If you are a regular at Mosquito Lake State Park in Trumbull County, you may have noticed something different, at least for the time being.

Mosquito Lake is a great place to sit back and appreciate nature. But, Friday afternoon at the lake 21 News didn't notice one Canada Goose.

When normally, we're told there are dozens.

"It be packed full of geese, I mean droppings be everywhere but, I mean it's nice seeing them," said Montyne Johnson-Nall of Youngstown.

The Ohio Department of Natural Resources say they euthanized 160 of the federally protected birds because, despite signs that say "do not feed geese," people fed the birds -- which started becoming aggressive.

"If they're getting aggressive, especially with toddlers and stuff like that you have to be concerned about them. You have to put their safety first," said Dan Palmer of Cortland.

"I thought that was wrong, we're invading their territory. They go where food is sourceful for them, even though humans do feed them but, you should never have killed them," said Christy Huffman of Salem.

The O.D.N.R. says euthanization isn't a common practice but, one that was necessary because all other measures had failed.

Despite mixed feelings on whether putting Canada Geese down is the best solution, many agree the birds can make a mess.

Last year at this time, Mill Creek Metro Parks rounded more than 200 of the birds. At the time, they said each goose can make up to three pounds of droppings a day -- posing a risk to health and the environment.
