The 5 Best Heated Bird Baths for Winter (2026)

The 5 Best Heated Bird Baths for Winter (2026)

As an Amazon Associate we earn from qualifying purchases. Some brands also pay us when you click or buy, so those links are ads. Full disclosure below

The best heated bird bath for most yards is the Farm Innovators HBC-120C: a 120 watt heated bowl that Farm Innovators says heats only when needed, on its own matching pedestal, so you need no deck rail and can set it wherever an outdoor outlet reaches. If you love the bath you have and it sits within reach of an outdoor outlet, a thermostatic bird bath de-icer keeps it open instead. Whichever you choose, it runs all winter on an outdoor outlet, so how you plug it in matters as much as which one you buy.

We make digging spades, not bird baths, so nothing here is ours. Each pick is judged on what its heater and thermostat actually are according to its listing and its maker, how it mounts, what its maker says about cords and outlets, and what the people who recommend it found.

1. Farm Innovators HBC-120C: best overall

Best overall

Best for: Most yards, no deck needed

Farm Innovators HBC-120C

  • Type and mount: Scalloped bowl on a pedestal
  • Heater: 120 W (maker)
  • Thermostat: Yes (maker)

A 120 watt heated bowl on its matching pedestal, in a scalloped design made to resemble a concrete bath, though we found no cold-weather figure for this model from Farm Innovators.

Check price on Amazon

This is the one to buy for most yards: a heated bath on its own pedestal, so it needs no deck rail, and in a garden bed it looks the part. It pairs Farm Innovators' 120 watt heated bowl (HBC-120) with its matching pedestal, and the listing describes a scalloped, compression-molded design made to resemble a concrete bath. Birds and Blooms chose this listing as its heated pedestal bath and thought it looked sturdy enough to stay up in a blizzard. Farm Innovators says it is thermostatically controlled and only heats when needed. The connection is hidden: per the instructions, you feed a fully grounded outdoor extension cord up through the opening in the bottom of the pedestal and plug it into a socket under the bowl, then twist the bowl onto the pedestal threads.

The listing puts it at 18 by 18 by 29 inches and 16 pounds, and the bowl lifts off the pedestal for cleaning, a point Bird Watching HQ also makes.

Where it loses: fine print and cold. The listing says three-year warranty, but the printed instructions limit those three years to the heated top basin. We found no cold-weather rating for this model from Farm Innovators. The instructions say never to immerse it and to unplug it whenever it is not in use.

2. API Heated Bird Bath with Stand (970): 20 inch bath on a metal stand

20 inch bath on a metal stand

Best for: A yard with no deck rail to clamp to

API 970 Heated Bird Bath with Stand

  • Type and mount: Bowl on a 30 in metal stand
  • Heater: 150 W (Miller)
  • Thermostat: Keeps the water at 40 to 50 F (listing)

API's 20 inch, 150 watt heated bowl with a built-in thermostat on its own 30 inch metal stand, a working bath rather than a garden ornament.

Check price on Amazon

This is API's 20 inch heated bath sold with a 30 inch metal stand, for a yard with no deck rail to clamp to. Birds and Blooms picked this exact listing for that reason, and adds that a bath on a stand is easy to move nearer the front door, so refilling it does not mean wading through drifts. Miller Manufacturing, which makes API baths, rates the heater at 150 watts on 120 volts and says the bath is CSA listed. The listing says the heating element is fully enclosed so animals cannot touch it, that a built-in thermostat holds the water between 40 and 50 degrees F, that the stand resists rust and corrosion, and that the rim is shaped for a bird's feet to grip. API's own comparison chart on the listing gives the bowl a 2 inch depth and says it can also go on a deck rail.

Bob Vila's testers ran the deck-mount version of this 20 inch API bath (the 650, under Also considered) and say the water they put in it never froze during their test. Bird Watching HQ lists this stand model too, and The Spruce names API's 20 inch heated deck-mount bath its best heated option.

Where it loses: looks and the cord. Bird Watching HQ calls the stand a basic design, so this is a working bath rather than a garden ornament; pick 1 is the one that looks like a classic pedestal. Its Amazon description gives it a 15 inch power cord, and Bob Vila's testers found the cord on the deck-mount sibling a bit short and added an outdoor-rated extension cord, so read the cord section below before you set it up. The listing is inconsistent on the warranty: its details say one year against defects, while its description says three years.

