I always love learning about new birds. The flightless Takahē is native to New Zealand and for many years was thought extinct. They were rediscovered in 1948 in a hidden value on the country's southern island and scientists are trying to boost the population. Gorgeous bird.

Here's a brief piece on them from TKSST:
When I was living in Vanuatu, I kept hearing a bird that made a sort of Woop-Woop noise. I never laid eyes on one and when I asked locals what they were called, I was told, "We just call them Woop Woop birds." Wish I'd had the Merlin bird ID app back then.
