RESUMO
Zoos and aquariums are well placed to connect visitors with the issues facing biodiversity globally and many deliver interventions that seek to influence visitors' beliefs and behaviors with respect to conservation. However, despite primary studies evaluating the effect of such interventions, the overall effect of engaging with zoos and the factors that influence this effect remain unclear. We conducted a systematic review to investigate the effect of zoo-led interventions on knowledge, beliefs (attitudes, intentions, self-efficacy, and social norms), and behavior among zoo visitors. These outcomes were identified using the Theory of Planned Behavior as a theoretical lens. We identified and described the nature of zoo-led interventions in 56 studies and used the behavior change technique (BCT) taxonomy to identify 6 specific BCTs used in interventions to date. Multilevel meta-analyses revealed a small to medium positive effect of engaging with zoo-led interventions on outcomes (d+ = 0.40, 95% confidence interval = 0.28-0.51). Specifically, visitors were more knowledgeable about conservation issues, held more favorable attitudes toward conservation, and reported being more likely to act for the benefit of biodiversity. No evidence of publication bias was present. Effect sizes were, however, heterogeneous and subgroup analyses revealed that the nature of the intervention or type of outcome did not explain this variance. Larger effects were, however, found in studies conducted at a single institution relative to research at multiple institutions and studies that used within-participant designs relative to between-participant designs. Taken together, these findings demonstrate how behavior change frameworks can be used to describe zoo-led interventions and supports the assertion that zoos and aquariums can promote changes in beliefs and behaviors that may help protect biodiversity.
Metaanálisis del efecto de la visita a acuarios y zoológicos sobre el conocimiento, creencias y comportamientos de conservación de los visitantes © 2024 by John Wiley & Sons, Inc. Resumen Los zoológicos y los acuarios están bien posicionados para conectar a los visitantes con temas mundiales de biodiversidad y varios cuentan con intervenciones que buscan influir las creencias y el comportamiento de los visitantes con respecto a la conservación. Sin embargo, con todo y los estudios primarios que evalúan el efecto de dichas intervenciones, aún no está claro el efecto general de participar en los zoológicos y los factores que influyen sobre este efecto. Realizamos una revisión sistemática para investigar el efecto de las intervenciones en los zoológicos sobre el conocimiento, creencias (actitud, intención, autosuficiencia y normas sociales) y comportamiento de sus visitantes. Usamos la teoría del comportamiento planeado como lente teórico para identificar los resultados. Identificamos y describimos la naturaleza de las intervenciones en los zoológicos en 56 estudios y usamos la taxonomía de las técnicas de modificación de conducta (TMC) para identificar seis TMC específicas que se usan hoy en día en dichas intervenciones. Los metaanálisis multinivel revelaron un efecto positivo de pequeño a mediano sobre los resultados causado por la participación en las intervenciones de los zoológicos (d+ = 0.40, 95% CI = 0.28 - 0.51). En específico, los visitantes fueron más conocedores sobre los temas de conservación, tuvieron actitudes más favorables hacia la conservación y reportaron tener mayor probabilidad de actuar en beneficio de la biodiversidad. No hubo evidencias de sesgos en las publicaciones. Sin embargo, el tamaño de los efectos fue heterogéneo y el análisis de los subgrupos reveló que la naturaleza de la intervención o el tipo de resultados no explicaban esta varianza. A pesar de esto, encontramos efectos más grandes en los estudios realizados en una sola institución en relación con la investigación realizada en varias instituciones y los estudios que usaron diseños intraparticipantes en relación a los que usaron diseños interparticipantes. Nuestra revisión demuestra cómo los marcos de modificación conductual pueden usarse para describir las intervenciones en los zoológicos y acuarios y respalda la aseveración de que estas instituciones pueden promover cambios en las creencias y el comportamiento que pueden ayudar a proteger la biodiversidad.
RESUMO
Zoos and aquaria are paying increasing attention to environmental enrichment, which has proven an effective tool for the improvement of animal welfare. However, several ongoing issues have hampered progress in environmental enrichment research. Foremost among these is the taxonomic bias, which hinders our understanding of the value of enrichment for neglected groups, such as reptiles. In this study, we evaluated the status of environmental enrichment for reptiles in European zoos using a survey approach. A total of 121 zoos (32% response rate) completed our main survey, focusing on the use of different enrichment types for reptiles. We found significant differences in the use and/or type of enrichment between reptile groups. Tortoises (family Testudinidae) and monitor lizards (genus Varanus) were the most enriched taxa while venomous snakes were the least. The enrichment types most used across taxa were structural/habitat design and dietary. A second, more detailed, questionnaire followed, where participants were questioned about specific enrichment techniques. A total of 42 enrichment methods were reported, with two being represented across all taxa: increasing structural/thermal complexity and enrichment objects. Finally, we present information from participating zoos on enrichment goals, assessment methods, sources of information for enrichment ideas, and whether enrichment for reptiles is considered essential and/or implemented routinely. Results suggest that, although usage is widespread across European zoos, our understanding of enrichment for reptiles needs to be re-evaluated, since many of the techniques reported tread a fine line between basic husbandry and actual enrichment.
RESUMO
Many species thrive in captivity, yet there is still much to be assessed regarding the often-unknown stressors present that can compromise welfare. Uncovering such stressors is of paramount importance if we are to ensure the zoo environment provides the highest levels of animal welfare that will contribute to species conservation. Zoo-housed primates are subject to many potential stressors, including daily husbandry routines which they may find aversive or habituate to, regardless of their outcome. The specific aim of this study was to assess the behavioral responses to daily husbandry feeding routines on a total of 33 Sulawesi crested black macaques (Macaca nigra), across two different UK zoological collections. Group scan sampling was used to record behaviors for 30-min periods before feeding (BF), for 30 min after feeding (AF), which we began 30 min after feed provision, and for 30 min when no feeding occurred (NF). The feeding condition significantly influenced behaviors recorded and post-hoc comparisons showed that BF conditions produced significantly higher frequencies of food anticipatory related activity (FAA). Furthermore, during BF periods, behaviors associated with FAA increased during the 15 min closer to a feed. This research finds that temporal feeding events cause changes in the behavior of two independent groups of crested macaques, indicative of food anticipation activity, during 30-min periods leading up to a feed. These results have implications for how animal keeper routines and advertised zoo feeds are managed for this species within zoological collections.

