First Feed for peregrine nestlings at Montreal 

These nestlings are very young and Dad (Monsieur) brings a large prey, possibly a pigeon) for the youngsters' first feed. There are two nestings, one about 8.5 and the other just 1.5 hours old. There area also two eggs, and in one you can see the third chick trying to break out (at the time of writing, this one has since hatched).
When she, Eve, has finished, she takes the remains away and M. jumps in to incubate/brood, but she has not gone long before she returns to take her rightful place.
