The mouse-colored tyrannulet (Nesotriccus murinus) is a species of bird in subfamily Elaeniinae of the tyrant flycatchers family Tyrannidae. It is found from Costa Rica and Panama south to Brazil and northern Argentina. The mouse-colored tyrannulet has sometimes been split into two species, the northern mouse-colored tyrannulet and the southern mouse-colored tyrannulet.
The mouse-colored tyrannulet was formally described in 1825 by the German naturalist Johann Baptist von Spix under the binomial name Platyrhynchus murinus based on a specimen from Brazil. The specific epithet is Modern Latin meaning "mouse-grey" from Latin murinus meaning "of mice". The type locality has been restricted to Juazeiro in the state of Bahia in eastern Brazil. The mouse-colored tyrannulet is now one of four species placed in the genus Nesotriccus that was introduced by Charles Haskins Townsend in 1895.

It is the 352nd most-seen of the 363 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
In every month with enough records, under 5% of wildlife watchers report a Mouse-Coloured Tyrannulet in Panama City on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Mouse-Coloured Tyrannulet is recorded against all the birds logged in Panama City (10 verified sightings), 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.
