1869. Doubtless the subspecies subvirgatus occurs in migra- 

 tions, but records are not available. 



Note: Ammodramus maritimus (Wils.). SEASIDE SPARROW. 



The statement of Dr. Elliot Coues in his "Birds of New England" 

 (Proc. Essex Inst., Vol. V, p. 282) that this species occurred at Rye 

 Beach, was an error, the Sharp-tailed Sparrow having been the bird in- 

 tended (Brewster, '7yb). 



176. Zonotrichia leucopkrys (Forst.). WHITE- 

 CROWNED SPARROW. 



A spring and fall migrant, uncommon in the lower parts of 

 the state, but seemingly more plentiful in the higher country. 

 More birds are seen also in fall than in spring. Mr. Bradford 

 Torrey and Mr. H. W. Wright have found the bird regularly 

 among the White Mountains from September 25 into October, 

 and Mr. G. H. Thayer reports it as sometimes common at Mo- 

 nadnock in Migrations. I have observed it on one occasion on 

 the Saco meadows at Intervale so early as September 21, 1900. 

 During the spring of 1900 this species was seen at many locali- 

 ties in unusual numbers, and Mrs. E. E. Webster informs me 

 that at Franklin Falls it seemed more plentiful than the White- 

 throated species during May of that year. 

 Dates : May 6 to 25 ; September 21 to October n. 



177. Zonotrichia albicollis (Gmel.). WHITE-THROAT- 

 ED SPARROW. 



A common spring and fall migrant, and as a summer resident, 

 common throughout the Canadian portions of the state and even 

 up into the sub-alpine zone on the White Mountains. South 

 of Lake Winnepesaukee, it breeds on Mt. Monadnock and the 

 surrounding hills, on South Kearsarge, and elsewhere locally 

 along the higher land in the western part of the state. Among 

 the foot hills of the White Mountains, scattering pairs breed 

 even at low elevations in the valleys in bushy open spots, but it 

 is not very common until the deeper sub-Canadian woods are 

 reached. On the mountains it is common up to the limit of 

 scrub growth at 4,800 to 5,000 feet, and a few push still higher 

 up to avail themselves of outlying clumps of stunted growth. I
