2011 Summary

Project Peregrine has been intensively monitoring the breeding population of Peregrine Falcons (Falco peregrinus) within the Ontario side of the Lake Superior Basin, and northwestern Ontario since 1996.

In 2011, there were 62 peregrine falcon territories identified. There were 54 territorial pairs, and 8 single birds on territory. The breeding success of the 54 territorial pairs consisted of 47 breeding pairs, of which 21 pairs were known to have fledged 52 young. The number of chicks assumed to have fledged would be significantly higher, but 23 confirmed nesting sites were not visited a second time to confirm breeding success. Eleven previous occupied sites were not surveyed in 2011. Two new territories (Agawa Canyon, Mollie Mountain) were confirmed in 2011.

Thirteen nest sites were accessed by the banding team and 31 chicks (21 males, and 10 females) were banded. Banding activities were initiated on June 18 and concluded on July 1. Sixteen of the 31 chicks that were banded had blow fly (Calliphoridae spp.) maggot infestation in their ears. This is the highest percentage of infestation that we have noted to date. A total of 501 peregrine falcon chicks have now been banded at cliff nest sites since 1996.

This year, two Reconyx motion cameras were left at two nest sites, Ouimet Canyon Provincial Park and Oliver Creek Road. The adult males at both of these sites have been identify in past years as being black banded. Photographs taken by the cameras were used to identify both males.


When the banding team is at the nest site to band the chicks, prey remains are collected from the nest ledge. Fourteen species of birds were identified from 32 prey items. New species identified in 2011 were: Brown Thrasher and Pileated Woodpecker.

Project Peregrine is indebted to the many volunteers, Pukaskwa National Park and OMNR staff who took time to survey known cliff sites, and new cliff sites for peregrine activity in 2011. With the ever increasing number of territories to monitor each year, their time and efforts are greatly appreciated. To the climbers: Frank Pianka, Leo Tardif, and Rod Swatton, who make up the banding team, a special thank you for your expertise and 261hours of donated time. Your continued interest in this project is also greatly appreciated.

Funding received by Project Peregrine to continue the monitoring and banding of peregrine falcons was provided by the Ontario Ministry of Natural Resources (OMNR) Community Fisheries/Wildlife Involvement Program, and OMNR Species at Risk Stewardship Fund./assets/files/Projects/Project_Peregrine
