You can put dead animal remains out with your regular trash for pick up by the Department of Sanitation (DSNY).
If you choose to put the dead animal out for collection, place it in a heavy-duty black plastic bag or double plastic bag. You must tape a note to the bag stating its contents (for example, "dead dog" or "dead cat"). Place the bag curbside for collection on your trash day.
To safely dispose of a dead bird, use plastic bags or disposable rubber gloves to put it in the double plastic bag. Make sure to wash your hands with warm soapy water afterward.
Rabid Animals
Do not put dead animals that may have been rabid in the trash. Learn how to identify rabid animals and report them to Animal Care Centers of NYC (ACC) on the Rabid Animal page.
