S 8 THE GRASSHOPPER SPARROW. 



My two Columbus dates are April 24, 1902, and March 19, 1903, the 

 latter being the earliest of which I have information, a typical example of that 

 wonderful warm wave which amazed the oldest ornithological inhabitants. 

 Prof. A. W. Butler, in his "Birds of Indiana", records it as a rare resident in 

 the lower Wabash Valley and gives a few instances of its breeding in that state. 

 The instance recorded by Dr. Wheaton on the anthority of Mr. H. C. Benson 

 of Gambier is the only positive breeding record of this state of which I am 

 aware. 



The Savanna Sparrow is found during migrations along the bushy banks 

 of streams, in weedy fields and bottom-land meadows, together with their 

 interrupting fence-rows and hedges. In habits and appearance it most nearly 

 resembles the Vesper Sparrow, but may be instantly distinguished by the con- 

 spicuous way in which it "parts its hair". Like the other bird, it pitches 

 suddenly off its perch when disturbed and flies rapidly above the surface of the 

 ground, following every inequality with bewildering precision. Its song is 

 described as a "curious, squeaky affair", as inconspicuous as the bird.
