Sooty-headed Wren

The sooty-headed wren (Pheugopedius spadix) is a species of bird in the family Troglodytidae. It is found in Colombia and Panama. == Taxonomy and systematics == The sooty-headed wren was previously treated as conspecific with the black-throated wren (Pheugopedius atrogularis) but significant differences in their plumage, song, and ranges demanded their separation. According to the International Ornithological Committee (IOC) the sooty-headed wren is monotypic. However, the Clements taxonomy, BirdLife International (BLI), and the Cornell Lab of Ornithology's Birds of the World recognize two subspecies, the nominate Pheugopedius spadix spadix and P. s. xerampelinus. == Description == The sooty-headed wren is 14.5 cm (5.7 in) long. The nominate adults' crown, shoulders, and back are dull blackish and the rump bright chestnut. Their tail is chestnut with bold black bars. Much of their face is black with white streaks. Their chin and throat are black and contrast with the bright chestnut lower throat and chest. The belly is a duller grayish brown between reddish brown flanks. The juvenile is duller than the adult and has less contrast between the areas of different color. P. s. xerampelinus is overall paler than the nominate and has less extensive reddish brown on the flanks. ==…
