Blue-headed Sapphire
Chrysuronia grayi
Striking hummingbird with blue head, shimmering green body, and mostly red bill with black tip. Female duller, grayish below with green spotting on sides of throat. Distinctive in range. Very similar to Humboldt’s Sapphire, which is found at much lower elevations on the coast. Typically inhabits dry scrubby woodland and second growth in high elevation valleys, from 1,200–2,200 m.
Identification
The blue-headed sapphire is 9 to 11 cm (3.5 to 4.3 in) long. Males weigh 6.2 to 6.8 g (0.22 to 0.24 oz) and females 4.6 to 5.6 g (0.16 to 0.20 oz). Males have a straightish coral red bill with a black tip. Females' bills have a black maxilla with red at its base and a mostly pinkish mandible with a black tip. Adult males have a deep glittering blue upper throat, face, and crown. Their nape is dark blue-green and the rest of their upperparts metallic green. Their tail is dark steel blue. Their lower throat, breast, and upper belly are glittering emerald green with a small area of white on the lower belly. Their undertail coverts are metallic green with dark gray edges. Adult females have metallic green to bronze-green upperparts. Their tail's base is dark bronze-green and the rest blue-black with grayish tips on the outer feathers. Their underparts are mostly dull white to grayish white with bronze-green on the sides of the throat and breast and some green flecks on the lower throat. Juvenile males have a dull bluish green face and crown, a bronzy green throat and breast, and a grayish white belly. Juvenile females are similar but duller and more bronzy overall.
Taxonomy
The blue-headed sapphire was formerly placed in the genera Hylocharis and Amazilia. It was moved by most taxonomic systems to Chrysuronia based on the results of a molecular phylogenetic study published in 2014. However, BirdLife International's Handbook of the Birds of the World (HBW) retains it in Amazilia. <p>The blue-headed sapphire is monotypic. However, at one time what is now Humboldt's sapphire (C. humboldtii) was treated as a subspecies of it.

Range and habitat
The blue-headed sapphire is found in inter-Andean valleys from western Colombia's Valle del Cauca Department south into Ecuador's Pichincha Province. It inhabits dry scrublands, the edges of woodland and taller forest, and cultivated areas. In elevation it mostly ranges between about 500 and 2,000 m (1,600 and 6,600 ft) but can be found as high as 2,600 m (8,500 ft).

Behavior
The blue-headed sapphire is reported to make significant seasonal movements but details are lacking.<p>The blue-headed sapphire forages for nectar at a variety of flowering shrubs and trees. It sometimes defends feeding territories, and when several gather at the crown of a flowering tree they are "notably aggressive". In addition to nectar it feeds on insects taken by hawking from a perch or by gleaning from vegetation.<p>Blue-headed sapphires in breeding condition have been noted between November and April. No other information on the species' breeding phenology is known and its nest has not been described.<p>The blue-headed sapphire's song is "a repeated short warbled phrase that starts with a squeaky 'tee' note, 'tee…teetlitlitsee-chup… teetlitlitsee-chup'." It also makes "short 'chip' notes and a high-pitched descending rattle."

Other Birds
Great Blue Turaco
Corythaeola cristata
Wonderful, cartoonish bird. Note the tall black crest and the red-and-yellow bill. The tail pattern is distinctive in flight: note the black bar across the end of the tail and the pale green sides. Found in rainforest, gallery forest, and lush secondary habitat. Usually in small groups. Gives two distinctive calls, sometimes in conjunction: a deep “jeeeow” and a rapid, cackling series of incredibly loud notes.
Black-faced Laughingthrush
Trochalopteron affine
Shy, beautifully patterned laughinghtrush of mid to high elevations. Note bold black-and-white head pattern, golden wing and tail panels, and mostly unmarked brown on the rest of the body. Typically found as pairs during the breeding season and small groups in the winter, in the dense undergrowth of hill and mountain forests. Song like many other laughingthrushes, one to three inflected or quavering whistles. Calls include churring, rattling, and slurred squeaking.
Gray-headed Bullfinch
Pyrrhula erythaca
Striking chubby songbird with a black “robber’s” mask. Male is pearly gray overall with an orange breast patch. Female is warm brown overall and lacks the male’s breast patch. Both sexes have a glossy black tail and wing markings. Breeds in coniferous and mixed montane and foothill forests; sometimes descends to lower elevations during the winter. Song is a chattering series of whistles and distinctly dry and raspingly creaky notes. Calls are soft and mellow-sounding, usually a “poo-yee” or “pooe” note.
