Technically ‘chumming is a fisherman’s term -- to throw out bits of chopped fish as bait. Instead of bits of fish for fish I put out water to attract birds. We were camping in the high desert. No surface water for about ten miles. We’ve camped here off and on for over thirty years. There used to always be a leaky faucet .... but no more. Maintenance has done an excellent job of making sure no water is wasted. Whenever anyone uses a campground faucet, the birds hear and come flying in for the few sips that land on the concrete. At least there were birds in the area. In many areas of this arid high desert birds are scarce.
I took the liberty of nestling a pint of water amongst some rocks. Directly over my pint of water I hung a sandwich bag filled with more water and with one pin hole pricked into the bottom. The birds came immediately. As long as I kept water in the tiny pool, it was never quiet for more than a few minutes. First came the robins , the bullies. they did their best to monopolize the pint of water.
.... so pleasant sitting at the picnic table in the Indian summer sun and watching one bird after another crowd around and drink. One robin sipped 38 times before leaving! Eventually eight species of birds and two mammals drank.
