Why doesn't O'Reilly use parrots on its python books?

[Alex]

Given their venerable standing in Python lore, it surprises me that none
of O'reilly's python books have a parrot on the cover.  There must be
lots of types of parrots to go around, even if some O'reilly books
already have them.  And the python book could be distinguished by the
fact that its parrot is lying on its back with its feet curled up...

A really agressive looking rabbit would work, too.
