## Abstract

We, the U.S. Fish and Wildlife Service, are delaying the effective date of a final rule we published on January 15, 2021, revising the designation of critical habitat for the northern spotted owl (Strix occidentalis caurina) under the Endangered Species Act of 1973, as amended (ESA) (January 15, 2021, Final Rule). In addition, this action opens a 30-day comment period to allow interested parties to comment on issues of fact, law, and policy raised by that rule and whether further delay of the effective date is necessary.
