About the Lesser Greenlet

The lesser greenlet (Pachysylvia decurtata) is a small passerine bird in the family Vireonidae, the vireos, greenlets, and shrike-babblers. It is found in Mexico, every Central American country, Colombia, Ecuador, and Peru.

The lesser greenlet's further taxonomy is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World assign it these six subspecies: P. d. brevipennis (Giraud Jr, 1851) P. d. dickermani (Parkes, 1991)
