Woodpeckers pose unique threat to homeowners as nesting season approaches

Some Calgary homeowners say they're plagued by incessant drumming as the northern flicker woodpecker, a protected species in Canada, attempts to drill its way into the stucco on the outside of their homes.

"Flicker woodpeckers, they come here every year and drill their holes and they cause a lot of damage. It's frustrating, very frustrating," said Harley Sanders, who is on the board of a seniors community on the outskirts of Calgary.
