Spanish researchers have discovered that baby European Rollers have an unconventional method of deterring potential predators. The young birds will "vomit a smelly orange liquid when scared by predators." The act serves two purposes. First, the stinky puke may disgust predators from further harassing or attacking the nestlings. Second, the smell serves as a signal to the parent birds that the nest is in danger. The parent birds approach the nest with extra caution when the babies have vomited. Not exactly cute -- but pretty neat, right?

We've recently added three new Birdorable birds from the roller family: the European Roller; the Lilac-breasted Roller; and the Blue-bellied Roller. There are twelve species of roller extant today. Rollers are similar to crows in size and shape, but certainly not in color. Rollers are colorful in appearance, and more closely resemble bee-eaters and kingfishers in this way. In fact, they are closely related to both of these families, taxonomically speaking. Rollers get their name from their unique breeding displays, where male birds swoop, dive, and roll through the air. Check out our original Roller apparel and gifts featuring these three new birds:
