You are here: Home - Sanctuaries


As a member of the Maryland Ornithological Society, you have the distinction of being part-owner in a large and diverse sanctuary system. Nine MOS sanctuaries are located throughout the state from Garrett County in Western Maryland to Somerset County on the lower Eastern Shore, protecting a total of 2,187 acres. They range in size from 8 acres to 1,570 acres. They protect the flora and fauna of woodlands, fields, swamps and marshes and provide places where MOS members can go to view nature and do research. Additionally, there are two MOS-affiliated sanctuaries protecting another 600 acres.

This web page has been designed to inform you of their history, locations, the habitat that they protect and their availability for visitation. Each sanctuary has been placed into one of four categories according to type of usage.

 Click the link below for directions to each of our sanctuaries 

(For those not familiar with using Google Maps) If you click the open rectangle at the top right of the map display, a larger map will open showing the sanctuary names associated with the numbers. Either click on one of the numbered blue circles, or on one of the names, and the name of the sanctuary you have chosen will appear in a red background. To its right will be an arrow in a white diamond. Click that and Google Maps will open for that destination. Enter the address of your starting point at the blinking cursor on the left, and Google Maps will give you step-by-step directions below and show your route, sometimes with alternatives, on the map.

If you decide to visit a sanctuary, there are procedures to follow. The section on Sanctuary Visitation Regulations applies to all sanctuaries. Under each of the four categories above are listed the regulations that apply to that category only. There are also Regulations for doing Research or Collecting Specimens on the sanctuaries.

Private Sanctuary signs are available for landowners who register their land as a wildlife sanctuary with MOS.

The information contained here should be all you need to get started in visiting your sanctuaries. Enjoy them and good birding!
