Peregrine Falcon Breeding Habits

I have had some questions on the breeding habits of the Peregrine. I gleaned this information from the World Center For Birds of Prey – The Peregrine Fund and the Idaho Department of Fish and Game. I hope this helps.

Breeding: Nests mainly in scrapes on cliff ledges … and city buildings, bridges, and other man-made structures are now favored nest sites in many parts of the world. Clutch size is 3-4 eggs in most regions, but ranges from 2-6. The eggs are creamy white, heavily suffused with markings of reddish-brown. Both parents participate in incubation, which typically lasts for 32-35 days (White et al. 2002), but most is done by the female.” (Peregrine Fund) “Males certainly do NOT hatch first. However, because they are smaller and develop quickly, they may fledge before the larger females.” (IDFG,) “Both parents feed the young, but typically the male captures prey and delivers it to the female.” (Peregrine Fund) “Most peregrines fledge at 42 – 45 days of age.” (IDFG) “The young remain dependent on the parents for up to five weeks after fledging.” (Peregrine Fund)
