172. Animodramus saiidwicheiisis savanna 



(Wils.) SAVANNA SPARROW. 



A common summer resident, especially of the broad Transi- 

 tion valleys, where it frequents the meadows with the Bobo- 

 links. Occasional pairs follow the cleared land well up onto the 

 hillsides, where, as at Jackson, among the White Mountains, 

 I have observed them up to 1,600 feet or so. Mr. G. H. Thayer 

 also reports that a few breed at Dublin, on a high, grassy, pas- 

 ture hill, at i, 600 feet. On July yth, 1898, and on the follow- 

 ing day, while on a trip over the Presidential range, I observed 

 a single Savanna Sparrow singing, as if quite at home, from a 

 rock on the northeast side of the summit of Mt. Washington, 

 but a few yards from the buildings, and it is not impossible that 

 a pair was breeding there among the sedges. 



Dates : April 20 to October. 



173. Aminodramus savaimarum passeriiius 



(Wils.). GRASSHOPPER SPARROW. 



A rare summer resident in certain localities among the Tran- 

 sition valleys of southern New Hampshire. A few follow the 

 Connecticut valley meadows up so far at least as Walpole, 

 where Mr. R. Hoffmann observed a single bird in 1899, and an- 

 other in 1900. Others push up the Merrimack valley, apparent- 

 ly with some regularity. Dr. W. H. Fox writes me of one not- 

 ed at Hollis on May 13, 1876. Mr. C. F. Goodhue ('77a, 49) 

 has recorded its occurrence in summer at Webster ; Mr. Ned 

 Dearborn ('98, p. 25) also states that he has usually found one 

 or two each season in the neighborhood of Tilton, still farther 

 up the valley. Beyond Lake Winnepesaukee the bird seems 

 not to occur. 



Dates : May 13 to Summer. 



174. Animodramvis henslowii (Aud.). HENSLOW'S 

 SPARROW. 



A local summer resident, breeding in small numbers in cool, 

 open swamps of the Transition area grown up to sedges, grass- 

 es, small bushes and the rank hellebore. Apparently this bird 

 is a species characteristic of these peculiar ''islands" of the
