Such's Antthrush

Very similar to Band-rumped and Monteiro's Storm-Petrels, and closely related to those taxa. Breeds only on Cape Verde islands. There are no published field identification features to tell them apart. However it appears that its upperwing pattern is more contrasting and the rump patch is broader. Breeds in burrows and crevices on islands. Burrow calls are different from Band-rumped and Monteiro's by being extremely long, without pauses.

Uncommon throughout most of its range, this elusive rock thrush breeds in rocky hill forest in northeastern China and Russia and migrates down the East Asian coast to winter in southern China and mainland Southeast Asia. Beautiful and distinctive male has a blue crown, orange underparts, and black wings marked with a bright white patch; small white patch on throat is not obvious and difficult to see. Female is brown with scaly markings on her back and breast; she lacks a pale crescent behind the eye. Usually stays low in shrubbery, but male will sing from an exposed perch.

A large shorebird with a long, curved bill. Similar to Whimbrel but warmer brown and with a cinnamon-colored rump. The bristly feathers on the upper legs are visible at close range. Breeds in upland tundra; during the nonbreeding season occurs in wetlands, sand dunes, rocky shores, pastures, and golf courses. Almost exclusively occurs in remote, hard to reach areas throughout the year, though does winter in reasonable numbers on the Hawaiian Islands (especially Oahu). Call is a loud “kee-oo-ee”, notably different than the common call of Whimbrel.
