About the Nightingale Wren

The northern nightingale-wren (Microcerculus philomela), or nightingale wren, is a species of passerine bird in the family Troglodytidae. It is found in Belize, Costa Rica, Guatemala, Honduras, Mexico, and Nicaragua. The northern nightingale-wren forms a species pair with the southern nightingale-wren (Microcerculus marginatus) and was in the past considered conspecific with it. It is currently treated as a species in its own right by the International Ornithological Committee (IOC) and the Clements taxonomy, though under different English names. It is monotypic.

The northern nightingale-wren is 10 to 11.5 cm (3.9 to 4.5 in) long; seven males weighed 17.4 to 21.5 g (0.61 to 0.76 oz) and four females 16.4 to 17.4 g (0.58 to 0.61 oz). Adults are almost entirely dark brown, but with a dark gray throat and breast. Black tips on feathers of both the upper- and undersides give a scalloped appearance. Juveniles are similar though the scaling on their upperparts is darker and that on the underparts is whitish to pale gray.
