Lazuline Sabrewing
Campylopterus falcatus
Large, distinctive hummingbird. Males have bright blue underparts with maroon tail and downcurved bill. With a quick view, might be confused with a violetear or Green-backed Hillstar, but tail color and entirely blue underparts are distinctive. Females are grayer on the belly with a grayish mustache stripe; note maroon tail. Occurs in the subtropical zone of the Andes from Venezuela to Ecuador. Visits feeders, but also found in forests and edges.

The lazuline sabrewing is about 11.5 to 13 cm (4.5 to 5.1 in) long and weighs 6.4 to 8 g (0.23 to 0.28 oz). Both sexes have a black decurved bill and a white spot behind the eye. Males' upperparts are glittering green that is bluer on the crown. Their throat and breast are glittering dark violet-blue that becomes glittering blue towards the green belly. Their tail is chestnut with wide bronze-green tips on the central pair of feathers. Females' upperparts are like the male's. They have a glittering bluish throat and the rest of their underparts are pale gray with green spots on the flanks.

分布与栖息地
The lazuline sabrewing is found in the mountains of north-central and western Venezuela, the Sierra de Perijá on the Venezuela-Colombia border, the Sierra Nevada de Santa Marta and Eastern Andes of Colombia, and into Ecuador as far south as Napo Province. It inhabits semi-deciduous montane forest, the edges of plantations, the lower reaches of páramo, and gardens. In elevation it generally ranges between 900 and 3,000 m (3,000 and 9,800 ft). In Venezuela it is most common between 1,200 and 2,300 m (3,900 and 7,500 ft) and has been recorded as low as 450 m (1,500 ft) in Colombia.

行为
The lazuline sabrewing is believed to be sedentary.<p>The lazuline sabrewing forages for nectar mostly from the understory to the forest's mid level, usually by trap-lining but sometimes also defending patches of flowers. In addition to nectar, it also feeds on insects captured in the air or gleaned from vegetation.<p>The lazuline sabrewing's breeding season in the Sierra de Perijá appears to include June and in northern Venezuela probably includes October. Nothing else is known about its breeding phenology.<p>The male lazuline sabrewing sings "chik, it, chik, it splek, chat, seet, chik, seet, chik, it, chik, it..., etc., with many variations", usually from a somewhat exposed perch at medium height.

Gray-breasted Woodpecker
Melanerpes hypopolius
Fairly common endemic woodpecker in desert interior habitats of southwest Mexico, especially in areas with tall columnar cacti, including towns and villages. Often in pairs or small groups. Rather drab and grayish overall with a whitish forehead patch and a densely barred black-and-white back. Male has red crown patch and female has plain gray head. No similar species in its limited range.
Malawi Batis
Batis dimorpha
A cute, dumpy, colorful flycatcher-like bird that flits around in the mid-canopy and understory of forest, forest edge, plantations, and gardens. Males have a broad black chest band, yellow-orange eye, white stripe through the top of the wing, and white throat. Females have an orange eye, buff-and-white stripe through the top of the wing, and rufous chin patch. The song is a series of 8-9 plaintive steady piping “peooop” notes, and calls include buzzing grating “ddrz-drrzt-drrr, ddt-ddzt-drzt-drr”. Female Dark Batis is distinguished by its darker (rich rufous rather than white and buff) wing stripe. Male Dark Batis is very similar, but has a slightly longer tail and broader black breast stripe. Also similar to Chinspot Batis, but has darker orange color to the eyes, and female Malawi Batis shows paler rufous on the throat and buff tinges to the wing stripe.
Bright-rumped Yellow-Finch
Sicalis uropygialis
Locally fairly common in the high Andes. Often in flocks, sometimes by the hundreds, and associates readily with other seed-eating birds. Feeds mainly on the ground, often on roadside gravel or in animal corrals. Distinctive in most of range, and distinguished readily from other yellow-finches by combination of silvery-gray cheeks and grayish back and flanks. The namesake bright rump is usually hidden and is a poor field mark. In Chile, Greenish Yellow-Finch occurs mainly at lower elevations.
