It breeds from southeasternmost Arizona and Texas of the United States through Mexico and Central America to northwestern Costa Rica. This species is found in light forests, cultivation and gardens with trees. The domed nest is made of plant fibre or leaves with a side entrance. The nest is placed by a tree fork. The typical clutch is two white eggs, which are marked with rufous and lilac mostly at the larger end. Wikipedia →
