These species should be considered if a <br /> water-related activity o use is proposed within the North Platte,South Platte or Laramie River Basins that <br /> may lead to downstream depletions of the river system in Nebraska. Because the project area is in the <br /> South Platte River Ba in, consultation with the USFWS Colorado Ecological Services Field Office is <br /> recommended to deter ine if impacts are anticipated and if mitigation would be required. <br /> The IPaC report also identified one additional migratory bird species with potential to occur at the site <br /> that is protected under the Migratory Bird Treaty Act (META) and Bald and Golden Eagle Protection Act <br /> (BGEPA). The Golden Eagle (Aquila chrysaetos) inhabits grasslands and forest habitat and often nests on <br /> cliffs or in large trees that offer unobstructed views of their surroundings. Cliffs and large trees are absent <br /> from the project area, making it unlikely that the project area would provide suitable habitat for this <br /> species. <br /> 5 <br />
