Glad to see the northern harrier again after a couple of months.
I suspect this is a juvenile male northern harrier from the eye color and white below. I may be wrong.
A very windy day today in Los Angeles. Hard to hold my lens still.
Canon 1D Mark IV, 500 F4, 2X III, f11, 1/2500s, ISO 1250, handheld.
LR3, CS5, Nik
Thank you all! Chasing him up and down the hills was no joke. I think my legs are still shaking. I tried the 500 and 1.4x combo quite a few times, but every time when I just climbed a hill and almost caught up, he flew to the next lightning fast and he just appeared too small in the viewfinder. So I decided to give the 2X III a try, provided the relatively good light.
