# SUPPLEMENTARY INFORMATION:

## Background 

                    The coastal California gnatcatcher is a small, insect-eating bird with dark blue-gray plumage above and grayish-white plumage below. The tail is mostly black above and below. The male has a distinctive black cap which is absent during the winter. Both sexes have a distinctive white eye-ring. The coastal California gnatcatcher is primarily restricted to sage scrub and scrub habitats found in coastal southern California and northwestern Baja California, Mexico, from Ventura and San Bernardino counties, California, south to approximately El Rosario, Mexico, at about 30° north latitude. The once-common species was federally listed as threatened in March 1993, due to habitat loss and fragmentation resulting from urban and agricultural development, and the cumulative effects of cowbird parasitism and predation (58 FR 16742). On February 7, 2000, we published a determination proposing 323,726 hectares (799,916 acres) of sage scrub and scrub habitats as critical habitat for the coastal California gnatcatcher in the                     **Federal Register**                     (65 FR 5946) pursuant to the Endangered Species Act of 1973, as amended (Act). Critical habitat is proposed in Los Angeles, Orange, Riverside, San Bernardino, and San Diego counties, California, as described in the proposed determination.                 

                    Section 4(b)(2) of the Act requires that the Secretary shall designate or revise critical habitat based upon the best scientific and commercial data available and after taking into consideration the economic impact of specifying any particular area as critical habitat. Based upon the previously published proposal to designate critical habitat for the coastal California gnatcatcher and comments received during the previous comment period, we have prepared a draft economic analysis of the proposed critical habitat designation, which is available at the above Internet and mailing address. We have reopened the comment period at this time in order to accept the best and most current scientific and commercial data available regarding the proposed critical habitat and the draft economic analysis. We will accept written comments during this reopened comment period. Previously submitted oral or written comments on this critical habitat proposal need not be resubmitted. The current comment period on this proposal closes on July 31, 2000. Written comments may be submitted to the Carlsbad Fish and Wildlife Office in the                     **ADDRESSES**                     section.
