break the fences, surmount the obstructions and treat that place with the same lack of concern they feel has been shown them as residents and visitors to this place. Although the Recovery Plan for the California Clapper Rail and the Salt Marsh Harvest Mouse does not allege domestic pets or human contact as a limiting factor in recovery, the biological opinion focused on it. In the sections of the opinion referring to humans and domestic pets the helping verb goes from "is-shall-will," when describing the effects of the "best science" of natural predation, to "may- should-could," when subjectively describing supposed urban effects. The controversy at the Redwood Shores levee grew because the habitat was viewed in isolation from the rest of the Bair Island Complex. The controversy �� was focused solely on a small strip of a sloping levee wall. The assumed fragility of the Bi�d Island ecosystem was based in large part on the uncertain �� status of the Bai� Island Complex. It drove many assumptions. �� Levee Height and Refugia Now, with the acquisition of the Bair Island Complex, these governments can use a broader palette to paint the future together. They can spread their plans out and distribute any impacts over a broader geography. New perspective means that we can, with better understanding, address the wider relationship of Bird Island with the greater refuge. In its proper perspective, Bi�d Island is additional habitat for California Clapper Rail on Outer Bai� Island across Steinberger's Creek and adjacent to upland habitat and tidal refugia across Bay Slough. Clapper Rail survey data show a population on Bird Island of fewer than 10 birds. Since the rail data is gathered in the winter, we have no data to show if Bi�d Island is used as a rail nesting habitat. If rails are nesting at Bird Island, the results of that union (generally clutches range from 5 to 14 eggs) are not populating Bi�d Island. The Bi�d Island population, if a stable resident population at all, remains small. Bai� Island has a much larger population and will always be the source population for the birds of Bird Island. On Bird Island, chicks and young adults are most likely either lost to predation (Redwood City Marsh, in FWS ownership, contains low elevation perch opportunities for raptors from abandoned pilings) or relocation to the larger habitat on Outer Bai� Island. The levees at Redwood Shores were raised to a uniform 10 feet in order to protect public safety. Bi�d Island is marginal habit for the California Clapper rail. 28
