A to B – Arctic to Burnaby

While our fantastic stretch of sunny weather hasn’t quite been replaced by Arctic conditions yet, the constant, lashing rain is a reminder we really are in October, and frost and snow may not be too far ahead for us.

Big changes in weather often signal changes in our birds too. In late summer and fall, many leave us for more southerly locations, while others arrive here on their migrations, sometimes staying for the winter, and sometimes to stop-over, fuel-up and move on.

On Saturday morning at Deer Lake another harbinger of winter arrived, and this time the message was straight from the Arctic. A beautiful Rough-legged Hawk, a relative of our resident, breeding Red-tailed Hawks, stationed itself on a tree at the east end of the west meadows at Deer Lake, intently scoping the long grass for voles and mice.

In absolutely pouring rain, getting a good picture can be a little tough, and the one above shows the not quite satisfactory result. However, rough-legs are a rare sight in our parks, more often spending their winter around Boundary Bay, Delta.  Interestingly, this bird is using exactly the same small meadow that the last rough-leg that I saw in the park many years ago used.

The habitat here is likely similar in appearance to its Arctic tundra haunts, where it also hunts rodents, including those cute lemmings. As I’ve noted before on this blog: everyone has to eat! The Rough-legged Hawk is a really cosmopolitan species. Breeding on tundra around the whole Arctic – usually on cliffs, promontories, bluffs and other high outcroppings – it moves south in winter in Asia and Europe, as well as here in North America.

And in case you were wondering, the name ‘Rough-legged’ refers to its feathered legs, which are an adaptation to its cold climate home.

The bird was still present Saturday afternoon, and may hang in for a while. So take the time and see our Arctic visitor to Burnaby. It’s as easy as A to B.
