The red-crowned ant tanager (Habia rubica) is a medium-sized passerine bird from tropical America.

The red-crowned ant tanager was formally described in 1817 by the French ornithologist Louis Pierre Vieillot.

[4] The red-crowned ant tanager is now the only species placed in the genus Habia that was introduced in 1840 by Edward Blyth.

The adult male of the nominate subspecies is dull reddish brown with a brighter red throat and breast.

[8] This bird is a resident breeder from Mexico south to Paraguay and northern Argentina, and on Trinidad.

In Central America and Trinidad they frequently attend army ant columns, and in the lowland forests of southeastern Brazil they may be a nuclear species of understory mixed-species feeding flocks – though further uphill, e.g. in the Serra de Paranapiacaba, they seem to join such flocks only rarely and prefer to follow the ants on their own.
