Blackish Cuckooshrike

Warm brownish songbird of shrubby forest edges, reedbeds, and gardens. Brown above, pale below, with pale supercilium and dark eyeline. Note rufous crown. Shy and skulking, rarely straying from dense undergrowth even when singing. Usually detected by its song, a long mournful whistle followed by a quick burst of rich, bubbly notes. All but indistinguishable from Japanese Bush Warbler; averages slightly more rufous on the crown, but best identified by range and voice.

Unique and spectacular hummingbird of the upper humid montane forest in Bolivia. Plumage mostly black, with striking white feathers on breast and a shining blue rump. Occurs to, and sometimes just above, treeline on the east side of the Andes from western Santa Cruz department to La Paz. The only black hummingbird in its range. This species is generally patchily distributed, but can be locally common, especially where flowers are abundant.

Small songbird, a member of the Arctic Warbler complex, this species looks essentially identical to Arctic Warbler and Kamchatka Leaf Warbler but is more evenly yellowish. Normally only distinguished in the field by breeding range and song: breeds in forests on all of the main Japanese islands except Hokkaido, where it is replaced in summer by Kamchatka Leaf Warbler. Favors foothill to montane areas with dense brushy understory; can be found in more open wooded habitats in migration and on wintering grounds. Song resembles that of Arctic in general pitch and register but is less uniform, like a more rising and falling version of Arctic’s song. Call also similar but averages lower in pitch.
