Professional violinist and amateur conservationist Julia Robinson-Dean was thrilled when she found a new species of bird in Indonesia. But excitement gave way to a serious ethical dilemma. Her photos, notes and DNA samples were not enough to give the bird a name, which meant it could not be given international protection. When scientists agreed a specimen was required, Robinson-Dean was put in the position of having to return to the island and kill one of the birds she had found in order to help them.
