The spur-winged goose (Plectropterus gambensis) is a large, Sub-Saharan African waterbird in the family Anatidae, which includes geese and shelducks. However, P. gambensis developed unique environmental adaptations, which resulted in the evolution of several anatomical features that are not shared with other anatids; thus, the species has been classified one step further into its own subfamily, the Plectropterinae.
This species often occurs in open grasslands with lakes, seasonal pools, rivers, swamps and river deltas. Large inland rivers and lakes are perhaps most commonly inhabited, with saline lakes and upland areas generally being avoided.
Some populations of the spur-winged goose are toxic. Populations that have a diet that includes significant quantities of blister beetles are poisonous. The poison, cantharidin, is held within the tissue of the bird resulting in poisoning of those that eat the cooked goose. A dose of 10 mg of cantharidin can kill a human.
