Now that winter has properly arrived, we are getting a number of queries here in wildlife enquiries about how to keep bird baths ice free. Here are some top tips!
I hope these tips prove useful!

Hi Ian, yes, it's a problem when it's -10C like this morning!
Another idea I have found works well - I've punched 4 holes in the sides of a small tin can for air flow ( carefully as the metal is very sharp!!), then put a tealight candle in, with the water dish on top. Keeps it ice free for hours. Last winter a song thrush spent ages sitting on the side of the dish- keeping warm!
In the dim and distant past when I was young, my mother always put one spot of glycerine (the sort you use when you make icing for cakes) in the bird bath and it never froze over. Does anyone know if this would be ok? I keep thinking I should try it. As far as I remember no birds ever came to any harm. This-morning I had to go out 5 times to my two bird baths before they were completely ok, so I have been tempted to give the glycerine a go!
