Hooded Treepie

Chunky medium-sized parrot with a long tail, bright green plumage with slightly yellower underparts, and a red forehead and eyeline. Some blue in the flight feathers most visible in flight. Uncommon and local; found in remnant patches of higher-quality habitat and often encountered feeding on the seeds of casuarinas. Calls relatively high-pitched and nasal, higher-pitched than the calls of Horned Parakeet.

Handsome blue-and-black jay of tropical forests, woodlands, and gardens endemic to west Mexico. Usually in small groups, which can be noisy and conspicuous or very quiet and easily overlooked; often with Yellow-winged Caciques. Around the town of San Blas (in Nayarit, Mexico), appreciably larger Purplish-backed Jay occurs at southern end of its range (and northern end of San Blas Jay’s range). Purplish-backed is deep purplish blue on back and tail, not strikingly two-toned blue-and-black like San Blas Jay, and has bright yellow legs. Voices also very different. Purplish-backed occurs in mangroves and adjacent woodlands in and around town while San Blas Jay occurs in foothill forest of coffee plantations south of town.

Dull, relatively unmarked olive-brown warbler with a prominent yellowish-white eyestripe, faint wingbars, and pale whitish underparts. Visually inseparable from Japanese and Kamchatka Leaf Warblers; listen for song, an electric chattery trill. Also gives a metallic two-noted call and a short harsh buzz. Breeds in shrubby areas, often near water, throughout the Eurasian taiga. Breeding range extends to Alaska, where it is the only leaf warbler. Winters in lowland and foothill forest, forest edge, and gardens, primarily in Southeast Asia.
