Taxonomy

Choco Tyrannulet has been split from this taxon.[1][2][3]

Subspecies

Zimmerius chrysops has four subspecies[1]:

The subspecies flavidifrons and the southern population of subspecies chrysops (south of Rio Marañon) has been transferred to Peruvian Tyrannulet. Gill and Donsker recognise Coopmans's Tyrannulet, Zimmerius minimus as a separate species.[2]
