Those Observant Parrots
Parrot keepers are well aware that individual birds often “take to” one person or to people of one sex only, and respond with aggression or fear to others. Long –term pet parrots most definitely react differently to the various people living in the household – seeming to know what they can “get away with” with one person, when to expect a scratch on the head from another, and so on.
The Brightest Birds
Wildlife biologists at the University of Washington have recently (August, 2008) confirmed that crows do indeed recognize and remember the faces of individual people. Crows and their relatives – jays, ravens and magpies – are among the most intelligent of birds, and are often compared to parrots in this regard. I’m quite sure that the results of this research would be duplicated if conducted on parrots.
Researchers wearing masks designated as “dangerous” trapped, banded and released crows on the university’s grounds. While subsequently walking about the campus wearing the “dangerous” masks, the researchers were consistently scolded and mobbed (harassed) by crows….when unmasked or wearing “neutral” masks, the researchers went unnoticed. When paired with “neutral” mask wearers on walks, only the “dangerous” researchers drew the crows’ wrath.
Birds Teaching Birds
What’s more, although only 7 crows were trapped (the experiment was later repeated with a larger sample), 47 individual crows scolded the researchers. Although crows will respond to the alarm calls of others, in some instances the originally trapped crows were not present when others sent up the alarm – obviously the trapped crows had somehow passed along their new-found knowledge to their neighbors!
Implication for Conservation
We’ve long known that fledgling birds will imprint (bond with, to the exclusion of their own species) upon general human characteristics…while hand-rearing barn owls and other species destined for release, I always work from behind a curtain, and such is standard protocol at most zoos. This study, however, offers the first concrete evidence of individual face recognition.
I’m sure you parrot owners have many stories of your pets’ own remarkable abilities.
