Peregrine falcons: 6 baby falcons have hatched on our structures this summer!

23 July 2019

Another great nesting season has just ended for the two pairs of peregrine falcons that made their nests on the Honoré Mercier Bridge and Champlain Bridge this summer.

Each couple hatched three baby falcons that started to fly in early July. Unfortunately, one fledgling had some problems during its first take-off and had to be taken to a major aviary of the Clinique des Oiseaux de proie. After getting a two-week rest, the young one will be released at the Prévost cliffs, where a couple of peregrine falcons are currently raising a baby falcon the same age.

“This practice usually works very well,” said Marie-Line Fiola, Project Manager at Falcon Environmental Services (FES). “The parents will most likely take care of the fledgling as they would their own young. It’s important that the adopted baby falcon be roughly the same age as the others in the brood, which is why the Clinique des Oiseaux de proie chose this family of falcons.”

FES has been providing falcon consultation and management services in cities for over 25 years. “We started working with FES in 2002. Together, we have implemented compensatory and mitigation measures for the birds, such as installing nesting boxes, setting up safety perimeters around our work sites during nesting periods, monitoring the birds regularly, or even intervening when necessary. This year, we innovated and set up a camera in the nesting box on the Honoré Mercier Bridge,” said Roxanne Gratton, Environmental Specialist at JCCBI.

As the deconstruction of the Champlain Bridge will start next year, two nesting boxes have been created on the Samuel De Champlain Bridge to help the falcons with their “move.” FES has noticed that one falcon has already settled into its new condo! This is a great indication that the transition for the birds is going well.

Since 2011, our infrastructure has been the site for the hatching of 40 baby falcons, although there are certainly more if we include all baby birds hatched since 2002.
