We were battling the wind this morning. It let up toward the end of our walk, but we hadn’t seen much so we decided to add McIntosh Lake to our trip. That was a good decision because a fish die-off was gathering all sorts of birds to the lake.
Bird of the Day – Bald Eagle – Haliaeetus leucocephalus – Boulder, CO
Wherever you find fish, including dead fish, you are likely to find bald eagles. It was the dead fish at McIntosh Lake this morning that attracted so many bald eagles. Most of the eagles we saw this morning were immatures of varying ages. It takes four years for a bald eagle to obtain its white head feathers and its head may appear a little smudged for two more years. After that time, its head will have the brilliant white head and tail feathers. There is no mistaking an adult bald eagle. Both sexes are similar and cannot be easily distinguished, however, the females are about 4% larger than males.
