While staying in Tofino last week, we saw several Bald Eagles. One took up its post near our cabin, keeping watch for an easy meal of fish from the inlet.
We know the plumage of the adult: evenly dark brown with a white head and tail. Males and females are identical in colour, and differentiated only by the fact that the female is 25 per cent larger than the male.
Plumage of an immature Bald Eagle resembles that of a Golden Eagle: a messy kind of brown with white streaks covering the bird from head to tail, until its fifth year when it becomes an adult. These photos show an immature Bald Eagle in flight.
