The yellow-chinned spinetail (Certhiaxis cinnamomeus) is a passerine bird found in the tropical New World from Trinidad and Colombia south to Argentina and Uruguay. It is a member of the South American ovenbird family Furnariidae.
The yellow-chinned spinetail was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the treecreepers in the genus Certhia and coined the binomial name Certhia cinnamomea. The specific epithet is from Modern Latin cinnamomeus meaning "cinnamon-coloured". Gmelin based his description on the "Cinnamon creeper" that had been described in 1782 by the English ornithologist John Latham. Latham had examined a specimen in the British Museum. Latham did not specify the origin of the specimen but in 1902 Hans von Berlepsch and Ernst Hartert designated the type locality as Cayenne. The yellow-chinned spinetail is now placed with the red-and-white spinetail in the genus Certhiaxis that was introduced in 1844 by the French naturalist René Lesson.

Possible
About 20% of wildlife watchers report a Yellow-chinned Spinetail sighting in El Impenetrable National Park on a given day, based on 54 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 84th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October
In that month about 40% of wildlife watchers report a Yellow-chinned Spinetail in El Impenetrable National Park on a given day, against about 10% in January, March, May–June and August–September, the lowest months. December has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-chinned Spinetail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 12
Of the 12 parks where we can rate Yellow-chinned Spinetail sightings, El Impenetrable National Park ranks 4th at about 20%. The best odds are in Parque Estadual Encontro das Águas (Brazil, about 50%), Iberá National Park (Argentina, about 50%) and Caroni Swamp (Trinidad and Tobago, about 30%). All parks ranked.
Same family: Furnariidae
The closest relatives of the Yellow-chinned Spinetail that you can see in El Impenetrable National Park (family Furnariidae, Ovenbirds and Woodcreepers) are Narrow-billed Woodcreeper (about 70%), Rufous Hornero (about 60%) and Sooty-fronted Spinetail (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-chinned Spinetail is recorded against all the birds logged in El Impenetrable National Park (54 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.
