Oustalet's Sunbird

Scimitar-billed large shorebird of varied open habitats. Note large size, overall brown plumage, and long, decurved bill (appreciably shorter on juvenile). In flight shows white back patch, mostly white underwings. Common call an onomatopoeic "coor-lee." Compare to smaller Whimbrel, which has head stripes, a piping whistled call, and Far Eastern Curlew, which has a buffy rump and extensively marked underwings. Breeds mainly in grasslands, from coastal marshes to upland moors; winters mainly in coastal lowlands, especially mudflats and adjacent marshes.

This small slate-gray tailorbird is restricted to dense floodplain scrub in southeastern Cambodia. Males have a patchy black throat and both sexes have an orange crown that is slightly more extensive in males. Forages low in dense vegetation, often in pairs. As with many other tailorbirds, song is loud, vibrant, and variable; calls are squeaky and nasal.

Large, stocky bird. Green-and-chestnut plumage can look mostly black under some conditions and at a distance. Note size, yellow tail, and deep, rowing wingbeats. Reliably distinguished from other green-plumaged oropendolas by pale green-and-red bill. Found in rainforest canopy and edges as well as along rivers, in villages, and in savanna woodlands. Groups move noisily through the forest canopy in search of fruit and flowers. Large flocks are sometimes seen commuting between roosting and feeding areas. Distinctive song of male can be heard at a great distance.
