Indeed, if the superfluous songsters did not go away (and the Wild Birds’ Protection Act remained in force), we should be smothered with thrushes. I know, for instance, of a little “place” in the country, some thirty acres all told, garden, shrubberies, orchards, spinneys, and meadow, where birds are tempted to come by the planting of fruit bushes and strawberry-beds in all directions, by the numbers of elder trees and mountain ash set out, by the encouragement of blackberries and dog-roses wherever they can be allowed to grow, and where birds are tempted to stay in winter by liberal scatterings of grain-foods and table-scraps. Within this little estate there were one year forty nests of thrush and blackbird. Now supposing these birds bred only once in the year, which is very improbable, and reared only three birds apiece, which is equally so, and that half were killed or died during the year, there would then be left twice as many thrushes as in the year before. Forty pairs would become eighty; eighty, a hundred and sixty; a hundred and sixty, three hundred and twenty, and so on till five years later there would be over ten thousand pairs of thrushes (allowing all along for the same excessive proportion of casualties), breeding on thirty acres, and if each pair hatched five birds, there would be fifty thousand thrushes all together!
So it is well that thoughtful Nature leads off vast colonies every year. Those that happen to stop to rest on Heligoland stop there for good and all, for the Heligolanders eat them. Those that get farther fare no better, for everybody eats them. Belgian and Dutchman, Frenchman, Spaniard and Portuguese, German, Swiss, Italian. And it is really a
