I have a strange year with absolutely no bullfrog tadpoles in the spring. Went into the fall with tons of them, nothing in the spring. Plenty of toad tadpoles. I still don't even see this year's hatch-lings so I am a little worried.

What we did have is several mink, and I can only assume those little buggers cleaned house under the ice when the frogs and tadpoles were in a stupor.

The fungus problems seem to not bother northern frogs/toads as much. I don't know why, could be the cold keeps the fungus at bay.

I did have a disease run through the pond killing off pickerel frogs two years ago, and that was sad, but I still see plenty of smaller ones hopping through the grass.
