My spouse and I spent the morning of the 4th of July on the Wabash River north of Terre Haute, looking for wildlife and hoping to see some the of recent eagles that have returned to the river. Growing up in Indiana for over a half century, I never saw a native Hoosier eagle in Indiana, anywhere, although they definitely were here in Indiana when the Europeans first arrived.
I am happy to say that bald eagles are definitely home grown Hoosiers, now, with several eagle nests that I know of within 30 miles or so. Yesterday, we saw several mature and juvenile eagles watching the river as we floated by them.
A brief note about standing and photographing with 400 or 600mm lenses from a small tippy boat in a river with a 4 knot current. I find that it can be challenging to keep the subject within the frame handholding in this sutuation,( that's a sardonic understatemant since text doesn't always convey my implied meaning well ) and that was certainly true yesterday morning.
Fast shutter speeds, and their associated high ISOs were required. Shooting lots of frames in the brief time availble for a shot helps a bit, as the scene continually changes as the boat floats downriver, tips and rolls, and the eagle reacts to the wind, the water, and the new presence floating down the river. On a side note, the eagles actually seem very used to seeing boats, the howling warning horn of the outboard starting controls do not seem to affect them at all - they really don't seem to react to what one might think would disturb them. Kind of like hawks I have seen sitting on power wires hanging over 4 lane divided highways full of traffic as they search for prey in urban areas.
The first eagle of the morning was a mature bald eagle in a maple tree, that looked like eagles had used that branch often, from the white coloration of the eagle waste on it. Shot with a 1Dx MkII, Tamron 150-600 at 600mm, f 8.0, 1/1600th sec, ISO 6400
