Shooting eagles in Squamish, British Columbia requires several things:
1) Long lenses.
2) Lost of light or faster lenses than I can afford.
3) A big cushion to sit on, as your butt gets cold and sore sitting on rocks for 4 hours.
The following were shot with a Canon 1D MkII + Sigma 50-500 + 2x extender at 1600-3200ISO due to low light.
