Genovesa Ground-Finch
Geospiza acutirostris
A wedge-billed Galápagos finch found only on Genovesa Island. Formerly considered a subspecies of Sharp-beaked Ground-Finch, and likewise has a sharp, thin bill with nearly straight edges. Bill is black on breeding male and dull orange on female and nonbreeding male. The only other slender-billed finch on Genovesa is the very different Gray Warbler-Finch, which has a thinner bill, tan (not sooty-black) adult male plumage, and paler and less heavily streaked female plumage. Common and easy to see in arid scrub near the coast.

Saffron-crowned Tanager
Tangara xanthocephala
Small tanager found in Andean subtropical zone from Venezuela to Bolivia. Mostly bluish-green with darker wings and streaked back. Head is mostly bright yellow or orange with small black mask, throat, and nape. Buffy undertail coverts and vent only visible at some angles. Sexes alike. A fairly common member of mixed flocks from around 1,200–2,400 m, in cloud forest and edges.

Tahiti Reed Warbler
Acrocephalus caffer
A large, slender warbler with a disproportionately long bill, short wings, and a long tail. Face and eyebrow yellowish-buff with a dark eye-stripe and a pale throat. Upper body and wings mostly dark with pale edges to feathers, giving a messy mottled appearance. Some birds are much paler, often almost entirely white with some mottling. An entirely dark sooty morph occurs. Found in riverine and hillside forest with stands of bamboo up to 600 meters of elevation. Song is a long, slow sequence of warbled phrases and “churr” notes. Calls include harsh churring and “tchak” notes.

Ruff
Calidris pugnax
A bizarre and unique shorebird. Medium-sized with fairly short, slightly drooped bill. Leg color varies from dull greenish to bright orange; bill can be entirely dark or mostly orange. Plumage highly variable, especially breeding males, which have fancy neck ruffs that can be black, white, buffy, reddish-brown, or any combination thereof. Females and nonbreeding birds can be confusing, usually plain grayish-brown overall, sometimes with blotchy markings on the neck and belly. Juveniles are bright buffy with neat scaly patterning on the upperparts. Flight often rather lazy, with deep floppy wingbeats; note white underwings, white sides to rump, and feet projecting well past tail. Males are much larger than females. Breeds in bogs and wet grassy meadows across northern Eurasia; winters mainly in Africa but also across India and Southeast Asia. Migrants occur in almost any wetland habitat, from reservoirs and fields to coastal mudflats. Feeds by probing and picking, often while in shallow water. Rare but regular vagrant to North America, usually single birds found among flocks of yellowlegs.
