In North America the Peregrine Falcon (Falco peregrinus) was called “Duck Hawk” when I was a child, the name changed to the more accurate Peregrine Falcon in 1957. Because it has a worldwide distribution it has many subspecies and I have shown F. p. anatum, the one that is found across most of Canada but was nearly lost to the negative effects of DDT. Because captive breeding and release programs to restore the species in the U.S. involved other subspecies, it could be that “pure” anatum Peregrine Falcons are no longer to be found, so I used as my reference a specimen obtained in the 1930s, before DDT even entered the landscape. They eat a variety of prey, not just ducks, and in urban environments often survive mostly on non-native pigeons, but I have depicted a bird in the high arctic having just captured a Harlequin Duck (Histrionicus histrionicus). I’ve shown a male falcon, the females being distinctly larger. The figures are approximately life size.
