Blue-crowned Lorikeet
Vini australis
A mostly green lorikeet with a relatively rounded tail and bright orange bill and feet. Bright blue crown and large red throat patch are diagnostic. Widespread through most habitats, but nomadic, often traveling between islands in search of food. Unique within its range. Vocally distinctive, with a common high-pitched “seeEEE” call. Interaction calls are more complex reels of squeaking and squealing.

The blue-crowned lorikeet was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus australis. Gmelin based his description on the "Blue crested parrakeet" that had been described in 1781 by the English ornithologist John Latham in his A General Synopsis of Birds. Latham believed that his specimen had come from Hawaii (Sandwich Islands) but this was an error; the specimen had come from the Samoan Islands. The blue-crowned lorikeet is now placed in the genus Vini that was introduced in 1833 by the French naturalist René Lesson. The genus name is the Tahitian word for a local bird.<p>It is still common, but declining on some islands, apparently from predation by rats. They frequent areas with flowering trees, including coconut plantations and gardens, usually in small flocks of less than about 15 individuals or in pairs during breeding season. It eats nectar, pollen and soft fruits, especially wild hibiscus and coconut. The blue-crowned lory nests in holes in trees, but may also dig burrows in earth banks.

Bonin White-eye
Apalopteron familiare
Unique and unmistakable inhabitant of the central and southern Ogasawara (Bonin) Islands. Gray-olive with a yellow head and strange triangular black mask. Found in a range of different habitats on the Ogasawaras, from remnant native vegetation to cultivated gardens. Feeds on the ground and at all levels of vegetation, often in pairs or small flocks. Gives sweet “deeeyu” and sharp metallic squeaks, amongst other vocalizations.
West Himalayan Bush Warbler
Locustella kashmirensis
A small, brownish bird with a thick, rounded tail. Note the black bill, the gray underparts, and the contrasting darker gray sides of the breast. The buff-breasted morph is less common and lacks any gray. Inhabits alpine scrub in the summer. Possibly winters lower down in the plains. The song consists of short clicks and buzzes. Extremely similar to Spotted Bush Warbler; the West Himalayan Bush Warbler is slightly paler, but best told apart by range and song.
Tamaulipas Crow
Corvus imparatus
Small glossy crow, common in northeast Mexico. Occurs in towns, villages, rubbish dumps, farmland, and semiopen areas with hedges and taller trees. Social and usually in flocks, at times of hundreds. Most likely to be confused with male Great-tailed Grackle, which has pale eyes and longer and keel-shaped tail (shed in late-summer molt). Chihuahuan Raven much larger, with much heavier bill and different voice. Calls of Tamaulipas Crow are low, froglike croaks.
