It’s peregrine falcon nesting season in Gatineau Park

Please help us protect this species at risk

Gatineau Park is a natural treasure of Canada’s Capital Region and a habitat for many species at risk. As Gatineau Park biologists, my colleagues and I help ensure the protection of these species.

The peregrine falcon

The peregrine falcon, a bird of prey at the top of its food chain, is a species at risk. This raptor feeds mainly on smaller birds. It builds its nest on cliffs where it can perch. 

This majestic bird species is designated vulnerable in Quebec and of special concern in Canada. In the 1950s and 1960s, the widespread use of the pesticide DDT caused a radical decline in peregrine falcon populations.

This potent pesticide infiltrated the food consumed by falcons, and compromised its reproduction by causing it to produce thin eggshells. The population of peregrine falcons in Canada was seriously affected until the 1970s, when use of the pesticide was banned in Canada and the United States.

The return of the peregrine falcon

After surviving through many difficult years, the peregrine falcon has made a comeback. In April 2010, a Park employee and scientific researchers reported having observed a couple.

Biologist

Equipped with powerful binoculars and a telescope, student biologists working for the Park have been in the field monitoring for several weeks during the summer, in order to document the presence of peregrine falcons at their nesting site on the Eardley Escarpment

Each year since 2010, the Park’s student biologists do follow-up monitoring to update the data gathered, and ensure the effectiveness of the protection measures that are in place.

There are five active nesting sites in the Eardley Escarpment sector, and a total of five peregrine falcon couples have been observed in 2017.

Nesting season

 In Gatineau Park, the peregrine falcon’s nesting season, including the raising of its young, extends from April until August. During this period, the Park’s team of biologists focus particularly on the protection of this species, which is very sensitive to human interference.

Human presence can disturb a peregrine falcon couple, which, when agitated, could cause the eggs to fall out of the nest before the chicks have hatched. Frightened chicks may try to fly too soon and die as a result of falling. Repeated disturbances can cause the couple to abandon the nesting site to which peregrine falcons usually return year after year.

Protection measures

The NCC has established measures to protect peregrine falcon nesting sites in Gatineau Park, because of the fragility of these important habitats. These measures are similar to numerous other measures established to protect other natural environments.

Some sectors of the Eardley Escarpment are closed during the nesting season. Please check the maps below for specific details. Signage panels have also been installed.

Thank you for your cooperation in complying with the closure period for these sectors and for some unofficial trails. We hope that you will take this opportunity to discover other trails in the Park.

Canada’s Capital Region is very fortunate to have such a treasure as Gatineau Park, and especially because it provides a habitat for such an interesting species at risk as the peregrine falcon.
