Blyth's Frogmouth
Batrachostomus affinis
Cryptic, uncommon nightbird of lowland and lower foothill forests (to 800 meters). Males show extensive barring on wings, whitish lower belly, and irregular white blotches on the breast. Females are warmer brown, almost rufous, with less wing barring and a wide “necklace” of white blotches on the breast. The only frogmouth in much of its western range. Vocalizations vary; male gives a series of rippling clear whistles and both sexes give harsh nasal croaks.
识别特征
Blyth's frogmouth is a small species that grows to twenty-three centimeters in length. The main color in their feathers is a shade of brown. These birds have a narrow white collar around their neck and abdomen, and scattered spots on their wings and tail. The males have a whitish lower belly with random white blotches on its breasts. The wings of the male also typically show extensive barring. The females are a warm brown, with the white blotches on the breast in the pattern of a necklace. The females also have a less wing barring than the males. The females have a more pigmented brown color than the males, and the younger birds are plainer with fewer spots. However, when just hatched, their feathers are a dark, off-shade of white.

分布与栖息地
Blyth's frogmouth is found in the tropical and subtropical moist broadleaf forests of Peninsular Malaysia, the Philippines, Sarawak, Sabah, Brunei, Borneo, Sumatra, and more. Frogmouths thrive in dense environments such as lowlands and hilly tropical rainforests.
行为
This bird is typically only seen at nighttime in the lowlands and the lower forests, to about eight hundred meters in elevation. Both males and females' vocalizations give harsh nasal croaks. In addition to these croaks, the males also vocalize rippling clear whistles. These birds spend most of their time roosting motionless on tree branches. Due to their brownish color, they camouflage well into the trees. Their camouflaging ability helps them to hide and protect themselves from their predators. This species makes a "caw" sound, like crows. Blyth's frogmouth is a nocturnal species, just like its family members. The species usually create small, padded nests on branches or tree forks. Their small stature and easily camouflaged color make these birds very difficult to identify. This species typically breeds from January to April. These birds are very vocal during breeding. They go from soft whistling sounds to loud jarring rattles.

Crowned Sandgrouse
Pterocles coronatus
Medium-sized sandgrouse, smaller than Spotted Sandgrouse. Rather compact build, lacking any long projecting tail feathers. Males have a distinctive black forehead and chin. Females are heavily patterned all over. Both sexes have an orange throat and a grayish crown and nape. In flight, shows a strongly contrasting two-toned underwing pattern. Flight call is a rather dry, nasal mumble, “hu-het hu-het.” Breeds on stony plains and hills in the harsh desert. Congregates at drinking spots in the morning.
Chatham Islands Parakeet
Cyanoramphus forbesi
Medium-sized bright green parakeet mainly restricted to Mangere and Little Mangere Islands on the Chatham Islands of New Zealand. Note distinctive yellow crown above a red forehead. Due to hybridization with Red-crowned Parakeet, some birds have red extending to and beyond the eye and a crown that varies from yellow-orange to orange-red. Males are larger than females. Will feed out in the open on flowering flax as well as in forest habitats. Commonly seen on the ground, scratching the surface like a chicken. Chatters quietly while feeding and often calls in flight. Forms small flocks in autumn and winter. Red-crowned Parakeet is present in the same habitat but lacks yellow on crown and has an obvious red band extending to, and beyond, the eye.
Black-billed Streamertail
Trochilus scitulus
Fabulous hummingbird restricted to far eastern Jamaica. It is now considered a separate species from Red-billed Streamertail, which is found throughout the rest of the island. Male sports an iridescent green body and black bill to go along with his characteristic tail streamers, though be aware that they might be missing in young males and molting birds. Female lacks a long tail and is much like female Red-billed Steamertail, but her bill is entirely black. Female is also similar to Vervain Hummingbird, but is larger and longer billed. Inhabits forest in both lowlands and mountains, and sometimes comes to feeders.
