What is this, the third grade?

'Pigeons frequently perch around the building and poop on walkways and tenants' cars. The birds have generated enough complaints to prompt property manager Transwestern Commercial Services to try to get rid of them. The commercial real estate firm has sought help from a contractor that claims it is 'using fully safe methods to remove the birds,' Transwestern spokeswoman Sandra Porter said.'

How about 'leave excrement', or 'drop feces'? Poop sounds like something a kid would say.
