The picture of this Black-throated Blue Warbler was taken in Prospect Park, Brooklyn, NY with my CANON EOS7D and the Canon 100-400 mm lens. I was glad to have the extremely fast burst mode that is built into the CANON EOS7D when I walked right into a termite hatching in the park.
The birds were flitting around in a frenzy hardly ever stopping and I was happy to be able to keep clicking away keeping up with the action with the CANONEOS 7D. I purchased a battery power pack for the CANON Speedlite 580EXII which makes the flash recycle much more quickly in addition the having the flash unit stayed powered much longer which came in really handy for this particular type of shooting.
