RE: Bird Botulism?

One other area that I'm aware of information would be the WDNR. I beleve a number of years ago the the Horicon Marsh had a botulism out break that killed geese and other waterfowl.

Subject: Bird Botulism?


I have a question?

A few summers ago we started noticing gulls dying in particularlly high
number in August at a beach we were studying.  These birds at first seemed
'drunk' at first, then began losing coordination and equilibrium.  They
would then lose the ability to walk and would soon died thereafter. That
was the same time old masses of anaerobic Cladophora was accumulating on
the beach.  Lately, I've been wondering if these bird might have picked up
some botulism from the algal mats.  As anybody else noticed this
phenomenon? Can you remember if it was coincidental with these anaerobic
mats or during this season?   Would you be on the look out this summer for
it, especially if you have big mats of Cladophora?  Let me know what you
think.
