Excerpt from Bird Guide, Vol. 2: Land Birds East of the Rockies, From Parrots to BluebirdsIt is an undisputed fact that a great many of our birds are becoming more scarce each year, while a few are, even now, on the ver of extinction. The decrease in numbers of a few species may be attributed chie y to the elements. Suoh as a long continued period of cold weather or ice stoma in the winter, and rainy weather dur ing the nesting season' however, in one way or another, and often unwittingly, man is chleny responsible or the diminution in numbers. If I were to name the forces that work 'nst the increase of bird life, in order of their importance, I should give them as an, the elements, accidents, cats, other animals, birds of prey, and snakes. I do not take into consideration the death of bitds from natural causes, such as old age and disease, for these should be counterbalanced by the natural increase.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
