The lined antshrike is 16 to 17 cm (6.3 to 6.7 in) long and weighs 26 to 28 g (0.92 to 0.99 oz).

Possible
About 20% of wildlife watchers report a Chestnut-backed Antshrike sighting in Niterói on a given day, based on 261 verified sightings from GBIF citizen-science data. It is the 23rd most-seen of the 116 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February and December
In those months about 30% of wildlife watchers report a Chestnut-backed Antshrike in Niterói on a given day, against about 10% in April–May and November, the lowest months. Those are among Niterói's wettest months, with about 190 mm of rain a month against 40 mm in August.
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.
Among the best
Of the 6 cities where we can rate Chestnut-backed Antshrike sightings, Niterói ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Rio de Janeiro (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 Niterói (261 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.
