Little Sunangel
Heliangelus micraster
Unmistakable; the only hummingbird within its limited range that has an orange throat patch. Otherwise dark emerald-green overall with a rather short, straight bill. Males and females are similar, but females have a smaller throat patch and a dingier grayish belly. Occurs on the east slope of the Andes from southern Ecuador to northern Peru from around 2,400 to 3,100 m. Visits feeders, but also can be found in the middle levels of temperate forest and edges.
识别特征
The flame-throated sunangel is 10 to 11 cm (3.9 to 4.3 in) long and weighs 3.6 to 4.1 g (0.13 to 0.14 oz). Its straight bill is blackish. Both sexes have dark metallic green upperparts. Their lower breasts are dark metallic green, their bellies grayish, and their vent areas almost white. Their tails are dark steel blue. Adult males of the nominate subspecies have a glittering blue-green frontlet just above the bill, a dark purplish blue chin, and an iridescent yellow-orange gorget with a glittering emerald green border. Adult females lack the blue-green frontlet, their chin is blackish, and their throat is white with green to dusky gray speckles and sometimes a few iridescent reddish orange discs. Juveniles are like the adult female but the male does not have the blackish chin. Males of subspecies H. m. cutervensis have a reddish orange gorget.

In elevation it mostly ranges between 2,300 and 3,400 m (7,500 and 11,200 ft) but has been recorded as low as 1,500 m (4,900 ft).

行为
The flame-throated sunangel is mostly sedentary but disperses altitundinally after the nesting season.<p>The flame-throated sunangel defends foraging areas. It mostly feeds on nectar, usually at flowers at low to medium heights above the ground, within the forest and on its borders. Females often venture further into bushy pastures. It usually clings to flowers to feed rather than hovering at them. It also captures insects by hawking from a perch and by gleaning from vegetation.<p>The flame-throated sunangel's breeding season spans from January to May in Ecuador but has not been defined in Peru. The clutch of two white eggs is incubated by the female. Nothing else is known about the species' breeding phenology.<p>The flame-throated sunangel's call is "a repeated dry 'djit' or more gravelly 'drrt'."

Western Olivaceous Warbler
Iduna opaca
Large buff-colored warbler with a heavy flat bill and long tail. Olive-gray upperparts contrast with the pale bill. The pale lores separates this species from the similar Eastern Olivaceous Warbler and it doesn’t make downward tail movements like Eastern. Song contains several irregular notes and clicks. Found in light woodland gardens, orchards, plantations, oases and areas with dense bushes.
Northern Puffback
Dryoscopus gambensis
Mid-sized bushshrike in which males and females are very different. Males are mostly black and white, with gray on the rump and shoulder. Females are brown on the back and buffy below. Found in a variety of savanna habitats, plus woodland, mangroves, and along forest edge. Generally common and conspicuous bird that often joins mixed-species flocks. The most common vocalization is a rising “kyeeewu,” but also gives scolding and ratcheting calls. Males separated from Black-backed Puffback by the gray rump and shoulder. Females separated from Pringle’s Puffback by their larger size and all-dark bill.
