The Maryland Ornithological Society (MOS) is a nonprofit, statewide organization of people who are interested in birds and nature. It was founded in 1945 and incorporated in 1956 to promote the study and enjoyment of birds. MOS promotes knowledge about our natural resources, and fosters its appreciation and conservation. The Society also maintains a system of sanctuaries to encourage the conservation of birds and bird habitat, and to help record and publish observations of bird life.

Local chapters throughout the state offer field trips, bird counts, and conservation projects for members and guests. Lively and informative programs complement regular meetings where members and guest speakers share their knowledge and expertise. Take a look at our mission statement to find out more about MOS.

Go Birdwatching

Birding

Birding can be as simple as watching the pigeons fly by your window or pausing to marvel at the chirping sparrows in the trees.

Photography

For wildlife and nature photographers, birds provide fascinating but challenging subjects to capture with even a long lens.

Priority Birds of Maryland

Fourteen Maryland birds are on the state’s endangered list, with habitat loss often the most likely cause. Another 60 birds or so are either threatened, in need of conservation, extirpated from Maryland, or considered rare. To highlight these species, educate the public and formulate responses to threats across all fauna DNR formulated the State Wildlife Action Plan.
