Fulvous-vented Euphonia

A plain hummingbird found in dry forest and scrub in southwestern Ecuador and northwestern Peru. It is dull green with light gray underparts, a white spot behind the eye, and a thick, slightly curved bill. Some birds show very faint spots on the throat. Similar to Spot-throated Hummingbird, but throat markings are much less conspicuous or entirely absent. Ranges are also different; Tumbes Hummingbird is found only on the Pacific side of the Andes and does not reach the Marañon drainage.

Robust black-and-white bushshrike. There is a pale cinnamon wash on the belly and a white stripe across the top of the wing. Found in dense microhabitats within forest, woodland, thickets, and gardens. Not particularly shy, but spends most of its time in dense cover, usually in pairs. Highly vocal bird with a variety of calls. The song is a synchronized duet of hollow hoots from the male and ratcheting calls from the female. Has a very similar color pattern to other boubous, but its underparts are paler than those of Southern Boubou and darker than those of Swamp Boubou. Has a white stripe on the wing, unlike Zanzibar Boubou.

Specialized, slender prinia-like babbler. Restricted to lowland grassy riverine plains, where it typically stays low in the vegetation in small flocks, flushing only reluctantly. If seen, note very long tail, white throat, and streaking all over the body. Shy and difficult to see; more readily detected by its bubby, warbling song.
