Beast Of Exmoor

British Big Cat of southwestern England.

Significant sightings:

Attacks on livestock gained prominence in Devon in the spring of 1983, though scattered reports of a black animal in the area go back to 1982. Eric Lay, of Drewstone Farm near South Molton, thought he had lost at least forty lambs over the previous few months. Local police called in the Royal Marines, which held stakeouts in early May and June 1983 as part of Operation Beastie. They were able to observe the animal through nightvision equipment. Reports of both large cats and dogs were logged.

By late June, there were eighty-six kills, but these dropped off in July.
Two boys, Wayne Adams and Marcus White, saw the Beast on May 29, 1983, at Willingford Farm on Exmoor. It was jet black with some white markings and powerfully built. Though its head looked like a German shepherd dog’s, the animal moved like a cat. The same night, a sheep was killed at Ash Mill.

Trevor Beer saw a black cat measuring 4 feet 6 inches in the summer of 1984 at a cache of deer carcasses on Exmoor that he had discovered earlier in the year. It ran swiftly and had powerful

In January 1987, Trevor Beer discovered nine lynxlike pawprints 3 inches in diameter at Muddiford, Devon. In August, he took nine photos from a distance of about 100 yards of a black cat, 4 feet 6 inches in length, that stalked and killed a rabbit on Exmoor.

In 1990, Lars Thomas led an expedition (Operation Exmoor) to investigate sightings. At the site of a sheep kill, he found a tuft of hair that was identified as belonging to a puma.

Possible explanations:

(1) Trevor Beer proposed that feral Domestic dogs (Canis familiaris) were killing livestock, but large cats of some kind were also in the neighbourhood. He noted that about 20 per cent of the sightings involved a fawn-coloured
(2) Large, feral Domestic cats (Felis silvestris catus) were suggested at first by Nigel Brierly, perhaps representing a hybrid strain that has attained puma-sized proportions.
(3) A black Puma (Puma concolor) was Brierly’s later conclusion, though melanism is virtually unknown in this strictly American species.
(4) An unknown species of indigenous big cat, suggested by Di Francis.
(5) A Eurasian lynx (Lynx lynx) explanation was favoured by Frank Turk after lynx hairs were identified at a sheep kill in 1986.

Lynxes became extinct in Britain during prehistoric times. In May 2001, a specimen later nicknamed “Lara” was captured in Cricklewood, North London, following a reported big-cat sighting. It was believed to be an escaped or abandoned pet. There are reports of lynxes on the loose elsewhere on the island, which has led to speculation about a relict lynx population.
