No decent picture sadly, but I've just learned that wood pigeons take showers. I know birds bathe, but I never knew any of them showered.
I'm currently watching a wood pigeon sitting on an exposed tree branch across the road; The heavens opened, and he started putting a wing in the air, like when a human puts an arm in the air in the shower to wash under their pits. He'd alternate wings so both sides got a good dousing. It was comical, I expected him to grab some soap and start singing. Once the rain stopped his wings went down and he started preening under his arm pits wing pits.
I surprised the Google AI no doubt with the batsh1t enquiry "Do pigeons shower?" And RSPB said yes, it is a thing! Wood pigeons prefer to use falling water to shower in rather than bathing in pools like other birds. They've been seen using public fountains in the same way. I'm not sure why but that's delighted me.
