Some farmers enforce their property rights with shotguns; others use feral cats, cannons, balloons or plastic owls. If they don't, birds can eat them into poverty.
This is the time of year when sparrows, starlings, pigeons and other overwintering fowl start making a pest of themselves in barns and feedlots. Feed lines in dairy barns are black with birds and the backs of the cows are often slick with their excrement.
An adult starling, according to some reports, will eat one-and-a-half times its body weight in feed per day if given the chance. Wintering flocks numbering 2,000 birds will consume a ton of feed a month or more.
