    I leave for work early in the morning. We have three large apple trees behind our house. One morning without warning I opened the service door on our garage to leave and saw something so amazing I stood still in my tracks just to watch.There were maybe a dozen birds flying back and forth carrying apples away from the ground under the middle apple tree. And, on top of the apple tree was a single bird picking apples and dropping them to the gound as fast as he could.

    from this video I get the feeling that the birds had no ideea they were cooperating. the fact that both hands retracted at the same time obviously made the birds act at the same time. had there been a wall between them, i suspect they would have acted the same way

    it pulled the string because it was put in front of it, this test was stupid and flawed!

    I like the research direction however on the basis of the methodology and results of your work I am personally not convinced that these rooks were co-operating. I look forward to seeing future research.

    i agree, this experience should be repeated with the strings placed before the birds even saw them and then just leave them anywhere near to see what happens.
