Deconychura pallida
In 3 days <5% in a week ~10%
The mournful long-tailed woodcreeper (Deconychura pallida), also known as the southern long-tailed woodcreeper, is a species of bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela.
The mournful long-tailed woodcreeper was formerly considered to be part of the former long-tailed woodcreeper (Deconychura longicauda) with what are now the northern long-tailed woodcreeper (keeping D. longicauda) and the little long-tailed woodcreeper (D. typica). BirdLife International's Handbook of the Birds of the World (HBW) has treated them separately since the 2010s, and the International Ornithological Committee (IOC) followed suit in July 2023. However, the North American and South American Classification Committees of the American Ornithological Society and the Clements taxonomy treat the long-tailed woodcreeper as one species. The AOS notes that it probably consists of at least two and possibly three species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Mournful Long-tailed Woodcreeper sighting in Anavilhanas National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 275th most-seen of the 291 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

GBIF citizen-science records
It is estimated from how often the Mournful Long-tailed Woodcreeper is recorded against all the birds logged in Anavilhanas National Park (5 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.
