b. Great Palm Cockatoo
The Palm Cockatoo (Probosciger aterrimus) is distributed in rainforests and woodlands of New Guinea and northern Queensland, Australia. It measures around 55-60 cm in length and weighs between 500-1,000 g. It is a distinctive bird with a large crest and has one of the largest bills of any parrots (only the Hyacinth Macaw's is larger). The bill is unusual as the lower and upper mandibles do not meet for much of its length, allowing the tongue to hold a nut against the top mandible while the lower mandible works to open it.
