Does anyone know what the species of the flying eagle would have been in the 1840s in those parts. My kids have spied me playing it and are pestering me with daft questions.
We have golden and bald eagles. Juveniles can be hard to distinguish from each other, but both genders of adult bald eagles have the distinct white head.
There are also 17 hawks and falcons in the Pacific Northwest and the largest of them can easily be confused with eagles.

All that said, my money's on the bald eagle. It's so iconic that many other birds are overlooked in its favor.
