What kinds of birds in the South Pacific Islands migrate to other islands?
Inter-island dispersal is different from seasonal migration from breeding to non-breeding grounds. Red-footed Boobys (Sula sula) have two basic adult morphs; light in Hawaii, dark in Pheonix Is. When the light morph appears it is easy to identify as an intruder outside of its usually breeding grounds. These birds are pelagic or sea dwelling only coming ashore to breed. http://links.jstor.org/sici?sici=0010-54… Migratory birds that visit annually: Pacific Golden Plover (Pluvialis fulva), bristle-thighed curlew (Numenius tahitiensis), ruddy turnstone (Arenaria interpres) , sanderling ( Calidris alba), Tringa incana or wandering tattler.
