This didn't go thru initially so I'm re-sending it.

All

Saw the question regarding what species of fish might be able to take a grebe.  
My best guess is that the bird that was the subject of this query surfaced out 
of sight and likely wasn't taken.  If it was I can't say for sure what took it, 
 but I can eliminate several of the species suggested.

Alligator gar---doesn't occur in Wi.
Blue catfish-doesn't occur in WI...flathead cats are predatory but typically do 
not occur in L Mich....channel cats are generalist feeders plus water temps are 
too cold for them to be active yet.
Common carp-rarely predatory and certainly not equipped to deal with this size 
prey.
Snapping turtle-too cold for them to be active
Salmon---a grebe wouldn't fit their search image
Muskie---possible but this is an uncommon to rare fish in L Mich (except near 
Green Bay), so not likely
N pike---This is the only realistic possibility, but still unlikely

If anyone wants to know more about fishes,  the second ed. of the  Peterson 
Freshwater Fishes is now out (at least on line).  It includes 150 spp not in 
the first edition.  With regard to WI fishes, the most up to date reference is 
"WI fishes 2000: status and distribution" by John Lyons et al and available 
through WI Sea Grant.
