I just thought I would share this. A few years ago we bought a bird feeder. I now feel like I am feeding an army of birds from sparrows, robins, blue tits, blackbirds and finches. They are costing me a fortune but are a delight to watch. I live in an urban area.
I had to remove the water bowl from the feeder due to pigeons sitting in it to reach the food despite me having a ground feeding dish. It meant the feeder developed a lean. So I removed it and put it on the patio wall so they still had water. Then the bird bathing began, in the tiny dish, blackbirds squeezing themselves into it.
I have now upgraded and we made a DIY self filling bird bath (using a solar pond pump) because it is like I am running a bird spa! They queue up to get in, edge closer to force the other birds out. Sparrows bathe together in a little group. One blackbird was in there for 8 minutes, preening his feathers. Adorable. Then they sunbathe on the lawn. When I first saw it I thought something was wrong, a paralysed bird with its wings spread, a docile look on its face. No, just soaking up some sunshine.
I may not have a very pretty garden but I have the prettiest visitors. The cats have almost completely stopped coming as I have a cat detector thing with the hose attached. It worked for me.
