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.
Does diet mediate effects of sublethal parasitic infections on host welfare?
Grantee: Amanda Koltz
Institution: University of Texas at Austin
Project summary
This project will test how infection by parasitic worms (helminths) influences host welfare in white-footed deer mice by evaluating the relationship between parasite burden and host body condition, microbiome, and stress physiology, as well as behaviors associated with anxiety (negative welfare) and exploration (positive welfare). The researchers will experimentally manipulate parasite burden by intervening to apply anti-parasitic medication (Ivermectin) as a treatment for some mice who were already infected with helminths.

Conservation status: Least concern
Disciplines: Infectious disease, animal welfare science, animal behavior, physiology, community ecology
Research location: United States
Project summary
Parasite-mediated changes in host traits can have far-reaching ecological effects. Even sublethal infections affect hosts by increasing energetic costs and altering behavior, immunity, and physiology. Yet while many studies have investigated parasite effects on specific host traits, our understanding of how parasites influence overall individual welfare is limited, especially for wild animals. For example, parasites can drive changes in host diet and habitat use that reduce parasite exposure but not necessarily improve other metrics of host welfare. A holistic approach that captures different types of individual-level responses to parasitism is needed to advance our overall understanding of sublethal infections on host welfare. We propose to investigate how parasite burden is associated with individual-level host welfare using white-footed deer mice (Peromyscus leucopus) and their helminth parasites as a model system. Specifically, by experimentally removing gastrointestinal helminth parasites from P. leucopus, we will test how variation in parasite burden influences individual host body condition, diet and nutrition, microbiome, stress physiology, anxiety-like behavior, and exploratory behavior in forested ecosystems. P. leucopus has become the dominant small mammal species over the last 40 years in the northern Great Lakes region. It experiences sublethal infection by a range of helminth parasites and is a reservoir for several zoonotic pathogens, making its host-parasite dynamics highly relevant to the health of humans and other wildlife. By examining how infection levels relate to the diet, body functions, and behavior of P. leucopus, this study will advance our understanding of how non-lethal parasitic infections affect the welfare of an extremely widespread wild animal species.
Why we funded this project
We are excited to fund a study on wild mice, a highly numerous and neglected group, and especially one with such a welfare-friendly experimental approach — curing parasitic infections rather than causing them. The project also uses a holistic suite of physiological and behavioral indicators that should allow the researchers to disentangle overall welfare from narrow, mechanistic impacts of infection on the health and nutrition domains.
Developing an automated cognitive bias task for wild squirrels
Grantees: Vikki Neville, Lisa Leaver
Institutions: University of Bristol, University of Exeter
Project summary
The goal of this project is to develop a cognitive judgment bias test for use in wild gray squirrels that capitalizes on their innate behavior, avoiding the need for the extensive type of training that is usually part of cognitive judgment bias tests in captive settings. By making use of the widely available Raspberry Pi platform, the test should be relatively easy for other researchers to replicate and adapt for use in other species. To validate the test itself, the research team will also assess how measurement of cognitive judgment bias varies with factors assumed to affect the valence of animals participating in the test, such as distance from cover and levels of food provisioning in the environment, as well as how the test results correlate with other potential non-invasive behavioral and physiological indicators of welfare, such as the distance at which a squirrel flees from approaching humans, hair cortisol concentration, and real-time fluctuations in eye temperature in response to stimuli during the the test.

