Bornean Green-Magpie

A medium-sized flycatcher with strikingly different male and female plumages. Male is beautifully colored, with deep blue upperparts, mostly orange underparts, and a white belly. Female is much duller, with a grayish head, gray-brown wings, a rufous tail, and rufous underparts. Scarce and local in the understory of hill forest. Song is jumble of melodious warbling and whistling notes. The calls are loud “chek” or “sit” notes, and are often mixed into the song. Similar to Bornean Blue Flycatcher, but darker, especially on the belly (in both sexes) and back (in the male). Also similar to Sunda Blue Flycatcher, but darker overall and shorter-billed. Dayak Blue Flycatcher is further distinguished by the less extensive black chin patch of the male and the rufous rather than blue tail of the female.

A light gray medium-sized tern. Black cap extends to bill in breeding plumage. Bill and legs red. In non-breeding birds, cap reduced to just the area behind the eye, bill has dull pinkish color, and underparts are white. Breeds in the circumpolar subantarctic region. Generally known to stay close to their breeding sites. Migrating Arctic Tern could occur in the same area, but not in breeding plumage, and would show more prominent black markings on outer primaries. White-fronted Tern can be distinguished by its larger body, lighter coloring, and longer, thinner, all-black bill.

A fairly small bird of lowland and foothill forest floor or dense undergrowth. Warm brown on the upperparts, crown, and sides, with fine buff streaks on the sides and blackish underparts heavily streaked white. Note the contrasting white throat, the black-and-white moustache stripes, and the white stripe from above the eye to the back of the head. Unmistakable in range. Voice includes a variety of medium-pitched whistles, including repeated piping, downslurred notes, plus complex jumbled songs and imitations of other bird species.
