Dead bird pickup and testing is no longer done in the State of Maryland. The risk of West Nile Virus infection is considered universal in Maryland and further testing of birds is not necessary. The disease is not transmitted by birds and the presence of dead birds does not predict human illness or dictate mosquito control efforts.
If you find a dead bird, please dispose of it as follows:
- Wear plastic or latex gloves, or use a plastic bag as a glove.
- With your gloved hand, place or wrap the bird in a plastic bag and tie the bag securely.
- Dispose of the bag and gloves in an outdoor trash receptacle.
- Wash your hands with soap and water.
Please note that dead birds may also be buried. Sick or injured birds should be reported to the Maryland Department of Natural Resources Wildlife and Heritage Service, Nuisance Animal Hotline at 1-877-463-6497.
