Geoffroy's Daggerbill
Schistes geoffroyi
Fairly small hummingbird found on the east slope of the Andes from Venezuela to Peru. Both sexes mostly green with short, straight bill. Males have green throat, blue patches on neck sides, and a broken white collar. Females has duller greenish throat and whitish eyeline. Inconspicuous; look for singles at flower patches in understory of foothill and subtropical forest and edge, from around 800-2,000 m.
Identification
Geoffroy's daggerbill is 8.6 to 9.3 cm (3.4 to 3.7 in) long and weighs 3.5 to 4.1 g (0.12 to 0.14 oz). It gets its name from the tip of its bill, which is very narrow and sharply pointed, though this characteristic is not easily seen in the field. Males of the nominate subspecies have bronzy green upperparts with a coppery cast to the rump. They have glittery violet patches on the sides of the iridescent golden-green throat, white patches on either side of the upper chest, and an elongated white patch behind the eye. Their underpars are green. Females' throats are white with green speckles but they are otherwise like the male. S. g. chapmani is similar to the nominate but has no white patches on the throat.
Taxonomy
Geoffroy's daggerbill has often been considered conspecific with what is now the only other member of its genus, the white-throated daggerbill (S. albogularis), under the name "wedge-billed hummingbird". The South American Classification Committee (SACC) of the American Ornithological Society split them in June 2018 and the International Ornithological Committee (IOC), the Clements taxonomy, and BirdLife International's Handbook of the Birds of the World (HBW) followed suit. Later all of them except HBW adopted the "daggerbill" English name; HBW uses the name "eastern wedge-billed hummingbird". Some authors have suggested that the genus be merged into that of the visorbearers, Augastes. <p>Geoffroy's daggerbill has two subspecies, the nominate S. g. geoffroyi and S. g. chapmani.

Range and habitat
The nominate subspecies of Geoffroy's daggerbill is found from the Sierra de Perijá and Coastal Range of Venezuela south along the Andes through eastern Colombia and eastern Ecuador into Peru as far as Cuzco. S. g. chapmani is found from Cuzco into central Bolivia. The species inhabits the interior and edges of dense cloudforest. In elevation it usually ranges between 900 and 2,300 m (3,000 and 7,500 ft) and has been recorded as high as 2,500 m (8,200 ft) in Ecuador and 2,800 m (9,200 ft) in southeastern Peru.

Behavior
Geoffroy's daggerbill is mostly sedentary but makes some elevational dispersion after the breeding season.<p>Geoffroy's daggerbill forages in dense vegetation from near the ground to medium heights. It collects nectar from tubular flowers of a variety of shrubs, vines, and small trees. It also captures small insects on the wing or sometimes by gleaning from vegetation.<p>The breeding season of Geoffroy's daggerbill spans from August to November in Venezuela but has not been defined elsewhere. It builds a cup-shaped nest of soft seed fibers and spider silk decorated with lichens on its outer wall. The clutch size is two eggs. Incubation, by the female alone, lasts 15 to 16 days with fledging 20 to 22 days after hatch.<p>The song of Geoffroy's daggerbill is "an insect-like series of regularly spaced simple 'tsit' or sibilant 'sink' notes." It is sung from a low perch.

Other Birds
Chimango Caracara
Daptrius chimango
Noisy, conspicuous, and often a common scavenger in habitats ranging from towns and cities to open forest, farmland, and beaches; ecological counterpart to crows. Often in groups, locally of tens or even hundreds, feeding on the ground or tumbling and sailing with agile flight; often chases and mobs larger raptors. Plumage brownish overall, often with gingery tones, and with variable paler dappling above and fine barring below. Bold creamy white wing panels and tail base striking in flight.
Sangihe Whistler
Coracornis sanghirensis
A chunky, dingy-looking, thick-billed songbird. Upperparts dark olive-brown, with a grayish head and a pale buff wash on the underparts. Note the pale bill with a dark tip. A rare species confined to canopy of tall, mature hill forest on Sangihe Island at sites where this habitat persists on ridges. Typically encountered in small groups or pairs. Most similar to Sangihe Golden-Bulbul, but Sangihe Whistler has a bicolored bill and lacks a yellow throat and face. Its loud song consists of around four repeated phrases. Also gives “churr” and sharp “wit” calls.
Orangequit
Euneornis campestris
A small inhabitant of moist woodlands where it feeds on nectar and fruit. Note the short and slightly down-curved bill. Males are glossy plumbeous blue with a brick-orange throat but can appear black in poor lighting. Females have a warm brown back that contrasts with a deep gray crown. The Jamaican Euphonia is superficially similar, but has a stubby bill and a greenish back. Vocalizations include a high, thin “tsit-tsit,” with the second note louder and higher in pitch, plus a thin, descending whistled “tsee-uh.”
