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.

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.

Focal species: House sparrow (Passer domesticus)

 

Conservation status: Least concern

Disciplines: Animal welfare science, ornithology, population ecology, animal behavior

 

Research location: United Kingdom


Project summary

Vocalisations carry emotional, physiological, and individual information, suggesting that they can serve as potentially useful non-invasive indicators for inferring wild animal welfare. Communication of affective states via vocalization is due to changes in emotions leading to deviations in the nervous system, causing physiological changes within the vocal production systems. Modern sound analysis techniques have provided tools to discriminate, analyze, and classify specific vocalizations, permitting them to be used for monitoring welfare of different farm and laboratory animals. However, this approach lacks validation for wild individuals. This proposal aims to use passive acoustic monitoring to record wild bird calls at different locations in urban, rural, and conservation-managed areas in the UK. This project will follow a comparative approach to identify vocal patterns and chorus characteristics related to different environmental risks (starvation risk, predation risk, human disturbance, etc.) so that these vocal signatures can be used to infer the welfare status of local bird populations across different environments. The focal species will be one of Europe’s most common species, the house sparrow (Passer domesticus). House sparrows provide an ideal first validation as the species has undergone a massive population decline in many parts of its range over the past 50 years, suggesting that its local populations are facing significant welfare challenges. Validating acoustic monitoring as a tool for non-invasive welfare monitoring in the wild for the first time will provide the basis for future application to birds in general, providing a method that could be used to monitor welfare and changes in welfare of wild birds at any location globally.

Project objectives

Objective 1: Evaluate how changes in sparrow welfare driven by changes in risk of starvation can be indicated by changes in the vocal signatures of local populations.

Objective 2: Understand relationship between predation risk driven changes in sparrows’ welfare and the vocal signatures of local populations.

Objective 3: Impact of human disturbance on sparrows’ welfare.

Why we funded this project

This project is very similar to projects by Claudia Wascher and Sam Reynolds. As stated, bioacoustic monitoring is an extremely promising approach because it is minimally invasive and inexpensive. However, it still needs to be validated, and given its potential future value, we felt that it would be best for it to be validated by at least two independent studies. This project was especially appealing because it focuses on such a ubiquitous species (the house sparrow) and is led by a researcher with a strong record in bioacoustics and an understanding of animal welfare science.

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.

Focal species: Red-billed chough (Pyrrhocorax pyrrhocorax)

 

Conservation status: Least concern

Disciplines: Animal welfare science, ornithology, population ecology, animal behavior

 

Research location: United Kingdom


Project summary

In principle, animal vocalizations can be used to identify both positive and negative experiences. Specific vocal characteristics (e.g., mean fundamental frequency) and the rate of occurrence of certain call types can help to quantify animal welfare and are well-established in farm animals such as pigs, horses, cows, and chickens. But although bioacoustic monitoring is a well-established method in captive animals, the method has not been used in wild animals to assess positive and negative emotional states. 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, monitoring activity during the night with night vision scopes, and “active” acoustic monitoring using 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. 

Why we funded this project

This project will help to validate the use of passive acoustic monitoring to assess welfare states from variation in vocal behavior, which presents a non-invasive, cost-effective tool to assess the impact of positive and negative events on animal welfare. In theory, acoustic monitoring could be used to assess the welfare of a large number of individuals at a time, making it a particularly promising method to investigate.

Impacts of land-use on social networks in mixed-species bird flocks, with implications for the short-term and long-term welfare of Himalayan birds

Grantee: Akshay Bharadwaj

Institution: Indian Institute of Science

Project summary

This project will use mist-netting and bird-banding, followed by standardized observations of behavior and body condition, to examine the relationship between individual-level social behavior, bird health, and survival within mixed-species bird flocks (MSFs) in Eaglenest Wildlife Sanctuary, Arunachal Pradesh, India. Feather corticosterone level, ectoparasite load, and other morphological parameters will be used to measure the health of each banded individual. The researcher will also take advantage of a long-term bird-banding dataset, spanning 12 years, to examine the linkages between inter-individual differences in social behavior and the survival of each individual, comparing survival rates and reproductive success in primary and logged forest.

Why we funded this project

Understanding the importance of multi-species flocking behavior in birds is relevant to our research priority of understanding indirect welfare effects in ecological systems, which this project approaches in a cost-effective way. We were especially impressed by the quality of the proposal for this project, particularly as it is led by a beginning graduate student in India. Funding this project serves to increase the geographic diversity of our grantee community and therefore of the nascent field of wild animal welfare research.

