Here's a few quick tips that I use: Eagles are definitely day hunters, you will not see them in dim light or at night. Owls have blunt heads and your first impression is a small body relative to the length and breadth of the wings (like a bullet with wings too big for it). Eagles soar with their wings horizontal to the body, and from below it looks a lot like a paper airplane with squared-off rectangle wings, there's not much "point" to the wing tips. They are also very steady flyers. Vultures hold their wings in a V-shaped dihedral (looking at it horizontally), and that makes them pretty unsteady in flight, so you see them kind of tippy with any cross-breeze or wind change, dipping one wing or the other.
Here's a good short page on the basics of the three types of "hawks"

The following is very cool, an animated map showing the migration patterns and dates for your chosen bird, here I put in Red Tail Hawk (
@BY Bob and RC check out what PA looks like in early November). You might have to join ebird to see it? It is free. They have been collecting data from volunteer users and have gotten some really robust visualizations of it now.

I misspoke earlier - it's the Rough-Legged Hawk, not the Red-Shouldered Hawk, that for the Northeast is mostly north and we don't see it except seasonally
