Every year MOS hosts an annual conference for MOS members and the general public. Conference locations vary from year to year to sample Maryland’s great diversity of species and habitats. Usually these are held in the spring or early summer when birds are migrating or nest building but are occasionally held in August to catch the shorebird early migration southward or in February in Ocean City to see the wintering waterfowl. Recent conferences have been at: Washington College, Ocean City, WISP Resort, and Salisbury University. Please return to this page to see advanced notice of conferences, pin contest announcement, followed by details and online registration.