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.

Grant amount: $19,200

 

Grant type: Small grants

Focal species: Great tits (Parus major)

 

Conservation status: Least concern

Disciplines: Animal behavior, animal welfare science, physiology

 

Research location: Germany


Project summary

Breath rate (BR) is increasingly used as a non-invasive proxy of stress that is fast, cheap, and field-friendly. However, BR has not been evaluated in a bird welfare context, and it is unclear how it relates to established physiological proxies of stress, like glucocorticoid measurements in blood. Also, the currently used protocols to measure BR lack standardization, scalability, and validation. This project aims to provide a validated, non-invasive reference tool for standardizing BR measurements following capture and physical sampling protocols in wild birds by implementing computer vision capabilities and other improvements in software the researchers have recently developed to estimate BR metrics from mobile phone videos. This will allow the research community to gather objective, reproducible, and comparable data, and provide 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 (Parus major), a songbird extensively used in wild animal research across Europe, by analyzing an existing, five-year dataset to test whether BR corresponds to simultaneous glucocorticoid measurements from free-living great tits. These data will provide reliable baselines and ranges for glucocorticoids and BR, and benchmarks for video recording lengths. 

Why we funded this project

We are generally interested in developing non-invasive ways of measuring indicators of wild animal welfare. One of the key advantages to non-invasive measurement, besides the obvious of not causing unnecessary fear or pain to animals, is that stress induced by the measurement process can obscure the animal’s baseline stress levels if the method is too invasive or not carried out properly. We also tentatively believe that instilling a norm of minimizing animal harm within welfare biology research will increase the likelihood that researchers act as scientist-advocates for implementation of wild animal welfare interventions. This project’s focus on making breath rate easy and inexpensive to measure in a consistent way also fits well with our desire for a greater volume and accessibility of welfare data collection.

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.

Research location: Malawi


Project summary

Lilongwe City (the capital of Malawi, central Africa) has a good network of green spaces and river corridors, supporting a population of urban spotted hyena (Crocuta crocuta). However, human-wildlife conflict (HWC) is frequent, often resulting in persecution of these animals. Using non-invasive techniques, this project will measure and compare the fecal and hair cortisol levels (as a proxy of stress), mean body condition, tooth ware, hematological parameters, and disease (toxoplasmosis and rabies) in spotted hyena between urban (Lilongwe district) and rural (Kasungu National Park) populations. 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.

Why we funded this project

Interactions between people and wildlife are increasing as urban areas expand. This is of particular concern with carnivores, as even small species can be perceived as threatening. Despite the fact that the developing world has the highest rate of urbanization, urban carnivore studies have generally focused on European and Asian cities, with research on African cities being relatively neglected. Although HWC is a traditional issue in conservation, we have encountered few projects that effectively address the more neglected question of how HWC interacts with non-anthropogenic welfare impacts. By considering a variety of welfare indicators/factors, including disease transmission and social dynamics, this project will help us understand that interaction, producing results that can be translated into more abundant urban species. Additionally, by funding at least some projects on endangered species, we increase the likelihood of our welfare-focused message reaching conservation practitioners, potentially leading to a greater emphasis on and interest in welfare within that community.

From rehabilitation centers to the wild: Evaluating brown bear stress using blood and scat parameters

Grantee: Morteza Naderi

Institution: Koç University

Project summary

Brown bears play a prominent role in the ecosystems of northern and eastern Turkey. However, there are serious long-term threats to their welfare and viability that are common to other large omnivores, such as habitat fragmentation and increasing contact with humans. For example, open garbage dumps are located across the bear’s distribution and affect behavioral patterns in bears, including seasonal migration habits, whereby the bears would normally move into different areas to exploit seasonal resources. This project will involve a collaboration with KuzeyDoga, one of the only nature conservation NGOs in Turkey, to monitor the behavior and stress physiology of individual free-living bears using GPS collars, camera traps, and blood and fecal glucocorticoids (GCs).

