Blood-colored Woodpecker
Dryobates sanguineus
Small woodpecker of coastal forests, including mangroves, overgrown plantations, and urban areas. Unmistakable in its limited range. In all plumages note red back and heavy barring below. Often occurs in pairs. Climbs tree trunks and woody vines, boring into decaying wood for insect prey; may also forage in bromeliads and other arboreal plants. Can be noisy in aggressive interactions; gives various sharp calls similar to other small woodpeckers.

分布与栖息地
Though some sources say that the blood-colored woodpecker is found in "the Guianas", the South American Classification Committee of the American Ornithological Society has records only in Guyana and Surinam, and not French Guiana. It is a bird of the coastal lowlands, where it inhabits mangroves, swamp forest, and sometimes coffee plantations.

Kea
Nestor notabilis
The world's only true alpine parrot, found only on the South Island of New Zealand. Large, with olive-green plumage. Note scarlet underwings visible in flight. Females are smaller than males with shorter bills. Juveniles have a yellow eye-ring and a paler crown. Gives a distinct loud “keee-aaa” call, mostly in flight. Very inquisitive toward people and their cars within the mountain ranges, at ski fields, at huts, and along mountain roads. Distinguished from New Zealand Kaka by blue-green flight feathers, larger size, and alpine habitat.
Nazca Booby
Sula granti
Large seabird, very similar to Masked Booby. Long and pointy on all ends: wings, tail, and bill. Adults mostly gleaming white with black flight feathers and face; note pinkish-orange (not yellow) bill to help separate from adult Masked. Young birds darker overall with brown head contrasting with white belly and dirty brown markings on underwings; very similar to young Masked or even adult Brown Booby. Found in the Pacific Ocean from Mexico to Peru where it feeds on fish; breeds on rocky islands, especially the Galapagos.
Streak-throated Hermit
Phaethornis rupurumii
Drab hummingbird with a white tipped tail found in northern South America, ranging west as far as eastern Colombia. Like other hermits, it has a dark mask bordered by buffy stripes and a long bill. The blurry dark streaks on its throat and breast help to separate it from other similar species. These streaks are variable, and on adult males they nearly form a solid dark patch, but females and young birds may only show a few small blotches. Found in a variety of habitats including seasonally flooded rainforest along the Amazon and drier and scrubbier forest in hilly terrain. Uncommon to rare in most of its range.
