The Crow: Which Is Mourning For Their Dead

The Crow are very intelligent. Research shows that they "mourn" the death of their community, recognize the faces of people who are a threat and "teach" them to other crows to be careful.

The habits of birds to honor their dead has been widely observed lately. Crows always observe and gather around a dead bird of their species, but until now we did not know exactly why. A study by the University of Washington recorded the behavior of birds after placing dummies with dead crows in various areas. At the same time, the research team set up three "dangerous" scenarios in the scene of dead birds. A man wearing a mask holding a dead crow, a man wearing a mask next to a hawk and a man wearing a mask next to a hawk holding a dead crow in front of him.

The rationale of the experiment was to examine, on the one hand, the mnemonic that crows have in remembering human faces, hence the specific masks on a case-by-case basis, but also to note which of the three risk scenarios they would react to the most. In any case, a crow (the one that controls the area) would show up and howl would attract an additional five to 11 extra birds of the species.

The loud cries of the birds continued for 10 to 20 minutes and then the ... ceremony ended. The crows reacted more strongly to the scenario of the man with the hawk, in contrast to the man who stood alone with the dead crow, which shows that they also realize the urgency of the danger, that is, a hawk and a man together in the same place pose a much greater risk to them.

A team of researchers from Oxford (UK) published in 2009 a study in the journal PLoS One online, which suggests that crows are animals with a form of analytical intelligence.

The study was conducted on crows, which in the wild are already capable of using tools to reach food. An experiment conducted in 2002 had already shown that a raven in captivity managed to invent spontaneous tools based on need, again for the immediate purpose of feeding.

The use of tracking tools - a tool for using another tool - has been observed in many primates and crows, according to research conducted in New Zealand.

An Oxford team, in turn, led a new study in seven captive crows. These crows have been tested in a series of tasks that require the use of three tools in a row to reach the food. The birds had to use a small tool, push the tool harder, so you could grab a third even bigger tool and finally get to a piece of food, if not impossible.

Five crows were successful, including four in the first attempt, without prior training. And an accurate analysis of the birds' behavior shows that they did not act by chance. When one bird supported one tool to get another, it always chose more than the previous tool.

This study demonstrates the ability never seen in birds but also emphasizes the importance of a careful approach in comparing cognitive skills. Intelligent behavior can be detected without necessarily very high mental abilities.

The findings show us that social age-old birds not only recognize danger, mourn the dead and warn other members of their society, but also manage to recognize the faces of people associated with danger even many years after the incident. A team from the same university conducted a similar experiment, putting a masked man to trap, tie up and then release crows in five parts of Seattle.
