Rare
Under 5% of wildlife watchers report a Mouse-colored Antshrike sighting in Anavilhanas National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 182nd most-seen of the 291 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Mouse-colored Antshrike in Anavilhanas National Park on a given day, against under 5% in April–August and October–December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Mouse-colored Antshrike sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 parks where we can rate Mouse-colored Antshrike sightings, Anavilhanas National Park ranks 4th at under 5%. The best odds are in Brownsberg Nature Park (Suriname, about 50%), Amacayacu National Natural Park (Colombia, about 20%) and Yasuní National Park (Ecuador, about 20%).
GBIF citizen-science records
It is estimated from how often the Mouse-colored Antshrike is recorded against all the birds logged in Anavilhanas National Park (16 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.
