puffins

The Atlantic Puffin's colorful beak plates absorb ultraviolet light and fluoresce under blacklight, a little-known trait of the seabird. Nature and wildlife enthusiasts are sharing the biology factoid, which adds to the bird's reputation as one of the most striking species of the North Atlantic. The discovery highlights how much remains to be learned about familiar animals.

Nature photographers are sharing pictures of two puffins taken in Iceland in 2023, using a photo suggestion format that invites others to post matching images. The shots highlight the seabirds that draw wildlife enthusiasts to Iceland each summer, and the theme is being picked up across nature and bird photography communities.