Zoo-based (ex situ) conservation breeding programs provide invaluable opportunities to uncover enigmatic behaviors and traits of focal species under managed care, which can support research and conservation management efforts. A suite of factors and a limited range have yielded population declines in the threatened narrow-headed gartersnake (Thamnophis rufipunctatus). Better understanding its cryptic ecology and life history (e.g., reproductive ecology) offers conservation benefits. We analyzed data on courtship behavior, parity and litter size, offspring size, and neonatal growth from an ex situ T. rufipunctatus population at the Phoenix Zoo from 2009 to 2018. Courtship behavior and parturition phenology are likely linked with the North American monsoon season, yet the courtship window may be wider than realized. We document the first instances of interannual iteroparity and multigenerational rearing of successful breeders at the ex situ level. Litter sizes varied but were relative to maternal body mass, suggesting that fecundity may be driven by intrinsic condition (e.g., age and size) of breeding females. Mean offspring body masses were equivalent between sexes, and neonate growth trends were quadratic during their first 9 months. Sexual dimorphism became apparent around 4-5 months age. Much of these data are novel for T. rufipunctatus and provide insight into their reproductive ecology. Phenology of reproductive ecology and body size metrics can guide field surveillance, age estimations, and population ecology monitoring, as well as inform ex situ adaptive management practices. Strategies spanning the ex situ-in situ spectrum are applicable to other imperiled taxa to better inform conservation management decisions.

