They measure 15 cm and weigh 16 to 19 g. The plumage of the forehead, throat and upper breast is coloured deep rufous-chestnut. The crown and upperparts are a shiny steel-blue. Flight and tail feathers are black, the latter with large white windows.[2]

They frequent a variety of open habitats up to the fringes of forest, whether altered by man or natural. Their diet consists of a variety of flying insects. They may forage alone or in flocks, and emit a weak twittering. Their breeding season and abundance depends much on their region of residence, and a few undertake migrations.[2]
