Police responded to a clear call for ‘help’ late Tuesday that came, it turned out, from a parrot. 

A package deliverer heard what he believed to be the sounds of a woman screaming for help on his route Monday evening. The Oregonian reports that the man called his wife, who in turn called the police, reports Newsweek.

A police officer arrived on scene as the UPS driver waited outside the house where he heard the screams.

The officer found that the screamer was in fact a parrot named Diego, who was, by all appearances, doing just fine.

While there is absolutely no reason to believe this is a widespread phenomenon, this isn’t the first time a parrot crying ‘help’ summoned the police. Last year, police in Germany responded to what sounded like a child in distress, only to find a parrot. Several years before that in New Jersey, a bird that learned new registers and words from English- and Spanish- language television was also mistaken for a woman crying for help or an abandoned child.

Parrots, along with some other species of birds, are vocal learners. Rather than having a song inflexibly hardwired into their brains, parrots can adapt and pick up on other sounds and dialects. All vocal learner birds have a part of their brain called a ‘song system,’ what the Audubon Society describes as an ‘inner shell’ of brain tissue that enables birds to adapt their song. In parrots, there is a unique outer layer of cells around this shell that gives them their heightened powers of mimicry.
