Empidonax oberholseri (Dusky Flycatcher)

Language: Spanish

Wikipedia Abstract

The American dusky flycatcher, or simply dusky flycatcher, (Empidonax oberholseri) is a small, insectivorous passerine of the tyrant flycatcher family. The dusky flycatcher is one of many species in the genus Empidonax. These species are very similar in appearance and behavior, and they are notoriously difficult to differentiate. The best characteristics for distinguishing these species are voice, breeding habitat, and range.
