DNA testing is revolutionizing our understanding of the relatedness between different species. Among the avifauna, one of the surprises has been the discovery that falcons are close relatives of parrots and share a common ancestry with songbirds. This is one of the reasons you will find falcons next to parrots in your printed bird guide (at least if it’s of recent vintage), instead of next to hawks, those other diurnal birds of prey whom they resemble most.
Falcons tend to be smaller than hawks, have more slender and pointed wings, and more rounded faces. They are swift predators that mostly capture their prey on the wing. Sadly, their diet consists mainly of other birds. They reach impressive velocities, with the Peregrine Falcon able to plummet out of the sky at speeds of up to 200 mph.
Of the nearly 40 global falcon species, and the 7 that occur in North America, I’m still hoping to make the acquaintance of a Crested Caracara, Gyrfalcon, and Aplomado Falcon in the wild (I have seen one of the latter as a captive bird). The 4 species I enjoy semi-regularly in Colorado are the American Kestrel, Merlin, Peregrine Falcon, and Prairie Falcon. I hope you will, too.
