Russet backed Oropendola
The Russet-backed Oropendola belongs to the Icteridae family. It is a medium-sized oropendola, fairly common in lowlands but seems to be scarce in montane forest. It lives in the Andes, where it is usually the only oropendola and it is unlikely to be confused. This species is generally olive overall with warmer rufous tones on back and rump.
The bill can change to dark blackish in the Amazonian lowlands and it can be yellowish in Andes with ellow outer tail feathers like other oropendolas. It can typically be seen in flocks that forage in the canopy, sometimes in mixed flocks with other oropendolas or caciques. You can see it on our birding tours in the Manu National Park.
