geese and other fowl

On Christmas day, as we were headed out to the movies, we passed a school playground with about two hundred Canada Geese all facing the same direction.  DH pointed it out to me and told me they were there to sing geesemas carols.  I suggested that they were the grounds maintenance crew there to fertilize the grass and get rid of the slugs.  This is a very new agey school, so of course they would use the greenest methods possible, and if anyone has seen goose poo, you know how green it is.  We decided that both explanations could be simultaneously correct.  They could sing geesemas carols while they were fertilizing.    Let's see, what carols would geese sing?  These, of course, would start with "Oh Canada."  Then perhaps, ""We free wings," "Here we come a waddling,"   Would "TheTwelve Day of Geesemas" include six geese a-laying?  (two purple slugs and partridge . ..)

The next day, as we were on our way to the store, we passed a house with an apple tree in the front yard.  We had a freeze a while ago, then several warm days, then a good stiff wind which blew down a number of apple.  There was a family of geese feasting on the fallen apples and acting erratically.  I mean, it's hard to tell if a goose is staggering. But they would stand with head held high, sort of making little circles with it as if trying to get things to come into focus.  And one goose was trying to intimidate  a parked pickup truck.  My friends in Oz tell me that parrots get drunk and hold loud, raucous parties, where they to sing dirty songs but no one can remember the words.  I can just envision a parrot, lying on its back at the side of the road, feet in the air, crooning, "Shweet vi-o-letchsshhh, shweeter than all th rozess . . " over and over and over.

Do geese and parrots have hangovers?
