White-fronted Scops-Owl
Otus sagittatus
Large for a scops-owl. This predominantly light brown species is most readily identified by its bright silvery-gray brow. Like other scops-owls, can be difficult to see; listen for its call, a series of low, rapid, trembling hoots that cuts off quickly. Predominantly found in lowland forest, though also ventures into lower foothills.
识别特征
The white-fronted scops owl (Otus sagittatus) is a small Asian owl in the family Strigidae. It has a declining population about which little is known, and is dependent on lowland and foothill forests which are rapidly being destroyed. This species of owl is considered vulnerable and has a population of about 2,500–10,000. It is found in the west of Thailand and also in peninsular Malaysia. Its range covers 149,000 km2 (58,000 sq mi) of forest at altitudes of 0–700 m (0–2,300 ft) above sea-level. The white-fronted scops owl was described by the American ornithologist John Cassin in 1849 and given the binomial name Ephialtes sagittatus. The species is monotypic. This kind of owl has two modes of defense. The first is that it can puff up its feathers to triple its body size. The second is that it can stretch its body upwards and turn its head at an angle in the direction of the predator that it is hiding from, reducing visibility.

Pallid Dove
Leptotila pallida
A rather plain medium-sized dove, mostly restricted to western Ecuador but also occurs in western Colombia and extreme northwestern Peru. Within range, the main confusion species is White-tipped Dove. Pallid Dove has notably darker and warmer brown upperparts that contrast more with the whitish underparts. Like other members of the genus, Pallid is typically found on the ground (or flushing up into the understory). It is most often seen walking on roads or trails, or flying across quickly. There are a few places where it visits feeders. Within its limited range, it is fairly common, but be careful to separate from the equally (or more) common White-tipped Dove. Listen for its low-pitched, single “hoo” call.

Tibetan Sand-Plover
Anarhynchus atrifrons
Medium-sized plover with a pale throat, brown back, and white belly. Breeding adults have a black mask and a bright orange chest and neck; males average brighter than females. Non-breeding and immature birds are brownish above and white below, with a variable white forehead and eyebrow. Compare with slightly larger Greater Sand-Plover; Tibetan is proportionally smaller-headed and darker-legged, and its shorter bill has a slight bulge at the tip. Smaller Kentish Plover can be similar in non-breeding plumage; Tibetan is taller and longer-legged, without Kentish’s strong white neck band. Very difficult to distinguish from Siberian Sand-Plover, especially nonbreeding and immature birds, though identification can often be presumed by range. In breeding plumage, note the more extensive black mask of Tibetan, typically lacking the white spot on the forehead of Siberian. In nonbreeding plumage, look for a generally broken breast band and clean white flanks in Tibetan. In areas of overlap many birds best left unidentified. Breeds on margins of high-elevation lakes and rivers in China and Mongolia; winters on coastal mudflats, beaches, and inland lakes from Africa to Indonesia.

Tiny Hawk
Microspizias superciliosus
Well-named, this is truly a small hawk, although size can be difficult to judge. Look for fine barring on the underparts, darker cap, and relatively short tail. Adults are gray, juveniles warmer rufous. Lacks a conspicuous collar wrapping around the neck, as in Semicollared Hawk. Not frequently seen; often stays inside forests, where it hunts small birds. Sometimes perches at the forest edge. Almost always seen singly.