Project summary

Brown bears play a prominent role in the ecosystems of northern and eastern Turkey. However, there are serious long-term threats to their welfare and viability that are common to other large omnivores, such as habitat fragmentation and increasing contact with humans. For example, open garbage dumps are located across the bear’s distribution and affect behavioral patterns in bears, including seasonal migration habits, whereby the bears would normally move into different areas to exploit seasonal resources. This project will involve a collaboration with KuzeyDoga, one of the only nature conservation NGOs in Turkey, to monitor the behavior and stress physiology of individual free-living bears using GPS collars, camera traps, and blood and fecal glucocorticoids (GCs). The location and behavior data will allow them to document what stimuli individual bears have been exposed to (e.g. use of garbage dumps, proximity to roads), and when. This information can then be paired with the GC results to better understand the welfare implications of those exposures. The study of wild bears will also be complemented by the same physiological measurements on bears residing at a rehabilitation center in the region, which come from a similar genetic and early-life background to the free-living bears.

Why we funded this project

This project addresses our objective of validating non-invasive physiological welfare indicators (e.g. fecal GCs) against behavior and known environmental stressors. The pairing of wild and captive (rescued/rehabilitated) individuals is also notable because the captive individuals can serve as a sort of control group due to their controlled environment at the rehabilitation center. Although brown bears in Turkey are not as numerous as some other species we tend to prioritize research on, they and the threats they face are ecologically similar to those faced by most bears worldwide, especially North American black bears, who number many hundreds of thousands. Therefore, we expect the findings of this project to be at least partially generalizable to more than one million potentially long-lived individuals.

WellSeal: Non-invasive quantification of welfare in lactating harbour seals

Grantee: Jess Harvey-Carroll

Institution: University of Gothenburg

Project summary

Limited availability of harbor seal birthing sites leads to intraspecific competition, forcing mothers to choose when and for how long to forage, and resulting in trade-offs between maternal and offspring welfare. These trade-offs may be exacerbated by fishing, as harbor seals swim large distances to obtain food. This project will use camera trap footage and 3D modeling to assess the influence of maternal welfare on time spent away from pups, and pup welfare during periods of maternal absence. Welfare will be assessed based on body condition, an index of the optimality of haul-out position, and a record of positive and negative interactions. The assessment will be aggregated at colony level to compare welfare between colonies with varying access to food.

Grantee: Jess Harvey-Carroll

 

Institution: University of Gothenburg, Sweden

Grant amount: $30,000

 

Grant type: Small grants

Focal species: Harbour seal (Phoca vitulina)

 

Conservation status: Least concern

Disciplines: Population ecology, animal behavior, animal welfare science

 

Research location: Sweden


Project summary

Harbor seals require locations protected from adverse weather and other disturbances during the birthing season, when vulnerable pups are left on land while mothers forage. The limited availability of such sites leads to high intraspecific competition, in which larger seals are likely to dominate more desirable locations due both to their physical strength and their lower need to forage. Mothers must choose when and for how long to forage, leading to trade-offs between maternal and offspring welfare which may lay the foundation for the welfare of younger generations. Currently, little information is available on time spent foraging during the lactation period. As harbor seals are facing unprecedented stress from overfishing, seals are swimming increasingly large distances to obtain food. It is not known how this change affects the trade-off between maternal foraging and offspring care, and the resulting welfare of the pups. This project will use camera trap footage and state-of-the-art 3D modeling to non-invasively assess the influence of maternal welfare on the time spent away from the pups. Pup welfare during periods of maternal absence will also be assessed. Welfare will be assessed in terms of the Five Domains framework, based on individual body condition (health), an index of the optimality of their haul-out position (environment), and a record of positive and negative interactions (behavior). Such welfare assessment will be aggregated at a colony level to compare welfare between colonies with more and less access to food.

Why we funded this project

We funded this project because it seeks to evaluate welfare impacts of population density — likely a common cause of welfare issues — in a relatively abundant species, using a robust approach that is only possible thanks to the species-specific knowledge of the PI and her collaborators. For example, we value their use of image analyses to identify haul-out site suitability and welfare impacts on a fine spatial scale that takes into account both environmental and social factors. We also valued the focus on juvenile welfare and the conflict of interest that may arise between parent and offspring. Improving our understanding of the fundamental relationships between population density, parental care, and juvenile welfare will allow the results of this project to extend to other contexts.

