Piping Hornbill

Male is unmistakable within its range: mostly jet black with bright yellow head. Female is mostly dark olive with brightest yellow concentrated on the upper breast. Stout pointed bill typical of a blackbird. Patchily distributed in northern South America, where is generally uncommon in marshy habitats, especially bordering lakes or rivers. Found in pairs or small flocks.

A medium-sized bird of lowland and foothill forest interior. Black upperparts, head and narrow band across the chin, white underparts, prominent white eyebrow, and patch in the wing. Sits still in the understory, often perching on trucks or vertical branches. Very similar to Black-sided Robin and co-occurs in some areas, but Black-chinned lacks the black on the sides of the chest, has a broader white eyebrow and a black chin. Song, a simple series of breathless whistled notes, first descending then rising at the end.

Restricted to the Azores, Canary Islands, and Madeira. Slightly bigger than European Serin and yellow-green overall with a pale bill, and a dark forked tail. Has a streaky rump, but this can be hard to see. Males are greenish-yellow below while females are duller and grayer on the breast and neck. The song is very melodic and rich. Found in forests, plantations, gardens, and orchards, sometimes gathering in flocks. Introduced to the Midway Atoll, where coloration ranges from unstreaked bright yellow to almost white.
