"Bird" watching at 30,000 ft. :-)
This "birding" experience actually happened about a month ago when I traveled by air to Denver, Colorado, and back. On the way out from Portland, I enjoyed having this Bald Eagle soaring out there to my right. (The stewardess referred to him as "Sarge.") On the return trip the Great Egret (I think she called him "Stretch.") kept pace with us.
