← Great tits join mobs with neighbours they know

"One: birds join their neighbours because they think: 'My nest could be next.' "Or they join because their neighbours have joined their mobs before, and they know that if they don't reciprocate, they'll be left alone next time. It's sort of great tit tit-for-tat."

Do they really make that reasoning or is it so that birds who have this behaviour baked in their genes have more chances for survival, without 'knowing' why they behave so? A bit like people who blindly follow charismatic leaders without really understanding why they do that.

Great Tits mob because the Great Tits that don't are extinct... or very lucky
