So this one bid was how many times the size of the vultures that flew off?
I once saw 3 or 4 huge birds ridding a thermal above Phoenix, Az one summer day. Based upon the cloud height for that day they had to be 5 to 10
thousand feet up. I was using binoculars. I estimated these birds at 20+ foot wing spans. I thought that couldn't be right but, the more I observed
planes at the same height the more I felt the size was a correct estimate. I've watched a few large birds ridding thermals since then and it doesn't
compare to what I saw that one day. I even looked into the possibility of condors from up north soaring this far south but, I did not find anything
saying they come this far south. I am still baffled as to what I saw that day. I guess for now I still believe there are huge unknown birds out
I do know there is a condor in South America and I think they are larger than our condors.
