Pigeons! Isn't it interesting that humans domesticated them and then kind of forgot about them because we stopped needing them to deliver messages for us. Now pigeons just hang around humans being like 'we're here!'. Kind of sad really! We often have pigeons walk into the shop, do a lap and then walk out again. They never buy anything, but they're cute browsers nonetheless. Stick this pigeon sticker it to any smooth flat surface, like your water bottle, iPad or reuseable coffee cup.
