These three species were until recently considered one species which was then called Black-shouldered Kite (Elanus caeruleus).

Two subspecies recognised[1]:

  • E. l. majusculus:

Open woodland and grasslands with scattered trees, often near rivers and lakes.

Behaviour

Outside the breeding season they roost communally in groups of up to 100.

Diet

The diet consists mostly of rodents such as mice and voles, with the addition of other small mammals; they will also occasionally hunt birds, reptiles, and amphibians.

They construct a platform from sticks and place it in the fork of a tree or bush. The clutch consists of 3-5 eggs which are incubated for 30 - 32 days. The young fledge at 5 - 6 weeks.
