Nihoa Finch

Large screech-owl found in temperate forests, typically from around 2,300–3,400 m. Quite dark brown overall with small pale spots and bars covering head, back, and wings. Belly is paler tawny with dark streaks. White throat patch is usually obvious. Sexes similar. Strictly nocturnal and thus more often heard than seen; listen for a fairly short and slow series of toots that descends in pitch, often given as a duet.

Small and modestly bright warbler of lowland to submontane forests, usually seen moving around quickly in the undergrowth. Not especially eye-catching, but combination of olive-green upper parts, bright yellow belly, and white eyebrow and throat are unique within its range. Usually seen in small flocks, often with other species. Song is a short, pretty phrase of tinkling high whistles, the highest note often at the end.

A large, chunky, scraggly-looking babbler found in limestone hills covered with forest. Gray and brown overall with heavy streaking on the head, back, and throat. An odd white morph shows a variable amount and distribution of bright white on the head and breast. Forages close to the ground, often in and around rocky cracks and crevices. Song is a loud, ringing, rather hoarse-sounding sequence of whistled notes including some repeated phrases, sometimes given as a duet by a pair. Also gives harsh “grrr” calls. Similar to Streaked Wren-Babbler, but larger and longer-tailed, lacking white spots on the shoulder.
