Biological Survey is a non-profit organization based in the Hudson Valley made of a network of scientists, nature enthusiasts, and concerned citizens. Biological Survey is dedicated to the preservation of wildlife  in the area focusing primarily on bald eagles. We share information with the Endangered Species unit of the Department of Environmental Conservation and also the public school system, educating students about the Hudson River and its resident and non-resident eagles.

We support the responsible educational concept of Environmental Planning guiding the balance of nature and economic growth. Any donations to Biological Survey are tax deductible and will go directly towards the study of our local bald eagles, thus enhancing our abilities to help the eagles chances for habitat procurement.

If you would like to contact Biological Survey to tell us of your own local bald eagle sightings, get organization information or to give a donation please call us at (845)758-4331. You can also email us here
