Taiwan Yellow Tit

Medium-sized gull with a long, slender bill. Breeding adult has a clean white head and dark red bill, and frequently shows a strong rosy-pink flush to the underparts. Non-breeding adult similar, but may show slight smudge on the head. Immature has orange bill with small brown patches on the wings, most readily seen in flight. Compare with Black-headed Gull; note Slender-billed's longer bill, sloping forehead, and "snouty" profile. Breeds in colonies in inland and coastal wetlands, but restricted to coastal wetlands when not breeding. Away from main range, found singly or in pairs, at times in association with much commoner Black-headed Gull.

Handsome black-and-white crow. Found in almost all habitats except driest desert and thick rainforest. Feeds by walking along the ground. Strong flier that will fly high and occasionally soar. Common call is a typical crow “crawk”. Overall shape and size similar to some raptors, but none of them show Pied Crow’s contrast between black tail, white underparts, and black head. 

Glossy large-billed drongo with glossy blue-sheened wings and tail. Also note bright red eyes, iridescent speckling around the throat and neck, and flared broad-tipped tail. Endemic to Sumatra, where it is the only regularly-occurring “Hair-crested type” drongo, a group which has undergone extensive taxonomic changes recently; some older field guides may refer to this taxa as either Hair-crested or Spangled Drongo. Inhabits foothill forests, where it often associates with mixed flocks in the upper and middle levels of forest. Can be a source of confusion with other drongos, such as Black, Lesser Racket-tailed, Bronzed, and Crow-billed, but note habitat, distinctive tail shape, and flat-headed profile. Gives a variety of vocalizations, including bright fluty whistles and harsh chattering.
