Hi Dave that’s a coincidence, I’ve recently dug out an old bird bath and filled it with water and the sparrows have been drinking from it already. I’ve also hung bird feeders in the garden and coconut shells filled with suet and the birds empty all of these in a day! I’ve read that once you start feeding birds you have to continue as they become reliant on the source. I’m hoping to attract some blue tits as well as sparrows into the garden. It can be an expensive game !
