Furry Friday: Weasel & Pika

Rob English took these photos in mid-June 2012 near the Highwood Pass.  He was looking for American Pikas, but so was this Long-tailed Weasel.









Furry Friday: More Weasels

You have to be amazingly lucky and very quick with a camera to get a photograph of a wild weasel. Glenn Alexon has managed to snap not one but two excellent portraits of local weasel species.

Here is a Long-tailed Weasel seen by the administration building at the Inglewood Bird Sanctuary on one of our Friends of Fish Creek birding walks, September 9, 2011.

Long-tailed Weasel

The most widespread weasel in the western hemisphere, Long-tailed Weasels are sleek, long bodied hunters 20-26 cm long, with a tail measuring half to two thirds of their body length. Summer coats vary from rich chocolate to rusty brown, with creamy white to yellowish underparts. Northern populations moult to pure white in winter, but their tail always has a black tip, regardless of coat colour. Southern populations do not change colour in winter.

Living from southern Canada to northwestern Brazil, these animals have the greatest habitat tolerance of any American weasels. They can be found in virtually all habitats, from Arctic-alpine to tropical, and are absent only from true desert and agricultural areas. They are most abundant in open woodland, brushland, and grasses and meadows near water.

Glenn has also managed to photograph a Short-tailed Weasel on the back of Sulphur Mountain in Banff.


Called Ermine or Stoat in Europe, Short-tailed Weasels measure 17-34 cm.  Their coats are rusty to chocolate brown with white undersides, and the tail has a black tip. Northern populations moult to white in the winter, but retain the black tail tip. In North America, they are smaller than the Long-tailed Weasel with a proportionately shorter tail, and the two species occupy the same geographic areas.

Found throughout the northern hemisphere in North America, Eurasia and Greenland, Short-tailed Weasels occur in a wide range of habitats from Arctic tundra to semi-desert, and sea level to 3,000 m. Unlike the Long-tailed Weasel, the Short-tailed can also be found on farmland and pasture, preying on the abundant rodent population.

More On Weasels

On Saturday the Friends of Fish Creek birders were walking on the path just outside the Inglewood Bird Sanctuary when we noticed another weasel – this time a Long-tailed Weasel – already in its white winter coat with a black tip on the tail.  These weasels are about eighteen inches long (45 cm), and about half of that length is the tail.  They are considerably bigger than their relatives, the Least Weasels, which are only about six inches (15 cm) long (see my recent post about Least Weasels here).

The weasel was aware of us, and it would duck behind bushes or into long grass to try to keep out of sight, while keeping an eye on us.

Occasionally he would run, then stop…

There were many Richardson’s Ground Squirrel holes there, and it looked like he was checking the holes for a meal…

One last run and stop…

…then he disappeared through the fence and we didn’t see him again.
