A previous study that measured a large number of seabird bones from the Chatham Islands found three size categories. The largest bones belong to
A number of biological specimens in Te Papa’s collection, particularly old specimens, lack information about when and where they were collected. This information may have been lost since the specimen was collected or was simply not recorded at the time. However, all is not lost! Sometimes we can use DNA
Little spotted kiwi only occur in New Zealand, where there are around 1500 individuals remaining. They are the smallest kiwi species, about the size of a bantam hen, and are very susceptible to predation by introduced mammals, such as stoats and dogs. Today they survive on predator-free offshore islands and
