Little Swift

Apus affinis

Small swift with a square-tipped tail, broad outer wings and sharply-demarcated white rump. White on the rump extends to the sides and is visible from below. Note the obvious contrasting white throat. Superficially similar to house-martins, but lacks a white belly. Breeds both in natural cliff settings and in urban areas where it nests on buildings. Very vocal, particularly near the nest, giving a constant descending trill.

识别特征

Little swifts are readily identified by their small size. Their wingspan is only 33 cm compared to 42 cm in the case of common swift. Their plumage is black except for a white throat and rump, the white rump patch extending onto the flanks. They have a short square tail, with all rectrices round-tipped. The flight is fluttering like that of a house martin, and the call is a high twittering. Like other swifts they are very short-legged. The legs are used for clinging to vertical surfaces only.

Bounty Islands Shag

Bounty Islands Shag

Leucocarbo ranfurlyi

A large pink-footed marine shag endemic to the Bounty Islands and surrounding coastal seas. Adults are black above with a blue sheen, white below, with white patches on upper wings visible in flight. Slim hooked bill is a faded brown or pink. Orange-yellow skin at the base of bill and gape, circling the eye, brightens during breeding along with a red-orange gular pouch. A single crest is developed during breeding season. Juveniles have brown rather than black on the upperparts and pale facial skin. No other shags have been recorded on the Bounty Islands.

Monk Parakeet

Monk Parakeet

Myiopsitta monachus

Medium-sized parakeet, bright lime green above with whitish face and chest, pinkish bill, and blue wingtips. Native to South America, where it is found in various open habitats, especially rural agricultural areas and towns. In introduced range, can be found locally in large cities. Builds enormous stick nests, often on large structures like cell phone towers and power poles; "Cliff Parakeet" of arid southcentral Bolivia manages to build, quite impressively, on sheer cliffs. Listen for its harsh, screeching voice.

Patagonian Mockingbird

Patagonian Mockingbird

Mimus patagonicus

Fairly common in Argentine Patagonia, but local and scarce in southern Chile. Favors semiopen habitats, from shrub-steppe to farmland with hedges and shrubby patches. Often perches atop bushes and on roadside wires and posts. Runs well on the ground, usually with tail cocked; at times can be rather elusive, skulking in bushes. Identified by bold pale eyebrow, buffy-gray underparts, white wingbars, and white tail corners; compare with White-banded Mockingbird, which has much more white in wings and tail.