3. API Heated Bird Bath (600): for a deck rail or the pedestal you have

For a deck rail or the pedestal you have

Best for: Wooden or metal deck rails, pedestal tops and metal feeder poles

API 600 Heated Bird Bath

  • Type and mount: Bowl with a universal clamp
  • Heater: 150 W (manual)
  • Thermostat: Cycles the water between 40 and 50 F (manual)

The same 20 inch, 150 watt bowl with a clamp in place of a stand, though you supply the rail, pole or pedestal, and fitting the clamp takes a screwdriver and an adjustable wrench.

Check price on Amazon

API's 20 inch, 150 watt heated bath sold as the bowl alone, with a clamp in place of a stand. API's printed instructions spell out where the clamp goes: it fits wooden deck railings from narrow to 12 inches wide, metal railings, pedestal tops (with separate steps for tops up to 7.25 inches and for 7.25 to 8.25 inches), and metal feeder poles, and the bath can also sit on any flat surface. Once the clamp is on, you spin the bath on and off it to clean, and API suggests swapping your usual bath back onto the pedestal after winter to extend the heated one's life. The listing gives its dimensions as 20 by 20 by 2 inches.

The manual also says how the thermostat behaves: the heater does not run all the time, because the thermostat cycles the water between 40 and 50 degrees F. Bob Vila's test of the deck-mount 650 is the closest hands-on evidence for this bath.

Where it loses: setup. You supply the rail, pole or pedestal, and fitting the clamp takes a screwdriver and an adjustable wrench; the manual also says the clamp will not grip a pedestal with a screw sticking out of its top unless that screw comes out. The manual asks for a grounded outlet and an outdoor-rated cord, and says not to set the bath directly on the ground. It has no tilt bracket for dumping old water; that is what the 650 adds.

4. Farm Innovators 3-in-1 (BD-75): for small spaces

For small spaces

Best for: A balcony, a narrow deck or a small yard

Farm Innovators 3-in-1 (BD-75)

  • Type and mount: Bowl with three mounts
  • Heater: 75 W (listing)
  • Thermostat: Yes (maker)

A 75 watt heated bowl with three ways to mount it, tested at -10 degrees F by Farm Innovators, though it is about 14 inches across against 20 inches for picks 2 and 3.

Check price on Amazon

A 75 watt heated bowl, about 14 inches across, that comes with three ways to mount it, which makes it the flexible pick for a balcony, a narrow deck or a small yard. Per Farm Innovators' instructions, one bracket screws to a 2x4 or 2x6 railing or a 4x4 post, a second clamps to the top or bottom rail of a deck, and a set of legs puts it on the ground or another solid surface. Farm Innovators says it is thermostatically controlled and was tested at -10 degrees F, and that the cord tucks out of sight so the bath can stay out all year. Bird Watching HQ lists it and found it light, durable and very easy to clean; its tip is to drop a few stones in the bowl to give birds more than one depth.

Where it loses: size. The bowl is about 14 inches across, against 20 inches for picks 2 and 3. Its listing's bullets give no cold rating, so the -10 F figure here is Farm Innovators' own. The instructions give a one-year warranty and ask for a fully grounded outdoor extension cord.

5. Farm Innovators Four Seasons (FS-1): ground-level bath

Ground-level bath

Best for: Ground-level drinking where cats are not regular visitors

Farm Innovators Four Seasons (FS-1)

  • Type and mount: Sand-coated ground bath
  • Heater: 70 W (listing)
  • Thermostat: On below 35 F (manual)

A 70 watt sand-coated bath that sits on the ground, though Bird Watching HQ found the coating starts peeling and cracking after a season or two.

Check price on Amazon

A 70 watt heated bath that sits on the ground, with a sand-coated, rock-style finish meant to look like a small stone pond. It suits a yard where you want birds, and the deer and squirrels that will share it, drinking at ground level, and where cats are not regular visitors. Bird Watching HQ's founder has gone through a few in his own yard and makes the case for ground baths: birds drink and bathe at ground level in nature, a ground bath is easy to clean and move, and it also waters deer, squirrels and raccoons (he has filmed a hawk drinking from his). Its rough surface, he notes, keeps landing birds from slipping. Farm Innovators' instructions say the thermostat switches the heater on only when temperatures drop below 35 F, recommend it for use down to 0 F, and say to set it on a hard, flat surface and keep it out of the wind.

