Killdeer (Charadrius vociferous)

About the Bird

Seen/Heard at
Decorah, Decorah North

Diet
Killdeer are ground foragers. They feed primarily on invertebrates year-round, including earthworms, snails, crayfish, grasshoppers, beetles, caterpillars, spiders, centipedes, fly larvae and aquatic insect larvae, although they will eat seeds. Cornell mentions that Killdeer have been seen eating dead minnows and hunting frogs.

Nesting
Killdeer breed from early March through mid-August, depending on location. Males commonly begin creating a shallow depression or scrape in the ground. Once he is joined by a female, both work on the nest, adding rocks, bits of shell, sticks, and trash to the nest after egg-laying begins. Killdeer lay four to six dull tan to yellow-gray eggs per clutch and may produce up to three broods per year. Males and females incubate for 22-28 days and young leave the nest immediately after hatching. Killdeer lead their young to feeding areas, but are not known to feed their young.
