Fun Facts Blue-gray Gnatcatchers sometimes beat large insects against a branch before consuming them.
In these cases, FEMA consults with us to avoid or minimize impacts to gnatcatchers. We acknowledge that in some cases a designation of critical habitat on private lands may provide some benefit to a species by highlighting areas where the species may occur or areas that are important to the species' recovery.
