Natural History and Habitat Use

Black-shouldered Kite -- Elanus caeruleus
(formerly White-tailed Kite)


RANGE: Resident locally from northwestern Oregon south (west of the deserts) to Baja California, and from southern Oklahoma, western Louisiana, east-central and southeastern Texas south to South America. Strays to adjacent states, also to Florida, and in the Mississippi Valley north to Missouri and southern Illinois.

STATUS: Rare to locally fairly common; once reduced in numbers almost to the point of extinction in the United States. Year-round irrigation of agricultural land has improved habitat conditions in recent years.

HABITAT: Inhabits open country around freshwater marshes, moist meadows, alfalfa fields, and cultivated bottomlands, with scattered clumps of trees. In the western Sierra Nevada in California, found below 1,000 feet in blue oak-savannah, digger pine-oak, and riparian deciduous types.

SPECIAL HABITAT REQUIREMENTS: Trees with dense canopies for nesting near a permanent water source and an abundant population of voles (Microtus spp.).

NEST: Nests in oak, willow, eucalyptus, cottonwood, or other hardwood trees, from 18 to 59 feet above ground, usually near a marsh, streambank, or canal, and areas where voles are abundant. With good vole populations, breeding pairs need a minimum of 20 acres around the nest site for hunting.

FOOD: Searches for food by flying and hovering at less than 100 feet above ground. Feeds primarily on voles, but also eats other small mammals, small snakes, lizards, frogs, and large insects such as grasshoppers, beetles, and crickets.
