The mess left by pigeons and the poor state of some buildings in Brigg town centre were discussed at Brigg Town Council's latest meeting.
Coun Jane Kitching warned: "The Conservation Area we are very proud of is deteriorating."
She raised general concerns about building maintenance, notably the upper floors.
Converting some of them to flats would be a welcome improvement, she suggested.
Coun Rob Waltham, who is the Leader of North Lincolnshire Council, said they would set up another audit of buildings. But he pointed out that these had to be "pretty bad" for legal action to be taken. What one person thought acceptable would cause someone else to take umbridge.
Coun Ann Eardley felt some of the upper storeys were being allowed to deteriorate. Owners should be maintaining the whole building "not let it go to rack and ruin."
Coun Penny Smith raised the issue of "perishing pigeons" in the town centre, with their droppings littering the paving.
She said it was time their numbers were controlled.
"There are far too many of them; they are just dreadful!" she complained.
Coun Sharon Riggall thought the council's maintenance man might be assigned to clear up some of the mess, while Deputy Town Mayor Coun Brian Parker complained that small children were having to walk through it.
Coun Chris Dyson recalled his days as a senior manager at Scunthorpe steelworks when huge flocks of roosting starlings were dealt with in various ways.
One company had removed 1,200 just at the heavy section mill!
"It's a matter that can be dealt with," he assured fellow councillors.
However, Coun Carl Sherwood pointed out that when North Lincolnshire Council looked to control pigeon numbers in Brigg a few years ago it had met with some opposition. The authority was also required to catch the pigeons. "This is what you are up against," he told his colleagues.
Coun Rob Waltham, the Leader of North Lincolnshire Council, said he would speak to environmental health staff about the problem.
N.F. ADDS: This is a topic Brigg Blog expects to prove a talking point for many people in the town. A few years ago when we reported a council debate about pigeons we were spoken to by an upset female resident who felt the pigeons had a right to be left alone. However, others who walk through pigeon droppings in the town centre take a very different view. What do YOU think? Pictured above: Pigeon "poo" in one of Brigg's alleyways.
