For our overseas friends GBH = Great-blue Heron. This fella was quite the poser as it preened and stretched for a long while merely 8-10 feet away. This full frame image was taken between preening sessions at a moment I thought the head angle was at a premium (it spent alot of time looking just ever so slightly away), and with the wind giving the long plume a nice curl :-)
Wonderfull and very nice, full of texture and color, the sharpness and the fact that it is a full frame makes it even better, I would've just darken a bit the BG to get more contrast especiallywith the chest feathers.
Congratulations! Nice one!
