The anhinga is one of the few fish eating birds whose feathers are not
waterproof, so they have to spread their wings to dry after fishing.
I don't know about the cormorants. All I have heard of them lately is
that they have become a serious problem, being able to take as much
as three thousand dollars worth of catfish in a night from catfish farms
along the lower Mississippi. And the owners may not even harass them.
God bless the bleeding heart birders.
