As far as I am concerned, it is not summer without them. I love the roar of their wingfeathers rattling as they pull out of those Stuka bomber dives! It's part of their charm, I guess.
They look kinda like falcons with the long wings, but they are actually part of the bird family called goatsuckers. Back in medieval days, they thought these widemouthed birds would come in the night and nurse on your goat, causing the goat to dry up.
Also in this family are whip-poor-wills, poorwills, and such. Closely related to their ancestors is a family of birds we call owls! Howz dat for cool?
