How do you get rid of algae in a bird bath? Give it a proper clean! Soaking the bird bath in vinegar will help to kill any algae that may have found its way in.

Keeping a bird bath clean is a task all by itself but it becomes even more difficult when there is algae present. Although the algae won’t harm the birds, it makes the water unattractive to them and so they won’t visit your garden.

If you want to continue enjoying feathered visitors at your bird bath, make sure that the water stays clean. Here is all you need to know about algae in bird baths and how to get rid of it.

What Causes Algae in a Bird Bath

Algae is rootless plant that often grows in damp conditions, like a bird bath. Once it establishes itself, it quickly reproduces – in other words, algae can spread quickly in a bird bath under the right conditions.

It travels as spores in the air or carried on the bodies of insects and birds from other locations where it is already established. Examples of sources are plants or a nearby pond or river.

Algae, like all plants, reproduces by photosynthesis – the sun’s energy. How fast the algae colony spreads depends on the nutrients available in the water and in the air, specifically oxygen, phosphorus and nitrogen.

When a colony spreads in your bird bath, it removes all the natural nutrients in the water. This is sometimes referred to as choking the water.

Birds like clear fresh water, the opposite of a bird bath contaminated with algae. So, the birds don’t leave because the algae is dangerous but they avoid it because it is unpleasant to them.

Algae is not always a bad thing, there are also algae variations that serve as a vital link in a food chain. However, the algae that grows in a bird bath does not fall under this category.

Red Algae

Red algae, also known as Haematococcus pluvialis, is the most common type of algae occurring in bird baths. It gives the water and the sides of the bird bath an slimy red tinge.

This type does especially well in full sunlight and hot weather which is why some recommend moving it to a more shady spot. Keep in mind however that this shady spot should not be directly under any trees because algae spores could fall down into the bird bath.