In the past few decades, zoos have undergone a transformation from places of entertainment to centers for conservation, with education becoming a particular focus. Interpretation in zoos is a near-universal method for delivering education in zoos and has been shown to prompt learning and pro-conservation behavior change. However, there is limited understanding on how interpretation design itself can influence visitor engagement. Using unobtrusive visitor observations (n = 3890), this study measures visitor engagement of multiple pieces of interpretation with various design "traits," to provide a comprehensive overview of the key traits related to increased visitor engagement. The proportion of visitors who stopped at the interpretation (attraction power), and how long they stopped for (holding power), were our two outcome variables. From our models, we found that attraction and holding power are most strongly influenced by the type of interpretation, with interactive interpretation seeing nearly four times as many visitors stop, and for more than six times longer, when compared to standard text and graphics interpretation. We also found that location was significantly related to attraction power, with visitors more likely to stop at interpretation in more immersive exhibits. Lastly, interpretation containing images of humans were related to a higher holding power. We hope our findings will be used as a guide for designing interpretation that is both attractive and interesting to zoo visitors, maximizing the conservation education value of zoo-based interpretation.

The Raggiana Bird-of-paradise (Paradisaea raggiana) has been held by the San Diego Zoo for more than 50 years, but the population remained in low numbers until the mid-1990s. A previous article published in 1997 documented the beginning of the rise in the population; however, no new information has been published since that time. Over the past 25 years, behavioral observations by animal staff have led to improvements in husbandry techniques, which includes artificial incubation of eggs and hand-rearing of chicks. The ability to simulate a lek with various housing arrangements, in which the males can display with each other, be given access to a female for copulation, and then be separated again has proven paramount for breeding success. Additionally, females are allowed mate choice, further mimicking natural behaviors observed by this species. The refinement of these methods has led to a greater number of fertile eggs as well as higher hatchability and survivability, which in turn has resulted in a significant increase in the captive population.

Zookeepers working with felids were asked to complete an online survey to examine their perceptions of animal welfare. A total of 121 zookeepers in an AZA-accredited zoo completed the survey. Results from this study suggest that institutional offerings of professional development programming in animal welfare have the greatest potential to influence zookeeper perceptions of animal welfare. Participants also identified four areas of improvement for felid welfare, including 1) larger and more dynamic spaces, 2) increased attention to behavioral husbandry, 3) more unique diet presentations, and 4) the ability for the animal to remain out of the view of the public. In addition, there appear to be differences in perception between traditionally described "small cat" and "large cat" keepers in terms of the ability to deliver the Five Freedoms.

Zoos and natural history museums are both collections-based institutions with important missions in biodiversity research and education. Animals in zoos are a repository and living record of the world's biodiversity, whereas natural history museums are a permanent historical record of snapshots of biodiversity in time. Surprisingly, despite significant overlap in institutional missions, formal partnerships between these institution types are infrequent. Life history information, pedigrees, and medical records maintained at zoos should be seen as complementary to historical records of morphology, genetics, and distribution kept at museums. Through examining both institution types, we synthesize the benefits and challenges of cross-institutional exchanges and propose actions to increase the dialog between zoos and museums. With a growing recognition of the importance of collections to the advancement of scientific research and discovery, a transformational impact could be made with long-term investments in connecting the institutions that are caretakers of living and preserved animals.
RESUMO
Since first brought into zoos in 1964, the captive population of Superb Bird-of-paradise (Lophorina superba) has remained relatively small. Several decades of artificial incubation and hand-rearing of this species at the Avian Propagation Center (APC) at the San Diego Zoo has allowed the population to increase and maintain some stability. Successful artificial incubation techniques lead to healthy neonates and allow females to reproductively recycle and produce more offspring in a season. Additionally, hand-rearing methods have been refined over the years at APC and are shown here as a method that could be employed to help sustain other small populations of birds maintained in zoological institutions.

