Habitat

This species is found in marshy savannahs, reedbeds and the edges of mangrove swamps. White-headed Marsh Tyrants wait on an exposed low perch in marsh vegetation or a branch near water, occasionally sallying out to feed on insects, their staple diet, before returning to the perch. They often pick off insects from the vegetation, but more frequently out of mid-air and even from shallow water.

Reproduction

The nest is a feather-lined oval ball of grasses and other plant material, with a porched side entrance. It is placed at the end of a branch near or over water. Both sexes incubate the typical clutch of two or three creamy-white eggs, which are marked with a few brown spots. Cowbirds often parasitise the nest.
