Bird name: Chestnut Bellied Seed Finch
Latin: Oryzoborus angolensis
Other: Split from Lesser Seed-Finch • Semillero sabanero, arrocero buchicastaño, cacagüero, tawa tawa, curió (Es) • Curió (Br)
Family: Thraupidae • Tanagers, Seed-finches
Range: East of Andes - Colombia, Ecuador, Peru, Bolivia, Paraguay, Brazil etc

The male Chestnut-Bellied Seed-Finch has a large bill, chestnut belly, and is otherwise black with a white mark on wing. All the individuals I saw in eastern Ecuador were similar to the bird pictured above, with a mottled aspect to the chestnut underparts.

The female is brown. The photo below is probably one, based on bill shape.

The Chestnut-Bellied Seed-Finch used to be grouped with the Thick-billed Seed-finch as the Lesser Seed-Finch.More photos...

The Red Eyed Vireo has a red iris, thin black stripe above white supercilium, light underparts, yellowy green upperparts.

There are resident North American and South American populations, both migrating. A South-American resident group is called Chivi Vireo - birds have brown eyes and yellow vent.

The Chivi Vireo pictured above was seen at Serra dos Tucanos Lodge near Rio in September. Red-eyed Vireos are seen in many forests of South America, many for example in Oriente, Ecuador, in March. We saw a migrant Red-eyed Vireo at the Finca Hartmann in western Panama, in May (further below).More photos...

Bird name: Silver Beaked Tanager
Latin: Ramphocelus carbo
Other: Sangre de toro apagado, toche negro (Es) • Tie-sangue (Br)
Family: Thraupidae • Tanagers
Range: Bolivia, Brazil, Colombia, Ecuador, Guyanas, Peru, Paraguay
Similar: Female Guira Tanager

The Silver-beaked Tanager is quite common over its range. It seemed to be the default tanager approaching Tena and into the Upper Napo region of Ecuador. Also the most common tanager in the Pantanal in August, where it was often seen beside rivers and in fruiting trees. Also seen in Parà.

The male Silver-beaked Tanager (above) is easy to identify - dark red with bright lower bill. It can look black in weak light.

Females (below) are browner - but still reddish - with less contrast on the bill. They look similar to female Brazilian Tanagers, but fortunately the two ranges do not overlap.More photos...

There’s no mistaking the Magpie Tanager, with its strong black and white markings, which are reminiscent of the European Magpie, its large size, long tail and bright yellow irises. Its distribution is split into two parts, one comprising southeastern Brazil.

Also seen in Ecuador near Tena and the eastern lowlands.More photos...
