Peregrines: Woburn – female incubating eggs!

April 16, 2016 in Peregrine Falcon Woburn

CF2C7543-001After months of speculation among the local peregrine watchers about whether these falcon would form a pair bond; and after many weeks of observed and reported copulation activity between the unbanded male, and the not quite yet one year old banded female, it looks very much like the first eggs have been laid and the the incubation process has started.

With Peregrine Falcons, it is normal for first-time egg layers to start a bit later in the season. The eggs are laid normally about 48 hours apart, but it can be as long as 72 hours apart. Usually, full-time incubation starts after the second to last (penultimate) egg has been laid. In many nests, the female handles the incubation duties around 2/3’s of the total time with the male taking up the balance and providing the female with time off the nest.
