The Swallow-tailed Manakin is a passerine bird from the Pipridae family. Also known as the dancing tangará (Santa Catarina). The name “Tangará” supposedly derives from the Tupi ata, to walk; and carã, around; corresponding to the Castilian word saltarin. It is about 13 centimetres long and has strong sexual dimorphism. Males have sky-blue plumage, a black tail with two central feathers that are longer than the others and a bright red crown on top of the head. The youngest are olive-green, differing from the females in the red crown that appears before the feathers change on the rest of the body; they only reach adult plumage at two years of age. The females are dark green and have a longer tail than the males, making them slightly larger than the latter. They are also quieter.
