Something to crow about? Ravens' smaller cousins becoming more common in Yellowknife

Next time you want to blame a raven for a summer poweroutage in Yellowknife, befair. Itmay have been a crow.

They're becoming more common these days in the city, says bird watcher Bob Bromley.

"They're in our yard, they're in the neighbourhood," he said.

"They're flying back and forth from Joliffe Island to Old Town. They're nesting in the Willow Flats area."

Crows are migratory andBromley said he and other bird enthusiasts suspect the increase in sightingsis due to an earlier-than-usualspring and warmer summer.

"It's just an accumulation of sightings and comparing that over the years. They're coming back much earlier and many more of them."

It's not strange, he added, given the changing climate. And crows are adventurous, just like their raven cousins.

"They're big travellers," he said.

"That's why the magpie, which is a close relative of the crow, also moved in here in the early 1980s and now people see magpies all over the place."

Mistaking a crow for a raven is easy to do as they're bothlarge-sized black birds. But there are a few distinguishing characteristics.

Bromley saidyou can tell a crow by the sound of its caw and its smaller size about two-thirds that ofa raven.

"It's also got a relatively short, fan-shaped tailcompared to the raven, which is wedge-shaped, so that's probably the best thing if you get a look at them flying."

Bromley says crows are also entertaining becausethey're smart.

"Especially when they're out looking for food, they can get up to some amazing antics and fool other animals and even people."
