By deductive reasoning, we have it narrowed down to two types. Northern Brown Snake and Eastern Garter Snake thanks to the Field Guide to Maryland's Herps section on the 27 snakes in Maryland.
So I have learned more about snakes since first moving to Georgia and participating in a required briefing about the area wildlife. So wherever you live, check out the resources available about the wildlife in your area. Many thanks to the groups that collaborated to provide this information and I appreciate how all participants are given credit on the site.
If you found a herp and aren't sure what group it belongs to, click on the silhouette to access the link to the field guide for that group. Amphibian groups in Maryland are salamanders, newts, frogs, and toads. Maryland reptiles groups include turtles, snakes, and lizards.
The Maryland Herpetology Field Guide is a cooperative effort of the MD Natural Heritage Program and the MD Biological Stream Survey within the Department of Natural Resources and their partners. We wish to thank all who contributed field records, text, and photographs, as well as support throughout its development.
The Maryland Amphibian and Reptile Atlas (MARA) is a five-year, joint project of the Natural History Society of Maryland and Maryland Department of Natural Resources. The information gained through your volunteer effort will be used to promote the conservation and protection of Maryland’s 90+ species of frogs, toads, salamanders, turtles, lizards, and snakes. You can submit your findings http://marylandnaturalist.org/submit-observation/
How do you discover information about unexpected backyard visitors? Is there a site where you can submit your observations? Do you know the difference between newts, frogs, toads, turtles, snakes, and lizards?
