Streaky-breasted Spiderhunter
Arachnothera affinis
Generic-looking spiderhunter, olive-green above with a streaky gray breast. The only spiderhunter on Java with well-defined streaking on dull gray underparts; the only other streaked spiderhunter is Long-billed, which has a much more impressive bill, as well as poorly-defined streaks and a yellow-washed belly. Immatures with unstreaked underparts may be confusing if seen, but general shape and patterning, as well as the presence of an adult, should be helpful. A species of foothill forests, where it forages in forest and forest edge habitats. Gives harsh, noisy chattering calls.

Other Birds
East Andean Antbird
Drymophila caudata
Slender, long-tailed antbird restricted to Colombia’s eastern Andes. Note the profuse streaking on foreparts and the orange belly and rump. Male’s streaks are darker and more contrasting than female’s. Similar to Klages's Antbird (little or no overlap), but central underparts are streaked instead of plain. Also very similar to Streak-headed Antbird and Santa Marta Antbird, but no range overlap. Inhabits bamboo thickets in cloud forest. Song consists of a few clucking notes followed by several rasps.
Streak-backed Antshrike
Thamnophilus insignis
Medium-sized, dark gray bird of tepui highland forest and scrub. Male has blackish back and crown with extensive white spots and streaks on wings and tail; note also grizzled white patch on nape. Female is similar but shows rufous in crown. Found in humid forest understory on tepui slopes, generally above 1000 m. Usually in pairs that forage deliberately at lower and middle levels, hopping between perches and peering about slowly in search of insect prey, like other antshrikes. May join mixed-species flocks. Song is an accelerating series of barking notes ending with an emphasis on the higher-pitched final note, similar to song of Barred Antshrike. Extensive white markings should distinguish this species from other antshrikes, none of which occur at higher elevations in the tepui region.
Spot-breasted Ibis
Bostrychia rara
Small, dark, forest-dwelling ibis. Note the blue bare skin on the face and the heavily spotted breast and neck. Found in the understory of moist rainforest. Very shy and generally scarce bird. The vocalization is a honking, two-parted goose-like call. Similar to Olive Ibis, but smaller and slimmer, with heavy spotting, blue facial skin, and a different call. Somewhat like Hadada Ibis, but much smaller, and found in forest rather than more open habitats.
