Styan's Bulbul
Pycnonotus taivanus
Relatively plain songbird, olive above, whitish below, with black cap, white face, and black moustachial mark. Somewhat similar to more widespread Light-vented Bulbul, with which it hybridizes, but adult Styan’s has heavier bill, solidly black cap, white plumage surrounding the eye, and small red dot in black moustachial stripe (difficult to see). Juvenile duller above (greenish in wings), white below, lacking strong head pattern. Inhabits open forest, forest edge, parks, and gardens. Often perches on telephone poles or fences, from which it gives a melodic song similar to that of Light-vented but higher in pitch and more musical.
识别特征
Styan's bulbul has a very similar appearance to the light-vented bulbul, but they differ in the patterns on the head. Styan's bulbul has a completely black crown with white feathers around its eye, except for a black moustachial stripe below the beak. Hybrids are intermediate between the two species, with the moustachial stripe and white feathers around the eye, but the white feathers extend behind the crown.
分类信息
Alternate names for Styan's bulbul include the Formosan black-headed bulbul and Taiwan black-headed bulbul. The latter name is also used to refer to a subspecies of the light-vented bulbul.

Yellow-tufted Woodpecker
Melanerpes cruentatus
Loud, colorful woodpecker of lowland forest. Bold black and yellow coloration is distinctive. Frequently perches on tall snags in mature forest and secondary growth. Highly social and is often seen in groups, especially around nesting colonies.
Black-bellied Thorntail
Discosura langsdorffi
Tiny, coquette-like hummingbird. Males are iridescent emerald green with a black belly, bold white rump band, short crest, and long, straight tail feathers. Females are similar, but are duller below with a shorter tail. Compared to the similar Festive Coquette, females have darker plumage. Usually found in mature rainforest, where it forages at flowering trees at all levels of the forest.
Marsh Sandpiper
Tringa stagnatilis
Slender pale sandpiper with a fine, needle-like bill. Note the overall slim and elegant shape, with very long and slender greenish legs: suggests a much smaller Greenshank that’s been to ballet school. In flight appears dark above with broad white stripe up middle of back; long legs project well past tail tip. Usually found singly or mixed in with other waders in varied fresh to brackish wetland habitats, usually with open water. Feeds by wading in water, picking with its bill. Repetitive mellow calls somewhat similar to Greenshank, but rather monotone and with a sharper quality.
