Rufous-fronted Thornbird Phacellodomus rufifrons

A rather plain thornbird with a long tail and a dark gray eye. Nondescript; look for the brighter rufous forehead that contrasts with an otherwise plain olive-brown back and buff underparts. Found in open areas with scattered trees and savannas; avoids the forest interior. Tends to be very vocal, often singing a squeaky, chattering duet. Look for its enormous stick nests usually located in isolated trees where they hang suspended at the end of branches. Mainly occurs from Bolivia to eastern Brazil, with a disjunct population in northwestern Peru and extreme southern Ecuador.
