In this September 26, 1997, file photo, a handler holds Tuatahi, a 3 week old Kiwi bird, the first kiwi born at Sydney's Taronga Zoo for more than 26 years. Scientists say they have sequenced the genome of the brown kiwi for the first time, revealing that the shy, flightless bird likely lost its ability to see colors after it became nocturnal tens of millions of years ago.
