This place is tough to shoot without a 400mm or larger lens. I used a 300 and 2x on some and a 300 f2.8 on some. These are all blown up over 50%

Camera details: Canon 40D, Sigma 120-300 f2.8 Sigma 2X teleconverter. Light was good all morning, there were lots of eagles but only a few close enough to shoot. Eagles in the trees are in the parking lot, but back lit.
