Greys are generous and altruistic

[Pajarita]

I am giving you three links because one explains it in common language, another has great pictures and the third is the actual study with all the details. But, basically, what they discovered was that African Grays (the study worked with grays and macaws) would give their own 'token' (which would get them a treat) to not only their friends but also any other gray that did not had a chance to get one even though it brought them NO reward in any way (but they did 'help' their friends more often than the non-friends). And there are still people who doubt these animals can love! If you ask me, they have finer feelings than most people! But I would have liked to have been able to see the gender of the birds in the study... I saw a male taking a token but I could not tell -because of the angle the picture is taken- if the one receiving the token was a female or another male, and I think that should have bearing or, at the very least, be mentioned in the results. Problem is (as with most bird studies) that the people actually doing the study do not know enough about parrots so they don't pay attention to details we, as bird lovers and keeers, would.
