera Ismael Khan e 29 em Bannu). Uma soma de 16 locais concebíveis foram visitados durante o período de estudo. Destes, 8 sites estavam localizados em Dera Ismael Khan e 8 sites na Divisão Bannu. A espécie com preço mais alto foi o guindaste Demoiselle (Grus virgo) e a espécie com preço mais baixo foi o pardal (Passer domesticus). O número total de espécies comercializadas em ambas as regiões foi de 8 e 14, enquanto a receita gerada pelo comércio de aves foi de PkR 1.322.200 e 7.128.950 em Dera Ismael Khan e Bannu, respectivamente. A maioria das aves foi capturada localmente, com exceção de algumas das áreas adjacentes. A atividade comercial liderada por comerciantes ilegais de aves foi encontrada com 75% e 100% de espécies em Dera Ismael Khan e Bannu, respectivamente. Não houve diferença significativa entre os preços das aves, o número de espécies vendidas e a receita gerada pelo comércio de aves nas duas divisões.

Assessment of Cholinesterase inhibition activity of birds inhabiting pesticide exposed croplands and protected area in hot semi-arid region of Pakistan

Abstract Acetylcholinesterase (AChE) activity levels can be used as an indicator for AChE inhibition due to pesticide poisoning in bird species. We assessed the comparative brain cholinesterase (AChE) activity level of five bird species inhabiting pesticide exposed croplands and Protected Area i.e. Deva Vatala National Park (DVNP), Bhimber by using a spectrophotometric method. AChE activity levels ranged from 56.3 to 85.9 µmol/min/g of brain tissue of birds representing DVNP. However, AChE activity levels ranged from 27.6 to 79.9 µmol/min/g of brain tissue of birds representing croplands. AChE activity levels observed in Jungle babbler, Common babbler, and Red-vented bulbul showed significant differences (P 0.05) at two sites. However, White wagtail and Black drongo demonstrated non-significant differences (P > 0.05). Maximum inhibition was recorded in Jungle babbler (53%) followed by Common babbler (35%), Red-vented bulbul (18%), White wagtail (15%), and Black drongo (7%). The brain cholinesterase inhibition levels under-protected ecosystems (DVNP, Bhimber) and agricultural landscape suggest insecticidal contamination and its impact on avifauna diversity. The study also emphasizes on the importance of pesticide-free zones to protect the biodiversity of birds.

Resumo Os níveis de atividade da acetilcolinesterase (AChE) podem ser usados como um indicador para a inibição da AChE devido ao envenenamento por pesticidas em espécies de aves. Avaliamos o nível de atividade comparativa da colinesterase cerebral (AChE) de cinco espécies de aves que habitam áreas cultivadas expostas a pesticidas e Área Protegida, ou seja, Deva Vatala National Park (DVNP), Bhimber, usando um método espectrofotométrico. Os níveis de atividade da AChE variaram de 56,3 a 85,9 µmol / min / g de tecido cerebral de aves representando DVNP. No entanto, os níveis de atividade da AChE variaram de 27,6 a 79,9 µmol / min / g de tecido cerebral de aves representando áreas de cultivo. Os níveis de atividade de AChE observados no tagarela da selva, tagarela comum e bulbul vermelho exalado mostraram diferenças significativas (P 0,05) em dois locais. No entanto, alvéola branca e drongo preto demonstraram diferenças não significativas (P > 0,05). A inibição máxima foi registrada no tagarela da selva (53%), seguido pelo tagarela comum (35%), bulbul vermelho (18%), alvéola branca (15%) e drongo preto (7%). Os níveis de inibição da colinesterase cerebral nos ecossistemas subprotegidos (DVNP, Bhimber) e na paisagem agrícola sugerem contaminação por inseticida e seu impacto na diversidade da avifauna. O estudo também enfatiza a importância das zonas livres de pesticidas para proteger a biodiversidade das aves.

Avifauna de uma área de floresta atlântica no sul do Brasil sob influência de atividade minerária / Birds from an Atlantic Forest remnant in southern Brazil under the influence of quarrying

O principal objetivo do nosso trabalho foi o levantamento da composição (riqueza e abundância) da avifauna em um remanescente florestal de Mata Atlântica em Santa Catarina, suscetível à ampliação e intervenção de uma pedreira para subsidiar futuras análises de impactos ambientais dessa atividade. Registramos 142 espécies de aves, distribuídas em 16 ordens e 42 famílias. A partir dos resultados, concluímos que a riqueza total de espécies não deve ser afetada pela ampliação da área de lavra sob o remanescente. No entanto, constatamos que a abundância das aves foi menor nas proximidades da borda da mata, especialmente das aves endêmicas, ameaçadas e especialistas de sub-bosque. Dessa maneira, esperamos que a abundância nas áreas florestais adjacentes seja maior por um período, após o deslocamento das espécies, e diminua ao longo do tempo, à medida em que as relações ecológicas intraespecíficas e interespecíficas aumentem pela competição por recursos e território no habitat. Alertamos que se o tamanho do remanescente não for suficiente para populações viáveis, nossa hipótese é que haja um lapso temporal até que as espécies mais sensíveis desapareçam do local. O tamanho e qualidade do fragmento remanescente deve ser fundamental para minimizar os impactos da atividade e garantir a persistência das populações de aves sensíveis e especializadas na região. Por esse motivo, se a expansão da mina ocorrer, advertimos para que os remanescentes florestais do entorno sejam preservados para garantir a migração e persistência de aves sensíveis, principalmente insetívoras de sub-bosque relatadas em nosso estudo. Nesse contexto, apontamos cinco medidas prioritárias que devem ser implementadas pelo empreendedor, caso o órgão licenciador delibere em favor da ampliação/manutenção da atividade minerária: 1) aquisição dos remanescentes do entorno para transformá-los em RPPN, 2) reposição florestal equivalente à área desmatada, 3) contribuir com as ações do Plano de Ação Nacional para conservação das aves da Mata Atlântica por meio de medida compensatória, 4) diminuição da área de mina para exploração e 5) monitoramento de aves durante a instalação e operação do empreendimento.

The main objective of our work was to survey the composition (richness and abundance) of birds in a forest remnant of the Atlantic Forest in Santa Catarina, southern Brazil, susceptible to the expansion of quarrying activities to support future analyzes of the environmental impacts. We recorded 142 bird species, distributed in 16 orders and 42 families. We propose that species richness shall not be affected by the expansion of quarrying into the remnant; however, we recorded that bird abundance was significantly lower near the forest edge than in the interior, especially of endemic, threatened and understory specialist species. Thus, if quarrying operation expands, we expect the bird abundance in adjacent forest remnants will be higher after species displacement, then will decrease over time as intra- and interspecific ecological relationships increase through competition for resources and territory. The size and quality of the remaining fragments are fundamental to reduce impacts of the activity and ensure the persistence of populations of sensitive and specialized birds in the region. For this reason, if the quarrying expands into the remnant area, then we propose that the surrounding forests be protected to ensure the migration and persistence of sensitive birds, mainly understory insectivores. In this context, we propose the following five actions to be implemented by the entrepreneur: 1) acquisition of surround remnants to be converted into Private Protected Areas, 2) reforestation equivalent to deforested area, 3) contribute to the National Action Plan for the Conservation of Atlantic Forest Birds through compensatory measures, 4) reduction of quarrying area, and 5) bird monitoring program.
