The buff-breasted earthcreeper (Upucerthia validirostris) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Bolivia, Chile, and Peru. The paper resulted in the "collapse" of the two species with five subspecies into the current one-species, three-subspecies, model. Some authors suggest that further study is needed.
The buff-breasted earthcreeper is 17 to 21 cm (6.7 to 8.3 in) long and weighs 30 to 45 g (1.1 to 1.6 oz). It is a medium-sized earthcreeper with a long and strongly decurved bill. The sexes' plumages are alike. Adults of the nominate subspecies have a pale buffish white supercilium. Their crown, nape, back, rump, and uppertail coverts are dull brownish gray. Their...

Possible
About 30% of wildlife watchers report a Buff-breasted Earthcreeper sighting in Lauca National Park on a given day, based on 244 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 43rd most-seen of the 112 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January and July
In those months about 50% of wildlife watchers report a Buff-breasted Earthcreeper in Lauca National Park on a given day, against about 30% in February, May–June and August–December, the lowest months. Those are among Lauca National Park's wettest months, with about 75 mm of rain a month against almost none in May.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Buff-breasted Earthcreeper sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Lauca National Park, in our data
Lauca National Park is the only park on Wallace's Line with enough records to rate Buff-breasted Earthcreeper sightings: about 30% of wildlife watchers there report one on a given day.
Same genus: Upucerthia
The closest relatives of the Buff-breasted Earthcreeper that you can see in Lauca National Park (genus Upucerthia, Typical Earthcreepers) are White-throated Earthcreeper (about 20%) and Straight-billed Earthcreeper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Buff-breasted Earthcreeper is recorded against all the birds logged in Lauca National Park (244 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.
