About the Marble-Faced Bristle-Tyrant

The marble-faced bristle tyrant (Pogonotriccus ophthalmicus) is a species of passerine bird in the family Tyrannidae, the tyrant flycatchers.

That genus was later merged into genus Phylloscartes. Beginning in 2016 taxonomic systems resurrected Pogonotriccus for this species and a few others.

The marble-faced bristle-tyrant has three subspecies, the nominate P. o. ophthalmicus (Taczanowski, 1874), P. o. ottonis (Berlepsch, 1901), and P. o. purus (Todd, 1952). P. o. ottonis had been treated as a separate species by some early authors.

The marble-faced bristle tyrant is about 11.5 to 12 cm (4.5 to 4.7 in) long and weighs 10 to 11 g (0.35 to 0.39 oz). The sexes have the same plumage.
