The mouse-colored thistletail (Asthenes griseomurina) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Ecuador and Peru. The mouse-colored thistletail and many other thistletails were previously treated as subspecies of the white-chinned thistletail (A. fuliginosa). All of them were in genus Schizoeaca but genetic data showed that the genus is embedded within Asthenes. The mouse-colored thistletail possibly should again be treated as a fifth subspecies of the white-chinned. The mouse-colored thistletail is monotypic.
The mouse-colored thistletail is 18 to 21 cm (7.1 to 8.3 in) long and weighs 15.5 to 19 g (0.55 to 0.67 oz). The sexes have the same plumage.

Their tail is long and deeply forked with few barbs at the feather ends that give a ragged appearance.

With luck
About 10% of wildlife watchers report a Mouse-colored Thistletail sighting in Podocarpus National Park on a given day, based on 183 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th most-seen of the 446 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January and November
In those months about 20% of wildlife watchers report a Mouse-colored Thistletail in Podocarpus National Park on a given day, against under 5% in July, September and December, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Mouse-colored Thistletail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Podocarpus National Park, in our data
Podocarpus National Park is the only park on Wallace's Line with enough records to rate Mouse-colored Thistletail sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Furnariidae
The closest relatives of the Mouse-colored Thistletail that you can see in Podocarpus National Park (family Furnariidae, Ovenbirds and Woodcreepers) are Pearled Treerunner (about 30%), Rufous Spinetail (about 20%) and Olivaceous Woodcreeper (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mouse-colored Thistletail is recorded against all the birds logged in Podocarpus National Park (183 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.
