Only 2 species of Basileuterus enter the southern United States as vagrants, namely the Golden-crowned Warbler and the Ruffous-capped Warbler.
These birds are mainly robust warblers with a stout bill. The majority of species have olive or grey upperparts and yellow underparts. The head is often strikingly marked with a long broad supercilium, a coloured crown or crown stripes, and often other striking head markings.
Usually found near the ground in bushy habitats or forest understory. They build a domed nest on a bank or on the ground.
