Current research and/or projects
Conservation and management of declining landbird populations with emphasis on grassland and aerial insectivore species
- Studying the demography and population dynamics of grassland birds in the prairies
- Studying the effects of agricultural practices on grassland birds to support development of Beneficial Management Practices
- Supporting Environment and Climate Change Canada's exploration of the causes of population decline in aerial insectivore birds
- Supporting recovery of Species At Risk through research on causes of popualtion declines and conservation practices
