John, I just used the reply button to Greg's post to ask the following question: Greg (or any others), do you have the approximate aspect ratio for: Vultur gryphus (Andean Condor) Gymnogyps californianus (California Condor) I've since found the aspect ratio for gryphus. It is about 6.86 Thanks, Jim P.S. Don't have a clue what was wrong with my previous message.
