Kiwi scientist makes a twitter breakthrough | Stuff.co.nz

Bird watchers have long waxed lyrical about the benefits of listening to birds, but now a recording of their tweets has led a Kiwi ecologist to a scientific breakthrough.

Dr Efford said the discovery could be used in the future to help measure dolphins, whales, and other animals that lived in areas which made them difficult to count.
