Jackdaws Identify "Dangerous" from "Safe" Humans
Don’t think that humans have a monopoly on “social distancing”—because even birds are prudent in physical distancing, depending on the contingent hazards that they perceive nearby.1,2 And birds, like humans, warn one another about the dangers they see, and how best to avoid them.2-4

Consider Europe’s crow-like bird the jackdaw that can identify which humans are “safe” and which humans are “dangerous.”

Jackdaws can identify “dangerous” humans from listening to each other’s warning calls, scientists say. The highly social birds will also remember that person if they come near their nests again, according to researchers from the University of Exeter [in Devon, England].2

Recent research shows how these birds deal with danger.

Here, we tested whether wild jackdaws (Corvus monedula) use social learning to recognize dangerous people. Using a within-subjects design, we presented breeding jackdaws with an unfamiliar person near their nest, combined with conspecific alarm calls [warning that this human was dangerous]. Subjects that heard alarm calls showed a heightened fear response in subsequent encounters with the person compared to a control group, reducing their latency to return to the nest. This study provides important evidence that animals use social learning to assess the level of risk posed by individual humans.3

Specifically, the jackdaws were experimentally observed on how they reacted to jackdaw signals,3 giving information about approaching humans—namely, which humans were potential threats that needed to be quickly avoided.2

Audio recordings were played, to signal if a new human was “safe” or a threat.

In the study, a person unknown to the wild jackdaws approached their nest. At the same time scientists played a recording of a warning call (threatening) or “contact calls” (non-threatening). The next time jackdaws saw this same person, the birds that had previously heard the warning call were defensive and returned to their nests more than twice as quickly on average.2

In short, the experimental observations show that wild jackdaws can remember which humans are nice (or not) to them. This shows that wild jackdaws report this evaluative information among themselves.

Not only do the birds promptly take appropriate defensive actions, they recall later which humans they were warned to avoid.2,3

These birds don’t rely upon evolutionary “good luck” to avoid dangerous people. These jackdaws are given and utilize wisdom, with a little help from their friends.

God Himself made these communicative birds smart and mutually helpful.5
