dirk, I haven't noticed them going after any thing else unusual this fall/winter. In the spring they where chowing down on Horse Tails (a succulent prehistoric looking fern) I've been feeding them cracked corn this past month or so though and that has probably stopped them from getting too creative in their foraging. No adverse effects from the creeping buttercup roots. So far nothing seems to bother the geese to much. I woke up one early morning 6 or so weeks ago with them in a standoff with a raccoon, but the raccoons didn't seem to want to risk it and I loosed the dog on it. Haven't seen um since

Edit:
The geese are also the unwitting slaves of the dastardly cyanescen
mushroom. They spent all fall eating grass and tearing up roots and thrashing their beaks and feathery faces around in grass patches with this unwanted invader growing in swaths. I fear they have spread them all over as I have much
carbon in the form of snapped up branches and hacked up blackberry stalks laying around being slowly swallowed by grass.
