Winter is when backyard birds have the hardest time finding water. Natural sources freeze, and birds still need to drink and keep their feathers clean to stay insulated. Seeing birds drink and bathe when it's below freezing is normal — what they can't use is a solid sheet of ice. A heated bird bath fixes that with a small sealed heater and a thermostat that keeps the water just above freezing.
The differences between models come down to a few things: whether the heater is sealed and thermostat-controlled, how big and deep the basin is (shallow suits small birds but empties faster), how securely it mounts, and how long the cord is. Almost every heated bath ships with a short cord, so plan on an outdoor-rated extension cord.

Where the bath goes decides which one to buy. A deck or railing mount puts water where you can see it from a window and refill it from the door — Birds & Blooms recommends exactly that for winter, since you're less likely to keep up with a bath you have to wade through snow to reach. A pedestal works anywhere in the yard but needs to be heavy or anchored so wind doesn't tip it. A ground stake is the cheapest way to get a bath into a garden bed, but a thin stake is also the part owners most often say bends or rusts.
Basin size is the other real choice. A 13-inch basin is easy to clean and refill and suits small songbirds, but owners of every small basin report frequent top-ups — a running heater speeds up evaporation, and cold air is dry. A 20-inch basin holds noticeably more water and room for several birds at once, at the cost of a bigger, heavier bowl to mount and dump.
The API 600 is a 20-inch, 2-inch-deep heated bowl from Allied Precision Industries (API). The wide bowl fits several birds at once and holds more water between refills than any 13-inch model, and its rim is shaped for birds to grip. It has a built-in thermostat and an adapter clamp for mounting to a post, rail or stand. Note that this listing is the bowl only — owners' most common complaint is the mounting hardware, so plan where it's going before you buy. Some owners also report it lasting about three winters.
If you want a freestanding bath that looks like a classic concrete one, the HBC-120C is a 120W heated bath on a molded pedestal about 29 inches tall, with a basin that lifts off for cleaning. It comes with a three-year limited warranty, and the extension cord plugs into a connection under the basin, which owners note keeps the plug up off the wet ground. Owners' complaints are consistent: the raised heater in the center makes it shallow, it can be top-heavy in wind unless you weight the base, and a few say birds were slow to use the light-colored basin.
The Daoeny is a 100W thermostatic heated basin on a 35-inch metal stake with a five-pronged base, the simplest way to put open water in a garden bed. The bowl lifts out of its ring for cleaning. It's a small basin, and the stake is the weak point: owners report the bowl sitting unevenly in its ring and, in some cases, the pole rusting or breaking within a season. Reasonable if you want a low-cost bath for a season or two; not the one to buy if you want it to last.
Open water brings more birds to your yard in winter than almost anything else. Pick the mount that fits your space.

Most "solar bird bath heaters" are solar fountains that keep water moving, which slows freezing in mild cold but stops working in deep cold, at night and on cloudy days — exactly when birds need water most. In a climate with regular hard freezes, a plug-in heated bath or deicer with a thermostat is the reliable option.
Yes. A thermostat-controlled heated bath keeps water just above freezing rather than making it warm, and birds drinking and bathing in winter is normal. What isn't safe is adding anything to the water to stop it freezing, or a heater that keeps warming water well past freezing. Check that the thermostat switches off once the water is ice-free.
Less than its wattage suggests. The heater only runs when the thermostat calls for it, so actual use depends on how cold it gets. At the absolute maximum, a 75W heater running nonstop for a full day uses 1.8 kWh; in practice it cycles on and off, so most days use a fraction of that.
Yes — a submersible bird bath deicer sits in the bottom of an existing bath. Choose one with a thermostat that turns off once the water is above freezing, and avoid using concrete, stone or glass baths in freezing weather, since they can crack if the water freezes. A dedicated heated bath is usually easier, because the heater is sealed into the basin and there's no cord running through the water.
Near an outdoor outlet so you need as little extension cord as possible, within sight of a window, and close enough to a door that refilling it in snow is easy. Put it near shrubs or trees birds can retreat to, but not directly under a feeder.
