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 was originally described in 1838 as Sylvicola decurtata. It later was renamed Hylophilus decurtatus and later still moved to its present genus Pachysylvia and its specific epithet returned to decurtata to match the feminine gender of the genus.

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)
