Apart from the sandhill crane, as discussed above, no Federally -listed or State -listed threatened or <br />endangered species would be expected to breed on the extension area. As previously noted, no nesting <br />habitat for the peregrine falcon exists on or adjacent to the area, the presence of the Western Yellow - <br />billed cuckoo has not been confirmed in potential habitat areas to the north and west, bald eagles are <br />solely winter residents or transients of nearby large drainages, and none of the endangered fish species <br />occur in the small tributaries in the Seneca IIW area. Ferruginous hawks may pass over the area during <br />migration, but this species typically nests in lower elevation rangelands, not in foothills shrublands. <br />The grizzley bear (Ursus arctos) wolverine (Gulo gulo) and Canadian lynx (Lynx canadensis) <br />potentially occur in the mountains of Northwest Colorado, but are likely extirpated from the area. <br />These species are wide-ranging, and it is possible that individuals might move through or reoccupy the <br />region at some point in time. <br />Based on comments received from the U.S. Fish and Wildlife Service (USFWS) in October 1998, SCC <br />committed to conducting a boreal toad survey in the spring of 1999. PRES contacted both the <br />UDFWS and CDOW to discuss the acceptable survey methodology and scheduling of the survey. <br />Three separate surveys were conducted: the first in late -April, the second in mid-May, and the last in <br />early -June. The three surveys, plus a nocturnal search, yielded no evidence of boreal toad presence on <br />the IIW South Expansion area. The final report, 1999 Boreal Toad Survey, is included in Tab 11, <br />Wildlife, as Appendix 11-2. <br />Andrews, R. and R. Righter. 1992. Colorado Birds.
