Little Green-Pigeon
Treron olax
This aptly-named forest species is the smallest of the green-pigeons. Males are highly distinctive, with a blue-gray head and neck, orange chest, pinkish-maroon back, and green belly. Females are duller, but their combination of size, gray crown, and contrasting yellow-green chest serves to tell them apart from other green-pigeons. Pairs often forage and perch together, often on exposed bare branches. Like other pigeons, frequently gathers at fruiting trees. Song is a series of strangely buzzy rising whistles.

Spot-bellied Eagle-Owl
Ketupa nipalensis
Immense and imposing owl of dense wet lowland and hill forests. Silver-gray adult is majestic, with a large yellow bill, black eyes, and sweeping sidewards-facing “horns.” Juvenile is much paler, almost white, with shorter tufts. Gives deep echoing hoots. Primarily nocturnal, but will on occasion hunt by day; takes prey as large as small deer.

White-faced Storm-Petrel
Pelagodroma marina
Striking white-bodied storm-petrel with distinctive flight style: glides on stiff wings and bounces across the sea surface with both feet, much like a hopping kangaroo. Plumage also unique; look for mostly white face with dark mask. Also note extremely long legs projecting far beyond tail and rather long, slender bill. Fairly common and widespread in subtropical and tropical waters across the globe, with several disjunct and subtly variable populations. Can be seen singly or in groups when feeding; rarely mixes with other species of storm-petrel.

Narrow-billed Tody
Todus angustirostris
A small, gemlike species that prefers higher elevation moist woodlands, but also occurs in coffee plantations. The rather large head, long bill, and short tail create a profile shared only by the Broad-billed Tody within its range. Both species have bright green upperparts and a red throat and sides. Note especially the pale eyes of Narrow-billed Tody, as compared to the dark eyes of Broad-billed. Many Broad-billed also have a buff-yellow wash below, which the Narrow-billed lacks. On birds lacking buff below, the Broad-billed can be identified by its all red lower bill, which is black tipped in the Narrow-billed. Further clues to identification include altitude, with this species occurring above 700 meters elevation and the Broad-billed occurring mostly below 700 meters. The Broad-billed also tends to forage higher within woodlands on more open perches. Vocalizations include a buzzy “chik-zhwik” with second note slightly upslurred and a rapid buzzy chatter at about 14 notes per second; compare this with the quick “weep” or “whip” uttered by the Broad-billed.
