You can also protect birds on a global scale by helping to preserve their habitat. So keep your cats indoors and take steps to reduce the reflection from your windows. Long-term declines in bird populations are caused by loss of habitat. This happens here at home and on the birds' wintering grounds in other countries as well. It is illegal to shoot most birds or to disturb their nests.
Some states have a hunting season for game birds such as pheasant, ducks and quail.
A license is required. Fees from hunting help preserve bird habitat. In the U.S. the only birds that you can kill legally without a license are the Pigeon, House Sparrow and the European Starling. Farmers are permitted to kill blackbirds and their relatives if they are about to damage crops. If you find a baby bird , leave it alone or place it back in its nest.
