At Letterewe estate many red data birds can be found, including golden eagle, merlin and peregrine, dipper, golden plover and dotterel. In the upper heathlands there are small numbers of red grouse and ptarmigan.
The tranquility of the estate provides an ideal environment for a variety of mammals like, badger, red fox, otter and pine marten.

Stalking on Letterewe is still managed in the traditional manner including the use of ponies to carry out the deer. We sell our venison to the local butchers. In June 2002, after three years of research, a book "a Highland Deer Herd and its Habitat" was published in order to assist with the effective future management of Letterewe estate. Deer have an important role in the rural economy, providing an income from hunting and venison.
