Fawn-breasted Tanager
Pipraeidea melanonota
Small sleek tanager with distinctive color pattern: pale sandy underparts with peachy blush on breast, black mask, powdery-blue crown, and darker blue back and wings. Sexes alike. Uncommon in second growth, edges, and gardens, where it is most often seen singly or in pairs. Occasionally follows mixed-species flocks. Found from foothills to upper subtropical zone in Andes, sometimes straying even higher. Populations in southeastern South America occur at lower elevations.
识别特征
The fawn-breasted tanager has an average body length of 14 cm (5.5 in) and can weigh 18–25 g (0.63–0.88 oz). This species of tanager has an unusually short, wide beak, similar to the beaks of swallows, as well as short legs and tail, and long wings. The most noticeable coloration of this species is its sky-blue crown and broad black mask that extends over the eyes into ear-coverts. The coloration of male crown and nape is a medium blue, and the forehead, lores, ocular area and ear-coverts are deep black. The mantle and back of males are a dull blue color, the lower back and rump a bright turquoise-blue, tail dusky blue, throat and the underparts of the body are a cinnamon color. The iris is a dark red to reddish-brown color, and the bill is dusky with a lower mandible that is normally grey. The female has a similar coloration but is usually duller, particularly in the crown region, and with a brownish coloration on the back. Juveniles are almost without pattern and have a dull brownish-grey coloring. The fawn-breasted tanager is usually seen singly or in pairs, most often in the semi-open, but it may perch at any height.<p>Calls consist of "see" or "swee" tones varying in sets of 4 or 5 notes sung slowly, or a higher number of notes, around a dozen, uttered in a pulsating trill pattern in a faster rhythm.
分类信息
The fawn-breasted tanager was described in 1819 by the French ornithologist Louis Pierre Vieillot from a specimen obtained in Brazil. He coined the binomial name Tangara melanonota. The specific name melanonota is from the Ancient Greek melas "black" and nōtos "back". The current genus Pipraeidea was introduced by the English naturalist William John Swainson in 1827. The name combines the genus Pipra which had been introduced by Carl Linnaeus in 1764 with the Ancient Greek eidos meaning "form" or "likeness".<p>Recent DNA evidence places this species as closely related probable relation to the blue-and-yellow tanager.<p>Two subspecies are currently recognized:

分布与栖息地
The range of the fawn-breasted tanager extends throughout South America, covering most of Brazil, Venezuela, Colombia, Peru, Ecuador, Bolivia, east Paraguay, Uruguay, Northeastern Argentina, following towards the southern bank of the Río de la Plata. The species can be found in habitats along forest borders, bushy pastures, and cultivated small semi open areas with large trees and clearings with scattered trees. The elevation range that this species can tolerate varies geographically. In the Andes and Ecuador it can be found at altitudes of 1500–2500 m, with a maximum of 3000 m. In Colombia, it occurs down to 900 m, and in Venezuela to 400 m.

保护状况
The species is currently classified as Least Concern by the IUCN due to its extremely large range, variety of habitats and apparently large population size. Due to opening of forested areas through agriculture and other anthropogenic changes, it may be expanding its range locally.

Versicolored Barbet
Eubucco versicolor
Brightly colored barbet of montane forest. Males are green with a yellow breast, a red belly band, and a red head; the color of the whisker can be blue or yellow depending on the subspecies. Females have a blue face and a greener body. Both sexes have a pale greenish-yellow bill. Often found singly or in pairs with mixed-species flocks, foraging in the mid-story and canopy of humid forest. Listen for a musical purr with a punctuated introductory note: “PA-prrrrr.”
Turquoise-crowned Hummingbird
Cynanthus doubledayi
Brilliantly-colored hummingbird with dark tail and mostly red bill. Fairly common in thorn forest within its limited range. Endemic to Mexico, mainly along the Pacific coast from Guerrero to Oaxaca. Can appear all dark at a distance, but in the right light, male is mostly glistening cobalt blue. Females are less colorful than males, dusky grayish below with prominent pale stripe behind the eye. Similar to Dusky Hummingbird, which occurs on the other side of the Sierra Madre del Sur.
Chestnut-collared Swallow
Petrochelidon rufocollaris
Handsome swallow restricted to relatively dry regions of western Ecuador and western Peru. Plumage is blue and white with chestnut collar, breast band, sides, rump, and forehead. Similar to Cliff Swallow, which is a rare migrant within the range of Chestnut-collared, but note the chestnut breast band and lack of white on the forehead. Most often encountered around cities and towns, where it nests colonially in the eaves of buildings.
