Ostrich (Struthio camelus camelus) aka North African Ostrich, Red-necked Ostrich. The scientific name is Greek for 'camel sparrow', an allusion to their long necks. Their eggs, weighing 1.3 kg, are the largest of all bird eggs, though they are the smallest in relation to the size of the ostrich. They live in nomadic groups of 5 to 50 birds and often travel with other grazing animals, such as zebras and antelopes. In the US, UK and Australia they are classified as dangerous animals. The males can be very aggressive and territorial. They kick with their very powerful legs, with enough power to eviscerate large animals, including people. The most widespread subspecies in Africa, they have been both hunted and farmed for their plumage, their skin (which makes excellent leather), and their meat. Range: all of Northern Africa from Ethiopia and the Sudan in the east across to Senegal and Mauritania in the west and Egypt in the north and southern Morocco. Jacksonville Zoo, Duval County, Florida.
