I discovered a tree kangaroo that had only been seen once – by the man who shot it in 1928

I want people to be excited about the animals I find and get them involved in conservation

I am a British tourist, and I spend my holidays searching for species that are believed to be extinct. On my last trip to Papua New Guinea in 2022, I found a Louisiade pitta bird, which had been the focus of failed professional expeditions for years. It hadn't been seen alive since 1898.

We went around playing recordings of a related pitta, which sounds a bit like a chicken being strangled, until we received a reply. Imagine if you went around a haunted house rattling chains and then you heard a ghost rattling them back - that is what it was like.
