Killdeer

Killdeer, Charadrius vociferus is a species of plover in the Charadriinae subfamily. It is closely related to the Common Ringed Plover. There are three subspecies.

Taxonomy
The Killdeer is closely related to the Common Ringed Plover.

Description
The Killdeer is a large plover, at 9 - 11 in. It is distinctively marked with two breast bands,   undefined young only have one band. Sexes similar, but female tends to have browner mask and breast bands.

Fairly long black tail, with a buffy-orange rump. The bill black and legs are flesh-coloured. The forehead, eye-stripe, collar on hindneck and underparts white. In flight, it shows a tawny rump.

Non-breeding adult has rufous and buffish brown fringes to upperparts. Juveniles are like dull non-breeding adults.

Race ternominatus smaller, paler and greyer; peruvianus also smaller than nominate, and has more extensive rufous feather fringes.

Similar species
It is larger than the other ringed plovers, and easily distinguished by its two black bands.

Similar to Semipalmated Plover, but is larger and white below. A downy young Killdeer has one breast band and might be identified as a Wilson's Plovers by overeager birders.

Behaviour
Generally found in as scattered individuals or small groups. Seldom found in large flocks, but sometimes up to fifty. It is stable and has adapted well to human encroachment.

Diet
Insects, mainly beetles and flies, also grasshoppers, crickets, caterpillars, dragonflies, etc.; millipedes, worms, snails, spiders, crustaceans and some seeds.

Calls
The Killdeer is quite vocal. Calls include several strident nasal piping notes, such as “deee”, “tyeeee” or “kil-deee” (hence its name), repeated. When it's agitated, several notes given in more rapid sequence such as “keee-di-di-di” or longer trilled series. In its display flight, a continuously repeated similar-sounding “kil-deer” or “kee-deeyu”. In alarm utters a long fast trill, “trrrrrrrrr”.

Reproduction
May feign injury near its nest to distract intruders, or fly into the faces of livestock.