Where it loses: durability and cats. Bird Watching HQ found the coating starts peeling and cracking after a season or two, which is why he has replaced his more than once. A ground bath also gives up height: Audubon says pedestal baths are best for cutting the risk from predators such as cats. The instructions call for a "heavy duty fully grounded extension cord" and for unplugging it in warm weather, and give a one-year warranty.

How we chose

The one hands-on test of a heated bath we found is in Bob Vila's bird bath roundup, whose testers ran API's 20 inch deck-mount 650 and report that its water never froze. The Spruce names Allied Precision's 20 inch heated deck-mount bath, API's deck-mount model, its best heated option (we could read only its search snippet). Picks 2 and 3 are API's 20 inch, 150 watt heated bath on a stand and on a universal clamp; the 650 itself is under Also considered. We also read the heated picks from Birds and Blooms and from Bird Watching HQ, whose founder writes from his own yard, then checked every pick against its Amazon listing and its maker's page or printed instructions: Miller Manufacturing (API's maker) for picks 2 and 3, Farm Innovators for picks 1, 4 and 5, and K&H for its de-icers.

Our rules: a full pick needed a thermostat its listing or maker states, and a maker page or manual we could read. We re-checked every pick on Amazon on October 23, 2026 and moved the Farm Innovators HBC-120C to pick 1; that day it was in stock as new. Pick 4's link changed on October 25, 2026: the Farm Innovators 3-in-1 listing we had linked was not available new on Amazon that day, so the link now goes to another Amazon listing of the same Farm Innovators bath in green, which was in stock as new when we checked. Every wattage, thermostat and cold rating here comes from those listings and maker documents, and where the two disagree we say so. Electrical safety comes only from the makers, the US Consumer Product Safety Commission (CPSC), NFPA, the National Wildlife Federation and All About Birds, named where they appear. Placement and winter care come from Audubon, Bob Vila and the Wild Birds Unlimited expert it quotes, All About Birds, the National Wildlife Federation and UNH Extension.

Also considered: models that missed the list and why

API 650 Heated Deck-Mount Bird Bath. The one heated bath with a hands-on test behind it: Bob Vila's testers kept water open in it through their test, and The Spruce names API's 20 inch heated deck-mount bath its best heated option. It is API's 20 inch, 150 watt bath with an EZ-Tilt bracket for a 2x4 or 2x6 deck rail that lets the bath lift and tip so you can dump old water. It sits a step behind pick 3 because Miller sells its tilt bracket for a 2x4 or 2x6 wooden deck rail, while pick 3's clamp also fits wider rails, metal rails, pedestal tops and feeder poles. If you want to tip old water out without unclamping the bowl, and your bath will go on a 2x4 or 2x6 deck rail, this is the one to buy: its Amazon description says the thermostat is built in and rates it to -20 F, and it is the bath Bob Vila's testers used. It was not in stock on Amazon on October 13, 2026, so we did not link it.

API 14B Four Seasons Heated Bird Bath. A 14 inch, 70 watt API bath whose kit includes an EZ-Tilt deck mount plus a pole that stakes into the ground, and a three-year warranty in its printed instructions. It missed because its paperwork disagrees with itself: the instructions say it "is thermostatically controlled and will not be damaged if the bath runs out of water," and its Amazon description also says thermostatically controlled and tested to -20 F, yet one of the listing's bullets says "No Thermostat." Pick 4 covers the same small-bath job with a maker-stated thermostat.

GESAIL 75 W Heated Bird Bath. The same idea as pick 4: an enclosed 75 watt heater, a thermostat, and deck, clamp and ground mounts, with a bowl that lifts off for cleaning. It missed because its listing gives no cold rating, while Farm Innovators publishes a -10 F test for pick 4.

