How DOES a little chickadee survive a freezing night. Many don’t. Every year, many of our tiny birds don’t live to see spring.….
But there are simple things you can do to help them survive.
A chickadee weighs about as much as a couple of quarters, and it has almost no fat reserve to spare. To get through the night it fluffs its feathers to trap air, shivers to generate heat, and can lowers its body temperature to save energy, a controlled drop that biologists call regulated hypothermia. It also spends the night tucked into a cavity or dense shelter out of the wind.
All of that burns energy. By morning, a chickadee may have used up most of the fat it gained the day before, which is why the first hours of daylight are a race to eat. What actually kills them? Cold is rarely the direct cause. The danger comes when the energy doesn’t get replaced: snow or ice covers natural food, a cold snap lasts several days, or when every water source is frozen solid.
WATER that doesn’t freeze. matters more than most people realize. Birds need it to drink, and they need it to keep their feathers clean, because dirty, matted plumage traps far less warm air. The simplest, most effective help is a heated birdbath, or a shallow dish refilled with fresh water every morning on freezing days, gives birds something that becomes almost impossible to find in deep winter. Place it near shrubs or trees so they have cover, and keep it clean.
FOOD. If your landscape doesn’t contain the native trees and shrubs that normally would provide them with food, and your area gardens have been “cleaned up” (….meaning no one left the stems and dried seed heads of goldenrod, asters, coneflowers and other perennial natives standing over winter (so the seeds remain above the snow and reach or rodents), and if the fallen leaves that might hide grubs and hibernating insects have all been raked away..…..) well then feeders will really help. High-energy food like black-oil sunflower seed, suet and unsalted peanuts help chickadees rebuild their reserves each day. They will also benefit our titmice and nuthatches. What fun it is to watch them take turns at the feeder as if it were a cafeteria lunch counter.
SHELTER: leave nest boxes up over winter. Empty boxes become roosts on freezing nights, sometimes for several birds at once.
Start before the first hard frost if you can. Birds map out their winter food and water sources before the extreme cold arrives. A garden that offers them consistently now is one they’ll rely on in January. And if you still have a box to prepare, now is the time to clean out the nest box so it’s ready to serve as a winter roost.
A dish of fresh water every frosty morning sounds like nothing, but for a bird that weighs half an ounce, it can be everything!
