Male ad. (N. America). May always be distinguished by having the head and neck dull plumbeous, the crown dusky, the sides of the occiput glossed with metallic lavender-purple ; a crescent-shaped patch of white in front of the eye ; wing-coverts rich blue ; speculum green with a white bar above ; under parts pale chestnut spotted with black ; bill black ; legs and feet yellowish ; iris brown. Culmen 1.75, wing 7.2, tail 3.25, tarsus 1.25 inch. The female has the upper parts dusky varied with buffy white, the under parts dull buff, the chin and upper throat unstreaked, the rest of the head and neck streaked with dusky, the speculum dull greyish brown. In the summer the male like all its allies assumes a dress like that of the female, but retains the brighter colours on the wings.
Hab. North America generally, chiefly east of the Rocky Mountains, ranging south in winter through the whole of the West Indies and Central America to Ecuador.
In its general habits it does not appear to differ from the Garganey, and its nest and eggs resemble those of that species. It is only a very rare straggler to Europe, and has occurred once in Denmark, and at least once in Scotland.
