Bald Eagle

Bald Eagles are common throughout the year in western Washington. This apparent pair perched in the Nisqually National Wildlife Refuge on 26 Decermber 2019. Bald Eagles are surpassed in size in North America only by California Condors. Bald Eagles are generally larger in the north and smaller in the south. Although the sexes look similar, females tend to be about 25% larger than males (Buehler 2000). This disparity is typical of most hawks, and, presumably makes aggressive males behave themselves at the nest. In this photo the bird on the left appears to be larger than the one on the right, so I guess the left bird is probably a female.
