When doing some research for a presentation on cavity nesting birds of Northern California, I came upon a reference titled “Cavity Nesting Birds of North American Forests.” The book listed the Peregrine Falcon as a cavity nester which I thought was curious. It reads “Although the peregrine falcon is currently considered a cliff-nester, records indicate that it once nested in tree cavities. The peregrine still uses cavities in broken-off trunks in Europe, but the hole-nesting population of America apparently disappeared with the felling of the great trees on which they depended.”
My presentation consisted of several photographs of cavity nesting birds as well as videos, some mine, some from the internet. To make a long story short, I found the above video which I thought would be interesting to most birders since I had never seen or heard of Peregrine Falcon behavior like this. My audience was surprised as was I. I hope you enjoy it.
