Birds of a feather flock together, and in some areas of Nashville the groups of starlings and robins are so large they're causing a nasty mess.
And it turns out there's a good reason for it.
"I wish I had a hose," said David Gibson, a resident in the Sylvan Park neighborhood.
Gibson's car has been bird bombed and badly needs a wash.
"Super gross - just not what I want it to look like," Gibson said.
For Gibson and his neighbors in Sylvan Park, there's really no getting around the robins and their droppings.
"It's wreaking havoc around here on cars, on the ground and everything like that," said Richard Kirk, wildlife program manager with the Tennessee Wildlife Resources Agency.
The birds flew in more than a week ago, and bird experts say it's a winter phenomenon.
"Some species of birds will fly far South as they need to go to get warmer weather and food," Kirk said.
But recent mild weather in Middle Tennessee is just what they're looking for. Robins, starlings and black birds move in massive flocks. They travel in numbers for defense, even creating synchronized patterns that can number in the tens of thousands.
There are several known large roosts in Nashville. The Eastside, Hillsboro Village and even Vanderbilt University has had bird problems before.
"It makes me feel better to know other people's cars look similar to mine," Gibson said.
But if they choose to take over the trees in your neighborhood, take cover.
Experts say the massive flocks can be hard to break up. Last year, crews at Vanderbilt even tried using fireworks and cannons to scare the birds away.
The flocks should disperse as soon as the weather starts to get warmer up North, which is usually in late March.
