Crimson-rumped Toucanet
Aulacorhynchus haematopygus
Medium-sized, grass-green toucan of humid tropical forest from foothills to highlands. Usually in pairs or small groups, moving through the canopy or feeding at fruiting trees. To separate from Emerald Toucanet, look for all dark maroon bill and red rump patch. Listen for long series of repeated barking notes.
识别特征
The crimson-rumped toucanet is 40 to 45 cm (16 to 18 in) long. The nominate subspecies weighs 200 to 232 g (7.1 to 8.2 oz) and A. h. sexnotatus 141 to 200 g (5.0 to 7.1 oz). Their bill is brownish red and black with a vertical white line at the base; the nominate has a larger proportion of black than A. h. sexnotatus. Males and females have the same plumage but females have a shorter bill than males. Adults of both subspecies are mostly green with a gold gloss to the nape and upper back, a red rump, chestnut tips on the central two or three pairs of tail feathers, and bare orange-brown skin around the dark eye. The nominate has blue above and below the eye and on the sides of the breast. A. h. sexnotatus has less blue in those areas. Immatures are duller overall, with an orangey rump and a mostly reddish bill without a white basal line.

分布与栖息地
The nominate subspecies of crimson-rumped toucanet is found from western Venezuela's Serranía del Perijá south on both slopes of the Andes through northern and central Colombia to its southwest. Its range might extend into northern Ecuador on the eastern slope of the Andes. A. h. sexnotatus is found on the western slope of Colombia's Western Andes in Nariño Department and south to Loja Province in Ecuador. The species primarily inhabits evergreen forest from the lowlands to the montane zone and is also found in semi-open landscapes like forest edges, secondary forest, and isolated fruiting trees in pastures and gardens. In elevation it mostly ranges between 300 and 2,200 m (980 and 7,200 ft) but is found as high as 2,750 m (9,000 ft).

Northern Emerald-Toucanet
Aulacorhynchus prasinus
Medium-sized, grass-green toucan of humid tropical forest in foothills and highlands; also very locally in lowlands. Usually in pairs or small groups, moving through the canopy or feeding at fruiting trees. Nothing similar in its range. Note the rusty tail tips, best seen from below. Pattern of black and yellow on bill varies from region to region.
Sabine's Gull
Xema sabini
Small oceanic gull with stunning wing pattern. All ages show distinctive black outer wing, white inner wing, and dark back. Breeding adults have a dark gray head and black bill with yellow tip. Nonbreeding adults have similar distinctive bill but with a mostly white face. Young birds are browner above than adults, with a crisp scaly pattern on the back. Breeds on Arctic tundra. Often seen in flocks during migration and winter, generally far offshore. Rarely seen from shore, but occasionally shows up at large inland bodies of water.
Japanese Quail
Coturnix japonica
A compact, cryptically-colored, very shy bird of grassy areas, including both natural meadows and some agricultural fields, where it remains hidden from view on the ground unless flushed at close range. Both sexes brown overall with a pale face, long white eyebrows, and subtle stippling and striping on the back and breast. Breeding males have a reddish-brown face and throat. Vocal mostly during the breeding season; males give a dry, explosive three-noted song from cover. Flushed birds fly with noisy, whistling wings, unlike crakes or shorebirds. Introduced to Hawaii, found on all of the main islands. A common avicultural bird, so escapees may occur around the world.
