Like the Dickcissel, Killdeer are named because of their call. And a loud, clear Killdeer call it is. You’ll know right away when there are Killdeer around, and you’ll know when you are getting close to a nest because the calls become louder and more intense. I never did see a nest on this day, or babies for that matter, so I wonder what they were so upset about. Probably nothing, just wanted their pictures taken, and all the fame and glory that goes along with making it on birds of the bog.com.
