Resumo

Studies incorporating the nesting behavior and ecology of parasite disease in the European turtle dove during breeding periods are rare. This research examined nest features and nesting materials in Turtle doves to characterize nest dimensions, build, and incorporate vegetation, mainly aromatic and medicinal plants. In parallel, we estimated the ectoparasite load on chicks to verify an eventual relation between odorant plants and pathogen loads. The study was carried in apple orchards at Okhaja Ait Ayach, Midelt province Morocco, during 2015 and 2016. The obtained results demonstrate that the Turtle dove constructs a medium nest, compared to its body size, using several plant species, including medicinal and aromatic species known for their toxicity against pathogens. The inhibition capacity of nesting materials is reflected in parasite loads since only 8% of chicks were infested with Columbicola columbae and Dermanyssus gallinae. Repellent materials in nests are a successful behavioral strategy for this declining game to protect nestlings against pathogens.(AU)

During the breeding season, many avian species face spatial and seasonal variation in the availability of food resources required to rear chicks. Reduction of food abundance is often identified as the most important factor determining population trends and breeding success in bird species, such as the vulnerable European Turtle dove Streptopelia turtur. During the breeding periods, the increase of food requirements in chicks should increase foraging effort to maintain the amount of food required for optimal chick growth. To investigate the feeding effort of Turtle doves during the breeding season, we monitored foraging and drinking rates, in different wild habitats and farmlands, from March to September 2016-2017 in Midelt, Morocco. Similarly, breeding chronology, including nesting, laying, and chicks' fledging, were monitored in the same habitats to evaluate the correlation between breeding efforts and foraging rates. We found that Turtle doves feed actively from the arrival to departure dates. Foraging activities were intense during breeding phases, mainly laying and chicks' growth periods. Equally, Doves feed intensively during the end of the breeding season before migration departures. Besides, Doves feed actively during the morning and evening to avoid the hottest periods as a strategy to save metabolic water.(AU)
