Purple-chested Hummingbird
Polyerata rosenbergi
Emerald green hummingbird found in humid forest in lowlands and foothills of northwestern Ecuador and western Colombia. Note, especially, the white vent. Male has bluish-purple patch on breast, which is reduced or lacking in female. Both sexes quite similar to Blue-chested hummingbird but can be distinguished by the contrasting white vent. Usually encountered at forest edge or in clearings, and visits feeders in a few places.
分类信息
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 purple-chested hummingbird was moved to the resurrected genus Polyerata.

Mottled Owl
Strix virgata
A common, fairly large owl of tropical lowlands and foothills. Found in forests, woodlands, plantations, gardens, and towns. Roosts during the day at all levels in dense cover of taller trees, but at night it often hunts from low perches such as fence posts and road signs. Note the rounded head, brown eyes framed with whitish crescents on either side of the bill, and overall brown plumage that is streaked below. Varied gruff hoots can suggest a dog barking.
Brown-headed Honeyeater
Melithreptus brevirostris
Small honeyeater with brown cap. Primarily gray-brown with olive back and lighter underparts. Eye patch and band leading from the eye to back of the head are cream-colored. Juveniles have pale blue coloration around the eye and a yellow bill. Take care to separate from juvenile White-naped Honeyeater, which lacks the pale half collar around the side of the neck. The plumage of this species varies geographically. Common in eucalypt forests, where it is usually very vocal and active. Forages in small groups.
Plaintive Cuckoo
Cacomantis merulinus
A small and slender cuckoo, far more often heard than seen; the male's accelerating song, which decreases in volume as it progresses, is composed of a few whistled long notes followed by shorter, breathy notes. Adult male and typical (non-hepatic) female show orange belly, gray head, and brown back and tail. Hepatic, or rufous-morph, individuals are rusty brown above and white below, with black barring all over the body. Inhabits open woodlands, edges, and agricultural areas.
