It's funny you should bring up 2/75. That's where I saw my first bald eagle back in the 80's. They never got that close to us but I was amazed at how many there were in that part of the country. I'd grown up hearing about how endangered they were so I figured they could only be found in ones or twos.
Surprisingly, there is a
relatively decent concentration in the outlying areas around Ft Collins.
I've had bald eagles swoop down on us while floating the North Platte River in WY. They're usually up in a tree eyeballing us, waiting for the chance to steal a trout we caught. Thieving bastards!
Equally impressive are the ospreys that haunt the Poudre, N. Platte, and Green Rivers. Last year, an osprey couple had a nest above the Poudre River right where Prospect Road crossed the river on the east end of Ft Collins.