Focal species: Grey squirrel (Sciurus carolinensis)
Conservation status: Least concern
Disciplines: Animal welfare science, physiology, animal behavior
Research location: United Kingdom
Project summary
The development of the cognitive judgment bias (CJB) task for non-human animals revolutionised the field of animal welfare. The CJB task: (a) is thought to measure both relatively better and relatively poorer welfare across the full spectrum of possible welfare states, (b) is non-invasive, and (c) has been validated using a meta-analytic approach. Moreover, the theoretical basis of the predictions for the CJB task should be applicable across taxa and, accordingly, it has been used successfully in many species. However, to date, its use has largely been in captive species and there are a dearth of examples in wild animals. A key barrier to implementation is that it is difficult to train animals to associate stimuli with particular outcomes: the time needed to do so makes these studies unsuccessful or infeasible in non-captive populations of animals. We propose that this could be overcome by capitalising on the natural behaviour of a species to reduce training time and by using equipment that allows automation of stimulus presentation and data collection.
The main aim of our proposed project is to develop a CJB task for use in wild animals, in particular wild squirrels. Our key objectives are to develop a task for collecting CJB data from grey squirrels which: (1) capitalises on their innate behaviour, obviating the need for extensive training, and (2) makes use of Raspberry Pi equipment so that the task can be easily implemented by other researchers and straightforwardly adapted for use across species to measure welfare and validate novel potential measures of welfare.
To assess that our task works as anticipated, secondary objectives will be to: (1) assess how CJB varies with task manipulations designed to alter affective valence (the distance of the equipment from cover, and levels of food provisioning in the environment), and (2) assess how CJB correlates with other potential non-invasive indicators of welfare (e.g. flight distance in response to humans, QBA scores, retrapability, social status, hair cortisol concentration, and fluctuations in eye temperature following positive and negative stimuli on the judgement bias test measured using infrared thermal cameras).
Why we funded this project
As noted above, cognitive bias tests are generally considered to be exceptionally robust welfare indicators, while gray squirrels are an abundant species and a prime target for near-term interventions. Therefore, we are excited to support the development of a cognitive judgment bias test for use on free-living gray squirrels, which will also help to assess the validity of simpler indicators, such as eye temperature and flight initiation distance.
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.

Focal species: Northern elephant seal (Mirounga angustirostris), eastern Pacific harbor seal (Phoca vitulina richardii)
Conservation status: Least concern
Disciplines: Wildlife rehabilitation, animal behavior, animal welfare science
Research location: United States
Project summary
In many cases, the process of releasing a rehabilitated or translocated animal can be traumatic and removes the animal’s agency, potentially weakening their ability to thrive in the wild. 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 (distance traveled), and body condition, and the animals’ specific behavioral profiles (e.g. foraging behavior) 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.
Why we funded this project
We envision a world in which people take responsibility for improving wild animals’ lives and have the knowledge they need to do so effectively. Rehabilitation is a part of that. However, there has been relatively little research on post-release outcomes for rehabilitated animals. Understanding those outcomes and identifying strategies to improve them could have significant welfare implications, especially for the treatment of juvenile animals, whose life trajectories may be powerfully affected by the rehabilitation and release process. We appreciate that this project combines post-release monitoring with both a specific intervention and pre-release tests of affective state that would not be possible in a wild context.
Street smarts and bold behaviors: How humans and urban environments influence the welfare of wild mesocarnivores
Grantee: Lauren Stanton
Institution: University of California, Berkeley
Project summary
This project will evaluate the welfare impacts of urban landscapes and human-wildlife conflict scenarios, focusing on environmental contamination and anthropogenic disturbance by assessing how they introduce poor diet and diseases that impact wild animals’ health and behavior, potentially increasing the likelihood of further conflict. It will use motion-activated infrared trail cameras, a novel method, to noninvasively assess and compare the behavior, cognition, and health of urban wildlife in relation to differences in environmental conditions, establishing an individual-based assessment of welfare. The project will also provide a welfare vulnerability assessment in relation to environmental characteristics, which will facilitate modeling and predicting welfare risk according to environmental variables, as well as identifying mitigation opportunities for reducing poor-welfare urban environments.
Grantee: Lauren Stanton

