Wallace's Owlet-nightjar
Aegotheles wallacii
A medium-sized owlet-nightjar of foothill forests. Dark brown wings and tail with barring and some additional white flecks on the wings. Dark head, whitish belly and buffy base to the chest covered with irregular, dark arrowhead marks. Potentially co-occurs with Mountain, Vogelkop and Barred Owlet-Nightjars, but Wallace’s lacks the distinct barring of Barred and Vogelkop, and the pale collar of all 3 species. Voice a simple, whistled “pweet pyuut” with the first note falling and second lower. Sometimes just one of these notes given.

Azure-crowned Hummingbird
Saucerottia cyanocephala
Medium-sized hummingbird of oak and pine-oak woodlands and adjacent shrubby clearings; also local in lowland pine savannas. Sexes look alike and often look rather dull overall, despite the name. Note the whitish throat and breast offset by a dusky vest, and the dusky brownish rump and tail. Crown and sides of head are blue (rarely catching the light), with a white spot behind the eye and some red at base of bill.
Yellow-capped Pygmy-Parrot
Micropsitta keiensis
A tiny parrot of lowland and foothill forest canopy in the south and west of New Guinea. Mostly green with yellow under the tail and a yellowish crown. NW birds have a red streak on the belly. Crawls actively on trunks, even upside down, like a nuthatch. May overlap with Red-breasted and Buff-faced but Yellow-capped lacks the blue crown and buff face. Call, a shrill, descending screech “kiiiiiii!”.
Black-headed Duck
Heteronetta atricapilla
An uncommon and easily overlooked small duck of lakes and wetlands, usually with surrounding reeds. Mainly seen singly or in pairs, sometimes in small groups, and at times sleeping with Lake Ducks. Note the long and low profile in the water and the long gray bill with a pink band at the base on males. Males have a black head, but females are notably drab brownish overall and are best identified by size and shape, and association with a male. Lays its eggs in nests of other birds, such as coots, ducks, and even herons. Ducklings fend for themselves.
