THE NUMBER OF BIRDS IN THE WORLD. Records made in the course of a biological survey organised by the United States Department of Agriculture show that on an average there are about 224 birds for every hundred acres of land. It is estimated that in the northeastern and central States of America there are 82,660,089 robins, 69,300,833 English sparrows, 50,514,499 song sparrows, 33,815,491 cat birds, 29,640,739 chipping sparrows, 29,223,264 meadow larks, 23,796,086 house wrens. 23,378,611 king birds, and 22,126.185 blue birds’ or a total of 364,455,847 of nine species. It; reckoned that there must be 688,266,314 birds of all other species, so that the total for the north-eastern and central States is 1,052,722,161. But this enorxnous number is about, a quarter of the bird life of the whole United States, and, reckoning the same figures as a basis for estimating the bird population of the world, it. is supposed that there must be something like 75.000 millions birds, or forty times the total number of human beings on the earth
