These two were having a bit of a territorial dispute. The one up high was trying to horn in on the nesting area for the other guy and his mate. She casusally sat atop a tall pine while the two macho guys zoomed and dove at each other for a few minutes … before the interloper decided it was time to move on.

It must be truly wonderful as you capture the pics and give it a story line.
I have enjoyed it as i look and read each one. Fascinating
