Description
The Talamanca hummingbird is about long. Males weigh about and females . Both sexes have a long straight black bill and a small white spot behind the eye.[Partida-Lara, R. and P. L. Enríquez (2020). Talamanca Hummingbird (''Eugenes spectabilis''), version 1.0. In Birds of the World (T. S. Schulenberg, Editor).

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.

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.][

Behavior
Movement
The Talamanca hummingbird is generally sedentary, but some individuals move to lower elevations in what might be a regular migration.[
]
Feeding
Talamanca hummingbirds feed on nectar from a variety of flowering plants, though the full list of sources has not been defined. Males defend flower patches in the lower storeys of the forest and sometimes also feed in the canopy. Females forage by trap-lining
In ethology and behavioral ecology, trap-lining or traplining is a feeding strategy in which an individual visits food sources on a regular, repeatable sequence, much as trappers check their lines of traps. Traplining is usually seen in species ...

s though details are lacking; the closely related Rivoli's hummingbird captures them in mid-air or by gleaning from vegetation while hovering.[
]
Breeding
The Talamanca hummingbird's breeding season in Costa Rica spans from November to March; it has not been defined in Panama. It builds a cup nest of plant down and other fine fibers and covers the outside with moss and lichens. The nest is typically placed at the tip of a dangling bamboo stem between above the ground. The incubation period is not known; the time from hatch to fledging is at least 25 days.[
]
Vocalization
The Talamanca hummingbird's song is "a soft, low-pitched song of burbling, scratchy, buzzy notes." It makes "a rapid stream of high, clear, liquid chips" during aggressive encounters. Another call is "a rather guttural, rolling ''nrrt'' or ''drrk''."[

follows HBW taxonomy and so treats Rivoli's and Talamanca hummingbirds as a single species assessed as being of Least Concern. As a whole it has a large range and an apparently stable population, though the population size is not known.[ The Talamanca hummingbird is considered fairly common throughout its range. However, it "is vulnerable to habitat loss and degradation, although ample forest remains in the Cordillera de Talamanca."][
