Century-old clues reveal hidden threat to Australian songbird
A hidden threat facing one of Australia's most iconic birds has been uncovered in a new study. The critically endangered regent honeyeater once numbered in the hundreds of thousands, but their population has dwindled to fewer than 300. By analysing the DNA of museum specimens more than 100 years old and comparing it to modern samples, the team discovered that despite a population decline of 99 per cent, this has not been entirely mirrored by genetics. The bird has lost 9 per cent of its genetic diversity.