Mimicking natural parameters and complexities in zoo conservation breeding programs can facilitate natural physiological and behavioral traits, which in turn can inform more effective species reintroduction efforts. To curtail population declines of threatened narrow-headed gartersnakes (Thamnophis rufipunctatus), the Arizona Center for Nature Conservation/Phoenix Zoo partnered with a multiagency conservation working group to develop an ex situ propagation-for-release program. Initially, Zoo staff followed common snake husbandry protocols of manually inducing brumation (i.e., winter dormancy). Copulation was observed during the first few years, but no births resulted. Also, some older individuals developed post-brumation health abnormalities, prompting a strategic reassessment. To facilitate propagation and improve health, Zoo staff applied ecological knowledge of T. rufipunctatus and an adaptive management strategy to implement key parameters for success: sociality, refugia, breeding and foraging behaviors, and natural brumation. Zoo staff developed a large multisnake enclosure that mimicked natural ecological and habitat complexities including a hibernaculum to stimulate natural brumation. Gartersnakes were left mostly unimpeded to conduct natural behaviors across seasons in the enriched environment. We referenced change in body mass after ten brumation periods as a proxy for health. Under natural brumation, gartersnakes did not lose body mass, and this shift resulted in fully ex situ parturition events-the first for this imperiled species. We highlight the efficacy of adaptive management and incorporation of natural parameters and environmental complexities into conservation breeding programs. These actions can improve the health and success of animals under managed care-processes applicable to a range of taxa targeted for conservation translocations.

The global reach of zoos has enormous potential to raise awareness of conservation issues such as the amphibian extinction crisis. One mechanism of achieving this is through targeted, time-limited campaigns. However, the longer-term impact of such campaigns on conservation outcomes is rarely evaluated. The goal of this study is to evaluate how zoos view "The Year of The Frog," a campaign launched by zoos in 2008, with the aim of raising awareness of the global amphibian crisis and generating funds to support amphibian conservation initiatives. A questionnaire-based survey of 43 zoos from fourteen countries was used to evaluate how zoo practitioners believed the campaign influenced amphibian conservation some 10 years after its launch. Survey results showed that the campaign not only contributed to the improvement of research into amphibian husbandry in zoos but also increased support of in situ conservation of amphibians. Zoos focused on exotic species, but developed countries led most of the actions of the campaign. The campaign has inspired and encouraged some zoos and other ex situ conservation organizations to embrace amphibian conservation. The next step is to increase collaboration with more organizations through, for example, AArk and IUCN SSC/ASG, particularly in countries that have high amphibian biodiversity.

Conservation first appeared as a role for zoos and aquariums in the late 20th century, and over the past few decades has evolved to be central to the mission of modern, accredited zoos and aquariums (henceforth zoos). More recently, promoting proenvironmental behavior is increasingly recognized as an essential means for zoos to achieve their shared conservation mission. To support continued progress throughout the field, there is a need for greater clarity and confidence regarding successful approaches for promoting proenvironmental behavior. A growing body of research into the conservation-related outcomes of zoo experiences, along with findings from behavioral and social sciences, provides a basis for understanding how the relationship zoos have with their audiences can translate into measurable conservation results. By shifting the balance between motivation to act and barriers to actions so that motivation is the greater force, zoos can tip the behavior balance to successfully promote action on behalf of nature and wildlife. Zoo audiences are, on average, more intrinsically motivated to take action on behalf of wildlife than the public at large. By introducing extrinsic motivators and reducing barriers, zoos can set up the circumstances that move motivated individuals to take conservation action. Even individuals who lack intrinsic motivation can be moved to action through sufficiently attractive extrinsic benefits and low barriers. In this paper we present a framework that synthesizes this study and theory on environmental behavior change and offers actionable approaches for zoo and aquarium practitioners.

