This is Sushi, a rather large, rare shoebill stork. He enjoys visits from people--but is very formal. You can only approach if you know the rules as you will see in this video posted by Mark Dudley Photography on August 26, 2016.
It is rather like approaching a king. You must bow with respect. If you don't, Sushi will fly away. It is thought that there are less than 5000 of these magnificent birds in existence, which is quite sad. Sushi and his kind are remarkable, beautiful creatures--and worthy of a bow showing respect.
