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.
Comparative assessment of capybara (Hydrochoerus hydrochaeris) welfare in protected, semi-anthropized, and anthropized environments in Argentina
Grantee: Débora Silvia Racciatti
Institution: Universidad de Buenos Aires, Argentina
Project summary
This project will assess how different levels of human disturbance are associated with behavioral, physiological, and health-related welfare indicators in capybara (Hydrochoerus hydrochaeris). Using camera traps, direct observations, non-invasive fecal sampling, and body condition assessments, the team will evaluate a suite of indicators and test not only whether they vary in predicted directions across environments, but how consistently they converge across welfare domains, identifying which measures most reliably discriminate conditions of higher versus lower welfare in free-ranging populations.
Grantee: Débora Silvia Racciatti
Institution: Universidad de Buenos Aires, Argentina
Grant amount: $45,400
Grant type: Discovery grants
Focal species: Capybara (Hydrochoerus hydrochaeris)
Conservation status: Least concern
Disciplines: Human-wildlife conflict, physiology, animal behavior, mammalogy
Research location: Argentina
Project summary
This project compares capybara (Hydrochoerus hydrochaeris) populations living in protected, semi-anthropized, and highly anthropized environments in Argentina to assess how different levels of human disturbance are associated with behavioral, physiological, and health-related welfare indicators. Using camera traps, direct observations, non-invasive fecal sampling, and body condition assessments, the team will evaluate a suite of indicators and test not only whether they vary in predicted directions across environments, but how consistently they converge across welfare domains, identifying which measures most reliably discriminate conditions of higher versus lower welfare in free-ranging populations. By integrating validated measures into a comparative welfare assessment framework, the project aims to advance the empirical foundations of wild animal welfare science and generate evidence to inform welfare-aware wildlife management and coexistence strategies.
Why we funded this project
This project addresses a critical but underexplored question in wild animal welfare science: how anthropogenic landscape transformations affect not just population-level metrics, but also the welfare of individual wild animals. It provides a methodological proof of concept by evaluating a multi-domain suite of non-invasive behavioral, physiological, and health-related indicators that can be validated under real-world field conditions, explicitly assessing their sensitivity, directionality, and cross-domain convergence across contrasting anthropogenic contexts.
Validating behavioral, acoustic, and physiological indicators of welfare in urban birds
Grantee: Miriam Soledad Vazquez
Institution: Universidad Nacional del Sur, Argentina
Project summary
This project will evaluate whether behavioral, acoustic, and physiological indicators consistently reflect welfare-relevant experiences in two urban thrush species. Welfare will be assessed by combining focal behavioral observations (vigilance, aggression, displacement, foraging activity, and tolerance of conspecifics and heterospecifics), passive acoustic monitoring (focal activity rates and calling patterns), and feather glucocorticoid analyses across urban sites that differ in vegetation cover and human disturbance. These indicators will be interpreted together to evaluate whether they show concordant, biologically meaningful responses across urban environments, while recognizing that different indicators may capture different temporal or contextual dimensions of affective state and welfare.

Focal species: Patagonian thrush (Turdus falcklandii), Rufous-bellied thrush (T. rufiventris)
Conservation status: N/A: Multiple focal species
Disciplines: Ornithology, animal behavior, physiology
Research location: Argentina
Project summary
This project will evaluate whether behavioral, acoustic, and physiological indicators consistently reflect welfare-relevant experiences in two urban thrush species that have recently expanded their ranges into Argentine cities. Welfare will be assessed by combining focal behavioral observations (vigilance, aggression, displacement, foraging activity, and tolerance of conspecifics and heterospecifics), passive acoustic monitoring (focal activity rates and calling patterns), and feather glucocorticoid analyses across urban sites that differ in vegetation cover and human disturbance. These indicators will be interpreted together to evaluate whether they show concordant, biologically meaningful responses across urban environments, while recognizing that different indicators may capture different temporal or contextual dimensions of affective state and welfare.
Why we funded this project
The study provides a proof of concept for integrating behavioral observations, passive acoustic monitoring, and physiological measures within a multidimensional welfare assessment framework applied under natural conditions. It also addresses whether commonly proposed welfare indicators remain informative across different species and environmental contexts, including urban environments shaped by human disturbance and novel biotic interactions.
