White-eyed Gull

Ichthyaetus leucophthalmus

A unique medium-sized, lightly-built gull, confined to the Red Sea. Upperparts dark brown or gray. The bill is long, slender, and slightly downcurved. Adults have black hood with a prominent white eyering. Young birds are browner with a paler head. Compared to the similar-looking Sooty Gull it is smaller and more delicate with a thinner all-dark bill, and lacks the two-toned bill pattern. Breeds on remote islands and coral reefs; mainly coastal.

Cryptic Flycatcher

Cryptic Flycatcher

Ficedula crypta

A small bird of foothill and low-elevation montane forest on Mindanao. Dark brown above with a rufous tail, a white belly, a pale gray chest, and a buffy face and throat. Forages low down or on the ground and may sit motionless for periods of time. Similar to female Little Slaty Flycatcher, but has a rufous tail, a brown throat, and black rather than orange legs. Gives a short descending trill.

Pink-footed Puffback

Pink-footed Puffback

Dryoscopus angolensis

Small bushshrike in which males and females are very different. Males are mostly black and gray, with white on the throat. Females are brown on the back, gray on the head, and buff below. Found in mountain and hill forest. Sometimes joins mixed-species flocks. The most common vocalization is a rising “cheeeu,” but also gives scolding and ratcheting calls. Somewhat similar to Sabine’s Puffback, but males separated by the gray rump and underparts, and females separated by their smaller size and less rufous coloration.

Black-tailed Trainbearer

Black-tailed Trainbearer

Lesbia victoriae

Small hummingbird with an exceptionally long tail. Green overall with a fairly short, slightly decurved bill. The male’s long tail is striking. Sexes similar but females are more spotted below and have a shorter tail. Could be confused with Long-tailed Sylph, but the trainbearer occurs in dry, scrubby, open habitats, not in forests. Compare with very similar Green-tailed Trainbearer; Black-tailed has a longer, more decurved bill, a longer tail that usually looks slightly curved, and is somewhat duller green. Occurs from Colombia to Peru, from around 2,500 to 3,800 m. Occasionally visits feeders, but more often seen feeding at flowering shrubs.
