Yellow-eared Toucanet
Selenidera spectabilis
Small toucan with distinctive plumage pattern. Male has black body with bright yellow cheek patch; also note olive back and orange patch on flanks. Female similar; she lacks the yellow cheek patch but still has bright yellow-teal skin around the eye. Found in the forest canopy, usually in pairs or small family groups. Feeds on fruits, and sometimes perches conspicuously on an open branch.
识别特征
The yellow-eared toucanet is 36 to 38 cm (14 to 15 in) long and weighs 175 to 245 g (6.2 to 8.6 oz). It is the largest and most distinctively plumaged member of its genus. Males and females have the same bill pattern but the female's bill is shorter. The bill has a vertical black line at its base. The maxilla is yellow with a triangle of olive brown below it narrowing from the base and horn-colored tips on the tomium. The mandible is dark olive to brownish black. Adult males have a black cap that extends down the hindneck, blue to green bare skin around the eye, and a large yellow tuft that extends back behind the eye. Their back and uppertail coverts are green and their tail blackish. They are black from their chin to their belly with a yellow patch on the flank, chestnut thighs, and red undertail coverts. Adult females have a chestnut forehead and hindneck and lack the male's yellow ear tuft. Immatures are duller than adults and the pattern on their bills is less distinct. Males' black is sooty and females' chestnut is brownish.
分类信息
Despite its placement in genus Selenidera, the yellow-eared toucanet might be more closely related to the mountain toucans of genus Andigena. It is monotypic.

分布与栖息地
The yellow-eared toucanet is found from northeastern Honduras south through Nicaragua, Costa Rica, Panama, and western Colombia into extreme northwestern Ecuador. It inhabits wet forested slopes and ridges, nearby secondary forest, and fruit trees close to the forest edge. In elevation it mostly ranges between 300 and 1,100 m (980 and 3,600 ft) but occurs as low as sea level. It also occurs as high as about 1,500 m (4,900 ft) but in Honduras is unknown above 500 m (1,600 ft).

行为
The yellow-eared toucanet is known to move from higher to lower elevations after the breeding season in Costa Rica and Panama, but whether this is universal or done only by younger birds is not known.<p>The yellow-eared toucanet usually forages in pairs or small groups, and usually from the forest's mid level to the canopy. It does feed at fruiting bushes near the ground. Its diet has not been detailed but is known to be mostly fruit and also include arthropods and lizards.<p>The yellow-eared toucanet's breeding season in much of its range is from April to August; it might start somewhat earlier in Honduras and as early as February in Colombia. Courting adults sing while tossing their heads and flipping their tails back and forth. The clutch size is believed to be two to four eggs, but nothing else is known about the species' breeding biology.<p>The yellow-eared toucanet's song is "a short to long series normally of double notes, 'tik-ett'" that is sometimes accompanied by bill snapping. Pairs sometimes sing simultaneously. It also makes long and short rattles that may be either vocal or made by the tongue inside the bill.

Sharpe's Akalat
Sheppardia sharpei
Small, fairly plain, brown-and-orange robin-like bird. The tail is uniformly rufous-brown and the face shows a pale-gray eyebrow. Found locally in the understory of montane forest. Very shy and inconspicuous. The song is a quick, tripping series of high whistles. Also gives an alternating series of high-pitched piping notes and low-pitched scolding trills. Similar in size, shape, and behavior to Iringa and Usambara Akalats, but distinguished by orange underparts.
Collared Inca
Coeligena torquata
This large, flashy hummingbird is a common resident throughout much of the Andes, where it inhabits lush cloud forest and frequently visits feeders. Note the white breast patch and long, straight bill. The white tail markings really stand out when it flares its tail, which it often does when interacting with other hummers around feeders. Male is darker than female, sometimes almost black, which makes his colorful crown patch more evident. Birds found south of central Peru and north of the Colombia-Venezuela border region are now considered to be separate species, Gould’s Inca and Green Inca respectively.
Blue-throated Mountain-gem
Lampornis clemenciae
Very large for a hummingbird; size alone separates from many other species. Males and females similar: gray below, dusky-greenish back, brown rump, and large dark tail with prominent white corners. Also note white eyebrow and short white mustache stripe. Male has bright blue throat patch, difficult to see unless the light hits it just right. Uncommon in canyons and mountains with mixed pine-oak forests, primarily in Mexico but barely extending into the U.S. Very similar to Amethyst-throated Mountain-gem, especially if you can’t see the throat color. Blue-throated is slightly larger and paler overall with larger white (not gray) tips on the tail feathers; females are plainer, lacking the buffy tones of Amethyst-throated. Also compare with Rivoli’s Hummingbird, especially females; Blue-throated is shorter-billed and plainer (less speckled) on the underparts.
