Among the most important questions an American can ask is, "What should I do when my goose's head falls off?"
The first step toward resolution is, don't panic. Think back on lessons in basic ornithology. Unlike most birds, geese are not hatched from eggs, nor do they have articulated skeletons. They begin life as wads of rebar (short for reinforcing bar, used in masonry structures), around which concrete is cast. One end of the rebar is drawn up and forward to support a neck and, for maybe 20 years, a head.
What with rain, drought, irrigation, worry, etc., heads tend to crack and crumble, then fall off. Look in the mirror; watch for the signs. We're not so different from other animals --like geese. However, much can be done. First step is to find up any pieces in the dirt that can still suggest a cranial contour --it's what brain surgeons do, I think.
Let the beak dry, smooth it with sandpaper, then remember when to stop --some folks sand things down to a fraction of their original size, a strange and regrettable enthusiasm. Then wait, go live happily and thoughtlessly a few days until everything dries. Afterwards, decide whether you want to seal the patch with goose details --and no, you won't capture the mischief in their beautiful eyes, as I had to admit to myself-- or reintegrate the repairs with color of concrete. I got into the pumphouse and found a 30-year-old can of gray primer.
Did the trick.