Zoos and aquaria, often regarded as preservation-cum-entertainment enterprises, are also actors in the effort to curb the biodiversity crisis: raising awareness, supporting conservation, and conducting research. We assessed trends in zoo and aquaria research topics and study organisms over time worldwide. For the zoos and aquaria registered in the Species360's Zoological Information Management System and the World Association of Zoos and Aquariums, we compiled metadata on their research published in the peer-reviewed literature indexed in Scopus and carried out a keyword frequency analysis. The production of scientific papers by zoos increased at a much faster rate than the average accrual of scientific papers in the literature. Evolution of research themes ran parallel to that of biological sciences (e.g., development of molecular genetics or increased awareness about conservation). The focus of 48.5% of zoo-led research was on vertebrates, of which mammal research was 33.7%. Whether zoos are effectively contributing to conservation may still be debatable, but our results highlight their institutional efforts to increase knowledge about the species in their care.
Tendencias Mundiales en la Producción Investigativa de los Zoológicos y Acuarios Resumen Los zoológicos y los acuarios, con frecuencia considerados empresas de conservación y entretenimiento, también son actores en el esfuerzo por reducir la crisis de la biodiversidad al crear conciencia, apoyar a la conservación y llevar a cabo investigaciones. Evaluamos las tendencias en los temas de investigación y los organismos de estudios en los zoológicos y los acuarios en todo el mundo a través del tiempo. Compilamos los metadatos de las investigaciones realizadas en los zoológicos y acuarios registrados en el Sistema de Manejo de Información Zoológica de Species360 y en la Asociación Mundial de Zoológicos y Acuarios que han sido publicadas en la literatura revisada por pares indexada en Scopus y realizamos un análisis de frecuencias de palabras clave. La producción de artículos científicos por zoológicos se incrementó a una tasa mucho más rápida que la acumulación promedio de artículos científicos en la literatura. La evolución de los temas de investigación fue paralela a la de las ciencias biológicas (p. ej.: desarrollo de la genética molecular o incremento en la conciencia por la conservación). El enfoque del 48.5% de las investigaciones conducidas por los zoológicos estuvo sobre los vertebrados. De este 48.5%, el 33.7% fueron investigaciones sobre mamíferos. Todavía puede debatirse si los zoológicos están contribuyendo efectivamente a la conservación, pero nuestros resultados resaltan sus esfuerzos institucionales por incrementar el conocimiento sobre las especies bajo su cuidado.

The Superb Bird-of-paradise (Lophorina superba) has been bred in captivity for more than 50 years but has not been well documented. San Diego Zoo began efforts to breed the Superb Bird-of-paradise in the late 1960s. Through the years, behavioral observations by animal staff have led to improvements in husbandry techniques which have led to increased reproductive success. Enclosure setup and pair management are particularly important. The ability to maintain breeding pairs in adjacent enclosures, in which the male can maintain visual contact with the female, establish a territory, be given access to a female for copulation and then be separated again has proven paramount for nesting success. Additionally, diet and planned timing of introduction have played a beneficial role for successful breeding year after year.

Zoo veterinarians and allied professionals have been contributing to conservation medicine (CM) and One Health (OH) activities for more than two decades. Although the Association of Zoos and Aquariums (AZA) considers conservation a key part of its mission, little published material exists about the extent of AZA work in CM/OH or the challenges and opportunities associated with these endeavors. To better understand the current scope of CM/OH in zoos, we surveyed 53 AZA-accredited institutions from April through October of 2016. We obtained information on CM/OH infrastructure, support for expansion in this area, and strategies to overcome perceived obstacles hindering CM/OH from becoming a core AZA activity. Survey results revealed that while most zoos favor greater investment in CM/OH programs, awareness, and understanding of CM/OH across the broader zoo community and public is lacking. The majority of respondents stated that overcoming this challenge is paramount to attaining support for CM/OH initiatives. In spite of these obstacles, survey respondents highlighted many positive developments in CM/OH. We found that 84% of zoos surveyed are actively engaged in CM/OH activities, and 12% house formal CM/OH programs. Another 8% of respondents said their institutions were developing CM/OH programs. Perhaps most noteworthy, we found that zoo size did not have a significant bearing on the financial amount allocated toward an institution's CM/OH activities. This suggests that all zoos, regardless of size, can make meaningful contributions to the growing movement of CM/OH and help redefine the role of zoos within this movement.

