The Merida sunangel is 10 to 11 cm (3.9 to 4.3 in) long. It has a straight black bill. The adult male has a pale blue frontlet just above the bill, a dark green crown, and shining green upperparts. The face has black ear coverts. Its throat and upper breast gorget is glittering purple with pinkish scales and has a white pectoral band below it. The rest of the underparts are yellowish to pale buff with round green spots. The central tail feathers are dark green and the outer feathers blackish, occasionally with pale tips.

分布与栖息地
The Merida sunangel is found only in the Andes of Mérida state in northwestern Venezuela. It inhabits rather open landscapes such as shrubby forest edges, openings within forest, and brushy pastures. In elevation it ranges between 2,000 and 3,600 m (6,600 and 11,800 ft).

行为
The Merida sunangel is sedentary.<p>Little is known about the Merida sunangel's feeding habits and diet, but they are believed to essentially the same as those of its close relative, Longuemare's sunangel (H. clarisse). That species feeds on nectar and also includes insects in its diet. It defends feeding territories that are dense with nectar sources. It typically feeds at heights up to 6 m (20 ft), often along streams. It captures insects by hawking from a perch.<p>The only known Merida sunangel nest was found in June. It was a downy cup perched on a small root under an overhang in a road cut. It held two white eggs. Nothing else is known about the species' breeding phenology.<p>The Merida sunangel's call is "a repeated, high-pitched, cricket-like, short trill" that is given both while perched and in flight.

Greater Yellownape
Chrysophlegma flavinucha
Brightly-colored medium-sized woodpecker with a moss-green back, a bright yellow nape, and a powerful pale bill. Gray underparts distinguish this species from the smaller Lesser Yellownape. Males have a white throat or moustache stripe, while females have a dark red one. Gives high-pitched yelps or “kee-eep!” notes. Found in various forested areas, but most common in hilly and montane areas; not a woodpecker of small parks and cities. Forages on trunks and along branches in pairs and flocks, both single- and mixed-species.
White-collared Jay
Cyanolyca viridicyanus
Handsome small jay of montane Andean forest. Slender and long-tailed, without a crest; overall dark blue with a black face and throat, thin white eyebrow, and white chest arc. Forages at mid-height in mossy forest, often in pairs or small groups. Listen for its repeating whistled call and harsher nasal calls.
Oriental Skylark
Alauda gulgula
Chunky brown songbird with a weak crest, typically found on the ground in open fields and meadows. Darker above than below, with fine black streaking on the chest and light chestnut ear coverts with dark border. Very similar to Eurasian Skylark, with which it shares much of its range, but Oriental has buffy, not white, outer tail edges and trailing edge of wing. Breeding males “skylark,” singing a series of variable notes while hovering high above the territory.
