I Saw TikTok Telling People To Put Herbs In Their Bird Baths... But Is It Actually A Good Idea?

If there’s one thing many of us want more of in our gardens, it’s birds. And with summer heat making access to fresh water particularly important, bird baths have become a popular way to give our feathered visitors somewhere to drink, cool off and bathe... and marinade, apparently.

Yes, a new TikTok trend is encouraging people to add herbs and leaves to their bird baths, with the idea that the extra greenery and texture provided by all of those fragrant herbs will make the water all that more enticing to visiting birds.

On paper, it sounds like a dreamy idea: floating leaves add movement and visual interest to an otherwise rather boring bowl of water, and some people think that all of the rosemary and mint and the like will make the bird bath feel more natural, not to mention give birds something to peck and explore. But does it really work?

Should You Add Herbs To Your Bird Bath?

Look, I wanted to believe that adding herbs to my bird bath would prove a wonderful little treat for all my feathered pals, because I love birds. I know my birth month bird, I’ve spent far too much time researching what the birds I see most often in my garden supposedly say about me, I know exactly what the first bird I see each morning means for the day ahead, and I spend a frankly obscene amount of money on suet.

Basically, I am that person who leaves seed heads standing rather than cutting them back because I know the birds will make use of them. So, yes, when I started seeing herbs floating around in bird baths on TikTok, my first thought was that it looked a brilliant idea. Still, I couldn’t shake the feeling that putting anything other than clean water into a bird bath might be doing more harm than good.

So I asked someone who knows considerably more about birds than I do.

Denys Hemen, Operations and Facility Manager at the Audubon Center at Debs Park, says that adding herbs to your bird bath is just a bad idea all round.

“First of all, some herbs contain oils,” Denys explains, pointing out that, if those oils are released into the water and a bird then gets into the bath, there is a high likelihood of feather contamination.

Most birds’ feathers interlock with one another “almost like a zipper”, he adds, creating a waterproof protective layer around the body. When oil contaminates the feathers, it can interfere with that interlocking structure, allowing water to penetrate through to the bird’s skin. This can cause hypothermia.

There’s another problem, too: contaminated feathers can affect a bird’s ability to fly. Oil can weigh the feathers down, making it harder for a bird to get lift. More seriously, Denys says, contamination can damage the interlocking feature of wing feathers to the point where a bird may be unable to fly at all.

If that weren't enough reason to stop adding herbs to bird baths, he adds that leaving leaves sitting in water can cause them to wilt and rot, creating dirty (and stinky) water that can itself become a feather contaminant. Which is, yes, a fairly compelling reason to resist the urge to turn your bird bath into a tiny botanical pond.

If you want to attract more birds, the good news is that you don’t need to get particularly creative. According to Denys, the priority should simply be clean water. “Bird baths should be cleaned, rinsed and sanitized every few days and, if possible, left to dry between uses,” he says.

You can also make a bird bath more appealing, Denys notes, by placing it somewhere birds feel safe and where they have a clear view of their surroundings. And if you really want to add a little movement, a small solar-powered fountain like this one can help catch birds’ attention without putting anything extra into the water.

I know, I know; a handful of rosemary, a sprinkling of basil or a carefully curated collection of floating leaves sounds far more exciting an addition to a bird bath than plain old clean water. But if it keeps our garden birds safe, I’ll take boring every single time.
