## Abstract

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for the elfin-woods warbler (Setophaga angelae) under the Endangered Species Act of 1973, as amended (Act). In total, approximately 27,488 acres (11,125 hectares) in the Maricao, San Germ[aacute]n, Sabana Grande, Yauco, R[iacute]o Grande, Can[oacute]vanas, Las Piedras, Naguabo, Ceiba, Cayey, San Lorenzo, Guayama, and Patillas municipalities in Puerto Rico fall within the boundaries of the critical habitat designation. The effect of this regulation is to extend the Act's protections to the elfin-woods warbler's critical habitat.
