Eriocnemis vestita
Medium-sized hummingbird, male mostly green with blue throat and glittering emerald and blue belly. Blue undertail coverts. Females are paler buffy below with a speckled appearance. Both sexes have conspicuous large white puffs at base of legs, much larger than Buff-tailed Coronet’s white puffs. Found in the temperate zone of the Andes, where they most often occur at the forest edge.

The glowing puffleg is 9 to 10 cm (3.5 to 3.9 in) long. Males weigh 3.3 to 7.2 g (0.12 to 0.25 oz) and females 3.6 to 5.3 g (0.13 to 0.19 oz). It has a straight blackish bill. The nominate subspecies' male has shining dark green upperparts with a golden green rump and uppertail coverts. It has a glittering purple throat patch thinly surrounded by golden green. The rest of its throat and its upper breast are shining blackish green, its belly glittering golden green, and its undertail coverts iridescent purplish blue. Its leg puffs are white. The tail is forked and dark steel blue. The female has shining golden green upperparts. Its throat patch is a few bluish purple discs on a buffy background. The rest of the throat and the breast are buff and the belly grayish white, all with golden green discs. The juvenile is similar to the female.<p>Subspecies E. v. paramillo is like the nominate but without the golden green fringe to the purple throat. Males of E. v. smaragdinipectus have the largest purple throat patch of all. E. v. arcosae is similar to smaragdinipectus but its rump and uppertail coverts are yellowish green that extends up into the lower back; males also have shorter bills and a grayer belly than the nominate.

分布与栖息地
The subspecies of glowing puffleg are found thus: <p>The glowing puffleg inhabits a variety of fairly open landscapes. The edges of cloudforest and elfin forest predominate. It also occurs on brushy slopes, overgrown pastures, and páramo and occasionally in denser subtropical forest. In elevation it ranges between 2,300 and 4,200 m (7,500 and 13,800 ft) but mostly occurs between 2,800 and 3,500 m (9,200 and 11,500 ft).

行为
The glowing puffleg is sedentary.<p>The glowing puffleg feeds on nectar, usually at the flowers of low-growing shrubs with short corollas. It nectars while hovering, perching, or sometimes clinging to the flower. It is "pugnacious and territorial" at flowering plants. Its diet also includes insects and spiders taken by hawking.<p>The glowing puffleg's breeding season is not well defined. At least in Colombia's Eastern Andes it appears to have nested in every month except July. The nest has not been described except that it is often built in stands of grass. The female incubates the two white eggs; the incubation period and time to fledging are not known.<p>The glowing puffleg's only described vocalization is "a single metallic note 'tseek' or doubled 'tsi-tseek', repeated at irregular intervals". It is given both from a perch and while hovering.

South Island Robin
Petroica australis
A small charcoal-colored songbird endemic to New Zealand. Confined to the South and Stewart Islands. Favors native and exotic forest stands. Males have a more distinct separation between dark gray and cream on their chest than females. Juveniles mirror the look of a female but with less to no cream underneath. Can be incredibly confiding and curious about humans. It is possible to bring individuals out into the open by disturbing leaf litter and then sitting quietly. Actively flushes out prey with foot trembling and by flicking its wings and tail. Male song is a loud and simple phrase of notes including “pwee-pwee-pwee.”
