|The official Service logo is restricted to use on
official sites. The official logo should not be used on non-official sites - not even as a link back to a
Service Web page.
Instead, we suggest you make a text-only link, such as "U. S. Fish and Wildlife Service." If you are already using the official logo without permission, we have some public domain (copyright-free) graphics on this page that you can substitute for the official logo.
In addition, see the Image Library for other images that may be suitable as a graphical link.