Grant amount: $255,000
Grant type: Fellowship
Focal species: Urban canine
Conservation status: Least concern
Research location: United States
Project summary
This project will evaluate the welfare impacts of both urban landscapes and human-wildlife conflict scenarios, focusing in particular on those of environmental contamination (e.g., pollution, anticoagulant rodenticides) and anthropogenic disturbance by assessing how they introduce poor diet and diseases that impact wild animals’ health and behavior, potentially increasing the likelihood of further conflict in a vicious cycle. The project will use a novel method to noninvasively assess and compare the behavior, cognition, and health of urban wildlife in relation to differences in environmental conditions. The study will use motion-activated infrared trail cameras to observe the behavior and evaluate the health and cognition of urban wildlife. By measuring important facets of each individual’s behavior (e.g., risk-taking), cognition (e.g., problem-solving), and health (e.g., body condition), the project will establish an individual-based assessment of welfare. The project will also provide a welfare vulnerability assessment in relation to environmental characteristics, which will facilitate modeling and predicting welfare risk according to environmental variables, as well as identifying mitigation opportunities for reducing poor-welfare urban environments. In addition to improving understanding of the drivers of welfare in urban wildlife, the project will develop and demonstrate a novel approach that can be further used to understand individual welfare and, in particular, address limitations in the current ability to assess subjective experiences by validating the use of relevant cognitive indicators.

Quantifying the impact of sea ice coverage on the welfare of grey seal pups
Grantee: Daire Carroll
Institution: University of Gothenburg
Project summary
This project will use historic necropsy assessment and drone-based photogrammetry to establish and validate welfare proxies and remote behavioral and body conditions in grey seals as a remote welfare assessment tool. It will compare cortisol levels, behavior, and body condition of juvenile seals in land and ice breeding colonies at different densities to understand density-dependent welfare in relation to differences in environmental conditions. This information will be used to develop predictive models to identify welfare risk factors and opportunities to mitigate them. Opportunities to alleviate stress for juveniles during land breeding years will be identified and proposed. The project will demonstrate proof-of-concept for a combined population modeling and behavioral/health assessment approach that can be transferred to other species.

Focal species: Grey seal (Halichoerus grypus)
Conservation status: Least concern
Research location: Sweden
Project summary
This project will use historic necropsy assessment, including body condition indicators (size and blubber layer), cause of death, age, and parasite load, coupled with drone-based photogrammetry, to establish and validate welfare proxies. The project will subsequently establish and validate remote behavioral and body conditions in grey seals as a remote welfare assessment tool. The project will further seek to understand density-dependent welfare in relation to differences in environmental conditions by comparing cortisol levels from feces, behavior, and body condition of juvenile seals in land and ice breeding colonies at different seal densities. The combined information will be used to develop predictive models that can identify welfare risk factors and opportunities to mitigate them. Finally, the project will identify and propose opportunities to alleviate stress for juveniles during land breeding years to improve welfare. The project will demonstrate proof-of-concept for a combined population modeling and behavioral/health assessment approach that can be transferred to other species to understand risk factors for poor welfare and identify opportunities for correcting them.

Empirical assessment of welfare in wild American mink and Eurasian otters: the effects of intra- and inter-specific population density
Grantees: Lauren A Harrington, Maria Diez Leon
Institution: Oxford University
Project summary
This project seeks to determine whether the welfare of American mink is negatively impacted in the presence of high densities of Eurasian otters, whether both species’ welfare is compromised at relatively higher densities of conspecifics, and whether there is a seasonality to welfare impacts. The project will also assess whether behavioral time budget shifts in mink are associated with higher chronic stress levels as a proxy for negative impact on mink welfare. These questions will be addressed by measuring welfare through several different domains, including behavioral (exploratory behavior, vocalizations), physical (body condition, ectoparasite load), and physiological (telomere length, fecal glucocorticoid metabolites and hair cortisol) metrics.

Why we funded this project
This project has the potential to contribute significant information to the understanding of intra-specific density-dependent welfare and to the understanding of network effects among predator-prey and competitor interactions of wild animals. Its unusually diverse set of welfare metrics will allow for cross-validation, strengthening both this project and other projects applying the same metrics. The investigators each have a strong background in animal welfare and have made efforts to better align their work with Wild Animal Initiative’s priorities for wild animal welfare, which makes them good candidates to carry forward the validation of these welfare indicators (particularly telomere attrition, which is still relatively immature in its use as a welfare indicator).

