Sharp-shinned Hawk
Accipiter striatus
Small hawk with relatively short rounded wings. Adults are gray above with pale orange barring below; immatures are browner and streaky. Very similar to Cooper's Hawk, especially in plumage, but smaller overall with smaller head, more squared-off tail, and more petite feet. Also note quicker, snappier wingbeats. Breeds in extensive forests. Feeds mainly on birds captured in flight. Often stalks feeders in search of prey.
识别特征
The sharp-shinned hawk (Accipiter striatus) or northern sharp-shinned hawk, colloquially often nicknamed sharpie, is a small hawk, with males being the smallest hawks in the United States and Canada, but with the species averaging larger than some Neotropical species, such as the tiny hawk. The taxonomy is far from resolved, with some authorities considering the southern taxa to represent three separate species, white-breasted hawk (A. chionogaster), plain-breasted hawk (A. ventralis), and rufous-thighed hawk (A. erythronemius). The American Ornithological Society and some other checklists keep all four species conspecific. A recent genetic study additionally recommended splitting the three Caribbean island populations as three additional separate species, though this has not yet been adopted by any of the ornithological authorities.

White-spotted Woodpecker
Veniliornis spilogaster
Small, noisy woodpecker, common in a variety of forested habitats including urban parks. The body is largely olive-green and heavily barred, including the tail. Note two white stripes above and below the eye and a pale throat. Males have a red crown that is lacking in females.
Green-backed Kingfisher
Actenoides monachus
An unmistakable, spectacular large forest kingfisher with a big orange bill, a moss-green back, burnt-orange underparts, and a white throat. Head is bright azure-blue in north and central Sulawesi, but very dark blackish-blue in the south. Females show rufous facial markings that are absent in males. Juveniles are duller, with horn-colored bills. Found singly and in pairs in forest understory of lowlands and lower hills. Vocal around dawn, when it repeats drawn-out mournful whistles, “woooo-eEEE,” that get gradually louder. Also gives a distressed dry chatter.
Green Kingfisher
Chloroceryle americana
Small kingfisher with disproportionately long bill. Dark glossy green above with white throat, collar, and spots on wings. Tail often held cocked up. White outer tail feathers spotted with green conspicuous in flight. Male has rufous breast; female breast white with spotted green double-collar. Found along rivers or ponds. Less conspicuous than some other kingfishers, often perching on overhanging branches close to water's surface. Low flight with quick wingbeats.
