The grey-crested cacholote (Pseudoseisura unirufa) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, and Paraguay. The grey-crested cacholote is monotypic. It was previously considered a subspecies of the Caatinga cacholote (P. cristata) which was then called the rufous cacholote. The two taxa were split following the data in a paper published in 2000. Confusingly, and contrary to the suggestion of the 2000 paper's authors, the South American Classification Committee of the American Ornithological Society, the Clements taxonomy, and some field guide authors call P. unirufa the rufous cacholote.
The grey-crested cacholote is 20 to 21 cm (7.9 to 8.3 in) long and weighs 42 to 57 g (1.5 to 2.0 oz). It is a large, crested, furnariid. The sexes have the same plumage. Adults are mostly bright reddish-rufous that is somewhat paler on their underparts. Their crest varies from entirely rufous to almost entirely grayish. The center of their throat has an orange tinge. Their flight feathers have fuscous tips and the ends of the tail feathers lack barbs. Their iris is yellow to buff...

With luck
About 10% of wildlife watchers report a Rufous Cacholote sighting in Madidi National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 76th most-seen of the 239 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Rufous Cacholote is recorded against all the birds logged in Madidi National Park (23 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.
