Killdeer get their name from one of their most common calls, a shrill, wailing “kill-deer”. They are shorebirds that nest away from water. Like most (all?) plovers, they lay their eggs in a shallow scrape in somewhat exposed areas, even on gravel rooftops. They will deploy a broken-wing display to lead predators away from their nests. However, this doesn’t stop horses or cows from stepping on their eggs. To deter these large hoofed animals, a killdeer will try an “ungulate display”, fluffing itself up, splaying its tail over its head, and running at the beast to attempt to make it change its path. Sadly, this tactic is often fatal for the bird.
