Charming Hummingbird
Polyerata decora
Nearly identical to Blue-chested Hummingbird but no range overlap. Male has glittering purple-blue throat, green back and crown, paler grayish belly, and dark tail. Female less obvious, with spotted chest; note the pink base to the lower mandible of the bill. She is smaller than most other female hummingbirds that have spotted chests, such as White-necked Jacobin. Usually seen fairly low at a forest edge or shrubby second growth.
识别特征
The charming hummingbird (Polyerata decora) and also known as the beryl-crowned hummingbird is a species of hummingbird in the family Trochilidae, found in Costa Rica and Panama. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest. Staying within the exterior of forests, it searches for scattered flowers and various arthropods for food. Due to its longer beak and wings, and slight coloring differences, it has been placed in its own species separate from the blue-chested hummingbird. Leks of up to 12 male birds will sing together in hopes of attracting a mate. This species was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the charming hummingbird was moved to the resurrected genus Polyerata.

African Golden Oriole

Similar to Eurasian Golden Oriole, but the wing feathers have yellow edging, and the black face mask extends well behind the eye.

Most similar to Ruddy Pigeon but plumage grayer (not reddish) and eye paler. Usually quite secretive, staying in the canopy where singles or pairs feed on fruits. Found from lowlands into subtropical zone, up to 2,300 m (7,500 ft). More often heard than seen; listen for the cooing “who-cooks-for-you” song with the last two notes drawn out.
