The rufous hornero (Furnarius rufus) is a medium-sized ovenbird in the family Furnariidae. It occurs in eastern South America and is the national bird of Argentina. Also known as the red ovenbird, it is common in savannas, second-growth scrub, pastures, and agricultural land and is synanthropic. Its range includes midwestern, southeastern, and southern Brazil, Bolivia, Paraguay, Uruguay, and northern and central Argentina, extending as far south as northern Patagonia. The species is most closely related to the crested hornero of Paraguay and Argentina. There are four accepted subspecies.
The rufous hornero is medium-sized with a square tail and very slightly decurved bill. The plumage is overall reddish brown with a dull brown crown and a whitish throat. Sexes are alike and juvenile birds are slightly paler below (probably because they are cleaner). Rufous horneros feed on insects and other arthropods obtained by foraging on the ground while walking. They sometimes feed on scraps such as bread crumbs. Songs in the rufous hornero are sexually distinct. The rapid trill that is usually heard as part of the duet is faster in the male and slower in the female, and both beat their wings at their sides while singing and the wings beat at the same rate as their trill. Thus, while watching an observer may identify the sex by how fast their wings beat while singing. Wikipedia →

Likely
About 40% of wildlife watchers report a Rufous Hornero sighting in Belo Horizonte on a given day, based on 705 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 220 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
October and December
In those months about 50% of wildlife watchers report a Rufous Hornero in Belo Horizonte on a given day, against about 20% in April and May, the lowest months. Those are among Belo Horizonte's wettest months, with about 180 mm of rain a month against 5 mm in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Rufous Hornero sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Rufous Hornero is recorded against all the birds logged in Belo Horizonte (705 verified sightings), 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.
