I find it hard to believe that a deceased, decapitated pelican lost its head to a rare, cold-water loving tiger shark who only prefers the head and bill, passing up the majority of the meat. I find it equally improbable that a propeller would decapitate a pelican that died of natural causes and not leave another mark on the carcass.

No forensic pathologist would list a cause of death without having the head to examine. It's an incomplete puzzle. I doubt the standards for a post-mortem on a pelican are that much looser.

The state and feds need to keep looking at this one. This is an unprecedented event that no one at the beach has seen before.
