Then, as they came to where the trees ended, and blackbirds, before roosting, began to give the alarm in earnest, some first starlings flew out of the sky. Over against the old man and his granddaughter the vast mansion reflected a vast red; sky above paled while to the left it outshone the house, and more starlings crossed. After which these birds came in hundreds, then suddenly by legion, black and blunt against faint rose. They swarmed above the lonely elm, they circled a hundred feet above, until the leader, followed by ever greater numbers, in one broad spiral led the way down and so, as they descended through falling dusk in a soft roar, they made, as they had at dawn, a huge sea shell that stood proud to a moon which, flat sovereign red gold, was already poised full faced to a dying world.
Once the starlings had settled in that tree they one and all burst out singing.
Then there were more, even higher, dots against paler pink, and these, in their turn, began to circle up above, scything the air, and to swoop down through a thickening curve, in the enormous echo of blood, or of the sea, until all was black about that black elm, as the first mass of starlings left while these others settled, and there was a huge volume of singing.
Then a third concourse came out of the west, and, as the first birds swarmed upon the nearest beech, these late comers stooped out of dusk in a crash of air to take that elm, to send the last arrivals out, which trebled the singing.
The old man wondered, as often before, if this were not the greatest sound on earth. Elizabeth stood quiet. The starlings flew around a little and then, as sky faded fast, the moon paled to brilliance, and this moment was over, that singing drooped, then finished, as every bird was home.
