Sorry to disappoint but the bird is alive and well and living in northern S. America and Central America.
Note wing claws which had originally caused the evolutionists to get over-excited!
Add this to the extensive list of 'things which we were taught in school about evolution which have proved to be absolute bunkum'.
It is called 'hoatsin' [spellings vary] and smells appallingly of poo - in common with some of the evolutionary hypotheses which abound!
