Florida Turkey Vulture - Cathartes aura and a massive Iguana

I sat for a couple of hours this morning in the hope that an Osprey would come and dive for fish in the the pool in front of me  but without success.  I have been told that they regularly fish in the spot at Whisky Creek but for the entire time that I sat waiting expectantly, a Turkey Vulture was in the trees opposite preening and sunning itself in the strong morning sunshine.  Eventually it took off to look for something to eat no doubt.  They are magnificent if not a little bit ugly and their plumage is really quite attractive to my eyes, not to mention their spooky looking bare face and strong hook beak.  I have just read that they are no way related to the Old World vultures but just resemble them because they feed and act in the same way.  a prime example of convergent evolution.  I am very fond of that phrase and quite often quote it, now I know of a good example.
