A Nova Scotia town that successfully chased away flock of 40,000 crows may have simply exported the problem to Charlottetown.

The crows were plaguing the town of Kentville in the Annapolis Valley 15 years ago. Eventually they tried the Phoenix Wailer, a device that emits random sounds - gun shots, distress calls, birds of prey calls - designed to frighten the birds off.

Bill Boyd, who was administrator with the Town of Kentville when it had the crow problem, said the Wailer worked.

"We still have lots of crows in the valley here. It's just that they're not roosting in the populated areas," said Boyd.

Now Charlottetown is dealing with thousands of crows roosting in a neighbourhood close to Victoria Park. Phoenix Agritech, the company that sold the wailers to Kentville, said the P.E.I. city may well be dealing with the same flock Kentville was.

"They dispersed around the Maritimes," said company owner Bruce Blacklock.

"One flock went to Berwick, and they purchased two wailers, and they moved on. And some went to Antigonish, and they bought a mobile wailer. Some ended up around Truro, but not in an area that's really bothering anybody. And no doubt, some went to Charlottetown."

Charlottetown council has experimented with the wailers, and it plans to make a decision on whether to continue using them by the end of the month.
