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.

GBIF citizen-science records
It is estimated from how often the Nightingale Wren is recorded against all the birds logged in Braulio Carrillo National Park (101 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
