Thanks for your comment. I have in the past few months started listing equipment with each picture but so far it has been too much work to do it for all of the older pictures. I was very close to this bird when I took this picture (almost no crop here). It was shot using the EOS 20D and EF 500mm f/4.5L USM and extension tube.
Some great birds in Texas. Are you from there?
It would be helpful to have the equipment used on the images displayed. I.e. in this shot what lens did you use? How close were you?
