Phtotoxins/aflotoxins, same for the fish, normal happenings, but accelerated and en masse lately, it seems.

The birds diets are all similar, after seeing reports of massive ergot fungus blooms on the gulf coast I was wondering if we'ed see something like this from overwintering birds feeding on fallow fields in the SE area.

S'been my guess too till I hear a better explaination.
