Winter is a great time to watch birds and see species that we don't otherwise get to see. I've had several irruptive species at my feeders lately. Pine Siskins and Purple Finches are known as irruptive species because they only periodically migrate south when the food they need is unavailable in northern climates.
We had a dusting of snow last Friday with temperatures 34 F degrees. There is something welcoming about snow that pulls me outside to watch birds when the temperature is tolerable. They seem to be less shy and come closer.
