Olive-crowned Yellowthroat

Small white parrot with short crest, ring of grayish-blue skin around the eye, and pink patch between the eye and the bill. Yellow-tinged undersides of wings and tail often visible in flight. Endemic to the forests of the Indonesian Tanimbar Islands, where now uncommon and declining. Introduced populations are scattered widely around the world and have become established in suburban areas in Taiwan, Singapore, Puerto Rico, Indonesia's Kai Islands, and Japan.

A poorly known tapaculo found at high elevations near tree line in the northern reaches of Colombia’s western Andes. It was formerly considered a race of the more widespread Paramo Tapaculo. Adult is uniform gray, lacking obvious markings and without the brown coloration found on many other Andean tapaculos. Young birds are brown and heavily barred. Inhabits tangled understory of stunted forest and clumps of small bushes. Song is a long series of buzzy notes that is steady in pace but descends gradually in pitch.

A large and long-tailed shrike with dark gray upperparts, white underparts, a black mask, and white in the wing. The white patches in the black wings and tail are especially conspicuous in flight. Found at high elevations, in open habitats with stunted shrubs such as rhododendron. Descends to lower elevations during the winter. Often uses tall and exposed perches. Vocalizations include harsh rasping notes and more musical, liquid ones. Similar to Chinese Gray Shrike, but larger, with a darker gray back and no white eyebrow.
