Buff-breasted Sandpiper
Calidris subruficollis
Elegant buffy sandpiper; peaceful-looking with large eye and plain face. Relatively short bill and medium-length yellow legs. Adults and juveniles similar, but juveniles show crisp scaly back pattern. Similar to Baird's Sandpiper but longer yellow legs and more evenly buffy coloration extending onto the belly. Smaller than Upland Sandpiper and lacks extensive dark markings on face, neck, and sides. Breeds on Arctic tundra. During migration, found in dry habitats such as plowed fields, sod farms, and higher areas of beaches. Winters in South America.

分布与栖息地
C. subruficollis breeds in the open arctic tundra of North America and is a very long-distance migrant, spending the non-breeding season mainly in South America, especially Argentina.<p>It migrates mainly through central North America and is uncommon on the coasts. It occurs as a regular wanderer in Western Europe and is not classed as rare in Great Britain or Ireland, where small flocks have occurred. Only the pectoral sandpiper is a more common American shorebird visitor to Europe.<p>This species nests as far north as Canada including Alaska on the ground, laying four eggs. The male has a display which includes raising the wings to display the white undersides, which is also given on migration, sometimes when no other buff-breasted sandpipers are present. Outside the breeding season, this bird is normally found in short-grass habitats such as airfields or golf courses, rather than near water.<p>These birds pick up food by sight, mainly eating insects and other invertebrates. The buff-breasted sandpipers are known to prey on Bombus polaris, a species of bumblebee found within the Arctic Circle. They will either eat the bees or feed them to their young. They are often very tame.<p>Buff-breasted sandpipers are suspected to have hybridized with the white-rumped or Baird's sandpiper.<p>This species has been sighted in South Asia on at least three occasions. It is believed that instead of going to Argentina, this bird might have been wind-blown from the Great Plains Flyway of North America and landed up in South Asia. In November 2011, this species was sighted near Kannur, Kerala in South India. The buff-breasted sandpiper has also been recorded in Australia on at least eight occasions. It was recorded again from Madayipara, Kannur in 2023.<p>In 1978, Phillips recorded the species from Sri Lanka, and after that, very few sightings were recorded. In 2001 a single bird was also recorded in Marievale, South Africa.

Black-and-yellow Broadbill
Eurylaimus ochromalus
Utterly unmistakable in its costume of black, white, yellow, and pink. Wide, deep-based bill, typical of the broadbills, is bright blue. Forages at middle to high levels in lowland and hill forests, frequently moving with mixed-species flocks and sallying out from a perch. Song is disproportionately loud, a series of high-pitched coos that increases in pitch and speed, turning into a maddened series of loud whistles. Frequently gives a jay-like “jeer!” call.
Chestnut-winged Chachalaca
Ortalis garrula
Long-tailed, chickenlike bird restricted to the lowlands of northern Colombia. The chestnut wings may be hidden from view when the bird is perched. It can be separated from the similar Rufous-vented Chachalaca by its white belly and pale (not rusty) tail tips. Distinguished from Colombian Chachalaca by lack of scaling on head and breast. Inhabits lightly wooded areas and mangroves. Easier to see early in the morning and late in the afternoon when it often perches up in the open and gives loud, raucous calls.
Masked Yellowthroat
Geothlypis aequinoctialis
Skulking warbler of grassy areas such as overgrown fields and marshes. Male has a striking black bandit mask, and his gray crown helps to separate him from other yellowthroats in range. Female is plain and confusing; she is yellower on the belly than female Common Yellowthroat, and tends to have darker upperparts than Olive-crowned Yellowthroat. Female also similar to female Yellow Warbler, but has a thicker bill and darker back. Song is a rather variable series of sweet whistles; also give a short, descending churr. Pairs usually stay hidden in dense vegetation. Males occasionally come up to sing or call from a more exposed perch. Note its range; after a taxonomical update, this species ranges only in northern South America.