Determination of Fecal Tri-iodothyronine and Cortisol as Physiological Proxies of Animal Welfare
Grantees: Michael Cherry, Joe Hediger
Institutions: Caesar Kleberg Wildlife Research Institute, Texas A&M University, University of Massachusetts Dartmouth
Project summary
Wild animals are susceptible to the effects of thermal stress imposed by a warming climate, including increased energetic costs to maintain a healthy body temperature, immune system impairment, changes in food availability, and increases in disease transmission. White-tailed deer in southern Texas are on the front lines of this challenge. This project aims to assess the reliability of fecal tri-iodothyronine (T3) and fecal glucocorticoids (FGC) as non-invasive physiological metrics for monitoring their health. The use of T3 as an indicator of wildlife health and welfare is relatively novel, and the researchers will attempt to refine it through controlled experiments, correlating the T3 measurements with a more widely used indicator in FGC. Both physiological indicators will be validated against behavioral observations.

Project summary
Wildlife are susceptible to both direct and indirect effects of thermal stress imposed by a warming climate. Direct effects include increased energetic costs to maintain a healthy body temperature and immune system impairment, while indirect effects include changes in food availability and increases in disease transmission. White-tailed deer (Odocoileus virginianus) in southern Texas are on the front lines of this environmental challenge. This project aims to assess the reliability of fecal tri-iodothyronine (T3) and fecal glucocorticoids (FGC) as non-invasive physiological metrics for monitoring the health of white-tailed deer. The use of T3 as an indicator of wildlife health and welfare is relatively novel, and the researchers will attempt to refine the use of these metrics through controlled experiments, correlating the T3 measurements with a more widely used indicator in FGC. Both physiological indicators will also be validated against behavioral observations of the same deer that are thought to reflect their emotional state.
Why we funded this project
The study findings will help in understanding how wild animals cope with increasing temperatures and the impact of thermal stress on their welfare and health. Notably, previous work has suggested that T3 measurements in ungulates are especially sensitive to thermal stress, and so comparing T3 with other indicators based on different physiological pathways, such as glucocorticoids, could help researchers to diagnose the relative significance of different environmental stressors an animal is facing. The project’s behavioral metrics are also crucial for realizing that potential. A secondary reason for our interest in this project is that it has near-term policy implications, potentially highlighting the value of preserving or promoting specific landscape features for the ecosystem service they offer, in the form of shade, to wild ungulates.

Characterization of fecal oxytocin and immunoglobulin A in lions (Panthera leo): Exploring a multi-biomarker approach in animal welfare research
Grantee: Paula Serres Corral
Institution: Universitat Autònoma de Barcelona
Project summary
This project will validate the measurement of oxytocin (OT) and secretory immunoglobulin A (IgA), markers of neuroendocrine and immune function, as biomarkers of wild animals’ welfare states. Both indicators have been measured in the saliva and urine of a limited set of wild mammalian species, but work on their analysis in fecal samples has been even more limited. This project will validate the measurement of OT and IgA in the feces of lions as a model for social carnivores, and evaluate their applicability as additional physiological indicators in wild animal welfare studies. The researchers will evaluate baseline levels for the species based on a small number of captive individuals and assess how these biomarkers are correlated with GCs and behavior.

