Through the distant trees, I spotted a shadowy shape in the early morning hours last week at Occoquan Bay National Wildlife Refuge. Was it a large bird or simply a malformed tree? It is a little embarrassing to admit it, but I often find myself taking photos of odd-shaped branches or leaf formations, thinking they might be birds.
In this case, though, it turned out to be a bird. When I zoomed in to get a closer look, I initially thought it might be a hawk, but the more I stared at the hazy form, the more I realized that it was almost certainly an immature Bald Eagle (Haliaeetus leucocephalus).
It takes almost five years for an adult Bald Eagle to develop its signature look, with its yellow beak, light-colored eyes, and white head and tail. In the interim the eagle’s plumage is flecked with white, rather than being a solid dark color, and the beak and eyes are darker than they will eventually become. Experts can tell the age of an immature eagle on the basis of its plumage pattern—I am definitely not an expert and would guess from what I have read on-line that this eagle is probably about a year old or so.
Although I was a long way away from the eagle, it seemed to sense by presence and took off shortly after I spotted it. As the eagle flew away, I was able to capture an image with a view of the mottled pattern of the feathers on the underside of its wings and its dark tail feathers
