Note * — THE ILLUSTRATIONS (continued 2)

Part of the material used in this chapter has already appeared in the author's work entitled "Birds of the Rockies," but it is here printed in different form, that of a monograph, with a number of additional facts. The writer feels that the readers of the present volume will relish at least a taste of bird study among the alpine heights of the Rocky Mountains. The article is reprinted from the "Denver Post," whose courtesy is hereby acknowledged.
