They're working on it. :-)\n\nWhat they do know:\n\n"The results [of a recent study] turned up [that] ... it bypasses the known brain circuitry for consciously analyzing and mimicking other people’s actions."\n\n"This might be part of a more general phenomenon of unconscious signals that serve to synchronize group behavior, the authors of the Neuroimage paper wrote. “Such synchronization could be essential for species survival and works without action understanding, like when a flock of birds rises to the air as soon as the first bird does so—supposably as it notices a predator.”"\n\nTry the article in the sources for more.

Because they lose all sense of direction. That where the saying came from about people; "She running around like a chicken with it's head cut off".

actually, they walk on their claw like feet providing minimal surface area. so, they are not caught in thier own web.

They need straight sightlines.  Their periphal vision is atrocious.  Trees block their field of vision.

Both at the same time!, lightning has been photgraphed heading upwards from trees, at the same time leaders head downwards as well, where they meet a lightning strike occours.\n\nThats why when you are out in the open during a storm and feel your hair standing on end - panic and get down, a leader may be leaving your head!

Because they are predators. Animals which do not rely so much on their hearing for hunting tend to have ears that are positioned to pick up sound equally well through 360 degrees as an early warning system.

If it's a medium-sized, rather ugly mottled black/brown bird that congregates in the evenings to form a roost community then it may be grackles.  They have no song, just a rather raucous squawking call and when they gather by the hundreds in the trees nearby, they are a nuisance of the first order.  Much worse than pidgeons.  We have them in Texas and I believe that at different times of the year they plague most of the US.

Its part of their flying rotation.. One side is always longer because the tired goose goes to the back of the line...\n\n\nWhen the head goose gets tired, it rotates back into the wing and another goose flies point.

These birds do not all have the same foot posture.  For example ostrich feet sit flat on the ground for walking while songbirds toes are designed to be able to curl and grip branches when they perch.  Birds like eagles have raptorial feet with long talons for capturing prey.  \nHope this helps

It's because it makes their fur stick to them and they hate the feeling of it. It has to do with the way the fur mats up. I am not sure why!

The geese rotate who is at front in the formation. The lead bird is going to tire the fastest so they all share that position.  Geese do not necessarily have one lead bird that they all follow. Each indivdual goose knows they way to their hibernation area so when it is their turn to lead they do not need any other goose to tell them how to get there.

It depends on the bird. As a general rule, predatory birds have their vision focussed forward (eg, owls, hawks, eagles) while herbivorous bird have a wider arc of vision, including to the sides of their bodies. (That is, the higher on the food chain a species of bird is, the more likely thay have specialised to see forward of their bodies.) In both instances, the bird's brain combines and interprets the world in a useful way for the bird. They are not 'seeing forwards' or 'seeing sideways' - they are seeing in a way useful for that species. \n\n(As a matter of comparison, human females interpret a wider arc of vision than male humans - hence the reason why men are sometimes described as not being able to find something 'right under their nose'. Women don't "see sideways", their brains just interpret visual information from a wider lateral angle.)
