Herbert Edward Forrest, The Zoologist (1900)
“ They now proceed to execute in the air a series of complicated evolutions, like regiments of soldiers on a review day—charging forwards, wheeling to right and left, crossing and recrossing over and under, converging and diverging, coalescing and separating, till at last, just after sunset, as if by one consent, the whole body of birds descends like an avalanche, with a mighty rushing sound of wings, and covers every tree, shrub, and reed with a living freight so heavy that they bend almost to the earth beneath their burden. ”
