White-rumped Spinetail
Zoonavena sylvatica
A small swift with short square tail (rounded when spread), a relatively large head, black upperparts, and a white rump patch. It has a distinctive wing shape with a hooked outer wing and a bulging mid-wing that is pinched at the base. Underparts grade from a brown-gray throat to a pure white belly without any sharp demarcation. Spines on the tail are minute and hard to discern in the field. Flight action, with rapid wingbeats and short glides, is different from that of Little Swift. Mostly seen in flocks, sticking to woodlands and hills, though it descends to the adjoining plains just after showers.

Rufous-tailed Robin
Larvivora sibilans
Combination of strongly scaled breast, rufous tail, and round-headed appearance distinguish this species from others in its range. Small and skulky, sticking to dense shrubbery and shorter trees in its forest breeding grounds, where it favors dense, moist growth in lowland broadleaf forests. Often bolder on migration, emerging into forest edges and gardens. Song is distinctive, a long, wet-sounding descending trill.
Akekee
Loxops caeruleirostris
A small, very rare Hawaiian honeycreeper of remote native forests on Kauai. Declining rapidly; found only above 4,000 feet elevation in the eastern ‘Alaka’i Plateau. Males are yellow with a small black mask and females are greenish. The crossed bill that is uses to pry open leaf buds in search of insects and larvae is difficult to see. The longer tail with a notched tip distinguishes it from other small honeycreepers. Its rarely-heard song is a wavering trill that changes in speed and pitch. Call is a soft upslurred “suweet.”
Cape Robin-Chat
Dessonornis caffer
Pretty robin-chat with a short white eyebrow and a rufous chest. This is the only robin-chat with a gray belly. The outer tail feathers are orange, which can be conspicuous in flight. Found in many different habitats, including fynbos, scrub, heath, gardens, forest edge, and thicket. More fond of open habitats than other robin-chats. Away from South Africa, only found in the mountains. Song is a typical thrush-like series of inquisitive, cheerful notes.
