The Spur-winged Goose (Plectropterus gambensis) is a very large, 39" (100cm) bird, commonly found on the freshwater wetlands of Kenya below 300 metres. The Spur-winged Goose has a pied appearance, with pink beak and legs, with a white face. The black of the neck and back appear glossy in strong light, contrasting with the white underparts. Only the male has a warty face, with a large red knob on its forehead. Its call is like a hiccup "ku-wup-up". Weighing up to 15lbs (7kg), these are formidable geese, featuring a pointed bone that projects from the bird's wing. A conical shape, these 'spurs' stick out a couple of centimetres and are used for both defence and attack. The spurs can also be poisonous, with some populations of Spur-winged Geese feeding on a poisonous blister-beetle, storing the poison in their tissues and making themselves toxic to predators. No wonder these Geese are unpopular to hunters. They taste awful..!
