resistence of raptors

[(Alex Appleman)]

Following on from Shane Raidal's commemts; raptors are hardy critters and also 
intelligent.  There is evidence in North Queensland of black kites preying on 
the dreaded cane toad, flipping them over and feeding the legs and soft 
underbelly to their chicks, avoiding the poison glands.  We can only assume 
that the kites ate poison in small doses, identified which part of the toad was 
toxic
and are teaching their offspring how to avoid them.
