Photograph by David Chancellor - @chancellordavid - a herd of red deer in velvet, Cairngorm National Park, Scotland - Britain's largest wild mammal, the red deer migrated into Britain from Europe 11000 years ago. Mesolithic people hunted Red Deer for food, using their hides for clothing and their antlers for tools. Neolithic man developed agriculture and as the forests were cleared, the Red Deer population became confined to the Scottish Highlands, south-west England, and a few other scattered populations. The Normans protected red deer in parks and forests for royal hunting, but this protection was lost during the Mediaeval period causing another decline in numbers in England. Victorian re-introductions of "improved” stock; often inter-bred with larger related species such as Wapiti, and an increase in forest and woodland cover since the early 20th century, mean that red deer are now widely distributed in Britain and are expanding in range and number. It's a herbivore, grazing on a wide variety of plants such as heather, grasses, shrubs and trees. The Red Deer’s natural predators – bears and wolves – are extinct from Britain, but vulnerable calves are predated by eagles and foxes. The lifespan of a Red Deer can be as long as 18 years, but among young deer there is a high mortality rate, especially here in the Scottish highlands where many calves are lost shortly after birth or during their first winter. A Red Deer’s antlers start growing in the spring from the age of 10 months, and they are shed or cast when testosterone levels fall in mid-March and April. Each successive year sees the Red Deer stag’s antlers become longer and wider, with more points or ‘tines’. Antlers are made of bone, and can grow at the rate of an inch per day. While they are growing, the antlers are covered with ‘velvet’ which is a soft, blood-filled, bone-forming tissue and is very sensitive. In July, the Red Deer’s antlers have stopped growing and the velvet is shed by rubbing against trees and posts - to see more work from work and projects follow me here @chancellordavid @thephotosociety @everydayextinction #conserving #cairngormsnationalpark #wildlife #scotland #wildfire #reddeer
