This spring, three pair decided that my pond was a good place to raise their goslings. Our pond is left wild and can be seen from the road so everyone enjoyed the brief glimpses of them. When a car would stop on the road, all three families would glide to the other end around a bend. Anyway, they grew up fine, eating our neighbors new corn as it came up. (He was understanding. ) The last time we saw them the babies were almost as big as the adults, but now they've all gone. I thought of disease, but Roger said there is no sight of corpses and I'd think that they were pretty big for predators to get all of them.. Do they move on after the babies have grown?
