Killdeer are part of the plover family and are considered shorebirds; however, it's a shorebird that you can see without going near the water. They like to roam around in open lawns, fields and parking lots. In my rural subdivision we have large open lots that attract killdeer, so it's not uncommon to find one of their nest in a nearby flowerbed or a patch of grass this time of year.
Killdeer tend to be noisy at times with a unique call that's unforgettable once you've heard it. If disturbed, their calls can even be heard at night.
I've put together a short video clip of the female killdeer setting on her eggs.
