[Rockhounds] Puffin beaks are fluorescent and we had no idea

[Kreigh Tomaszewski]

A scientist in England has made an enlightening discovery about Atlantic
puffins — under a UV light, their bills glow like a freshly cracked glow
stick.

"It was sort of discovered by accident," said Jamie Dunning, the
ornithologist who first saw the beaks light up.

Dunning normally works with twites, another type of bird, but he had been
wondering if puffins had Day-Glo beaks for a while, since crested
auklets — seabirds in the same family — also have light-up bills.
