I swear this little guy was toying with me, baiting me. He kept flying back where we were, but I couldn't get close. I only posted this, not because it's an example of a stellar bird shot, but because I was impressed with the quality even tho it was cropped to about 1/8th the original image. I certainly don't advocate cropping like this, but sometimes, you just can't get close enough and I was surprised at how well the 5DMKII handled this.
