SHELDGOOSE

any of the larger members of the duck tribe Tadornini, family Anatidae (order Anseriformes). The smaller members of the tribe are called shelducks. Sheldgeese inhabit tropical and subtropical regions worldwide. They are small-billed and rather long-legged, with upright stance; some have bony spurswhich function as weaponsat the wing bend. Typically they show white wing patches and are finely black-barred below. They are not true geese, though they resemble them in some anatomic features. Among the sheldgeese are several South American species of Chlophagathe kelp goose (C. hybrida), the Magellan goose (C. picta), and the Andean goose (C. melanoptera)and the Orinoco goose (Neochen jubatus). African sheldgeese include the spur-winged goose (Plectropterus gambensis) and the Egyptian goose (Alopochen aegyptiacus).
