Has anyone else seen water in bird baths/small ponds turn a red colour? I’m guessing this isn’t good and I plan to clean and refresh mine. Perhaps someone can explain why this has happened and what it is? I’ve never seen this until recently. There appears to be a red sediment too. I’m sure there are others interested in this too. I know I won’t be the only one with this problem.
One bird bath is on a pedestal and made of stone. The other is a large plastic plant saucer with a few stones in it and sited on the ground with planting around it. Chatting to a friend with a small pond today, she has this in her recently filled with fresh water.
I guess my next questions are, how do you stop this happening again after cleaning and refreshing the water and can this harm the birds that bathe and drink from it. Could the birds even have brought this in?
Finally, for everyone looking forward to the return of BBC2’s Springwatch tonight I hope you enjoy it. I’m looking forward to it myself especially as my garden has been short on nests to watch this year. Oh yes… and I’m very interested to hear about the Beavers 🙂
UPDATE 2020: There’s some interesting chat and info in a blog by BIRD life on Red Algae In Your Bird Bath? This Is What To Do for further reading.
