Until the bird actually flies away there are three birds on the branch.Originally Posted by pleasurekerry

A bird cannot be considered capable of making decisions now about postponed future actions. So in making the decision to fly off, it then immediately flies off. Of rather, it flies off, thus making the decision to do so, apparently on impulse.
So to answer the question, 2

What do you mean that birds can't make decisions about postponed future actions....................how about birds who wait for a flock to fly away together? Surely it isn't a case that thousands of birds decide to fly all at the exact same time. So that means that they make a decision to fly together when they are ready to do so. I'm not really well up on birds and how they make these decisions but they do seemed planned.A bird cannot be considered capable of making decisions now about postponed future actions.

If that is the case then my answer might be right.

The truthful answer is none. The other two birds would both fly off as well because birds don't like to stay if someone else leaves.

Two, because there are three birds, one flies off and that leaves the other two sat on the branch, assuming that they hadn't decided to fly off themselves.
Just stating the obvious, like.

With miliseconds of difference in the decision making, they do decide at more or less exactly the same time - but because of each other. That is exactly why birds, like fish swarm and can move together. They decide to move exactly because the one beside them moved, without premeditation. We protect our ideology of individualism in our society by modelling their behaviour as thousands of separate decisions, where as it works much better as a single decision taken all-but simultaneously by thousands of birds.....or fish. How that is done, is that they are committed to being together. They make themselves vulnerable to each other by committing unreservedly to the flock. Consequently they cease to operate as entirely discrete individuals.The mechanism of individual decision making is still there, but the substance is gone.
birds who need birds are the luckiest birds...like people.
