Rufous-crowned Prinia

A large, all-dark gadfly petrel found across the Tasman Sea and the temperate and subtropical southwest Pacific Ocean. Note the gray face, chin, and throat and the stout bill. Wings long and narrow. In New Zealand, breeds on offshore islands off the North Island as well as on some mainland cliffs and headlands near the sea. Gives an “o-hi” or “o-hoe” call when flying above breeding areas or a loud “si-si-si” when on land or in burrows. Other dark gadfly petrels are rare off the New Zealand mainland but the similar Providence and dark-morph Kermadec Petrels have white patches on the underwing; the latter also lacks any gray on its face. The rarely-seen Kerguelen Petrel is smaller, with a shorter bill and a pale edge on the underwing.

Uncommon swallow in montane forest in the Andes from Venezuela to Bolivia. Similar to the more common Blue-and-white Swallow, but look for the buffy throat and browner flanks on Pale-footed Swallow. Found in flocks, usually not far from forest. Not frequently found around human settlements unlike Blue-and-white Swallow. Occurs from around 2,400–3,200 m.

Handsome spinetail with a highly restricted range, known only from arid Andean valleys southeast of the city of Cajamarca in northern Peru. It has a white throat and eyebrow, a streaky breast, and chestnut wings and tail. Plumage is similar to Necklaced Spinetail, but Great is much larger, and the two species do not overlap. Inhabits thorny scrub and cacti. Vocalizations include fast rattles and shrill, doubled chirps.
