How do birds survive winter?
Look it up on Youtube . Fascinating stuff. Like, small birds, like finches, have the ability to reduce the core temperature of their feet to just above zero. The rest of their body does that to a degree but not as well. These little birds fluff up feathers to twice the size they are in summer. They have learned to bunch up with three or four other birds for added body warmth at night. Food isn't easy to find in winter. These little creatures when finding a food source stick a little extra stored in their craw to nibble on and make it through the night.
Larger birds, with their greater mass, are able to distribute and maintain heat in their bodies more efficiently than small birds. One thing I noticed personally today is how eagles (a Youtube cam showing a nesting one) and seagulls both turn their heads around and snuggle their beaks back between their closed wings to add a little extra warmth while resting in cold weather.
Many birds know it is just better to get the !$#% out of a bad situation. They migrate before winter and come back when the weather is good.
Today, I finished making a nearly free DIY bird feeder out of two pop bottles, glue and a plate to help birds survive the winter. Small birds prefer this hanging while large birds use it when the bird feeder is placed on the ground. To attract both kinds of birds to your yard, make two, that is just the way birds work.
