AOS rejoins the OC

The Ornithological Council is pleased to announce that the American Ornithological Society will rejoin the Ornithological Council, effective 1 July 2026.

The American Ornithological Union and the Cooper Ornithological Society were founding members of the OC during its formation in 1992; the AOU and Cooper merged in 2016 to become the American Ornithological Society. AOS chose to leave the OC in 2020, but has now decided to rejoin the consortium. The AOS Bird Collections Committee proposed the renewed partnership, which was approved recently by the AOS Council and the OC Board of Directors.

Starting in July, individual AOS members will once again be able to receive one-on-one permitting support and guidance from the OC. While many resources provided by the OC are freely available, such as permitting information on the website (www.BIRDNET.org), our Import Guide, and the Guidelines to the Use of Wild Birds in Research, individual assistance is only provided to members of the OC societies and to staff of our Supporting Members.

The OC welcomes the AOS back and looks forward to working together to support the ornithological community.
