Today I had the
privilege misfortune I really don’t know what tof observing killdeer courtship.
Basically, the male killdeer starts to scrape out a nest. He does this by lowering his chest to the ground (this is on a patch of gravel, mind you), sticking his tail in the air, and spinning in a circle while waggling said tail and chirping softly. Then he stands up, flares out his tail, and backs towards the female. If she’s impressed she’ll take a turn scraping out the nest site. In this case, she wasn’t; the site was right in the middle of a driveway, so I’m glad at least one featherbrain had a bit of common sense.
