Meet our grantees
Wild Animal Initiative funds academic research on high-priority questions in wild animal welfare.
The goal of our grants program is to fund research that deepens scientific knowledge of the welfare of wild animals in order to better understand how to improve the welfare of as many wild animals as possible, regardless of what causes the threats to their well-being.
We showcase our grantees and their projects here and continuously update this page as new projects are added.
Validating the use of cognitive bias to assess affective valence in wild bird populations.
Grantee: Oliver Burman
Institution: University of Lincoln
Project summary
The goal of this project is to develop and validate a cognitive bias test for assessing the welfare of woodland birds that does not require any training stage, and instead takes advantage of innate attraction and aversion to stimuli that resemble preferred or noxious prey (with a range of likeness accuracy, based on the principle of imperfect Batesian mimicry). Continuing the theme of exploiting natural variation, the project will use spatial variation in numerous components of habitat preferability that can be assumed to directionally affect welfare — such as food abundance and shelter — as natural experiments to validate their cognitive bias tests.
Integrating behavioral competency and post-release support for reintroduced wildlife: a shift in paradigm for rehabilitation and beyond
Grantee: Karli Rice Chudeau
Institution: The Marine Mammal Center, University of California, Davis
Project summary
This project investigates post-release support and monitoring to improve outcomes for rehabilitated juvenile pinnipeds. Post-release support will include familiar cognitive enrichment to help released animals adjust gradually and buffer their affective state. Post-release monitoring will consider metrics such as behavioral diversity, energy expenditure, and body condition, and the animals’ specific behavioral profiles will be compared with those recorded from healthy, wild individuals. These metrics will be used to evaluate the effectiveness of post-release enrichment as an intervention for improving welfare outcomes. Cognitive bias tests for affective state carried out during rehabilitation and prior to release will also be considered as potential predictors of post-release welfare.
Social connections and their welfare implications in the wild
Grantee: Alex Thornton
Institutions: University of Exeter, University of Bristol
Project summary
This project seeks to understand the relationship between welfare and social interactions in wild bird populations. Using historical data, the researchers will also seek insight into how welfare varies among individuals in relation to the social system, early-life experiences, and interactions among individuals. They will also investigate whether social systems might play a role in helping to mitigate some of the negative anthropogenic impacts on welfare.
Paying to play? Social time allocation, emotional contagion, and social attention as assays of welfare in wild animals
Grantee: Patrick Tkaczynski
Institution: Liverpool John Moores University
Project summary
Play and grooming have a number of facets that could be potential indicators of positive welfare in group-living vertebrates, but analysis of such behaviors are yet to be put into a formal framework for monitoring wild animal populations. This pilot project will focus on six different wild Barbary macaque groups of variable sizes and facing varying degrees of human exposure, which is typically associated with poor health outcomes in wild animals. It will use play and grooming behavior to quantify social time allocation, emotional contagion/synchronization, and social attention as potential assays of positive welfare. Once validated, these assays can be applied to examine how positive welfare varies across different gradients, such as climate change or variation in predator pressure.
Developing an approach for assessing the welfare of wild birds through the use of bioacoustics analysis
Grantee: Luiza Figueiredo Passos
Institution: Liverpool John Moores University
Project summary
Vocalization analysis has been used to monitor the welfare of farmed animals and animals in laboratories, but lacks validation for wild animals. This project will use passive acoustic monitoring to record wild bird calls throughout the UK. It will identify vocal patterns and chorus characteristics related to various environmental risks that can be used to infer the welfare status of local bird populations across multiple environments. The focal species will be house sparrows, who have undergone a massive population decline and may be facing welfare challenges. Validating acoustic monitoring as a tool for non-invasive welfare monitoring in the wild for the first time will provide a method that could be used to monitor the welfare of wild birds globally.
Assessing animal welfare from bioacoustic monitoring in red-billed choughs (Pyrrhocorax pyrrhocorax)
Grantee: Claudia Wascher
Institution: Anglia Ruskin University
Project summary
Bioacoustic monitoring is a well established method of measuring welfare in captive animals, but has not been used in wild animals. This project will assess and validate the use of passive bioacoustic monitoring to assess welfare in a reintroduced population of red-billed choughs. The researchers will conduct a combination of automatic acoustic monitoring using “passive” acoustic recorders and direct observations (recording behavior via videos and monitoring activity during the night with night vision scopes) and “active” acoustic monitoring, using a high-quality directional microphone and parabolic dish. Their approach will allow them to record vocalizations and behavior during natural events expected to influence welfare, such as anthropogenic noise, predation events, intraspecific aggression, resting, or affiliative behaviors.
A bird’s eye view to the five domains of welfare: a quantitative framework and proof-of-concept evaluation in a cetacean, Orcinus orca
Grantees: Saana Isojunno, Eve Jourdain
Institutions: University of St. Andrews, Norwegian Orca Survey
Project summary
This project will carry out body condition and welfare assessments for inshore-foraging killer whales in the northeast Atlantic. The researchers will use the Five Domains model to categorize likely factors influencing killer whale welfare and quantify some of those factors using aerial photography from drones. They will gather data on foraging time and feeding rates, group composition and surface behavior, body shape as a proxy for body condition and blubber reserves, and reproductive success. The researchers will then develop a proof-of-concept statistical model to infer latent motivational states beneath the observable data. The project will also utilize data from known cases of poor welfare to help define their welfare scale.
Mapping welfare for conservation management
Grantee: Lisa Olivier
Institution: Game Rangers International
Project summary
This project will monitor behavioral and physiological parameters in African elephants over one year to map their perception of their environment. The aim is to test this approach’s potential as a leading indicator that is easy to measure, responds quickly to ecosystem changes, and highlights potential detrimental impacts. These measures will be aggregated to define a scale representing the animals’ perceptions of threat that can be estimated for a given time and place. The researchers will then project this data onto maps to identify areas of high and low welfare. The project will help conservation practitioners create management plans to protect wild animals by providing a head start in assessing changes in their surroundings.
Every breath you take, I‘ll be watching you: Automated measurement of breath rate from mobile phone videos as a severity assessment parameter in wild great tits
Grantee: Caroline Deimel
Institution: Max Planck Institute
Project summary
This project aims to provide a validated reference tool for standardizing breath rate (BR) measurements following capture and physical sampling protocols in wild birds. The researchers will use computer vision capabilities and other recently developed software improvements to estimate BR metrics from mobile phone videos, enabling the collection of objective, reproducible, and comparable data, and providing institutions tasked to oversee animal welfare with objective and feasible monitoring requirements. The project will also evaluate BR as a welfare indicator in great tits by analyzing an existing five-year dataset to test whether BR corresponds to simultaneous glucocorticoid measurements from free-living great tits. This data will provide reliable baselines and ranges for glucocorticoids and BR, and benchmarks for video recording lengths.
City living – assessing the welfare costs of urban living in spotted hyaena (Crocuta crocuta)
Grantee: Emma Stone
Institutions: Carnivore Research Malawi, University of the West of England
Project summary
Networks of green spaces and river corridors support a population of urban spotted hyenas in Lilongwe City, Malawi. However, human-wildlife conflict (HWC) is frequent. Using non-invasive techniques, this project will measure and compare the fecal and hair cortisol levels, mean body condition, tooth ware, hematological parameters, and disease in urban and rural populations of spotted hyenas. Behavioral experiments (exposure to novel objects and threatening scents) will also be used to assess individual boldness in urban and rural populations as a risk factor, which may increase propensity for HWC and therefore mortality and stress. Results will be used to inform policies to reduce HWC and implement welfare considerations as part of the population’s conservation management plan.