Maintaining a living plant collection is the most common method of ex situ conservation for plant species that cannot be seed banked (i.e., exceptional species). Viability of living collections, and their value for future conservation efforts, can be limited without coordinated efforts to track and manage individuals across institutions. Using a pedigree-focused approach, the zoological community has established an inter-institutional infrastructure to support long-term viability of captive animal populations. We assessed the ability of this coordinated metacollection infrastructure to support the conservation of 4 plant species curated in living collections at multiple botanic gardens around the world. Limitations in current practices include the inability to compile, share, and analyze plant collections data at the individual level, as well as difficulty in tracking original provenance of ex situ material. The coordinated metacollection framework used by zoos can be adopted by the botanical community to improve conservation outcomes by minimizing the loss of genetic diversity in collections. We suggest actions to improve ex situ conservation of exceptional plant species, including developing a central database to aggregate data and track unique individuals of priority threatened species among institutions and adapting a pedigree-based population management tool that incorporates life-history aspects unique to plants. If approached collaboratively across regional, national, and global scales, these actions could transform ex situ conservation of threatened plant species.
Aplicación del Modelo Zoológico a la Conservación de Especies Excepcionales de Plantas Amenazadas Resumen El mantenimiento de una colección de plantas vivas es el método más común para de conservación ex situ para especies de plantas que no pueden almacenarse en bancos de semillas (i. e., especies excepcionales). La viabilidad de las colecciones vivientes, junto con el valor que representan para los futuros esfuerzo de conservación, puede estar limitada si no existen esfuerzos coordinados para rastrear y manejar a los individuos entre las instituciones. Mediante una estrategia enfocada en el linaje, la comunidad de zoológicos ha establecido una infraestructura interinstitucional que respalda la viabilidad a largo plazo de las poblaciones de animales en cautiverio. Evaluamos la habilidad de esta infraestructura coordinada de metacolecciones para apoyar en la conservación de cuatro especies de plantas curadas en colecciones vivientes en varios jardines botánicos de todo el mundo. Las limitaciones de las prácticas contemporáneas incluyen la incapacidad de recopilar, compartir y analizar los datos de las colecciones de plantas a nivel individual, así como la dificultad de rastrear la procedencia original del material ex situ. El marco de trabajo de metacolecciones coordinadas que utilizan los zoológicos puede ser adoptado por la comunidad botánica para mejorar los resultados de conservación al minimizar la pérdida de la diversidad genética que ocurre en las colecciones. Sugerimos acciones que aumenten la conservación ex situ de las especies excepcionales de plantas. Estas acciones incluyen el desarrollo de una base de datos central para acumular datos y rastrear entre las instituciones a los individuos únicos de las especies amenazadas prioritarias y la adaptación de una herramienta de manejo poblacional basada en el linaje que incorpore los aspectos únicos de la historia de vida de las plantas. Si estas acciones se plantean colaborativamente a escala regional, nacional y global, podrían transformar la conservación ex situ de las especies amenazadas de plantas.

With the loss of biodiversity accelerating, conservation translocations such as reintroductions are becoming an increasingly common conservation tool. Conservation translocations must source individuals for release from either wild or captive-bred populations. We asked what proportion of North American conservation translocations rely on captive breeding and to what extent zoos and aquaria (hereafter zoos) fulfill captive breeding needs. We searched for mention of captive breeding and zoo involvement in all 1863 articles included in the North American Conservation Translocations database, which comprises journal articles and grey literature published before 2014 on conservation translocations in Canada, the United States, Mexico, the Caribbean, and Central America before 2014 as identified by a comprehensive literature review. Conservation translocations involved captive breeding for 162 (58%) of the 279 animal species translocated. Fifty-four zoos contributed animals for release. The 40 species of animals bred for release by zoos represented only 14% of all animal species for which conservation translocations were published and only 25% of all animal species that were bred for releases occurring in North America. Zoo contributions varied by taxon, ranging from zoo-bred animals released in 42% of amphibian conservation translocations to zero contributions for marine invertebrates. Proportional involvement of zoos in captive-breeding programs for release has increased from 1974 to 2014 (r = 0.325, p = 0.0313) as has the proportion of translocation-focused scientific papers coauthored by zoo professionals (from 0% in 1974 to 42% in 2013). Although zoos also contribute to conservation translocations through education, funding, and professional expertise, increasing the contribution of animals for release in responsible conservation translocation programs presents a future conservation need and opportunity. We especially encourage increased dialogue and planning between the zoo community, academic institutions, and governments to optimize the direct contribution zoos can make to wildlife conservation through conservation translocations.

