Flights of starlings have a way of flying which is theirs alone and seems as governed by uniform and regular tactics as a disciplined regiment would be, obeying a single leader's voice with precision. The starlings obey the voice of instinct, and their instinct leads them to bunch into the centre of the squad, while the speed of their flight bears them constantly beyond it; so that this multitude of birds thus united by a common tendency towards the same magnetic point, unceasingly coming and going, circulating and crisscrossing in all directions, forms a sort of highly agitated whirlpool whose whole mass, without following a fixed course seems to have a general wheeling movement round itself resulting from the particular circulatory motions appropriate to each of its parts, and whose centre, perpetually tending to expand but continually compressed, pushed back by the contrary stress of the surrounding lines bearing upon it, is constantly denser than any of these lines, which are themselves the denser the nearer they are to the centre. Despite this strange way of swirling, the starlings cleave through the ambient air at no less rare a speed and each second make precious, appreciable headway towards the end of their hardships and the goal of their pilgrimage.
