Olive-backed Euphonia
Olive-backed Euphonia Euphonia gouldi forages principally at middle to upper levels in the forest, but will occasionally visit edges or even the understory, and is, like most euphonias, mostly found in pairs or small groups. Both sexes of the Olive-backed Euphonia are rather distinctively plumaged, being largely deep green with rufous over the posterior underparts, with males (on the picture) having a small yellow forecrown, replaced by rufous in females. Stays mainly in canopy, but occasionally descends to middle levels. Most fruit taken while bird perched, rarely while in flight. Swallows fruits whole, or mashes them and discards skin, and sometimes also seed, before swallowing pulp (Birds of the world).
