Thunder and crazy geese

Considering the very mild February we've had this year, I'm not feeling too bad that a trip to Florida that some friends and I had tentatively planned is not going to work out. It's feeling like spring can't be too far away, even including the really unexpected thunderstorms.  I'm evidently not the only being sensing that spring may be coming. The geese have been crazy around here, honking and squawking  and carrying on. I wouldn't mind this so much except, for some reason, they seem to fly in huge groups around my apartment building at midnight. Why midnight?  They always sound like they're having a great time. Who knew that geese had such a wild night life?
