Seram Thrush

A medium-sized dove of lowland secondary forest on Tawi-Tawi Island, where it is the only brown-dove. Dark brown above with a gray head, purplish iridescence on the back of the neck, rufous-brown underparts from the throat to the belly, white under the base of the tail, and a pale gray tail tip. Does not resemble any other similarly sized doves in its range. Sings an accelerating series on the same pitch, ending in a trill, “dup-dup-dup-du-du-d-d-drrrrr,” reminiscent of a ping-pong ball falling on a table.

Supreme understory skulker in montane forest, resembling a hybrid between a thrush and babbler. A dull but distinctive-looking bird if seen well, with brown-olive upperparts and rusty underparts, a bold dull blue-gray eye-ring and black-speckled tawny throat. The bill is dark on top and pale underneath. Immature is paler, lacking the spotted throat. Singles or pairs are highly localized residents flicking through leaf litter or following ants in undergrowth of Eastern Arc montane forest, between 900–2700m; shy and hops or runs quickly across the forest-floor, seldom permitting absorbing looks. Thrush-like song is a varied but distinctive shrill series of whistles and slurs. Calls include a single upslurred sweet “seeuuuiit”, and a scratchy “werrrt” in alarm.

Elegant, dark-hooded gull, restricted to coastal East Asia. Small but stout-bodied and long-winged, with a dark bill in all plumages. Adult has a black head in breeding plumage; in all adult plumages, note distinctive white wingtips, unlike Black-headed. Black-headed Gull is generally similar, but larger, with a longer reddish bill and sturdier structure. Juvenile and first winter have black bill, unlike young Black-headed, which has pale reddish or yellowish bill base. Call distinctive, a high-pitched, ternlike “kee-eek.”
