Babies of the Eurasian roller bird species vomit a foul-smelling orange liquid as a defense mechanism against predators, biologists have discovered.
Offspring of the bright-blue jackdaw-sized bird yak the milky fluid when they are frightened in their nests, according to journal Biology Letters. Covered in vomit, the nestlings become less attractive as a snack, the findings say.
So what's the big deal? I had the very same defense mechanism while bar-hopping to my heart's desire in my 20s. *
