Satellite telemetry, detailed monitoring of active nests, and a review of archived nesting data since the resumption of breeding in east North America were used to characterize aspects of the ecology of this rebuilding population.
The accuracy of small satellite transmitters was confirmed to be appropriate for tracking long-distance movements, and they were used to compare the dispersal and migration of 34 Peregrine Falcons.
In Ontario, the Peregrine Falcon population has grown to a record size, initially due to an intense captive-breeding and release effort, and more recently to considerable immigration from adjacent states. This influx resulted in a substantial dilution of the original F.p. anatum gene pool, in part because anatum juveniles appear to have been recruited to the breeding population at a lower rate.
Pooling data from southern Ontario, Quebec, Massachusetts, Pennsylvania, and New Jersey revealed that productivity varied considerably by region, but overall was similar at urban and rural sites. Within urban habitat, productivity was greater on buildings than on bridges and highest in nest boxes on covered ledges. While building and vehicle collisions account for significant mortality among urban juveniles, human assistance through provision of nest boxes and rescues of grounded fledglings may offset these risks.

This thesis summarizes MRF research on Short-eared Owls from 2008 through 2010, largely in eastern Ontario. It begins with an introductory chapter that reviews the natural history of Short-eared Owls and describes population declines in North America. The main chapters address 1) using stable isotope analysis to investigate spatial origins of Short-eared Owls, 2) using repeated evening surveys to assess occupancy, detectability, and habitat use across seasons, and 3) documenting nest-site characteristics, success, and threats facing the eastern Ontario population.
