Sub Zero Temperatures Are For the Birds Unless You Are One
When temperatures get this cold, even the feathered ones need some help to survive. The Master Gardeners at Cornell Cooperative Extension have some tips on how to help them cope and add some beauty to your back yard too.
Keep Water Flowing
Yes it's nearly impossible when it's this cold. But use a shallow bowl and set it out at the same time each day. Even better once in the morning and again in the afternoon.
Cold Weather Food
Suet is the best food in winter, it provides extra calories and helps keep them warm. It can be purchased in stores or can be easily with lard, corn meal and peanut butter. Another option is smearing peanut butter on pine cones and rolling them in birdseed. The Farmer's Almanac has a recipe for making suet.
