Mustela erminea

Overview
Stoats are agile, fast-moving predators that hunt rabbits, voles and birds across the Sefton Coast. They sometimes turn white in winter (ermine) though this is more common in colder parts of Britain — Sefton birds may show partial whitening. They're seen less often than heard — the squeal of a rabbit being caught is not an unusual sound in the dunes. Sometimes they perform a 'dance' to hypnotise rabbits, bounding around until the confused prey stands still.

Where to See It
Dune grassland at Ainsdale and Formby. Hedgerows and rough ground behind the sea wall.
Identification
Long, slender body. Orange-brown above, white below. Black tip to tail — always, in all seasons. Faster and longer than Weasel, with that black tail tip.
Viewing & Photography Tips
Watch along fence lines and grass margins. They tend to move in a bounding gait and can be surprisingly bold — they'll often stop and investigate a still observer.
Conservation Status

Frequently Asked Questions
How do I tell a Stoat from a Weasel?
Size and tail are the key features. Stoats are noticeably larger — about the size of a small squirrel. The black tip to the tail is always present on a Stoat in all seasons, and is the most reliable field mark. Weasels are smaller, shorter-tailed, and have no black tail tip. Both have the same orange-brown above and white below colouring.
