Collecting detailed information on breeding parameters of cavity-nesting raptors is often difficult as the nest is usually not accessible. Nest box experiments provide detailed information about the breeding performance of these species, and helps identify population dynamics and changes in breeding phenology.

​

In areas where large-diameter trees are eliminated from the landscape due to conversion to agriculture, forestry operations, or other industrial activities, cavity-nesting species face increased competition for natural nest sites. Provision and maintenance of artificial cavities is an effective conservation measure to maintain or augment populations of cavity-nesting species.

Objectives of this Program

​

• Establish and monitor a network of at least 500 nest boxes suitable to cavity-nesting owls, and American Kestrel

• Document food composition, breeding phenology, and breeding performance of these species

• Investigate nest site fidelity and recruitment.

• Compare breeding performance of raptors nesting in predominantly forested areas in the Boreal region to those nesting in the agricultural/developed landscape of east-central Alberta

• Collaborate with individuals and organizations to build and maintain a long-term database

• Establish 50 reference plots and map all existing cavities over multiple years

• Develop site and species-specific research and monitoring projects

• Disseminate information to the public and write peer-reviewed papers

We are currently working on two projects for this program: The Genesee Bird Project, and The Breeding Ecology and Migration of the

Northern Saw-whet Owl.