K&H Ice Eliminator de-icer (50 W). The de-icer to look at first for a plastic or metal bath you want to keep. It is not a bath at all: a 50 watt, rock-shaped heater that sits on the floor of the bath you already own and keeps the water open. K&H says it is thermostatically controlled, switching itself on and off as needed, MET listed, covered by a three-year warranty, and that it will not melt plastic baths or leave rust stains. Bird Watching HQ puts this exact listing first and makes the point that a de-icer turns any bath into a heated one and goes back in storage come spring. K&H sizes its two de-icers by how much water the bath holds: this 50 watt Original for 10 gallons or less, and the 80 watt Super Ice Eliminator, which Birds and Blooms chose, for larger ones. The Super's listing pitches it at larger birdbaths and claims open water down to -20 degrees F. With either, mind the cord and the water level. K&H's FAQ says the cord is 18 inches long and that its MET listing requires a "Do not use with extension cord" statement on the unit, so it suits a bath within reach of an outdoor outlet; K&H's printed manual, by contrast, says to "plug it into a grounded extension cord," so follow the label on the unit you receive. It has to stay fully under water: K&H says to unplug it if the bath will run dry regularly, and to unplug it before cleaning. The Original missed the numbered list on stock alone: Amazon showed it only in limited stock on October 13, 2026, and it was not in stock on Amazon on October 23, 2026, so we did not link it.

GESAIL 50 W Bird Bath De-Icer. A cast aluminum de-icer with a thermostat and a 25 inch cord, which its listing says can go in metal, plastic, stone or glass baths. It missed because its listing names no safety certification, where K&H names MET for both of its Ice Eliminators.

Water movers. When it is not too cold, Birds and Blooms says moving water alone can keep a bath from freezing, and suggests a Water Wiggler agitator or a small fountain. It is a mild-weather fix, not a substitute for a heater in a hard freeze, so none is on the list.

Every model compared: watts, amps and energy per day

Three columns are computed from each maker's or listing's wattage at 120 volts, which API, Farm Innovators and GESAIL list (K&H states no voltage): the current the heater draws, the most energy it could use in a day if its thermostat never switched it off, and how much of a 16 gauge extension cord's capacity it takes, using CPSC's figure that a 16 gauge cord handles 1,375 watts. A thermostat cycles the heater, so real use is lower than the daily figure, and it depends on how cold it gets. The takeaway: every heater here draws between 0.42 and 1.25 amps, a small fraction of the 1,375 watts CPSC gives for a 16 gauge cord. The cord rules the makers and CPSC do set, below, are about outdoor rating, grounding and keeping the connection dry.

How to plug in a heated bird bath safely

A heated bath runs on an outdoor outlet all winter, so here is what its makers and the public safety agencies ask for, each named. It is not wiring advice: if your outdoor outlet needs work, that is a job for an electrician.

  • A GFCI-protected outlet. All About Birds, the Cornell Lab's site, puts it plainly: "Plug your heater into a ground-fault interrupted circuit to eliminate the chance of electric shock." The National Wildlife Federation gives the same advice. CPSC's home electrical safety checklist, on outdoor outlets: "Have GFCIs installed or plug in a portable GFCI when you use an outdoor outlet."
  • A cover that works with the plug in. CPSC notes that most outlet covers do not keep water out while a cord is plugged in, and says an outlet that must be used in wet weather should get a "weatherproof while in use" cover. The National Wildlife Federation adds: keep cords and outlets sheltered from snow and ice.
  • Grounded, and a cord rated for outdoor use. API's manual for pick 3 says to use grounded outlets only, to ask an electrician if you doubt your outdoor outlet's ground, and to use only an outdoor-rated extension cord that can carry more than 150 watts. Farm Innovators' instructions for picks 1, 4 and 5 each call for a fully grounded extension cord, outdoor or heavy duty. CPSC says to use cords marked for outdoor use and three-prong cords with the grounded plugs on outdoor products.
  • Keep the connection out of snow and water. API's manual says not to let the cord connection lie in snow or water, and to keep the bath away from snow drifts and from spots where water pools.
  • Not every heater takes an extension cord. K&H, maker of the Ice Eliminator de-icers, says its MET listing requires a "Do not use with extension cord" statement and that its cord is 18 inches long, so plan on an outlet beside the bath.
  • Extension cords are not permanent wiring. CPSC says "extension cords are not as safe as permanent house wiring" and that, where a cord is in use permanently, you should have new outlets installed where they are needed or move the appliance closer to an outlet. The NFPA's fire code, quoted on the NFPA's own blog, says an extension cord should serve only one portable appliance and should not be fastened to structures or left exposed to environmental or physical damage. K&H's FAQ adds that MET does not recommend an extension cord as a permanent fixture, only as a temporary solution.

The same outdoor cord and outlet questions come up for anything heated that sits in winter water; our guide to the best heated chicken waterer covers what those makers require for a coop.

