Check out the Birder’s Guide to Maryland and DC to explore Maryland’s four distinct regions and find the best birding spots. Site descriptions have maps, fees, parking information, weblinks, facility summary, and, perhaps best of all, a site-specific bird checklist from eBird. Each of the sites has been thoroughly checked out and visited by MOS members to ensure the best birding experience. And our site list will continue to grow so please check back for updates.
