Satellite photos show that between 2009 and 2018, the penguin population dropped by about 10%. That’s more than 20,000 adult penguins gone in just nine years.

“Penguins are already among the most threatened birds on Earth. The emperor penguin’s move to “Endangered” is a stark warning: climate change is accelerating the extinction crisis before our eyes. Governments must act now to urgently decarbonize our economies,” said Martin Harper, CEO of BirdLife International.

The white-tipped sicklebill uses its extremely decurved bill to reach inside sharply curved flowers, allowing it to drink nectar other nectarivores cannot reach. It is also a ‘trapliner’ — repeating the same foraging circuits, visiting favourite flowers along its particular route.