Project summary
Glucocorticoids (GCs) remain the most common physiological indicators of stress and, by extension, of animal welfare. However, welfare means more than stress, and therefore there is a need to develop complementary biomarkers to expand our knowledge of animals’ overall welfare states, both positive and negative. This project will consider oxytocin (OT) and secretory immunoglobulin A (IgA), markers of neuroendocrine and immune function respectively, which have been proposed as potential indicators of positive affective states. So far, both indicators have been reliably measured in the saliva and urine of a limited set of wild mammalian species. However, previous work on their analysis in fecal samples has been even more limited. This project aims to validate the measurement of OT and IgA in feces of lions (Panthera leo) as a model for social carnivores and evaluate their applicability as additional physiological indicators in wildlife welfare studies. The researchers will evaluate baseline levels for the species based on a small number of captive individuals, and assess how these biomarkers are correlated with GCs and behavior.
Why we funded this project
With a multi-biomarker approach, these potential biomarkers, in combination with GCs, will enable a more robust interpretation of findings in welfare assessments. We are especially interested in the potential for these physiological indicators to support identification of positive welfare states in wild animals, considering the crucial role of oxytocin, for example, in social bonding. Although the project itself is limited to a small number of captive individuals, we expect that this project will represent a significant step towards validating these putative indicators of positive welfare thanks to the detailed behavioral monitoring that the captive environment allows, including a Quantitative Behavioral Assessment (QBA) approach.

Developing loop-mediated isothermal amplification (LAMP) assays for detecting pathogens in wild animal populations
Grantee: Cameron Semper
Institutions: University of Calgary, University of Lethbridge
Project summary
This project aims to develop Loop-mediated isothermal amplification (LAMP) assays for rapid, in situ detection of representative viral and bacterial pathogens, as well as parasitic worm infections in wild animals. This project will develop two methods for detecting viral and bacterial infections, respectively. The viral test will focus on viruses that have caused epidemics in wild frigatebird and sooty tern populations, while the bacterial test will focus on tick-borne illnesses and parasitic worms which infect deer mice. After developing the LAMP assays, the researchers will validate their potential contribution to monitoring wild animal welfare in a non-invasive manner by using them to test for pathogenic load in fecal samples from deer mice.

Project summary
Loop-mediated isothermal amplification (LAMP) is a low-cost technique that amplifies specific DNA to levels that can enable visual detection. LAMP has been extensively applied as a point-of-care diagnostic tool for human health, but its application in wild animal populations remains underexplored. This project aims to develop LAMP assays for rapid, in situ detection of representative viral and bacterial pathogens as well as parasitic worm infections in wild animals. This project will develop two methods for detecting viral and bacterial infections, respectively. The viral test will focus on viruses that have caused epidemics in wild frigatebird and sooty tern populations, while the bacterial test will focus on tick-borne illnesses and parasitic worms which infect deer mice. After developing the LAMP assays, the researchers will validate their potential contribution to monitoring wild animal welfare in a non-invasive manner by using them to test for pathogenic load in fecal samples from deer mice.
Why we funded this project
This research will serve as a proof-of-concept for the applicability of LAMP for monitoring infectious disease, a key determinant of wild animal welfare. Additionally, the project is specifically targeting diseases that affect a large number of animals. LAMP is simple to perform, and results can be interpreted visually without the need for sophisticated equipment, reducing the cost in time and materials for assessing disease in wild animals. Because it can be carried out in the field, follow-up treatment or further study can be immediately given to the same animal.

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.

Project summary
Steroid hormones are routinely used as biomarkers of stress and can be measured in different biological matrices, such as serum, saliva, feces, and urine. However, commonly used collection methods in wildlife are challenging; the stress they induce in the animals may affect hormone levels and also presents ethical issues. More recently, analysis of hormones accumulated in the hair has emerged as a non-invasive tool for measuring chronic stress in wildlife, but current limitations of hair analyses include variation in cortisol concentrations depending on sample preparation and the amount of hair required for cortisol extraction. 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.
Why we funded this project
Although this project is focused on development of chemical methods, we expect that the method, if validated, could make glucocorticoid assessment in the hair of wild animals much easier, increasing the future quantity and quality of that type of data. Hair is an especially interesting medium for glucocorticoid analysis because it integrates glucocorticoid levels in the body over time, causing the measurements to be more stable over time and potentially more indicative of baseline welfare, since the values are less sensitive to an animal’s most recent activities.
