Kerguelen Tern
Sterna virgata
A slender tern with a short bill. Breeding adults are dark-capped with an ashy-gray body, a strongly contrasting white cheek stripe and rump, and a reddish bill and legs. In flight, underwings and uppertail are mostly grayish. In non-breeding plumage resembles other non-breeding terns, but note structure. Restricted to a handful of subantarctic islands, where it forages in inshore waters; common on Kerguelen and uncommon on Crozet and Marion. In breeding plumage, the larger Antarctic Tern is paler gray than Kerguelen, with a larger bill and whitish (not grayish) uppertail and underwings. Arctic Terns (in non-breeding plumage) only overlap with Kerguelen Terns (in breeding plumage) in austral summer.

Buff-faced Scrubwren
Aethomyias perspicillatus
A very small, drab bird of montane forest understory. Pale brown underparts, dark brown upperparts, Gray from the crown to upper back widening to a half-collar. Distinct buff face forming a disk around the eye. Found in active groups or mixed flocks, where it gleans leaves for insects. Similar to Large Scrubwren but Buff-faced is often found higher in the trees, is smaller with a buff eye-ring and gray crown. Song, an up-and-down, whistled “poo-pii-poo-pii-poo-pii!” and call, a nasal “rek!”.
Yellow-browed Antbird
Hypocnemis hypoxantha
Rather small antbird with a disjunct distribution. Males have a yellow face and underparts with a black crown, eye-line, and streaks on the breast. Females have a yellow streaked crown. Southeastern subspecies has ochraceous lower underparts. Song is a descending and decelerating series of fluted notes becoming harsher at the end. Found in the understory of humid forests, often in areas of transitional forest or poor soils. Rarely accompanies mixed-species flocks. The similar Spix's and Peruvian Warbling-Antbirds have white breasts, and the song of Peruvian is somewhat slower-paced.
Apo Myna
Goodfellowia miranda
A fairly large, long-tailed bird from montane forest in localized areas of Mindanao. Plumage mainly glossy black with a white patch on the back. Bill, legs, and large area of bare skin around the eye are yellow. Note the tall wispy crest. Forages in pairs or small groups for insects or fruits, sometimes with other species, including Coleto. Unmistakable. Voice includes slurred metallic warbles and a sharp, falling “tsik!” Also makes audible wing beats in flight.
