Sulphurcrested Ofile Cockatoo

The sulphur-crested cockatoo, resplendent in its bright-yellow headdress, is equipped with a powerful, nut-cracking bill and highly dextrous feet.


Shape of the feet lets the cockatoo manipulate food items with its toes. It also uses its feet to pick up and inspect unfamiliar ^ objects.

Bill is powerful for cracking tough nuts and sharply hooked for slicing fruit. It's also used like delicate tweezers, along with the fleshy, mobile tongue, to position food ready for crushing or swallowing.



Wings are broad and powerful. The cockatoo flies with rapid bursts of shallow wing beats between alternate glides.


Two toes face forward and two backward. Each toe has a long, curved claw.
