The spot-backed antshrike (Hypoedaleus guttatus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Argentina, Brazil, and Paraguay. The spot-backed antshrike was described by the French ornithologist Louis Pierre Vieillot in 1816 and given the binomial name Thamnophilus guttatus. The genus Hypoedaleus was erected by the German ornithologists Jean Cabanis and Ferdinand Heine in 1860 with the spot-backed antshrike as the type species. The name of the genus is from the Ancient Greek hupoidaleos meaning "somewhat swollen". The specific epithet is from the Latin guttatus meaning "spotted" or "speckled".
The spot-backed antshrike is the only member of genus Hypoedaleus and it has no subspecies. The spot-backed antshrike is a large antbird, 20 to 21 cm (7.9 to 8.3 in) long.

Adult males have a black crown, nape, and upperparts spotted with white and a brownish black tail with white bars. Their throat and breast are white and their sides pale gray. Their... Wikipedia →

Rare
Under 5% of wildlife watchers report a Spot-backed Antshrike sighting in São Paulo on a given day, based on 117 verified sightings from GBIF citizen-science data. It is the 182nd most-seen of the 353 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 Spot-backed Antshrike in São Paulo on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Spot-backed 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 São Paulo, in our data
São Paulo is the only city on Wallace's Line with enough records to rate Spot-backed 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 Spot-backed Antshrike is recorded against all the birds logged in São Paulo (117 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.
