Researchers wore a unique "dangerous face" mask as they captured and banded and released crows around Seattle. The researchers then drove to different areas wearing the mask. Crows that had never been banded recognized the "dangerous face," and started mobbing and scolding the researchers. Both relatives and strangers joined in the scolding and mobbing, which could occur over a mile away from the original banding.
So, through some sort of social media, the captured crows spread the word about the dangerous masked banders and all their crow friends joined in on the payback.
This I believe, as crows are known as very intelligent creatures and probably do have access to Facebook.
I did, however, find this very disturbing:
"...other social, long-lived species that live closely with humans might also share information in a similar manner. Possibilities include animals such as coyotes, raccoons, gulls, pigeons and rats. All could practice a combination of social and trial and error learning."
The raccoons that I throw water on and scream at to get off the bird feeder are possibly imprinting my mean girl behavior and spreading the word to their buddies.
They could be planning a counter offensive as I write....
Clearly, I need to get start wearing a disguise around the LoveNest.
