4 EGGS AT THE HONORÉ MERCIER BRIDGE!

April, 12, 2021

Our peregrine falcon pair are back at the Honoré Mercier Bridge in the same nest as last year. They are expanding their family and the female is now incubating four eggs!

The falcons generally nest on cliffs, and the piers of the Honoré Mercier Bridge are very similar to their natural habitat. That’s why we installed nests almost 30 metres high up to help them feel at home in our environment. 

Watch the arrival of the first egg this year live!

We’ve had nesting boxes on our structures for over ten years. The team responsible for maintaining the structure has been advised to comply with our environmental policies in the presence of a bird of prey.

The camera also provides data on the falcons’ nesting periods. Falcon Environmental Services (FES) then collects this data to understand the birds’ behaviour. FES has observed that the egg-laying period starts at the end of March. Baby falcons stay in the nest for about 35 to 42 days. After the fledglings’ first flight, they remain dependent on the nest for at least 30 days. Young falcons only leave the nest for good at the end of August.  

Based on these observations, we have set up work restriction zones of between 100 and 200 metres away from the nests, depending on the month, so that we don’t disturb the baby falcons’ development. 

Since 2011, 34 perfectly healthy baby falcons have hatched on our structures.
