AOS: Donating to the Society

The American Ornithological Society's ability to conduct its important work is due in large part to the generous contributions by members and other individuals to our general operating fund and to gifts to the invested funds serving as our endowment. We invite anyone who cares about furthering the science and profession of ornithology, and about bird conservation, to consider making a charitable gift to AOS. Your gifts keep AOS going strong and support our global efforts to advance ornithology.

AOS has received a Platinum-Level Seal of Transparency from GuideStar in recognition of our commitment to financial accountability.


How to Give

Unrestricted Gifts of any size may be donated to the AOS general operating funds or our general endowment.

New Restricted Gifts to AOS may support an existing fund or become a new named, endowed fund. When funds are to be used to establish a new AOS program, such as a named award or grant, the donation must generate enough income to fully cover its costs. If you are interested in learning more about how to create a named, endowed fund, please contact AOS Executive Director Melinda Pruett-Jones at 312-665-7936 or
