Philippine Green-Pigeon
Treron axillaris
A medium-sized pigeon of lowland and foothill forest canopy, with green underparts, head, and rump, a gray crown, yellow wingbars and edges to the flight feathers, a whitish belly, and white under the base of the tail. Note the whitish bill with a reddish base and the blue eyes. Male has a maroon shoulder and back, where the female is green. Similar to Thick-billed Green-Pigeon, but Philippine has a thinner bill and lacks the green skin around the eye. Female resembles female Pink-necked Green-Pigeon, but that species has yellow marks only on the edge of the wing. Voice is typical of green-pigeons, including a rising-and-falling out-of-tune whistled song.

行为
The Philippine green pigeon usually occurs singly or in small groups. Its flight is fast and direct, with the regular beats and an occasional sharp flick of the wings that are characteristic of pigeons in general. It eats the seeds and fruits of a wide variety of plants. It builds a stick nest in a tree and lays two white eggs.

Blue Jay
Cyanocitta cristata
Familiar but stunning jay found year-round throughout most of eastern North America. Bright blue above and pale gray below with a fluffy crest. Also look for black necklace and black and white markings on the wings and tail. Pairs or small groups travel through mature deciduous or coniferous woodlands, often revealing their presence with loud, harsh “jay” calls. Frequently visits bird feeders, where it is often aggressive towards other birds.
Red-headed Woodpecker
Melanerpes erythrocephalus
Incredibly striking bird: adults have brilliant crimson head, black back, large white wing patches, and white belly. These large patches of solid color are unlike other woodpeckers with more intricate patterns. Immatures have brownish heads. Found in open forests with clear understories, including pine plantations and standing timber in beaver swamps. Often social, found in family groups. Regularly seen caching nuts in the fall, perched on snags, and sallying out to catch insects. Occasionally visits feeders. Nests in cavities.
Saunders's Gull
Saundersilarus saundersi
Elegant, dark-hooded gull, restricted to coastal East Asia. Small but stout-bodied and long-winged, with a dark bill in all plumages. Adult has a black head in breeding plumage; in all adult plumages, note distinctive white wingtips, unlike Black-headed. Black-headed Gull is generally similar, but larger, with a longer reddish bill and sturdier structure. Juvenile and first winter have black bill, unlike young Black-headed, which has pale reddish or yellowish bill base. Call distinctive, a high-pitched, ternlike “kee-eek.”
