If you explore the streets of West Tokyo on Maps, you may run into a row of people just standing and looking at you. They may come across as people just staring at the Google’s Street View crew out of curiosity, except all of them have their pigeon masks on. Aside from the legitimate question of ‘where did they even get so many pigeon masks to begin with?’, it’s all rather inexplicable and unsettling.
As it turns out, the pigeon people were locals who knew about the Google crew, and wanted to appear in the final photo of the street. It’s all rather harmless and fun, provided you knew the explanation.
