Doves do not seem to care if it is raining or not they are going to eat their bird seed.
I will not see any other birds in sight when it is raining just the doves. The water in the feeders can not drain fast enough so they end up holding water. The birds go dunking for seed because they want to eat.
This particular day I found them splishing and a splashing. I am quite lucky I was able to capture this on camera. They seem to dive down for a seed and come up shaking the water off which is part of the splashing.
Even birds like to have a little fun
