Xavier and Oswaldo,
461 is unbelievable. I had hoped for 400 when I signed up for tour but that was wishful thinking. Even more remarkable is cost per bird. With both airfares added to tour cost it works out at jut under $10/bird. I read somewhere that most tours average around $50 per bird. What a bargain we had!
