About Cyphorhinus phaeocephalus P.L.Sclater, 1860
Cyphorhinus phaeocephalus, commonly called the song wren, is 11.5 to 12.5 cm (4.5 to 4.9 in) long and weighs 25 to 26 g (0.88 to 0.92 oz). Its body is almost uniformly brown, with the breast sometimes paler than other areas. It has a chestnut-colored throat, black bars on its wings and very short tail, and a patch of bare blue skin surrounding the eye. Subspecies of this bird show some variation in color and color intensity; extensive, detailed descriptions are available in Pollock and Agin (2020). Six subspecies of Cyphorhinus phaeocephalus have distinct ranges: C. p. richardsonii is found on the Caribbean side of southeastern Honduras and eastern Nicaragua; C. p. infuscatus lives on the Caribbean side of Costa Rica and northwestern Panama; C. p. lawrencii occurs from central Panama into extreme northwestern Colombia; C. p. propinquus inhabits northern Colombia; C. p. chocoanus is found in western Colombia; and C. p. phaeocephalus ranges from southwestern Colombia to southern Ecuador. The song wren lives in the interior of lowland primary and secondary forest, particularly areas with abundant undergrowth. It avoids dry landscapes and brightly lit areas.
