Farutso Forest, Gambia, March 201

Open grassland and shrubby areas, including open woodland, scrub, gardens and cultivation.

Behaviour

Diet

The diet consists mostly of small seeds which are gleaned from the ground. They also catch insects in flight.

The female may eat the eggs of the host species.

Breeding

They are a brood parasite laying their eggs in the nests of estrildid finches, especially waxbills. In South Africa, the primary host is Common Waxbill Estrilda astrild.

In Puerto Rico, only introduced species are parasitized, none of the native species. Their 2-4 white eggs are added to those already present in the nest.
