Masked Flowerpiercer
Diglossa cyanea
Fairly large flowerpiercer, almost all blue with black mask and red eye. Bill is upturned with a hook at the tip, typical of a flowerpiercer. Sexes alike. Fairly active like a warbler or small tanager, often following a mixed-species flock but sometimes foraging separately. Could be confused with Blue-and-black Tanager but note bill shape and blue (not black) wings. Separated from other flowerpiercers by bright blue color combined with black mask. Quite common and widespread in the Andes from Venezuela to Bolivia, usually above 2,000 m. Feeds on fruit, nectar, and insects.
识别特征
The masked flowerpiercer grows to a length of about 15 cm (6 in). The adult male is deep ultramarine blue with a dark mask. The beak is large, black, and upturned, with a characteristic hook on the tip of the upper mandible. The iris is bright red. The female is similar in appearance but altogether duller. The juvenile has a reddish-brown iris. At the northern end of its range, the song is a series of reedlike notes terminating in a twitter, while at the southern end, it is a jangling series of high-pitched notes ending with several lengthy "tseee" notes. These differing songs suggest that the northerly and southerly populations may be different species.

分布与栖息地
The masked flowerpiercer is endemic to the Andes in South America where its range extends from Venezuela and Colombia, through Ecuador and Peru to Bolivia. It inhabits montane forest, cloud forest, secondary forest, scrubby woodland and forest edges, at altitudes between about 2,000 and 3,500 m (6,600 and 11,500 ft).

行为
This bird is often seen in small groups or mixed flocks, foraging through the foliage for insects and fruit, and probing into flowers with its beak. The flowers of the small tree Axinaea sclerophylla are pollinated by birds, the pollen being liberated in a puff when the stamens are manipulated. During a research study, the only bird seen visiting the flowers was the masked flowerpiercer, which proceeded to pull off and consume the stamens, one at a time.<p>Breeding takes place between June and September in Colombia, but in other parts of the range, juveniles have been seen at various times of year. The nest is a cup-shaped construction, built in a bush, and composed of mosses and dry grasses and lined with feathers. The eggs are pale bluish-green blotched and speckled with reddish-brown.

African Penduline-Tit
Anthoscopus caroli
Tiny, nondescript, gray bird with a small, sharp bill. Most notable for its lack of distinct marks or coloration! The underparts vary geographically, from whitish to rich buff. Found in savanna and broadleaved woodland. Usually in small, active flocks. Most common vocalization is a series of high-pitched “tsu-tsu-tsii” triplets. Similar to Mouse-colored and Southern penduline-tits, but paler below and browner above than Mouse-colored, and lacks the black facial marks of Southern.
Purple-crested Turaco
Gallirex porphyreolophus
A bulky, iridescent bird clad in deep purple, blue, green, and olive washed with pink. It clambers acrobatically through riverine woodland and savanna thickets. In flight it explodes from the canopy with distinctive deep red panels in the wings. It produces a distinctive croaking “khoh-khoh-khoh-khoh….” that gets progressively louder before suddenly stopping. The similar Ross’s Turaco differs from Purple-crested Turaco by being darker overall and having a red crest and yellow face.
Gray-throated Barbet
Gymnobucco bonapartei
Dark, chunky barbet with an odd tuft of feathers on its forehead. The eye is pale in the eastern part of the range and dark in the west. Usually in small groups on and around dead trees in humid forest and secondary growth. The vocalizations include nasal “squeaky toy” calls, “peet” notes, and a dry rattle. Similar to Naked-faced and Bristle-nosed Barbets, but has a mostly feathered head and a dark bill. Sladen’s Barbet also has a dark bill, but Gray-throated is separated from that species by its feathered head.
