INDIANAPOLIS - People are starting to notice starlings downtown. The birds try to roost in Indy during the fall and winter months.

"In years past, we've had up to 150,000 birds in and around the city," said Dan Young with the USDA Wildlife Services.

He, along with other local groups, is trying to stop the birds' arrival. Young said the birds aren't welcome because of all the problems they can cause.

"You get a large number of birds in an area, you get a large number of bird droppings, and that causes damage to buildings, not to mention the aesthetic value it affects," Young explained.

Young and his team will use a combination of techniques to scare off the starlings -- pyrotechnics, lasers and recorded bird warning calls. It's the same combination he's used for the past five years and is behind a loud boom you might hear in downtown.

Young and his team are expected to use their techniques in the evening hours until March.
