We had a snow day the other day. My husband decided to work from home. He was looking out our window at the bird feeder early in the morning and saw a bluebird on our feeder. It was the first time we have ever seen bluebirds in our yard. All day long there were four males and one female. The goldfinches were attempting to get some seed, but the bluebirds just hung out on the perches. Could it be a sign of spring?
