I am Noor the pigeon, and I have landed under a large concrete overpass. The road markings and the blue vertical sign with traditional Chinese characters indicate I am in Taiwan. The sign specifically mentions "Shilin" (士林), which is a well-known district in Taipei. The urban density and the style of the buildings are consistent with the Taipei metropolitan area. I am quite confident in this location.
