The brown cacholote (Pseudoseisura lophotes) is a medium-sized bird of the ovenbird family Furnariidae. It was described by Ludwig Reichenbach in 1853, with its subspecies, argentina, described in 1960 by Kenneth Carroll Parkes. It is nonmigratory, and is found in the forests and parks of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Unlike many other birds, the brown cacholote builds large, pitcher-like nests year-round, each weighing many times more than the bird itself. Breeding begins in mid-November, with both parents sharing the responsibility for taking care of the nest equally. Incubation takes 17–20 days, and nestlings fledge at 19 days. They are omnivorous, primarily eating various arthropods, along with the eggs of other birds, fruits, and grain. The causes of death in adults is not well researched; however, nestlings are subject to parasitism from various insects. Egg success rate is 59%. They are a least-concern species.
The brown cacholote was first described as Homorus lophotes by Ludwig Reichenbach in 1853 in his book Handbuch der speciellen Ornithologie. It was later moved into the genus Pseudoseisura by Miguel Lillo in 1902. The... Wikipedia →

With luck
About 10% of wildlife watchers report a Brown Cacholote sighting in El Impenetrable National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 147th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Brown Cacholote in El Impenetrable National Park on a given day, against under 5% in March, May, July and September–November, the lowest months. That is one of El Impenetrable National Park's driest months, with about 35 mm of rain against 120 mm in March. 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 Brown Cacholote sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Brown Cacholote sightings, El Impenetrable National Park has the highest daily chance: about 10%. Next come Iberá National Park (Argentina, under 5%).
Same family: Furnariidae
The closest relatives of the Brown Cacholote 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 Brown Cacholote is recorded against all the birds logged in El Impenetrable National Park (24 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.
