Greater Vasa Parrot
Coracopsis vasa
Large black parrot that is found in and around all types of forest. Often seen in flight, sometimes in small, loose flocks. Incredibly loud calls consist of rough squawks and low whistles. Can be very hard to separate from Lesser Vasa Parrot, but larger and bigger-billed, with a straight edge to the skin at the back of the bill. Vocalizations are lower-pitched and rougher than those of Lesser Vasa Parrot. Can easily be mistaken for a raptor in flight, but has all-black plumage unlike any raptor in range.

The greater vasa parrot's breeding season is uncertain, but is probably between October and December. It has a very unusual breeding biology and mating system; females are 25% larger than males, and are, physically, dominant. The species lives in loose, polygynandrous groups wherein each female has at least 3-8 sexual partners. The males have re-evolved a phallus, and copulations can last up to 90 minutes. Copulations come in two lengths—short (1–3 seconds) and long durations (averaging 36 minutes), with the latter involving a copulatory tie. A copulatory tie usually applies to mammals, such as canids and felids, where the two animals are unable to physically part during mating due to the swelling, and structure, of the penis within the female's body (being barbed or lined with small "hooks" in some species). During brooding and chick-rearing, females shed their head feathers and develop bright orange skin coloration, and also sing complex songs from perches close to the nest. These serve to attract males to approach and regurgitate food, which the female accepts while off the nest. The females also defend a territory around their nest from other females during this period.

Everett's Scops-Owl
Otus everetti
A fairly small owl of lowland and foothill forest. Dark brown on the back with barred wing feathers, grayish underparts, a darker chest with black markings, a pale gray facial disk bordered with a black line, and pale ear tufts forming a V. Occurs together with Giant and Mindanao Scops-Owls, but Everett’s is much smaller than Giant and slightly larger and paler than Mindanao, with longer ear tufts. Voice includes a descending series ending in a growl, “oowok! oowok! oowok! grrrr.”

Greater Sand-Plover
Anarhynchus leschenaultii
Medium-sized plover with a long hefty bill. Breeding adults have a dark mask and orangish chest, neck, and forehead; females duller than males. Non-breeding birds and immatures are sandy brown above and white below, with a white throat and “eyebrows.” Often confused with Lesser Sand-Plover, and best distinguished when both present; look for larger size, heavier and longer bill, paler legs, and larger-headed appearance. Additionally, unlike some Lesser Sand-Plovers, Greater never has a black boundary around the throat. Breeds in high-elevation areas, where it favors arid, open habitats, sometimes near water. Winters on coastal mudflats and estuaries.

Fulvous Wren
Cinnycerthia fulva
Reddish-brown wren with a faint pale eyebrow found in the understory of humid montane forest. Larger and longer-tailed than the tiny Mountain Wren, which also has a bolder eyebrow. Replaced at the northern end of its range by the very similar Peruvian Wren. Forages singly or in pairs low in bushes and near the ground. Listen for its loud song, a flowing series of whistles and trills.
