of 1980. Because only two observations were made out of approximately 100 field days, <br />the Trout Creek drainage is not considered to be important as a staging, breeding or nesting area <br />for sandhill cranes. <br />There are eight species, Least Tern (Sterna antillarum), Piping Plover (Charadrius <br />melodus circumcinctus), Mexican Spotted Owl (Strix occidentalis lucida), Lesser Prairie- <br />Chicken (Tympanuchus nallidicinctus), Gunnison Sage-Grouse (Centrocercus minimus), <br />Western Snowy Plover (Charadrius alexandrinus), Mountain Plover (Charadrius montanus) and <br />Long-Billed Curlew (Numenius americanus), that are not known to occur in Routt County. <br />These species aze not known to occur in Routt County, and therefore on site or adjacent to the <br />mine site, due to the lack of sightings and/or habitat. <br />There are eight species, Whooping Crane (Gros Americana), Southwestern Willow <br />Flycatcher (Emnidonax traillii extimus), Plains Sharp-Tailed Grouse (~mnanuchus phasianellus <br />~amesii ,Bald Eagle (Haliaeetus leucocephalus), Burrowing Owl (Athene cunicularia), Western <br />Yellow-Billed Cuckoo (Coccyzus americanus), Ferruginous Hawk (Buteo reealis) and American <br />Peregrine Falcon (Falco neregrinus anatum), that are either known to occur or likely to occur in <br />Routt County due to sightings and/or habitat. These species were not sighted in the 1979 to 1980 <br />study on site or adjacent to the mine site. <br />Whooping Crane preferred habitat is in mudflats around reservoirs and in agricultural <br />areas. The Whooping Crane is an uncommon spring and fall migrant in the San Luis Valley. It <br />is a rare migrant in western valleys; most records in Mesa, Delta, and Gunnison counties and a <br />casual migrant on eastern plains. The Whooping Crane is accidental in mountain parks in <br />migration and in summer. The habitat in Routt County does not eliminate the presence for <br />Whooping Crane but there has not been a sighting. <br />Southwestern Willow Flycatcher preferred habitat is dense willows, cottonwoods and <br />woodlands found along southwestern Colorado rivers and streams. This species is known to <br />occur in Routt County and is fairly common in abundance. <br />Plains Sharp-Tailed Grouse preferred habitat is in Gambel oak and other shrub lands <br />lacking conifers. Croplands and riparian areas aze also used, especially in fall and winter. Leks <br />are located in wet meadows, ridges and knolls, or recently burned areas. This species is known <br />to occur in Routt County and is uncommon in abundance. <br />2.7-20b Revised 11/06 <br />
