After you have reported a dead bird, you will be contacted to determine the condition of the bird and if it is suitable to be picked up for West Nile virus testing. All dead bird reports are used for surveillance purposes and are extremely valuable to us even if the bird is not submitted for testing.

If you have not been contacted within 24 hours of your report, you may safely dispose of the dead bird in your trash. There is no evidence that West Nile virus can be acquired by handling dead birds, but it is best not to handle the dead bird with your bare hands. Use gloves, a shovel, or a plastic bag to place the bird in a trash bag for disposal. Please DO NOT freeze dead birds. West Nile virus is transmitted by mosquitoes, so the best way to protect yourself from West Nile virus is to avoid getting bitten by mosquitoes. For more information, please review our FAQ area regarding submitting dead birds.

To report a dead squirrel, please call 1-877-968-2473.