Where to put a heated bird bath

The short version: put it where a cord from an outdoor outlet reaches, in sight of shrubs but not right against them, 10 to 15 feet from your feeders and, if cats visit, up on a pedestal or rail rather than on the ground. In winter, a sunny spot helps.

The sources split on shrubs. Audubon wants water near protective shrubs; Wild Birds Unlimited's Cunningham wants the bath 10 to 15 feet from them, so a predator cannot sneak up from cover, while cover stays close enough for birds to duck into after bathing. Read together: cover in sight, not cover you could reach out and touch. On sun, the National Wildlife Federation's winter advice is a sunny spot; Bob Vila's case for shade is strong midday sun overheating the water, and Cunningham's is algae, both warm-weather problems. For a deck-rail bath near the house, the window point is the one to watch: Bob Vila suggests decals if the bath sits near glass.

If you also feed birds, keep the bath 10 to 15 feet from the feeders, as Bob Vila advises, so droppings and debris stay out of the water. Our guide to the best squirrel-proof bird feeder covers where to hang the feeder itself.

Here is what each source says.

Source Cover and shrubs Height and footing Feeders and windows Winter notes
Audubon Water near protective shrubs Pedestal baths best for cutting the risk from cats Not given Skip ceramic baths, which can crack; skip baths entirely if cats are a regular threat
Wild Birds Unlimited (Brian Cunningham, quoted by Bob Vila) 10 to 15 ft from shrubs, out of a predator's ambush range, with cover still in reach Not given Not given Shade, to discourage algae (not winter advice)
Bob Vila (the article quoting Cunningham) Not beside a fence or thick shrub High enough to be safe from ground predators 10 to 15 ft from feeders; away from windows, or add decals Shade, since strong midday sun can overheat the water
National Wildlife Federation Not given Not given Not given A sunny spot, where birds see the bath and the water stays liquid longer; stones or sticks as perches
All About Birds (Cornell Lab) Not given A shallow bath with a gentle slope Not given Stones or branches to stand on, especially in freezing weather
API manual (pick 3) Not given Not directly on the ground Not given Away from snow drifts and pooling water
Farm Innovators manual (pick 5) Not given Hard, flat surface Not given Protect it from wind
UNH Extension Not given Not given House cats and window strikes are risks at feeding stations Unfrozen water is especially hard for birds to find in winter

Do birds need heated bird baths in winter?

Not strictly, but it helps them, and it helps you see more of them. All About Birds says an ice-free bath in winter is not critical, because birds conserve water well and can usually make do with snow or icicle drip. The National Wildlife Federation adds the cost: melting frozen water takes calories and body heat birds can ill afford, and yards with liquid water in winter tend to draw more birds. Kenn and Kimberly Kaufman, quoted by Birds and Blooms, say that open water is harder for birds to find than food unless snow cover is heavy, that they keep a simple heater in their own bath all winter, and that birds drinking and even bathing below freezing "shouldn't cause alarm." UNH Extension says much the same: unfrozen water is especially hard to come by in winter, and a clean bath with an immersion heater answers it.

Heated bird bath or bird bath de-icer: which do you need?

A heated bird bath has the heater built into the bowl; a bird bath de-icer, also sold as a bird bath heater, is a separate thermostatic heater that sits in a bath you already own. Which you need comes down to the bath you have. Audubon's advice is a plastic bath with a heater built in, or a summer bath converted by adding a heater, and it says to avoid ceramic, which can crack in the cold; Birds and Blooms adds concrete, stone and glass to the list of baths that can crack if their water freezes, and the National Wildlife Federation says to store or cover concrete baths for winter. So:

  • No bath yet, or a ceramic or concrete one: a heated bath, picks 1 to 5.
  • A pedestal bath you like, with a top 8.25 inches across or less: pick 3's clamp sits on it for winter, and API suggests putting your regular bowl back in spring.
  • A plastic or metal bath you want to keep using: a de-icer; the ones we looked at, K&H's two Ice Eliminators and a GESAIL, are under Also considered. K&H says its de-icers will not melt plastic baths; use the 50 watt Original up to 10 gallons and the 80 watt Super above that. Check the distance first: K&H's cord is 18 inches and its MET label says not to use an extension cord, so a de-icer suits a bath beside an outdoor outlet; for a bath out in the yard, a heated bath on an outdoor-rated cord (picks 1 to 5) is what those makers allow.

