Staff perceptions of COVID-19 impacts on wildlife conservation at a zoological institution

Impacts of the COVID-19 pandemic on population management in AZA

Soon after the onset of the COVID-19 pandemic, almost all Association of Zoos and Aquariums (AZA) facilities closed to the public. Resulting cost-saving and safety measures led some facilities to temporarily cease or reduce animal breeding and/or transfers. We surveyed AZA facilities and Species Survival Plan® (SSP) Coordinators for AZA's cooperative population management programs to evaluate how widespread these decisions were, if impacts varied by taxa, and how the AZA community navigated related challenges during the pandemic. We found that 60% of responding facilities did not suspend breeding and 22% did not suspend transfers. About 50% of responding zoos increased their reliance on ground transportation to move animals, while aquariums reported no change to transportation methods. SSP Coordinators reported the main reason why breeding decreased, regardless of taxa, was due to canceled or delayed transfers. The reasons transfers decreased differed by taxa, such as limited financial resources and lack of access to air transportation. The majority of respondents for both surveys stated transfers were the greatest challenge they faced. To address this, facilities utilized alternative transportation methods and worked closely with nearby zoos and aquariums for the movement of animals, while SSP Coordinators issued alternative transfer recommendations. If another pandemic or other widespread facility closure occurs, our research highlights the importance of communication, collaboration, and flexibility to fulfill breeding and transfer recommendations to maintain sustainable zoo and aquarium populations.

Multi-species outbreak of SARS-CoV-2 Delta variant in a zoological institution, with the detection in two new families of carnivores

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a worldwide distribution in humans and many other mammalian species. In late September 2021, 12 animals maintained by the Chicago Zoological Society's Brookfield Zoo were observed with variable clinical signs. The Delta variant of SARS-CoV-2 was detected in faeces and nasal swabs by qRT-PCR, including the first detection in animals from the families Procyonidae and Viverridae. Test positivity rate was 12.5% for 35 animals tested. All animals had been vaccinated with at least one dose of a recombinant vaccine designed for animals and all recovered with variable supportive treatment. Sequence analysis showed that six zoo animal strains were closely correlated with 18 human SARS-CoV-2 strains, suggestive of potential human-to-animal transmission events. This report documents the expanding host range of COVID-19 during the ongoing pandemic.

Communication from the Zoo: Reports from Zoological Facilities of the Impact of COVID-19 Closures on Animals

Zoos engaged in a range of communication types with prospective visitors during the temporary closures necessitated by the COVID-19 pandemic. This study sought to (1) investigate social media reports and public responses to zoo-animal-related posts over a one-year period during COVID-19 lockdowns; (2) understand the use of reporting language in news articles concerning animal responses during zoo closures, and to investigate whether this differed across species; and (3) investigate how keepers perceived general animal behavior, and how they perceived animal behavior in keeper–animal interactions, during the COVID-19 facility closures. Data were collected from BIAZA-accredited zoos’ Facebook pages (March 2020 to March 2021) and news reports (Google search outputs from 20 March to 5 April 2021). Keeper perceptions were captured via questionnaires (May to August 2021). Data were collected on taxa, the reported behavioral changes and the language used in media communications. In Facebook posts and news reports, mammals were more frequently represented than was expected (p < 0.05). Behavioral responses were more frequently negative (p < 0.05) and less frequently positive or neutral (p < 0.05). Keepers reported overall behavioral changes, as well as changes during their own interactions with animals. On Facebook, mammals were described using a combination of behavioral descriptions and anthropomorphic terms, which were used more frequently than was expected (p < 0.05). In the news reports concerning primate species, anthropomorphic descriptions were used more frequently than expected (p < 0.05), while behavioral descriptions were used less frequently than expected (p < 0.05). The reports regarding the Carnivora were the reverse of this. This study enabled an understanding of the impact of the temporary closures on the animals, and how this impact was communicated to the public. The findings may reflect the relationships that humans have with animals and the need for communication methods that will capture visitors’ interest and induce empathy with the various species.
