Outside the breeding season during the winter, they roost communally in groups of up to 100. They rarely if ever eat other birds, and even in open cerrado, mixed-species feeding flocks will generally ignore them. White-tailed kites feed principally on rodents (as well as small opossums, shrews, reptiles, amphibians and large insects), and they are readily seen patrolling or hovering over lowland scrub or grassland. At different times, two had been sighted in New England as of 2010. On rare occasions the bird can be found far outside its usual range.
Globally, they are not considered threatened species by the IUCN. They are also found from southern Texas and eastern Mexico to the Baja California Peninsula and through Central and South America to central Argentina and Chile. Elsewhere in California, they are still rare or absent. They can be found in the Central Valley and southern coastal areas, open land around Goleta including the Ellwood Mesa Open Space, marshes in Humboldt County, and also around the San Francisco Bay. The white-tailed kite was rendered almost extinct in California in the 1930s and 1940s due to shooting and egg-collecting, but they are now common again. Both the wings and tail are relatively elongated, and the tarsus measures around 3.6 cm (1.4 in). Mainly white underneath, it has black wingtips and shoulders. The coloration of the white-tailed kite is gull-like, but its shape and flight is falcon-like, with a rounded tail. caeruleus but is now regarded as separate again. caeruleus is once again called black-winged kite, while the name black-shouldered kite is now reserved for an Australian species, Elanus axillaris, which had also been lumped into E. This argument was accepted by the American Ornithologists' Union, so the white-tailed kite was returned to its original name.

More recently it was argued that the white-tailed kite differed from the Old World species in size, shape, plumage, and behavior, and that these differences were sufficient to warrant full species status. įor some recent decades, it was lumped with the black-winged kite of Europe and Africa as Elanus caeruleus and was collectively called black-shouldered kite. The specific epithet leucurus is from the Ancient Greek leukouros for "white-tailed": leukos is "white" and oura is "tail". The word Elanus is from Ancient Greek elanos for a "kite". It is now one of four species in the genus Elanus which was introduced in 1809 by the French zoologist Jules-César Savigny.
The white-tailed kite was described in 1818 by the French ornithologist Louis Jean Pierre Vieillot under the binomial name Milvus leucurus with the type locality as Paraguay. It replaces the related Old World black-winged kite in its native range. The white-tailed kite ( Elanus leucurus) is a small raptor found in western North America and parts of South America.
