The eastern woodhaunter (Automolus subulatus), also known as the Amazonian woodhaunter, is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela.
At one time what is now the eastern woodhaunter was included in genus Hyloctistes but molecular phylogenetic studies showed that Hyloctistes is embedded within Automolus. Even before the generic merger, the eastern woodhaunter's taxonomy was unsettled, and it remains so. Its two subspecies were included with four others in what was then called the striped woodhaunter. In the early twenty-first century several authors split the four Central American and western South American subspecies from the striped woodhaunter and named the new species the western woodhaunter (then H. virgatus, now A. virgatus). They gave the remaining two subspecies the English name "eastern woodhaunter" and by the principle of priority retained the binomial A. subulatus. By late 2023 the International Ornithological Committee, BirdLife International's Handbook of the Birds of the World (HBW), and the Clements taxonomy had adopted the split... Wikipedia →

Rare
Under 5% of wildlife watchers report a Striped Woodhaunter sighting in Piedras Blancas National Park on a given day, based on 55 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 230th most-seen of the 344 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.
July–August and October
In those months about 10% of wildlife watchers report a Striped Woodhaunter in Piedras Blancas National Park on a given day, against under 5% in September and November–June, the lowest months. Those are among Piedras Blancas National Park's wettest months, with about 510 mm of rain a month against 55 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Striped Woodhaunter sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 12 parks where we can rate Striped Woodhaunter sightings, Piedras Blancas National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Arenal Volcano National Park (Costa Rica, under 5%).
Same family: Furnariidae
The closest relatives of the Striped Woodhaunter that you can see in Piedras Blancas National Park (family Furnariidae, Ovenbirds and Woodcreepers) are Cocoa Woodcreeper (about 40%), Wedge-billed Woodcreeper (about 30%) and Streak-headed Woodcreeper (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Striped Woodhaunter is recorded against all the birds logged in Piedras Blancas National Park (55 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.
