The Lord Howe gerygone (Gerigone insularis) was a bird endemic to the Lord Howe islands, part of New South Wales in Australia. It was known as the “rain-bird” due to its activity after rain fall. This was because there were more insects active then, and these birds were insect eaters.
In 1918 a shipwreck occured on the island and this accidentally introduced black rats. Which most likely caused this birds’ extinction. The last species was seen in 1928.
