A tagged shorebird that flew more than 7,400 km from South Australia has been spotted on the remote Narcondam Island in the Andaman and Nicobar archipelago, an expert said on Tuesday.

The bird, a Sanderling, was photographed by G Thikanna, an assistant sub-inspector with the Andaman Police, during a posting on the island. Mumbai-based ornithologist Dr Raju Kasambe said.
