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 will be adding more in the coming weeks and months.
To feed or not to feed wild birds
Grantee: Marion Chatelain
Institution: University of Innsbruck
Project summary
Despite providing otherwise limited resources, bird feeders may attract predators, facilitate the exchange of pathogens, and increase intraspecific conflict. This project will study two common bird species: great tits, who use feeders intensively, and black redstarts, who typically do not use feeders. By monitoring the use of nestboxes in gardens with or without feeders, the project aims to evaluate social stress and competition for nesting sites caused by bird feeding. Fecal samples from nestlings will also be analyzed to understand impacts on stress physiology, growth rate, and ectoparasite load.

Project summary
Bird feeding can provide birds with sustenance through challenging times, such as winter, and in places where they would not be able to find abundant natural foods, such as inner cities. However, bird feeding may also have negative consequences by aggregating birds in one location, attracting predators, facilitating the exchange of pathogens, and increasing intraspecific conflict.
This project will consider two common bird species: great tits, who use feeders intensively, and black redstarts, who typically do not use feeders. By monitoring the use of nestboxes separately targeting these two species, across private gardens that do or do not provide feeders, the project aims to evaluate social stress and competition for nesting sites caused by bird feeding. Fecal samples from nestlings will also be analyzed to understand impacts on stress physiology, growth rate, and ectoparasite load.
Why we funded this project
With the popularity of bird feeding and the density of private gardens in cities, understanding the pros and cons of bird feeding may be crucial for understanding and ultimately improving the welfare of urban birds. We especially appreciate that this project will consider both target and non-target bird species, and focuses on the welfare of juveniles.
