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.

Under 5% of wildlife watchers report a Nightingale Wren sighting in Tapantí-Macizo de la Muerte National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 458th most-seen of the 467 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year

GBIF citizen-science records
It is estimated from how often the Nightingale Wren is recorded against all the birds logged in Tapantí-Macizo de la Muerte National Park (5 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.
