Crows donât just recognize individual human facesâthey can remember them for years and apparently tell other crows about them.
Researchers have tested this in a rather memorable way: by wearing masks.
In one long-running experiment, researchers captured and briefly handled wild crows while wearing a particular mask. The birds were released unharmed, but unsurprisingly, they werenât especially fond of the face they associated with being captured.
Later, people wearing that same mask walked through the area without bothering the birds at all.
The crows noticed.
They scolded the masked person, followed them, swooped nearby, and recruited other crows to join in. Meanwhile, people wearing a different, neutral mask generally received much less attention.
But hereâs where it gets especially interesting.
As the years passed, more crows reacted to the threatening faceânot fewer.
Some of those birds had never personally been captured by the researchers.
They had apparently learned from other crows that this particular human face meant trouble.
Young crows can learn by watching their parents and other members of the group, while adult crows pay attention when other crows sound the alarm. In other words, information about a potentially dangerous person can spread through the local crow population.
And they donât forget quickly.
Research has shown that crows can retain those associations for years, recognizing a face connected with a bad experience long after the original encounter.
That ability makes a lot of sense when you consider how crows live.
Theyâre highly social animals, and knowing which humans, predators, locations, or situations are dangerous could make the difference between surviving and making the same mistake twice. Learning from another crow is even betterâyou get the warning without having to experience the danger yourself.
So when several crows suddenly start yelling from the trees as someone walks past, it may not be meaningless bird noise.
There could actually be a neighborhood crow story behind it.
And apparently, once youâve earned a starring role in that story, recasting the villain may take quite a while. đđŠââŹ
