A wildlife expert is recommending a lesser-known hack to help purify and clean the water of a bird bath – all you need is this copper disc from Amazon.
Adding copper or even a penny to your bird bath is an excellent and natural way to prevent the growth of harmful algae, keeping the birds that visit your garden safe and happy to cool off in your bird bath.
If you want to attract birds to your garden this summer, it’s important to provide a safe environment for them to thrive. Cleaning your bird bath (and then keeping it clean) is one of the most important things you can do. Here’s how adding a copper disc can help you keep on top of this vital maintenance task.

Why you should add a copper disc to your bird bath
neglecting to change the water often enough or not cleaning it properly are two of the biggest bird bath mistakes you can make.
Harmful algae can build up in your bath, and can sometimes be fatal for birds. A copper disc can help naturally purify the water, preventing a build-up of algae.
‘Copper is a natural algicide and can improve water clarity – inhibiting growth of algae along with other microorganisms. Some algae can actually be beneficial to birds, providing them with a welcome food source, but blue-green algae (cyanobacteria) can pose a great risk to our feathered friends – releasing toxins that can be fatal, explains James Ewens, wildlife expert from Green Feathers.
‘Copper can help prevent the growth of harmful algae, creating a cleaner and healthier environment for birds and animals, and prevent diseases from bacteria and pathogens.
‘Not only does copper have these antimicrobial effects, but it also has a welcome bonus of being appealing to birds in that they’re drawn in by the shine! Copper sparkles in the sun, which can attract birds like magpies and crows to your garden.’
Copper discs vs copper bird baths
Equally, you can also invest in a copper bird bath. Not only do you get the benefits of copper, but they look stunning, too. I personally love the finish of copper bird baths. For example, this fired copper bird bath (£111.56 on Amazon) has a unique finish that is perfect for catching the sunlight of your garden.
However, James says that discs actually work as well as copper baths, so you don’t have to upgrade your bird bath if you don’t need to.
‘For most households, a copper disc is much more feasible! A disc can be added to an existing bird bath, making it a cheap, simple, smart upgrade rather than buying a whole new bird bath. You still reap the benefits of the copper, just in a smaller dose, but it’s far cheaper to add a copper disc, and I dare say equally effective,’ he says.
Vital bird bath maintenance
While it’s definitely a good idea to add a copper disc to your birdbath, making your wildlife garden a slightly more welcoming place in the process, it’s still important to carry out bird bath maintenance. In other words, just because the disc reduces algae, it doesn’t mean you can stop cleaning it altogether.
‘Regular maintenance is essential! Copper in a bird bath should be treated as a welcomed addition to the usual crucial maintenance – like cleaning the bird bath regularly, and keeping water constantly replenished for our feathered friends,’ says James.
‘Fresh water should be refreshed every couple of days, especially in hot weather and in times of increased use like breeding and nesting season. Copper helps slow biological growth, but it does not prevent the build-up of dirt, droppings, feathers, or biofilm entirely.
‘A classic brush and clean water without harsh chemicals is ideal for cleaning, keeping the bath in partial or full shade, and refreshing the water frequently are the most important factors for birds.’
If you want to keep your garden birds happy, this is one affordable, effective change you can make.
