Wondering at the reticence of the Kansas sparrows, I wrote to a friend living in Springfield, Ohio, my former home, and inquired what the song sparrows were doing in that locality. His reply was that, as usual, they had been singing with splendid effect on almost every day after the middle of February. What is the reason of this difference between the eastern and western birds? They are, according to the systematists, the same type, and yet they behave so differently. The solution of the problem is, after all, quite simple. In Kansas the song sparrows are winter residents exclusively, passing farther north when the breeding season approaches; only at rare intervals does a pair decide to remain in the state throughout the summer; whereas in the Buckeye state these birds are permanent residents, remaining throughout the year, and therefore they feel sufficiently at home to tune their lyres at all seasons. On the other hand, being only winter visitors in Kansas, they do not seem to be able to overcome their shyness; either that, or their wind harps are out of tune. As a matter of fact, migrating birds seldom sing a great deal in their winter homes, their best lyrical efforts being husbanded for their breeding haunts. I once spent part of the month of June in Minnesota, almost directly north of my Kansas field of research, and there found these charming minstrels as tuneful and affable as the most exacting bird lover could wish. Perhaps some of the very sparrows that spend the winter in silence in northeastern Kansas trill their finest arias in their summer homes on the shores of Lake Minnetonka or in the boggy hollows in the neighborhood of Duluth. When I first began to plan for moving back to Ohio, I was foolish enough to fear that the song sparrows of that state might have changed their habits during the years of my absence, and that I should be disappointed in them: but no need of borrowing trouble on their account, for they were the same blithe and familiar birds, trilling their sweetest chansons in the trees in the residence portion of the town in which I lived. And sing! Were there ever birds with more dulcet tones, with finer voice register, or with a greater variety of tunes in their repertoire?
