Herbert Edward Forrest, The Zoologist (1900)
“ Perhaps for the first few evenings the total assemblage will not be very large, but as successive families realize the necessity of quitting their nesting-places the congress increases night by night. Very few sights in the bird-world are so impressive as one of these great gatherings of the clans. About an hour before sunset the first flocks begin to arrive at the appointed place. These do not settle down at once, but continue to fly around; soon other flocks arrive in quick succession from all points of the compass, till the heavens are literally darkened by the cloudy masses of birds. ”
