Blue-chested Hummingbird
Polyerata amabilis
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 forest edge or shrubby second growth. Nearly identical to Charming Hummingbird but no range overlap.
识别特征
The blue-chested hummingbird (Polyerata amabilis) is a species of hummingbird in the family Trochilidae. It is found in Colombia, Costa Rica, Ecuador, Nicaragua, and Panama. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest. The hummingbird feeds by trap-lining and also defends feeding territory (particularly in nectar-poor habitat), taking nectar and also small insects gleaned from foliage. These foraging territories are often on the borders of forests in areas of scattered flowers. The males will form leks to try to gain the attention of females during breeding season. 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 blue-chested hummingbird was moved to the resurrected genus Polyerata.

Rusty-crowned Ground-Sparrow
Melozone kieneri
Attractive, rather skulking large sparrow of foothills, endemic to west Mexico. Favors brushy understory of tropical woodlands, shade-coffee plantations, and brushy hedges in farmland. Mostly stays well hidden on or near the ground, but can feed in the open beside quiet roads and trails, especially in early mornings; usually in pairs. Note the rusty cap (often raised when excited), white spectacles, and extensive white bib with a dark central spot.
Rifleman
Acanthisitta chloris
New Zealand’s smallest bird. Tiny endemic wren with fragmented distribution across both islands. Often found in patches of mature forest and scrub. Constantly moving across tree trunks and within the canopy. More common in higher-altitude beech forest. Males are smaller, with bright green on the head and back. Females are mainly yellowish-brown. Note the short wings, the stumpy tail, and the slender, upturned black bill. Utters an almost constant high-frequency “zipt,” “pip,” or “chuck” calls while foraging that are often inaudible to people. Distinguished from South Island Wren by smaller size and shorter legs; rarely feeds on forest floor. Habitats unlikely to overlap.
Verdin
Auriparus flaviceps
Tiny, unique songbird with a sharply pointed bill. Mostly plain gray with a yellow head. Small rufous patch on shoulders is sometimes visible. Juveniles lack the yellow head; note bill shape to help separate from Lucy's Warbler or Bushtit. Forages solo or in pairs in scrubby arid habitats, especially mesquite. Occasionally visits hummingbird feeders for nectar; primarily feeds on insects.
