The rufous-bellied thrush (Turdus rufiventris) is a songbird of the thrush family (Turdidae). Its distribution covers most of eastern and southeastern Brazil from the states of Maranhão south to Rio Grande do Sul, Bolivia, Paraguay, Uruguay, and central regions of Argentina.
It is one of the most common birds across much of southeastern Brazil, and is known there under the name sabiá-laranjeira (Portuguese pronunciation: [sabiˈa laɾɐ̃ˈʒejɾɐ]). It was famously referred to in the well-known first strophe of the Brazilian nationalist poem Canção do Exílio. The rufous-bellied thrush has been the state bird of São Paulo since 1966, and the national bird of Brazil since 2002. It is highly regarded in Brazil, where its song is often heard in the afternoons, but specially during the nights between August and November, where thousands of them sing until the sunrise, and is often seen as "the spirit of the Brazilian commoner".
This species is named after its distinctive reddish-orange underparts. Rufous-bellied thrushes can reach a length of 25 cm and weigh up to 68 g (male) or 78 g (female), though weights of about 59 g for males and 64 g for females are more usual. Contrary... Wikipedia →

Likely
About 60% of wildlife watchers report a Rufous-bellied Thrush sighting in Niterói on a given day, based on 1,003 verified sightings from GBIF citizen-science data.

Across all the parks we cover, that three-hour window holds the most Rufous-bellied Thrush 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-bellied Thrush is recorded against all the birds logged in Niterói (1,003 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.
