Add 1 part rubbing alcohol to 4 parts water. The birds probably will be switching to snow or dirt baths during winter anyway, but if your birdbath has a pump, this mixture will prevent the water from freezing. This method also works in the windshield wiper fluid reservoir on a car.
take the water out
Yes, but the algae that turns the water green or red does not hurt birds. If you don't like the way it looks, try a little barley straw or barley extract in the water.

If water contracted on freezing, it would have catastrophic implications for aquatic life. Instead of the ice staying on top at the surface of the water, it would sink if it contracted. This would kill aquatic life.
Discoloring the water in your birdbath -- Haematococcus is a type of reddish or pinkish fresh water algae.Haematococcus, common polluter of birdbaths, probably does annoy at least some of the wildlife. Then again, probably not all that much. About semi-immortal and seemingly harmless chameleon-like algae, which is a fair to middling introductory description of Haematococcus pluvalis, birdbath division. Maybe it will eat fungus. Or absorb it, or something. Haematococcus pluvalis resembles an organic rust. When one scrapes it, dry and seemingly dead from the birdbath's bottom, it has yet some life left to it. It is in a state resembling dormancy. If one is so inclined, one can reach into one's home laboratory, grab a cover slip, put a sample of Haematococcus beneath it and add a bit of moisture. Through the microscope glass, one can then watch excitedly as Haematococcus perks right up.(see the related image link)
The only night crawler to live in salt water is the European Night Crawler. It is suitable for bait in brackish salt water. They can live up to 30 minutes in freezing or salty water.
Putting your birdbath in a place that is shaded will slow the evaporation of the water.
SALT

Birds are attracted to moving water with its shimmering, shining properties. As long as the water in a birdbath or other man-made feature is moving, the chance it will attract birds is very good, whatever the color scheme of the birdbath may be.
7 table spoons of salt stops 500ml of water from freezing
heat it up, add energy to it
I think that you just let the rain or birdbath water water the grass around it and it will start turning green 😊🌾
The freezing cannot be stopped; only the freezing temperature is lowered adding salts.
A birdbath is typically a shallow bowl filled with water that is either on the ground or on a pedestal. Birds will use the water to drink or take a bath. You can purchase a bird bath at your local garden store.
In the winter, when the temps go below freezing, there should not be any water in a car. It should be antifreeze, actual windshield wiper fluid, etc.... This will prevent any freezing.
Turn your freezer off before putting the water inside.
Believe it or not, you can keep water protected in Antarctica by keeping it in a fridge. The temperature is so cold that a fridge could keep it safe from freezing.
