Yellow-crowned Euphonia

Australian crows and ravens are challenging to identify; concentrate on call, throat-hackles, behavior, and location. Calls typically end with a very long, drawn-out wail. The very long throat hackles lend it a bulbous-bearded appearance. Inhabits many habitats in southwestern Western Australia and much of eastern Australia. Essentially the default crow/raven in Sydney and Perth.

Beautiful toucan of Andean cloud forest that is found mainly in Bolivia, though it also reaches far southeastern Peru. Very colorful, with greenish wings, mostly blue underparts, an azure collar, and a yellow bill with a black tip and black spot near the base. It occurs south of the range of Gray-breasted Mountain-Toucan, which has a very different bill pattern. Typically encountered in pairs or small groups in the forest canopy, where it sometimes gives rising squeals, short yaps, and harsh rattles.

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.
