Diagnosis: Killdeer are relatively small birds, measuring only 7.9–11 inches in length, with a 18.1–18.9 inch wingspan, and weighing approximately 2.6-4.5 ounces. Adults have a brown back and wings with a sharply contrasting white underbelly and breast. The breast has two distinctive black bands on it. The rump, conspicuous in flight, is a tawny orange. The face and cap of the head are also brown, with a white face. Eyes are black with orange eye-ring.
 

Natural History: Killdeer nest on the ground, usually in some sort of a small depression. They may or may not line the nest with grass or twigs; killdeer will use their judgment of the surrounding area and materials to best camouflage their nest. The eggs, being white yet liberally speckled with dark brown, help in camouflage. Both male and female take turns incubating the eggs until they hatch, which takes roughly 24 to 28 days. Young are precocial when they hatch; able to see and forage soon after hatching.

Behavior: Killdeer use a "broken wing" act to help lure predators away from the nest.
