Project Nestwatch

Project NestWatch is a long-term monitoring program of breeding birds and nesting activity in Canada. Data gathered through this project provide valuable information on the health of bird populations and changes in the environment.

Thousands of scientists and Citizen Science volunteers from across the country monitor, record and submit nest observations each year. These efforts contribute important information for understanding, research and conservation of wild birds and their habitats. Using Project NestWatch data, we can:


    • Document distributions of breeding birds in Canada.
    • Monitor bird health and changes to breeding populations.
    • Evaluate impacts of changes in the landscape and long-term climate patterns.
    • Better understand the timing of nesting across Canada.
