White-crested tyrannulet
Species of bird
The white-crested tyrannulet (Serpophaga subcristata) is a small species of bird in the family Tyrannidae. It is found in woodland and open habitats with scattered bushes and trees in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. It is closely related to the white-bellied tyrannulet, but unlike that species the belly of the white-crested tyrannulet is yellow. The recently described Straneck's tyrannulet is extremely similar to the white-crested tyrannulet and was for a long time confused with that species; the two are generally best separated by voice.
