Now that I live in a house, I keep the bird baths full, so as to keep our local birds from dying of thirst during the long hot summers.
All summer long, or at least when I visited, my dad's backyard was full of birds. Robins built a nest and raised some babies in one of the dogwoods, wrens raised a couple of broods in the birdhouse, and the feeder and the bird bath constantly attracted cardinals, goldfinches, house finches, chickadees, and, of course, the ubiquitous sparrows.
When I viisted over Labor Day Weekend, it was as if they all had vanished. Not just from my dad's backyard, but from his entire neighborhood! Not a bird to be seen! Not even a starling!
WTF?
Perhaps they had all gone to the country. The local newspaper that weekend had a big story about the harvest coing in a couple of weeks early because of the dry weather, so maybe the pickin's had become better out in the county instead of in my dad's backyard. Who knows? Last week Dad told me the cardinals have returned.
