Bornean Crestless Fireback

Large and chunky stiff-tailed diving duck with a heavy triangular bill. Floats very low in the water. Both sexes are dark grayish, but male has an obvious lobe of skin dangling from its chin. Usually observed on the water, regularly diving while feeding. Bill is much shorter and heavier than Blue-billed Duck.

Very large and spectacular hummingbird of humid forest and brushy woodland in highlands of Chiapas and northern Central America; uncommon and local. Feeds mainly at low to middle levels, often inside shady understory. Male and female look similar, with thick, slightly arched black bill, pale rusty underparts, and large, broad tail with rusty base and buffy corners. No similar species in its localized range.

A typical thrush in shape and size, but with unusual brown coloration. Varies significantly across the three islands where it occurs, and these populations may be full species. The Grand Comoro birds have plain pale brown underparts, the Moheli birds have darker blotching below, and the distinctive Anjouan birds are scaled on the underparts. Found in humid forest, secondary habitats, and plantations, mostly at higher elevations, though down to sea level in some places. The song is a typical thrush mix of whistles and quavering notes, whose exact structure varies on the different islands. Also gives “pik” notes, short trills, and a high-pitched “seet.”
