The kakapo

The kakapo is a strange little flightless bird native to New Zealand. Sadly there are now only 126 kakapo left in conservation areas, where they eat a range of plants. But researchers who have been studying ancient poo samples have recently found that around 900 years ago kakapo ate a lot of pollen from a root parasite known as "Hades flower". The two no longer exist in the same place and Hades flower is also rare, which begs the question - were the birds responsible for pollinating it? Further research needs to be done, but it's an interesting conservation link.
