Rare
Under 5% of wildlife watchers report a Chestnut-backed Antshrike sighting in Manu National Park on a given day, based on 101 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 385th most-seen of the 641 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Chestnut-backed Antshrike in Manu National Park on a given day, against under 5% in October to August, the lowest months. That is one of Manu National Park's driest months, with about 90 mm of rain against 290 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Chestnut-backed Antshrike sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate Chestnut-backed Antshrike sightings, Manu National Park ranks 4th at under 5%. The best odds are in Tijuca National Park (Brazil, about 20%), Amboró National Park (Bolivia, about 20%) and Serra dos Órgãos National Park (Brazil, about 20%).

GBIF citizen-science records
It is estimated from how often the Chestnut-backed Antshrike is recorded against all the birds logged in Manu 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.
