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.
An evaluation of effective disturbance mitigation measures for European badgers (Meles meles) occupying setts during forestry operations
Grantee: Stephen McAuliffe
Institution: University of Brighton and Forest Research
Project summary
In order to avoid possible disturbance to European badgers, forestry guidance in England states that activities using heavy machinery should be prohibited within 20 meters of active badger setts. This research aims to validate that the approved noise and vibration mitigation buffer distances intended to prevent disturbance from anthropogenic activities are effective. Observations of badger behavior will be made in woodland habitats, and fecal cortisol metabolites will be collected for analysis. If changes in behavior and increases in cortisol levels are not found following exposure to forestry noise and vibration greater than 20 meters away, robust evidence will be provided to validate that badger welfare is not being adversely impacted by legally sanctioned forestry activities.
Grantee: Stephen McAuliffe
Institution: University of Brighton and Forest Research, United Kingdom
Project start date: July 2025
Grant amount: $10,137
Grant type: Seed grants
Focal species: European badger (Meles meles)
Conservation status: Least concern
Disciplines: Animal behavior, physiology, mammalogy, human-wildlife conflicet
Research locations: United Kingdom
Project summary
In order to avoid possible disturbance to European badgers (Meles meles), forestry guidance in England states that activities using heavy machinery should be prohibited within 20 meters of active badger setts. However, this commonly adopted mitigation measure has never been scientifically assessed. As a result, it relies on the untested assumption that noise and vibrations do not disturb badgers if a buffer zone of 20 meters is maintained between forestry operations and setts. This research aims to validate that the approved noise and vibration mitigation buffer distances intended to prevent disturbance from anthropogenic activities are effective. Observations of badger behavior will be made in woodland habitats, and fecal cortisol metabolites will be collected for analysis. If changes in behavior and increases in cortisol levels are not found following exposure to forestry noise and vibration greater than 20 meters away, robust evidence will be provided to validate that badger welfare is not being adversely impacted by legally sanctioned forestry activities.
Why we funded this project
This project will help us understand the welfare impacts of anthropogenic disturbance on a common mammal, and could lead to a very near-term intervention to mitigate them if the project results in a recommendation to increase buffer distances. We hope it will set a precedent for testing and improving animal welfare protection methods routinely advised and adopted by many land-based sectors such as forestry, utilities providers, construction and agriculture.
Assessment of welfare impacts of parasites and pathogens on migratory flamingos among Salt Lakes of East Africa
Grantee: Robert Modest Byamungu
Institution: Sokoine University of Agriculture
Project summary
This project will investigate the effects of parasites and pathogens on the welfare of two flamingo species ― the greater flamingo and the lesser flamingo — in the Salt Lakes of East Africa using non-invasive methods. To achieve this, the project will establish two sites: an experimental site and a control site. At both sites, it will (i) estimate parasites and pathogens loads, (ii) assess stress behaviour, (iii) quantify stress physiology and, (iv) monitor food resources of flamingos. Welfare will be assessed through behaviors (e.g., body scratching and feathers plucking), as well as signs of stress (e.g., fecal cortisol levels). The project helps provide an understanding on how environmental pressures impact wild animals' quality of life.

Focal species: Greater flamingo (Phoenicopterus roseus)
Conservation status: Least concern
Disciplines: Ornithology, animal behavior, physiology, infectious disease
Research locations: Tanzania
Project summary
This project seeks to deepen understanding of flamingo migration among the Salt Lakes of East Africa by looking at the role of parasites and pathogens on the welfare of two flamingo species ― the greater flamingo and the lesser flamingo — using non-invasive methods. To achieve this, the project will establish two sites: an experimental site and a control site. At both sites, it will (i) estimate parasites and pathogens loads, (ii) assess stress behaviour, (iii) quantify stress physiology and, (iv) monitor food resources of flamingos. Welfare will be assessed through behaviors (e.g., body scratching and feathers plucking), as well as signs of stress (e.g., fecal cortisol levels). The project helps provide an understanding on how environmental pressures impact wild animals' quality of life.
Why we funded this project
Flamingos are a highly numerous species, so the findings of this project have the potential to help researchers understand the welfare of a large number of individuals. Migration of other group-living animals may also be influenced by welfare, so the results may also be translatable to other species.
Validation of non-invasive measures for life stage in wild octopuses and AI-Assisted Behavioral Analysis
Grantee: Michaella Andrade
Institution: Federal University of ABC
Project summary
This project aims to develop non-invasive methods to assess the life stage and welfare of wild octopuses. The project will develop an AI approach that learns to recognize complex behaviors, such as body patterns and ventilation rates, in video footage. In addition, the project will develop a methodology to automatically measure the life stage of octopuses in videos and non-invasive in situ measurements of the distance between the octopuses’ eyes and eyeballs. The main goal is to correlate these metrics with different behavioral contexts to determine whether they can be used as reliable indicators of the animal’s affective state. In the long term, the project aims to create an automated tool that accelerates and improves behavioral data analysis.
Grantee: Michaella Andrade
Institution: Federal University of ABC, Brazil
Project start date: June 2025
Grant amount: $10,000
Grant type: Seed grants
Focal species: Octopuses (Octopus insularis)
Conservation status: Not evaluated
Disciplines: Animal behavior
Research locations: Brazil
Project summary
This project aims to develop non-invasive methods to assess the life stage and welfare of wild octopuses. The project will develop an innovative AI approach that automatically learns to recognize complex behaviors, such as body patterns and ventilation rates, directly from pre-recorded videos in the field. In addition, the project will develop a methodology to automatically measure the life stage of octopuses in pre-recorded videos based on our database and non-invasive in situ measurements of the distance between the octopuses’ eyes and eyeballs. The main goal is to correlate these metrics with different behavioral contexts to determine whether they can be used as reliable indicators of the animal’s affective state. In the long term, the project aims to create an automated tool that accelerates and improves behavioral data analysis, enabling large-scale studies of the welfare of wild octopuses.
Why we funded this project
This project extends a previous WAI-funded project and uses innovative approaches to analyzing behavioral data for welfare assessment.
Effect of an invasive competitor on the welfare of a threatened fish in a soft-release program
Grantee: Rafael Freire
Institutions: Charles Sturt University
Project summary
Invasive fish are common in most freshwater systems, yet their impact on the welfare of resident fish is often ignored. Invasive fish species compete and displace small-bodied native fish in several ways, including by preventing access to refuge sites, preferred foods, breeding grounds, and other important resources. This project will assess the welfare of native fish placed in sites with and without invasive competitors. Welfare will be measured using a novel population-level judgement bias test, differences in telomere attrition, and typical physical correlates of welfare in fish. In addition to revealing the impact of invasive fish on small-bodied fish welfare, this work will also promote greater consideration of the impact of animal translocation and release activities on wild animal welfare.

