Nesting instinct. Nesting behaviour refers to an instinct or urge in pregnant animals caused by the increase of estradiol (E2) to prepare a home for the upcoming newborn(s). It is found in a variety of animals such as birds, fish, squirrels, mice and pigs as well as humans.
Nest, eggs and young. Like the Osprey and the Bald Eagle, the Golden Eagle is a champion nest-builder, at least in terms of size. Golden Eagles construct a huge platform of sticks, which they line, or pad, with thinner branches and even hair and grasses.hese large birds sometimes build their nests in trees or might use man-made structures, such as an electricity pylon. In Alaska, some Golden Eagles were documented nesting on the ground., but most often they nest on large ledges on cliff faces. Golden Eagles may use the same nest over many breeding seasons.
Golden eagles are protected by the Migratory Bird Treaty Act in Canada, the U.S., and Mexico, and by the Bald and Golden Eagle Protection Act in the U.S. (Kochert et al. 2002:29). In Oregon, golden eagles are designated as protected nongame wildlife by Oregon Department of Fish and Wildlife (2010).ounted. Golden eagle nests or golden eagles were found at 278 (85.8%) of 324 historical potential breeding areas surveyed and no nests or eagles were found at 46 (14.2%), suggesting a long-term loss of potential breeding areas of 14.2%.
