Page 3 protection under the Endangered Species Act (Act), it is within the spirit of the Act to consider project impacts to potentially sensitive candidate species. Additionally, we wish to make you aware of the presence of Federal candidates should any be proposed or listed prior to the time that all Federal actions related to the project are completed. Federal Candidate Species Ferruginous hawk Loggerhead shrike Columbian sharptailed Roundtail chub Penstemon mensarum Buteo reaalis Lanius ludovicianus grouse Tvmpgnuchus phasianellus columbianus Gila robusta Grand Mesa penstemon The ferruginous hawk is the largest buteo in North America and is a category 2 listing candidate. It is a common summer resident of grasslands in Rio Blanco County, occasionally nests in pinon-juniper woodlands, and feeds on small mammals such as prairie dogs and rabbits. Human disturbance near active nest sites can result in nesting failure. A petition to list the ferruginous hawk was recently determined unwarranted by the fish and Wildlife Service. However, there is a need to continue monitoring the status of this candidate species. The loggerhead shrike is a category two listing candidate species.' The shrike may be found in a variety of habitats below 6,000 feet elevation, including riparian areas and pinyon-juniper woodlands. The shrike is a fairly common Sumner resident and spring and fall migrant in Colorado. The loggerhead shrike may feed on large insects, small birds, or mice. The loggerhead shrike has shown significant population declines over much of its range. It has been extirpated from some areas in eastern Colorado, but appears stable in western Colorado. It is a rare to uncommon winter resident in western valleys north to Mesa County and on the southeastern plains north to the southern E1 Paso County. The loggerhead shrike has also been identified by the Partners in Flight international joint venture as a neotropical migrant worthy of attention. The columbian sharptailed grouse is a category two listing candidate. It is a local resident in Routt and eastern Moffat counties, with smaller populations south to Montezuma county. The grouse is associated with shrublands and cultivated fields between 6,000 and 7,500 feet elevation. Populations have declined due to impacts to habitat. This grouse has declined in numbers and distribution throughout its range, and has been extirpated from California, Nevada, and Oregon. Its remaining stronghold is in western Colorado. Grouse are entirely insectivorous. For additional information on the species biology and distribution, contact Clait Braun with the Colorado Division of Wildlife in Fort Collins (303-484-2836). The roundtail chub is a category 2 listing candidate. It is a native of the Colorado River basin and may reach 18 inches in length and weigh up to two
