The short-billed canastero (Asthenes baeri) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. The short-billed canastero's taxonomy is unsettled.
The Clements taxonomy does not recognize neiffi, assessing it as a clinal variant of chacoensis. This article follows the three-subspecies model. The short-billed canastero is 14 to 15 cm (5.5 to 5.9 in) long and weighs 10 to 18 g (0.35 to 0.63 oz). It has a short and thick bill, and is more similar to the wholly unrelated little thornbird (Phacellodomus sibilatrix) than to other canasteros. The sexes have the same plumage. Adults of the nominate subspecies have an indistinct wide grayish supercilium on an otherwise dull grayish brown face. Their crown is dull gray-brown, their back a slightly grayer brown, and their rump and uppertail... Wikipedia →

Rare
Under 5% of wildlife watchers report a Short-billed Canastero sighting in Iberá National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 267th most-seen of the 284 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Short-billed Canastero in Iberá National Park 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 Short-billed Canastero sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Short-billed Canastero sightings, Iberá National Park ranks 2nd at under 5%. The best odds are in El Impenetrable National Park (Argentina, about 10%).
Same family: Furnariidae
The closest relatives of the Short-billed Canastero that you can see in Iberá National Park (family Furnariidae, Ovenbirds and Woodcreepers) are Rufous Hornero (about 80%), Greater Thornbird (about 60%) and Yellow-chinned Spinetail (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Short-billed Canastero is recorded against all the birds logged in Iberá National Park (10 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.
