While the females are much drabber by comparison, their gold/tan color and black spotting makes them stand out from other species as well. Partners in Flight estimates that the global breeding population is around 50 million; 30% of which can be found in North America and Canada. In Hawaii, they are found as high as 11,000 feet !

Two-thirds of the world’s population breeds colonially on Greek islands. Unlike other falcons, they do not breed in spring, but in late summer, to exploit the abundance of songbirds and pick up those first-time (and last-time) migrants from the sky.
