Abyssinian Owl

Large dark swift with long sickle-shaped wings and a forked tail, which is often kept closed in a needle-tipped point while in flight. Black overall with an ashy gray throat and a thin white rump. Distinguished from needletails by proportionally longer wings, longer and more slender body, and much longer tail. Closely related Pacific Swift has a broader and brighter rump patch and a whiter throat. Faint greenish gloss on the back is diagnostic but difficult to see. Like other "fork-tailed swifts", usually seen in flight over hills, forests, and open areas. Gives high thin notes as well as a grating trills. Breeds in limestone caves.

A large heavily built duck that is uncommon to fairly common along rocky seacoasts; not found on lakes, unlike Flying Steamer-Duck. Both sexes are steely blue-gray overall, brighter than Flying Steamer-Duck, with a stouter and deeper-based bill. The bill of both male and female is bright orange in the southern parts of its range, but is orange with a greenish distal patch around Chiloé Island (likely a different species). The bill of juvenile birds is duller grayish to dull yellowish; attains adult color by winter.

A medium-sized weaver with a long, relatively slim bill. Male is mostly bright yellow with an orange throat and black lores. The female is much duller, greenish-yellow with a white belly. The eye color of both sexes can be whitish or red, and the bill can be mostly pinkish or black. A colonial nester that is found around wetlands, including lakes, rivers, and swamps. Similar to Holub’s Golden-Weaver, but smaller and slimmer-billed. Female can be confused with several other female and non-breeding male weavers, but is usually found in association with the more distinctive males. Vocalizations are typical of weavers: “chet” notes and a sizzling “radio static” song.
