Tumbes Hummingbird
Thaumasius baeri
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.
识别特征
The Tumbes hummingbird is 8 to 11 cm (3.1 to 4.3 in) long and weighs about 4.5 g (0.16 oz). The sexes are essentially alike. They have a nearly straight black bill. Their upperparts are pale golden green and their underparts pale grayish that becomes white on the belly. The tail feathers are pale green; the inner ones have bronzy tips and the outer ones a dusky gray band near the end and tips that are whitish in the male and grayish in the female.
分类信息
This species was formerly placed in the genus Leucippus. A molecular phylogenetic study published in 2014 found that Leucippus was polyphyletic. To resolve the polyphyly the Tumbes hummingbird and the spot-throated hummingbird (Taphrospilus hypostictus) were moved by most taxonomic systems to the resurrected genus Thaumasius. However, BirdLife International's Handbook of the Birds of the World retains it in Leucippus.<p>The Tumbes hummingbird is monotypic.

行为
The Tumbes hummingbird is mostly sedentary though it may make some seasonal movements.<p>The Tumbes hummingbird forages for nectar from the understory to the mid-strata, though details of the flowering plants it favors are lacking. In addition to nectar, it feeds on small arthropods.<p>The Tumbes hummingbird's breeding phenology and nest have not been described.<p>The Tumbes hummingbird's song is "a complex series of chips and wheezing electric warbles." Its calls have been described as "a gruff dzee and chips."

Stout Cisticola
Cisticola robustus
Large and relatively colorful cisticola with a rufous cap and back of the neck, and a black-streaked back. Found in lush grassland habitat. The song consists of chirping introductory notes followed by a long buzz. As with other cisticolas, habitat and vocalizations are important to identification. Very similar to Aberdare Cisticola, but lacks streaking on the back of the neck. Fairly similar to Croaking Cisticola, but has rufous on the head.
Amazonian Scrub-Flycatcher
Sublegatus obscurior
A confusing flycatcher, fairly small and nondescript. Look for the short bill and round head, sometimes raised into a slight crest. Dull grayish-brown head shows only a hint of a paler line above eye. Chest is paler gray, which blends into the pale yellow belly. Wingbars are present but not bold. Larger and lankier than a beardless-tyrannulet; looks rather like a diminutive Myiarchus flycatcher. Very similar to Southern Scrub-Flycatcher, which may overlap during the Austral winter, but note the overall darker coloration of Amazonian.
Helmeted Manakin
Chiroxiphia galeata
Males are striking with a mostly glossy black body, but with a red forehead, crest, and back. Females are uniformly olive-green and also crested. Locally common in gallery forests embedded in savannas where it often accompanies mixed-species flocks. The song is a trilling series of alternately soft and loud whistles.
