22-3-2017 TROGON LODGE, COSTA RICA - TALAMANCA HUMMINGBIRD (Eugenes spectabilis)

The Talamanca hummingbird (Eugenes spectabilis ) is a species of hummingbird in the "mountain gems", tribe Lampornithini in subfamily Trochilinae. It is found in Costa Rica and Panama.

The Talamanca hummingbird is about 13 cm (5.1 in) long. Males weigh about 10 g (0.35 oz) and females 8.5 g (0.30 oz). Both sexes have a long straight black bill and a small white spot behind the eye.

Adult males have a dull black forehead with a dark green gloss, a metallic violet blue to purple crown, and a dull black nape and upper back. Much of the rest of the face is dark green, and the lores are a deep black. The rest of the upperparts and the tail are bronzy green to golden green; the tail feathers sometimes have grayish tips. The chin and gorget are metallic bluish green. The breast and belly are dark bronzy green, on the belly mixed with brownish gray. The undertail coverts are dull bronzy green with pale buff edges.

Adult females do not have the iridescent crown and gorget of the male. Their upperparts are dull dark green and most of the face is sooty black. The two innermost pairs of tail feathers are also dull dark green and the three outer pairs bronzy green with a black band near the end and brownish gray tips. The throat is brownish gray with buff tips to the feathers, the flanks dark green, and the breast, belly, and undertail coverts dull brownish gray with a dull green wash.

Immature birds are similar to the adult female, but have darker brown underparts with a dull buff scaly appearance. The upperparts' feathers, especially those of the crown and neck, have buffy fringes.

The Talamanca hummingbird is generally sedentary, but some individuals move to lower elevations in what might be a regular migration.

The Talamanca hummingbird is found in mountains from central Costa Rica into western Panama. In Costa Rica it occurs in the Cordillera Central and Cordillera de Talamanca and in Panama only in the Volcán Barú massif of Chiriquí Province. It inhabits oak forests and is partial to the forest's edges and clearings, and also is found in nearby secondary forest. In Costa Rica it occurs from 2,000 m (6,600 ft) up to treeline but is most common above 2,500 m (8,200 ft) and is occasionally found as low as 1,850 m (6,100 ft). In Panama it occurs between 2,000 and 2,400 m (6,600 and 7,900 ft).