Developing a consensus profile of wild animal welfare: integrating non-invasive monitoring of the gut microbiome with stress physiology and behavior

Grantee: Sam Sonnega

Institution: University of Massachusetts Dartmouth

Project summary

This project will characterize the gut microbiome of white-footed mice and investigate its relationship with their stress physiology and behavior. Mice will be trapped and fecal samples collected to measure glucocorticoid concentrations and gut microbiome composition. Concurrently, open-field trials will be conducted to assess individual variation in cognitive bias. Perception of predation risk will also be experimentally manipulated by exposing mice to playbacks of predator noises. By correlating the gut microbiome with behavioral and endocrine metrics, a consensus profile of the mice’s welfare will be developed that reflects the complexity of their responses to environmental perturbations, and how those responses can scale up to population and ecosystem level changes via the demographic effects of stress in a “landscape of fear.”

Project summary

This project will characterize the gut microbiome of wild white-footed mice (Peromyscus leucopus) and investigate its relationship with their stress physiology and behavior, including how it changes in response to ecological pressures. While a growing literature from lab-based studies has demonstrated the link between the gut microbiome and regulation of host physiology and behavior, the generality of these findings in ecological contexts remains largely untested. As part of this project, mice will be trapped during different seasons and fecal samples will be collected from which to measure both glucocorticoid concentrations and gut microbiome composition. Concurrently, open-field trials will be conducted to assess individual variation in cognitive bias towards optimism or pessimism (a well-established behavioral indicator of affective state). The mice’s perception of predation risk will also be experimentally manipulated by exposing free-living mice to playbacks of predator noises. By correlating the gut microbiome with both behavioral and endocrine metrics, a consensus profile of the mice’s welfare will be developed that reflects the complexity of their responses to both predictable and unpredictable environmental perturbations, and how those responses can scale up to population and ecosystem level changes via the demographic effects of stress in a so-called “landscape of fear.”

Why we funded this project

We are interested in the development and validation of the gut microbiome as a welfare indicator. Every additional indicator strengthens the interpretation of others, but understanding the gut microbiome may be especially important because it is part of the causal chain linking what is going on in the animal’s brain to fecal metabolites, which are often analyzed as a non-invasive and time-integrated record of physiological stress. This project also links and builds on other gut microbiome research we have funded (by Melissa Bateson, Pablo Capilla-Lasheras, and Davide Dominoni).

Assessing the Welfare of Wild Olive Baboons (Papio anubis) at the Uaso Ngiro Baboon Project, Laikipia, Kenya

Grantee: Monica Wakefield

Institution: Northern Kentucky University and Iowa State University

Project summary

This project aims to assess the welfare of wild baboons using a holistic approach. The study takes advantage of almost 40 years of long-term ecological, demographic, health, and behavioral information on >170 individually known baboons, and will examine how various factors such as age, sex, and social rank correlate with individual welfare measures such as incidence of injury and disease, body mass, and pro-social or agonistic behaviors. The annual scale of the dataset will also enable the researchers to test how events such as droughts have affected welfare during specific periods, and how these effects may have varied according to individual animals’ demographic profiles and biographies.

Why we funded this project

We are excited by this project’s analysis of a long-term longitudinal dataset because of the importance of understanding how wild animals’ welfare varies with demographic factors such as age and sex, as these groups often face different challenges and have different ecological and behavioral requirements, and negative welfare impacts that fall on young individuals may also have ripple effects throughout their lives. We also appreciate this project’s holistic approach. The long-term monitoring means it is possible to consider not only the usual downstream welfare indicators based on health and behavior, but also upstream factors that might influence them, such as social interactions and exposure to predators.

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.

Conservation status: Least concern

Disciplines: Animal behavior, population ecology, community ecology

 

Research location: United Kingdom, South Africa


Project summary

Fierce group conflicts are not uniquely human, and many group-living animals regularly engage in “animal warfare.” These inter-group interactions play an influential role in natural population regulation, yet the health and well-being consequences for those involved remain unclear. Conservation and management interventions are currently developed with little understanding of how large-scale conflict affects welfare in wild animals. Given that anthropogenic habitat loss and climate change could increase the frequency of inter-group battles, there is an urgent need to investigate the welfare cost of animal warfare. This research program will investigate the welfare consequences of intergroup interactions and fights in wild Kalahari meerkats (Suricata suricatta). The project will take advantage of 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.

Why we funded this project

This project addresses a neglected topic related to our research priority of understanding conflicts of interest between wild animal groups. We especially appreciate this project’s holistic approach to welfare assessment, its attention to indirect effects (collateral damage) of animal conflicts in the form of costs to orphaned juveniles and the creation of a “landscape of fear,” and the openness of the investigators to considering interventions that could elevate wild animal welfare above its natural baseline.
