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.
Thermal imaging as a non-invasive welfare assessment tool for tracking the impact of environmental stressors across wild animal populations
Grantee: Ross MacLeod
Institution: Liverpool John Moores University
Project summary
This project aims to test and validate a standardized multi-species approach to monitoring physiological stress in wild birds by using thermal imaging cameras to measure the animals’ body surface temperature, which could enable tracking of chronic stress in wild populations facing environmental stressors. Building on pilot work, the project will focus on wild bird populations to develop a standardized thermal imaging methodology capable of monitoring surface temperature of a wide range of wild animals. The methodology will be validated using bird communities visiting 54 standardized feeding and drinking stations spread across the UK, to quantify how changes in surface temperature are linked to starvation risk, predation risk, and human disturbance.
Raman spectroscopy as a novel non-invasive technique to assess wildlife welfare
Grantee: Teresa Romero
Institutions: University of Lincoln, University of Portsmouth
Project summary
Analysis of hormones accumulated in the hair has emerged as a non-invasive tool for measuring chronic stress in wildlife, but hair analyses are currently limited by variation in cortisol concentrations. This project will test whether Raman spectroscopy, which is suitable for the field and does not require sample pre-treatment, is a better way to use hair samples to assess steroid hormones. The planned methodology will make use of samples of mammalian hair with a known cortisol content using a control technique — liquid chromatography mass spectrometry — for comparison. The samples will be subjected to analysis by Raman to validate the technique and establish a robust analytical methodology for the non-invasive analysis of welfare biomarkers in wildlife.
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.
Investigating ways to assess and improve the welfare of leopards captured in response to conflict, in Nepal
Grantee: Jessica Bodgener
Institutions: University of Kent, Wildlife Vets International
Project summary
In Nepal, the successful recovery of tiger populations is displacing leopards from protected parks and forcing them into urban areas. This has caused an increase in conflict with people and farmed animals. Organizations responding to conflicts have limited resources and must attempt to balance animal welfare and conservation aims with public safety and sociopolitical demands. This has resulted in an ad hoc approach, with frequent interventions but little opportunity to evaluate their success. This project will focus on validating non-invasive post-release monitoring techniques, including photogrammetric assessment of body condition and measurement of hair cortisol from fecal samples, to monitor the welfare impact of translocation of leopards away from conflict areas.
The animal welfare of animal warfare: how inter-group interactions affect wild animal wellbeing
Grantee: Dominic Cram
Institution: University of Cambridge
Project summary
This project will investigate the welfare consequences of inter-group conflicts in wild Kalahari meerkats. It will use an established dataset of meerkat behavior, body weight, territory use, and reproduction, covering more than 500 inter-group interactions over 14 years. Identifying the short- and long-term welfare implications of inter-group interactions in meerkats will shed light on similar animal warfare in group-living insects, fish, birds, and mammals. Clarifying the circumstances that lead to the most harmful battles will provide a first step in understanding how their frequency could be reduced, which could limit the suffering they cause and enhance the welfare of group-living wild animals.
Development of novel measures of welfare in juvenile European starlings exposed to nutritional stress
Grantee: Melissa Bateson
Institution: Newcastle University
Project summary
Nutritional stress causes massive mortality in juvenile European starlings and has lifetime welfare consequences for survivors. The aim of this project is to identify the metabolic “fingerprint” of nutritional stress in starling nestlings and to validate molecular biomarkers that can be used to assess the welfare of wild starlings. This project will use untargeted metabolomics to identify multiple novel biomarkers of exposure to nutritional stress. This “fingerprint” will be validated by testing whether it predicts gold-standard behavioral measures of adult affective experience in a cohort of laboratory-raised birds. The aim will be to identify an applicable panel of metabolites that can be measured from feathers and guano.
It takes guts to grow in the city: the role of the gut microbiome in the welfare of juvenile urban birds
Grantee: Pablo Capilla-Lasheras
Institution: University of Glasgow
Project summary
Approximately 30 million blue tits hatch every year in UK cities, but around 63% die as juveniles. One reason for this may be that juvenile birds in urban habitats tend to have low-quality diets, causing stunted growth and increased early-life mortality. Research suggests that gut microbiome composition may contain indicators of an animal’s welfare, but this has received little attention in a wild animal context. This project will combine telomere attrition, begging behavior, and other health metrics with a study of juvenile birds’ gut microbiomes to investigate how to improve the welfare of juvenile blue tits in urban areas. It will also test the potential for gut microbiome enrichment to improve the life experience of juvenile birds in urban habitats.