In the past few decades, there has been an increase in the number of zoo-based touchscreen studies of animal cognition around the world. Such studies have contributed to the field of comparative cognition despite the fact research has only been performed at a relatively small number of institutions and with a narrow range of species. Nonetheless, zoo-based touchscreen studies are increasingly recognized as both having the potential to be enriching for captive animals by providing them with opportunities for choice, as well as potentially being a tool with which to measure changes in welfare. Zoo-based touchscreen research on public display also has the potential to impact zoo visitors; encouraging them not only learn more about the cognitive abilities of animals, but also potentially promoting increased respect for these species. Given the lack of a comprehensive review of this scope of specialized research, and the broad potential impacts on animals and programs, here we discuss the history, implementation, and potential outcomes of touchscreen research in zoo settings.

The "sustainability crisis" in zoos and aquariums has been a sobering reminder of how limited our resources are for maintaining viable populations of species threatened with extinction. This, combined with increasing concern among the public about the value of zoos and aquariums, suggests that the zoological profession should engage in a thorough re-examination of our guiding principles, philosophies, and practices with regard to collection planning at global, regional, and institutional scales. An analysis of AZA cooperative breeding programs reveals that in order to make these populations viable, many more founders and tens of thousands more spaces for animals, either in existing facilities or new ones, are necessary if we want to maintain all of the species that are covered by cooperative breeding programs currently. Regional zoological associations and their associated cooperative breeding programs must be more strategic and make more scientifically defensible decisions about which species to try and safeguard in zoos and aquariums. This would enable the zoological profession to give society a "Promise List" of species that we will commit to save from total extinction. Developing such a list will require a collaborative, inclusive process that transcends zoological regions. Regional association leaders, zoo & aquarium directors, and curators must make commitments to safeguard the species on the Promise List regardless of other interests. As our profession re-examines its philosophies and practices and finds ways to increase its capacity to provide refuge for species facing extinction in the wild, it may be possible to expand the Promise List.

The modern zoo has brought about two major advances in the behavioral welfare of their exhibited animals: (a) The use of environmental enrichment to promote naturalistic behaviors and (b) the use of training to improve voluntary husbandry care. Whereas training itself has been talked about as an effective enrichment strategy, little has been done to combine training procedures with enrichment. Typically, enrichment is treated as a trial and error process, where potential enrichment items or procedures are cycled through until successful enrichment is found. The use of shaping or other training techniques has seldom been documented to increase engagement with possible enrichment items or procedures. The following study examined the possibility of combining training and enrichment to produce continued interactions with enrichment devices. Two species of penguin, Magellanic and southern rockhopper penguins, were studied. Two measures were taken: Time spent swimming and contact with enrichment devices. The enrichment devices could be manipulated by placing fish within and hanging out of each device. During baseline sessions, no hits to either device were observed. During training sessions, several hits were recorded when fish were in the devices and overall swimming time increased during these conditions. When baseline was reintroduced without fish in the devices, contact with the enrichment devices rapidly declined and swimming time for the rockhopper penguins decreased. When the devices were reintroduced with fish but without training, the greatest number of enrichment device contacts and the highest percentage of time spent swimming were observed for the rockhopper penguins.
