Four peregrine falcon chicks have been spotted by the Hamilton Community Peregrine Project after 36 days of gestating on top of Hamilton's Sheraton Hotel.

The group has cameras watching the nest on top of the hotel in Jackson Square and captured photos this morning of the chicks hatching and meeting their mom, McKeever, who has been nesting there for around two years.

McKeever hatched four chicks last year as well, which were named Wynnstay, Balfour, Auchmar, Dundurn.

Canada currently considers peregrine falcons as a "special concern" species.

Pat Baker, a senior monitor with Hamilton Falconwatch, says the chicks will stay in and around the nest until around June.

That's when volunteers with the Hamilton Falconwatch will have volunteers on the ground watching for the chicks from 5 a.m. to 9 p.m. until they learn how to fly, she said.

"Until that time we'll be watching them online keeping an eye. They'll be banded probably in about the third week of May," she said.

Baker says special attention will be given to the male chicks, who are lighter and typically try to fly before their female siblings.

The Hamilton Naturalists Club, which runs the Peregrine Project, said in a post on Sunday morning, "A month ago we mentioned how the adults carefully timed the incubation of the first eggs so that they would all hatch together, and this has now resulted in all four eggs hatching within 24 hours!"

"With four in the nest, we will see a lot of feedings over the coming month. And needless to say, we're going to need a lot of volunteer watchers."

Interested bird enthusiasts and falcon-lovers can sign up to volunteer for the June falcon watch on the group's website.