Focal species: Southern pygmy perch (Nannoperca australis)
Conservation status: Endangered
Disciplines: Physiology, animal behavior, ichthyology, cognition
Research locations: Australia
Project summary
Invasive fish are common in most freshwater systems, yet their impact on the welfare of resident fish is often ignored. Invasive fish species compete and displace small-bodied native fish in several ways, including by preventing access to refuge sites, preferred foods, breeding grounds, and other important resources. This project will assess the welfare of native fish placed in sites with and without invasive competitors. Welfare will be measured using a novel population-level judgement bias test developed in 2023 with prior Wild Animal Initiative support. Additional measures of welfare will include differences in telomere attrition and typical physical correlates of welfare in fish. In addition to revealing the impact of invasive fish on small-bodied fish welfare, this work will also promote greater consideration of the impact of animal translocation and release activities on wild animal welfare.
Why we funded this project
This project builds on previous work funded by WAI and has immediate potential to inform freshwater systems restoration strategies with a welfare perspective. We are also pleased to see high-quality and scalable behavioral welfare indicators being developed for fish, a group whose welfare has historically been neglected and especially challenging to study.
Between freedom and security, what makes a feral pigeon happier?
Grantee: Brandon Mak
Institution: Technical University of Munich
Project summary
Feral pigeons in Germany are subject to the Augsburg model of non-lethal population control, which involves attracting them to breed in dovecots where food and nest sites are provided, and their eggs exchanged with dummies. Others are captured and housed in aviaries under similar conditions. This project investigates the welfare implications of Germany’s non-lethal population control strategies. This is done by comparing the stress profiles of feral pigeons living “wild” in the streets, free-living pigeons breeding and feeding in dovecots, and formerly free-living pigeons translocated into aviaries. Fieldwork will be conducted to weigh pigeons (body mass measurement), collect egg and feather samples from their nests (corticosterone concentrations), and observe their behavior (locomotion and aggression).

Focal species: Feral pigeon/rock dove (Columba livia domestica)
Conservation status: Least concern
Disciplines: Ornithology, animal behavior, physiology, population ecology, wildlife management
Research locations: Germany
Project summary
Feral pigeons in Germany are subject to the Augsburg model of non-lethal population control, which involves attracting them to breed in dovecots where food and nest sites are provided, and their eggs exchanged with dummies. Others are captured and housed in aviaries under similar conditions. While aimed at reducing pigeon populations, providing food, and reducing exposure to predators, it’s possible that these measures may incidentally alleviate chronic stress in free-living individuals. This project investigates the welfare implications of Germany’s non-lethal population control strategies. This is done by comparing the stress profiles of feral pigeons living “wild” in the streets, free-living pigeons breeding and feeding in dovecots, and formerly free-living pigeons translocated into aviaries. Fieldwork will be conducted to weigh pigeons (body mass measurement), collect egg and feather samples from their nests (corticosterone concentrations), and observe their behavior (locomotion and aggression).
Why we funded this project
This project will contribute to our understanding of the potential welfare effects of (non-chemical) fertility control in pigeons, a leading candidate for near-term interventions to improve welfare in urban contexts. It will also provide some information on the validity of egg corticosterone as a non-invasive indicator of stress by measuring it alongside other more established methods (feather corticosterone, morphological and behavioural indicators) for a more robust welfare assessment.
