It’s a sight that’s almost impossible to believe, says artist and nature lover Sara Ross.

It’s the spectacle of thousands of crows arriving to roost at night on the banks of Still Creek in Burnaby near the Gilmore SkyTrain Station.

“It’s so incredible,” Ross gushed in a phone interview with the Straight. “It’s almost like the sky is a river of crows as they fly.”

On Saturday (February 2), Ross is leading a twilight bike ride to this roost that serves as home during the fall and winter for what she estimates to be upwards of 20,000 crows.

“We’re connected to the natural world in so many ways and the crows as they fly over every night are a reminder to us of that connection,” she said. “Where the crows roost at Still Creek is another place where we’re reminded of nature.

“Our ride is creative and we use play and laughter and curiosity to connect with the crows,” Ross added.

The activity is part of Reflecting Still Creek, a program from the Still Moon Arts Society that aims to connect people with the creek.

Those interested in joining the bike ride can choose between two starting points. One is at Lakewood Drive at 4 p.m. for a four-kilometre pedal. Or, outside the Renfrew SkyTrain station at 4:15 p.m. for a shorter, 2.5-kilometre ride.
