areas on the ground conducive to nesting. Particular attention was paid to large trees, <br /> where circumnavigation of the trunk took place to locate any splay, feathers, pellets or <br /> predation evidence. Nests were identified as to species, based on nest configuration and <br /> construction material and location (position in tree, shrub, or ground). The Knox Project <br /> site was surveyed, with additional investigation of commercial and residential areas to the <br /> west and north of the project site that contained mature trees. <br /> RESULTS AND DISCUSSION <br /> Nest Survey <br /> The same two avian nests identified in 2018 were again encountered this year. The nests <br /> identified within the project site during the bird nest survey were both attributed to <br /> magpies (Pica hudsonia) (Figures 2-4) based on the geometry and construction of the <br /> loose twig and stick nests (Sibley, 2001, Bailey and Niedrach, 1965). Neither of the nests <br /> was found to be active during our survey. The second nest was determined to be <br /> damaged. Likely from seasonal weather. No recent repairs or nest building activities <br /> were evident at either nest. The nests were located in Chinese elm trees within the site. <br /> A wren or oriole nest was identified within coyote willows immediately adjacent to <br /> County Road 54G (old Highway 287) south of the project site. This nest was not active, <br /> nor was there evidence of new nest building or repair. <br /> A number of squirrel nests were identified within and adjacent to the project site, but are <br /> not discussed here. <br /> A subsequent on-line investigation of the Colorado Oil and Gas Conservation <br /> Commission web site map of special wildlife species (http://dnrwebmapgdev.state.co.us- <br /> /mg2012app/) identified bald eagle nests 1.76 miles east and 4.0 miles northwest of the <br /> project site. A golden eagle nest site was identified 2.1 miles northwest of the project <br /> site, and osprey nests to the southeast and northwest of the project site, ranging from 1.0 <br /> to 4.6 miles from the project site (Figure 5). <br /> Loveland Ready Mix Concrete Page 4 <br /> 2019 Knox Project Avian Nest Survey <br />
