Both of these guys are large birds. The Turkey Vulture which is common across the U.S. has a wingspan of up to 6 feet. The Andean Condor, the largest flying bird the world, makes the Turkey Vulture seem small with its wingspan of 10 feet. Both birds are scavengers, cleaning up the habitat. That's why they have bald heads – they stay a lot cleaner than if they had feathers when they are feeding and sticking their heads in places that are less than salubrious.
These photos were taken at the World Bird Sanctuary in Valley Park, MO, about 25 miles west of St. Louis. All the birds in the sanctuary have suffered some malady or injury that prohibits them from living in the wild.
Our visit gave me an opportunity to grab some really close-up shots of birds typically seen only from a distance. Unfortunately, since the birds are in cages, all the photos must be taken through the grid of wire fencing. While a bit of obstacle, this was not as problematic as the photo backgrounds caused by the cages.
