Actually JW, the temperature rose to a record high here Saturday. Friday I went to the field with a tee shirt, long sleeve heavy shirt and a jacket, Saturday, I wore a tee shirt with my Bug Tamer jacket and was sweating when I got to the spot. I wonder if the temperature makes a dramatic change from cooler to warmer if that would slow the birds down as well. We rode around and can usually see a few birds in the roads and the fields but we only saw a lone hen run from a field. Any ideas? Should I try this spot again in the morning or wait until it cools off later in the week?
