_Keeping Migration Records._--More than thirty {80} years ago the United States Government put into operation a plan for collecting and tabulating information concerning the dates on which migratory birds reach various points in their journeys. More than two thousand different observers located in various parts of the country have contributed to these records, many of the observers reporting annually through a long series of years. As a result of this carefully gathered material, with the addition of many data collected from other sources, there is now on file in Washington an immense volume of valuable information, much of which, in condensed printed form, is obtainable by the public. This work was in charge of Professor Wells W. Cooke, Biologist, in the Biological Survey of the United States Department of Agriculture until his lamented death in the spring of 1916. Who will take charge of it hereafter is not yet determined; but students may obtain from the director of the Survey migration schedule blanks upon application, and bulletins describing the emigration habits of various North American birds. {81} Watching for the annual appearance of the first individual of each species is most fascinating occupation.

W. Henshaw, Chief Biological Survey, Department of Agriculture, Washington, D. C. {82} CHAPTER V THE BIRDS IN WINTER With the approach of winter the country loses its charm for many people. The blossoms and verdure, so common yet so beloved by all, have departed, and only the brown expanses of dead grass and weeds relieve the blackness of the forest trees. Even ardent nature lovers have been known to forsake their walks at this season when the songs of the birds have ceased and the forest boughs give forth only sobs and shrieks as they sway to the strength of the north winds. _A Good Time for Field Walks._--Nevertheless winter is a good time for the bird student to go afield. If the wild life is less abundant, so is the human life, and you have the country almost to yourself. If you but say in your heart, "I will go and see what may be {83} found," you will later rejoice, for with the falling of the leaves many of Nature's secrets, which she has jealously guarded through the summer months, stand revealed. Among the naked branches of the briars you may find the Catbird's nest which defied all search last June. It will be a comfort to learn that the bird really did have a nest just about the place you thought it was located. Many other pleasing surprises await you in the winter woods.
