During the breeding season, puffins develop photoluminescent structures on their bills.
Happy Puffin Day - love the science and thanks for the link to the paper - whether its photoluminescence for mating or feeding chicks its pretty awesome.
Birds will never cease to amaze us.
Glowing bills…one more reason to love puffins!
Cool!
