Reindeer. Male (bull) reindeer (Rangifer tarandus) migrating on summer tundra. A fully grown reindeer or caribou can weigh up to 320 kilograms and have a body length of up to 2 metres. Reindeer are herbivores that live in large herds and migrate twice a year. In summer they graze in the northern parts of their range and in winter they head south. The male reindeer's antlers are very large,branched and asymmetrical. The antlers are shed every year and their growth is controlled by sex hormones. Reindeer live in Arctic tundra and range from Scandinavia to Asia and northern North America. Photographed in the Arctic National Wildlife Refuge,Alaska,USA | |
