CHARLOTTE, N.C. -- Three-hundred birds flew into the NASCAR Hall of Fame building Tuesday night in Charlotte, according to the Carolina Waterfowl Rescue.
Many of the birds are dead or seriously hurt after flying into the Hall of Fame at about 11 p.m.
Their rehab team sprung into action to help care for the birds, but they say more help is necessary.
Around 100 of them died, 100 more were seriously hurt with broken wings and other injuries and 10 had to be euthanized.
Around 100 more appeared "stunned" and hopefully are going to be released in the coming days, Carolina Waterfowl says.
The birds are chimney swifts that need to be fed worms by hand.
"It's an expensive endeavor but these birds are an incredible contributor to our eco system and eat hundreds of mosquitos a day," the rescue says. “I’m not sure how we will manage but where there is a will there is a way. Tonight we just need some sleep.”
The group listed multiple ways people can donate to help care for the injured birds:
