Sparrows having a communal bird bath in the garden today

This is the second time I've seen the sparrows do this. The first time was about a month ago and I tried filming them but something didn't work out right and the videos I took were blank. Today I managed to shoot three short videos of them enjoying their bath, splashing around. When they're done, there are huge drops of water all over the place. They are an endless source of entertainment--I love watching them.
