Many-spotted Hummingbird
Taphrospilus hypostictus
Large hummingbird of Andean cloud forest. Ranges along the east slope of the Andes from far southern Colombia south to Bolivia. Sexes similar. Note white spot behind eye and white underparts boldly spotted with green. Similar to female Violet-fronted Brilliant but lacks blue forehead and white mustache stripe.

识别特征
The many-spotted hummingbird is 10.5 to 11.4 cm (4.1 to 4.5 in) long and weighs 6.7 to 9 g (0.24 to 0.32 oz). Both sexes have a slightly decurved black bill about 2.3 cm (0.91 in) long, and their plumage is very similar. Adults' upperparts are grass green to coppery bronze and the underparts white. The underparts except the central belly are thickly spotted with green, the female's somewhat less heavily. Their tail is blue-green with dusky gray tips to the feathers. Juveniles are the same with the addition of buffy fringes on the head feathers.
分类信息

分布与栖息地
The many-spotted hummingbird's primary range is the eastern slope of the Andes from Ecuador's Napo Province through eastern Peru into central Bolivia. It has also been documented in southern Colombia. The International Ornithological Committee places it Brazil and the Clements taxonomy in Argentina. However, the South American Classification Committee of the American Ornithological Society has no records from Brazil; undocumented sight records from Argentina lead the committee to list it as hypothetical in that country.<p>The many-spotted hummingbird inhabits the interior and edges of humid foothill and subtropical forest, favoring small ravines. In elevation it mostly ranges between 400 and 1,500 m (1,300 and 4,900 ft) but has been found as high as 2,800 m (9,200 ft) in Peru. It is most numerous around 600 m (2,000 ft).

Golden-breasted Puffleg
Eriocnemis mosquera
A fairly large hummingbird of high-elevation forest in the Andes in Colombia and Ecuador. Mostly green with an obvious golden sheen on the breast and white puffs on each leg. Long forked tail is greenish-bronze (not blackish or bluish). Sexes alike. Occurs from around 3,000–3,600 m, where it can be found in forest and edges. Visits feeders.
Antillean Nighthawk
Chordeiles gundlachii
Long-winged nightbird with intricate brown and gray patterning. Very similar to Common Nighthawk, best distinguished by voice. Gives a rapid series of hard, buzzy notes: "drik-rik-rik-rik." A Caribbean species; in the U.S., found only on the Florida Keys. Prefers open areas with mix of grass, bare ground, and shrubs. Nocturnal but can be seen hunting around dawn and dusk, searching for insects in flight.
Black-headed Grosbeak
Pheucticus melanocephalus
Males are black-and-orange like an oriole, but stockier with a very thick bill. Nonbreeding males, females, and immatures typically have an orangey wash across breast with fine dark streaking on sides. Underwing coverts are always yellow. Bill usually looks bicolored, darker above and paler below. Fairly common in a variety of woodlands including mountain forests, thickets along desert streams, and backyards. Winters in Mexico. Regularly visits feeders. Listen for sweet robinlike song and squeaky call. Compare females and immatures with extremely similar Rose-breasted Grosbeak, which is usually identifiable by range. Black-headed usually has sparser and finer streaking on the underparts and more orange tones.
