I agree, Red Tail. The thing about red tailed hawks is they have so many morphs. They cover most of north america, however as you move from region to region, the feather coloring changes...some are very dark, some are midtoned, some are very light. Some are more "spotted", some are very solid colored. Some have deep red coloring in their tails, some have light red.
You also have to contend with the juvi morphs, which adds another few varieties. In some regions, like where I live in Colorado, you get migrating red tail hawks, so their diversity here is very high, and it's often impossible to figure out if you have a red tailed hawk, or some cross between a red tail and some other species, or some other species entirely.
