Speaking of magpies

[Susanne Gardiner <>]

me again:

 

According to wiki the Pidgeon-Mirror-Test (self-awareness) was published in Science in 1981. According to the respektive German site, there were some doubts about the actual tests.

oops, send this to Philip directly, here for the list:

 

Sorry, I should have been more specific. This was in the 1980s and pretty much the same experiment setup as with the magpie. Pidgeons with dot and mirror in a cage. Still have a recollection of the picture that came with the article.

PS: Can't find it at the moment (the German word for pidgeon is a homonym for deaf people and Google can't distinguish)... but turned up another study from Japan, where Pidgeons recognise themselves in mirrors and video-recordings, even when the image was not live, but shown to them later.

It's in German and only a short newspaper story, not much depth: http://www.krone.at/index.php?http%3A//www.krone.at/krone/S25/object_id__104296/hxcms/index.html

There are several other studies with pidgeons and their ability to think abstractly and to recognise various things (Humans, Art....).

 

In this article from 2006 it is already mentioned that magpies have the context of self.

I don't know about that. Just because someone found out the same thing about pigeons.... some "dirty" pigeon tried to clean itself after seeing its reflection in a mirror.

 

That doesn't mean the bird realised it was looking at itself. A lot of bathing behaviour in birds is by social facilitation, they like to do it together. Beside it would take many repeats of an observation like that, to be convincing.