One more check when you shop: read the listing for a wattage and a thermostat. A heated-bath link in one magazine roundup we read now opens an 11.5 inch metal bowl with no heater at all.

Winter care: refilling, cleaning and a first-frost test

  • Expect to top it up daily. API's manual explains that a well-shaped bath has a big surface for the water it holds, and that warm water in dry winter air evaporates fast, so adding water every day is normal.
  • Clear the rim. The Kaufmans brush the snow off the edges of their heated bath so birds such as cardinals can reach the water.
  • Give them somewhere to stand. All About Birds suggests setting stones or branches in the water as footholds, so birds can drink without wetting their feathers, and calls that especially important in freezing weather.
  • Clean without soaking the heater. API says to scrub the dish without putting the lower section under water; Farm Innovators says never to immerse its baths and suggests warm water or undiluted white vinegar for stubborn build-up; K&H says to unplug its de-icer before cleaning. Wild Birds Unlimited's Cunningham sanitizes with a 10 percent bleach solution and a stiff brush, then rinses, dries and refills.
  • Test it before the first freeze. Farm Innovators' instructions for pick 5 and K&H's FAQ both describe a freezer test: chill the unplugged heater, then plug it in and feel for warmth within minutes. Both tests are done with the unit out of the water.
  • Spring. Farm Innovators says to unplug in warm weather, and the cords on picks 4 and 5 tuck away for summer; API suggests swapping pick 3 back for your regular bowl.

A word from the people who wrote this

We are Spear Head Spade, and we make a double patented digging spade, not bird baths. The one digging job here is the cover birds need nearby: if your bath needs shrubs planted within dashing distance, set them the 10 to 15 feet off that Wild Birds Unlimited suggests, and our spade finder matches a spade to your soil.

Frequently asked questions

What is the best heated bird bath?

For most yards, the Farm Innovators HBC-120C: a 120 watt heated bowl that Farm Innovators says heats only when needed, on its own matching pedestal, so it needs no deck. To keep your own bath open where an outdoor outlet is close by, a thermostatic de-icer, covered under Also considered.

Does a heated bird bath need a GFCI outlet?

Plug it into one. All About Birds says: "Plug your heater into a ground-fault interrupted circuit to eliminate the chance of electric shock." CPSC says outdoor outlets should have GFCIs installed, or that you should use a portable GFCI with an outdoor outlet. API's manual also says to use grounded outlets only.

Can you use an extension cord with a heated bird bath?

For most baths here, yes, if it is the right cord: API asks for one rated for outdoor use and for more than 150 watts, Farm Innovators for a fully grounded outdoor or heavy-duty cord, and CPSC for cords marked for outdoor use. K&H's de-icer is the exception; its MET listing requires a "Do not use with extension cord" statement. CPSC also says extension cords are not a substitute for a permanent outlet.

How much electricity does a heated bird bath use?

The heaters here are rated from 50 to 150 watts. A 150 watt heater that never switched off would use 3.6 kWh in a day, but every pick has a thermostat that cycles it, so real use is lower and depends on the weather. API's manual says its thermostat keeps the water between 40 and 50 degrees F.

Can I add anything to keep a bird bath from freezing?

No. All About Birds says never to add antifreeze, which is poisonous to birds and other animals, and not to use glycerin, which can mat feathers and leave a bird open to hypothermia. The National Wildlife Federation warns that glycerin can also raise a bird's blood sugar, and Birds and Blooms says no additive is safe for birds.

How do you keep a bird bath from freezing without electricity?

Swap it rather than heat it. All About Birds suggests putting out a plastic bowl of water at a set time every day and taking it in once ice forms. The National Wildlife Federation suggests a few heavy-duty plant saucers that ice will not crack, replaced with fresh water each morning. Birds and Blooms suggests a bath near a window, refilled several times a day with water that is warm, not hot.

What happens if a heated bird bath runs dry?

Check your model. All About Birds says "Most new models turn off if the water in the bath dries up," but K&H says its de-icer is designed to stay submerged and should be unplugged if the bath will run dry regularly. Evaporation is the thing to watch: API's manual says to expect to add water every day in dry winter weather.

Is it safe for birds to bathe in winter?

The Kaufmans, quoted by Birds and Blooms, have seen birds drink and even bathe below freezing and say it "shouldn't cause alarm." The National Wildlife Federation says birds are unlikely to submerge in very cold weather, and suggests stones or sticks in the bath so they can stay dry while they drink.
