About DOS

The Delmarva Ornithological Society (DOS) includes over 350 members from 9 states. Our members come from diverse backgrounds but share a love of birds and an interest in protecting the habitats on which they depend. We sponsor many bird-related activities and trips around the region for birders of any skill level. 
The Delmarva peninsula comprises the state of Delaware and portions of Maryland and Virginia. Delmarva is characterized by the rolling hills of the piedmont to the north and the flat coastal plain to the south. Thousands of square miles of wetlands ring the peninsula, which is surrounded by the Delaware Bay, Chesapeake Bay, and Atlantic Ocean. 
The peninsula's many forests, fields, marshes and bays provide ideal habitat for many birds (over 400 species have been recorded here), and its role as a stopover point along the Atlantic Flyway makes the region crucial for many migrants, especially shorebirds.
