C.Barbette, and That is not the role of the Recovery Team provided for in the Act. As stated earlier, the energy needs of birds during molt is high.

Consequently, we have determined, based upon the likelihood that birds do not normally molt in the excluded area, and the low level of eider use received by the excluded area, that the excluded areas are not essential to the conservation of the species. Models with ΔAICc ≤ 2 are considered to have substantial levels of empirical support (Burnham and Anderson 2002). In addition to having the lowest mean temperatures, the winters of 1975 and 1976 had the highest number of extremely cold (lowest 5%) days. documents in the last year, 1424 This prototype edition of the M., Organic deposition and benthic biomass in this area have declined steadily since the late 1980s. We believe that special management considerations and protections may be needed for the essential features (constituent elements) found within Unit 1, primarily because lead shot present in the environment poses a continuing threat to the species. While every effort has been made to ensure that Waters within this zone are usually brackish. Unit 3 includes the waters of Norton Sound east of 162° 47′, excluding the indicated waters within Norton Bay. This final determination does not constitute a major Federal action significantly affecting the quality of the human environment. J. R., Comment 36: One respondent pointed out that critical habitat designation will result in the need to reinitiate section 7 consultation on projects on which consultation has previously been completed. Because of the potential for impacts on other Federal agency activities, we will continue to review this action for any inconsistencies with other Federal agency actions. Spectacled eiders typically winter south and southwest of St. Lawrence Island in the central Bering Sea; they wintered in the same place in 4 of the 5 years since the discovery of their wintering area. 1361-1407; 16 U.S.C. Food habits of North American diving ducks. Although overall benthic biomass (quantity of organisms living on the sea floor) in this area is thought to be lower than in other parts of Norton Sound, the abundance of large gastropods (e.g., snails, which are presumably a spectacled eider food item) is higher in this area than elsewhere (Springer and Pirtle 1997). For these reasons, all should understand that critical habitat designations do not signal that habitat outside the designation is unimportant or may not be required for recovery. Spectacled eiders are diving ducks that spend most of the year in marine waters where they primarily feed on bottom-dwelling molluscs and crustaceans. The ice parameter number of days in winter with ≥95% ice concentration and the weather parameters temperature and average wind speed in spring were more important relative to other variables (sum of AICc weights: number of days in winter with ≥95% ice concentration = 0.16, average wind speed in spring = 0.77, average minimum temperature in spring = 0.68).
