The genus name Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek kharadrios a bird found in ravines and river valleys (kharadra, "ravine"). The specific semipalmatus is Latin and comes from semi, "half" and palma, "palm". Like the English name, this refers to its only partly webbed feet.[2] DescriptionThis species weighs {{convert|22|-|63|g|oz|abbr=on}} and measures {{convert|14|-|20|cm|in|abbr=on}} in length and {{convert|35|-|56|cm|in|abbr=on}} across the wings.[3] Adults have a grey-brown back and wings, a white belly, and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes and a short orange and black bill. HabitatTheir breeding habitat is open ground on beaches or flats across northern Canada and Alaska. They nest on the ground in an open area with little or no plant growth. They are migratory and winter in coastal areas of the southern United States, the Caribbean and much of South America. They are extremely rare vagrants to western Europe, and have been found in Tierra del Fuego and the Isles of Scilly.[4] Their true status may be obscured by the difficulty in identifying them from the very similar ringed plover of Eurasia, of which it was formerly considered a subspecies. BehaviorSemipalmated plovers forage for food on beaches, tidal flats and fields, usually by sight. They eat insects, crustaceans and worms. This bird resembles the killdeer but is much smaller and has only one band.[5] Since the semipalmated plover nests on the ground, it uses a "broken-wing" display to lure intruders away from the nest, in a display similar to the related killdeer.[6] Gallery==References== 1. ^{{IUCN|id=22693764 |title=Charadrius semipalmatus |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} 2. ^{{cite book | last= Jobling | first= James A | year= 2010| title= The Helm Dictionary of Scientific Bird Names | publisher=Christopher Helm | location = London | isbn = 978-1-4081-2501-4 | pages=99, 353}} 3. ^CRC Handbook of Avian Body Masses by John B.
