Heated bird baths are life savers during wicked winter weather, and that has finally come our way. Have you set up one or two or three to provide birds with drinking and bathing water through snow storms and stretches where all natural water sources are frozen solid? If not, read on!
Wildlife needs are pretty basic: food, cover, and water.
FOOD needs can be met by planting (or preserving) native nectar plants and native berry-producing and seed-producing plants.
COVER is crucial so that birds and other wildlife can avoid becoming a predator’s next meal. Cover also provides safe places to nest, roost through the night, or get out of bad weather. Native evergreens like Red Cedar, American Holly, and Waxmyrtle offer excellent cover for wildlife. If your yard is wide open and without adequate cover, gather fallen branches and make a winter brush pile. You’ll be amazed by all the action it attracts as birds dash for the safety it offers when a hungry hawk flies through the yard. Or collect discarded Christmas trees and place them near bird feeding stations and bird baths, so that birds are not too vulnerable when they come to feed or drink or bathe. And next spring seriously consider planting a Red Cedar (or American Holly or Waxmyrtle) or two or three!
Providing WATER is just as important as providing food and cover
Songbirds lose water through respiration and in their droppings. To replace lost water, most songbirds need to drink at least twice a day. In order to stay fit and healthy birds also need to bathe to keep their feathers in good condition. Bathing loosens dirt and makes their feathers easier to preen. Preening is a daily ritual where birds carefully clean, rearrange, and oil their feathers (one-by-one) with their bill — spreading oil along each feather from the preen gland. This daily preening successfully waterproofs their feathers and traps an insulating layer of air underneath to keep them warm. Keeping their feathers in perfect condition through daily preening is a matter of life and death. Well maintained feathers enable birds to fly at a moment’s notice and regulate their body temperature.
Birds face difficult times when water is scarce or nonexistent during deep freezes like have experienced this week and will undoubtedly face again this winter or during drought periods.
Heated Bird Bath
Providing water in the wildlife garden is something many accomplish easily spring through fall, yet fail to do once freezing winter temperatures settle in. There are solutions even in the dead of winter. A heated bird bath coupled with an outdoor socket is the key. We use an outdoor power cord to connect the two.
We’ve had our Pole Mounted ERVA Heated Birdbath (photo above) for over 25 years. The pole with its additional leg for support, when driven into the ground, makes this birdbath very sturdy so it remains standing no matter 
what! In the summer months I use the same stand to hold a large plastic dish/tray (like you’d put under a large flower pot) full of gooey fruit for butterflies. So even though expensive, this heated birdbath has served me (and wildlife) very, very well. Beware that most of today’s standing heated bird bath designs are tipsy by comparison (bird baths balanced on inadequate tripod legs), looking like they’d topple over every time a frisky squirrel leaps up.
As of January 20, 2024, the Pole Mounted ERVA Heated Birdbath is available at 1st State Seed Garden Supply (best price, $15 less than other sites) and at Nature House, Best Nest, Amazon, Freeport Wild Bird Supply, Feed the Birds, Walmart, and probably elsewhere.
Some heated bird baths rest on the ground and come with additional hardware so they can be attached to a railing like this one (photo above). If far from cover, place some cut evergreen branches nearby, as we have.
Wildlife gardening friend Jean Riling uses a Bird Bath De-icer unit to keep her bird bath water from freezing (photo below). Ecosystem Gardener Carole Brown uses a heated dog bowl.
Garden Gang member Steve Mattan shared that he uses a special plug to control when his heated bird bath turns on and off (the plug / thermostatically controlled outlet powers ON at 32-Degrees and OFF at 50-Degrees ). How cool is that? Clay & I unplug our extension cord when it’s warm and plug it back in when temperatures drop, but this special plug can save the day if you’re not paying attention.
Shy away from “artistic” bird baths that may look pretty but are not as serviceable to birds: too deep, too fragile and likely to break if they topple over, or (most important of all) are too hard to keep clean. The heated bird baths we’ve used are made of a hard black plastic material that is very easy to clean with a good scrub brush and a little muscle.
If You Have a Wildlife Pond
If you have a wildlife pond and are thinking of putting a de-icer into it to make that your winter water source for birds, this could lead to some serious problems. If indeed large flocks of birds descend on your pond to drink, their droppings will accumulate in your pond and you could face an algae problem during the warm month fueled by all these bird droppings.
Remember, birds need cover to avoid hungry predators. Place your heated bird bath near a safe retreat like an evergreen tree or shrub or near a brush pile or, as we have, place some cut evergreen branches around it.
Stay away from chemicals!
Some folks, who don’t know better, add chemicals to keep their bird bath water from freezing (like glycerine, anti-freeze, or salt). This is a death sentence for the birds. These chemicals can destroy the waterproofing capability of birds’ feathers, or poison the birds.
During lengthy periods of frozen conditions water is in such demand that heated bird baths become heavily soiled. To avoid the spread of disease, maintain your heated bird bath with care by scrubbing it out with a soft bristle brush, rinse it with fresh water to wash out any residual bird droppings, and refill it with fresh water at least once (and often twice) a day. With heavy use heated bird baths may be emptied by flocks of birds twice a day or more. We keep a jug of water handy by the backdoor to easily facilitate this task.
Beyond helping birds survive brutal winter weather, our heated bird baths give us great pleasure. We’ve had excellent looks (and photo opportunities) at some real skulkers like Hermit Thrush, Gray Catbird, Brown Thrasher, and other secretive birds not normally seen in our yard in winter.
Winter can be a stressful time for birds. Lengthy stretches of sub-zero weather can freeze solid every last bit of available water. Natural foods can be buried by snow. Heavy snow or freezing rain can creep into the deepest cover where birds are roosting.
Let’s do what we can to help birds survive a tough winter. Add a heated bird bath or two to your wildlife habitat in winter.
