I fed the birds. Earlier I heard a woodpecker and managed to make visual contact, which is rare -- usually they hide behind branches. I also saw a squirrel. After I put the food out, some sparrows came to the hopper feeder.
EDIT 2/23/21: I replaced the dog dish under the basement drain pipe with one that looks more like a rock. It took a bit of extra digging to get it placed well, but I think it works.
