Gray-headed Kingfisher
Halcyon leucocephala
A medium-sized kingfisher with a distinctive chestnut belly, sapphire blue tail and flight feathers, ashy-gray head and breast, and vermillion bill. Pairs inhabit dry and moist woodland, especially riverine woodland; has been known to breed in riverbanks. It has complex movements and is a migrant in the southern part of its range. Calls a strident trilling “t-t-t-t-t-t-t”, although this can be weaker and less obtrusive than other kingfishers; also calls a repeated, squeaky “tsury, tsury”.
Identification
The sexes are similar. The adult of the nominate race H. l. leucocephala has a pale grey head, black mantle and back, bright blue rump, wings and tail, and chestnut underparts. Subspecies H. l. pallidiventris has a darker grey head and paler chestnut underparts but is otherwise similar. The beak is long, red and sharp. This bird grows to an average length of 21 cm (8.3 in). The song is a succession of notes, ascending, descending and then ascending again, becoming increasingly strident. The warning call is a series of sharp notes, "tchk, tchk, tchk, tchk".
Taxonomy
The first formal description of the grey-headed kingfisher was by the German zoologist Philipp Ludwig Statius Müller in 1776. He coined the binomial name Alcedo leucocephala. The current genus Halcyon was introduced by the English naturalist and artist William John Swainson in 1821. The name of the genus is from the classical Greek alkuōn, a mythical bird, generally associated with the kingfisher. The specific epithet leucocephala is from the classical Greek leukos meaning "white" and -kephalos for "-headed".<p>Five subspecies are recognised:

Behavior
A dry-country kingfisher of scrub and woodland, solitary or in pairs, often found near water, but unlike most kingfishers is not aquatic. Perches on a branch, unmoving for long periods while watching the ground for signs of insects or small lizards, bobbing head before diving on prey. In appearance very like the brown-hooded kingfisher but with a red rather than red and black bill and similar to the woodland kingfisher, but the woodland kingfisher lacks the chestnut belly and has greater coverage of cyan feathers on the back. Nests in holes in steep riverbanks and is aggressively protective of its nest by repeated dive-bombing of foraging monitor lizards. It is parasitised by the greater honeyguide. This species migrates at night and is often killed by flying into obstacles such as buildings, towers and powerlines.

Bornean Blue Flycatcher
Cyornis superbus
One of a number of similar blue flycatchers on Borneo; endemic to the island, where it inhabits foothill and lowland forests. Unobtrusive and not very active, often perching at lower and middle levels in the forest. Male is brightly-colored, but confusingly difficult to separate from other blue flycatchers; note his orange throat and underparts (darkest on chest), dark face, and paler blue crown and back. Female has brown upperparts, an orange chest, pale belly, and rufous-brown tail; also note her pale orange throat and very weak or absent eye ring. Song is a brief but quite beautiful series of tinkling notes.
Black Scoter
Melanitta americana
Plump diving duck, typically seen in flocks in coastal areas. Males are completely black with bright orange knob on the bill. Females are brown overall with pale cheek and contrasting dark cap. Note potbellied shape and rounded head in flight. Typically coastal, but migrates over land especially in the Northeast U.S. Often gathers in tight flocks. Dives frequently, feeding on aquatic invertebrates. Breeds on ponds in Arctic tundra.
Bay-chested Warbling Finch
Castanozoster thoracicus
Small finch with a conspicuous chestnut breast and flanks. Gray above with a white throat and belly and a white arc below the eye. Found at the edge of montane forests, in open woodlands, and clearings; often accompanies mixed-species flocks. Listen for its calm “tsip-cheep” song.
