Looking out my window and watching the finches, chick-a-dees, juncos, cardinals, assorted sparrows and a plethora of woodpeckers cramming around my feeders, I can generally tell how cold the temperatures are outside. If the feeders are overflowing with a waiting gallery in the nearby trees, I know that it is very cold and most likely below 30 degrees; if the feeders have constant traffic, but not overcrowding, then I know it is mildly cold. This always makes me think about the number of people who enjoy bird feeding and bird watching.
