Chapman's antshrike (Thamnophilus zarumae) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Ecuador and Peru. Chapman's antshrike was originally described as a species but was soon transferred to be a subspecies of the barred antshrike (Thamnophilus doliatus). At the same time a new taxon was described as another subspecies of the barred antshrike (T. d. palamblae). In the late twentieth century Chapman's antshrike again began to be recognized as a separate species with palambae as a subspecies, and a few years later a phylogenetic study showed that it was not closely related to the barred antshrike.
Chapman's antshrike is 14 to 15.5 cm (5.5 to 6.1 in) long and weighs about 22 g (0.78 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those of true shrikes. This species exhibits marked sexual dimorphism though both sexes have a bushy crest. Adult males of the nominate subspecies T. d. zarumae have a black and white streaked... Wikipedia →

Rare
Under 5% of wildlife watchers report a Chapman's Antshrike sighting in Podocarpus National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 360th most-seen of the 446 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chapman's Antshrike in Podocarpus National Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Chapman's Antshrike 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 Chapman's Antshrike sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Chapman's Antshrike is recorded against all the birds logged in Podocarpus National Park (11 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.
