138 Harlow, Breeding Birds of Penna. and N. J. [ April 



though sometimes locally throughout both states. Data on fifty-three nests 

 give: average set, 5 (3-6); average date, July 26 (July 10-September 3). 



90. Spinus pinus. Pine Siskin. — The same remarks apply to this 

 species as to the Crossbill. During the spring of 1917 they remained until 

 May 15 in Center County and until June 8 in Wayne but showed no inten- 

 tion of breeding. A large number did nest in Warren County, however, 

 in 1912, and a set of three eggs taken there on April 30, 1912, is in my col- 

 lection. 



91. Pooecetes gramineus gramineus. Vesper Sparrow. — Very- 

 common, breeding throughout. Data on twenty-six nests give: average 

 set, 4 (3-5); average date, May 8 (May 2-June 13). 



92. Passerculus sandwichensis savanna. Savannah Sparrow. — 

 I have failed to find this bird breeding in southern New Jersey. In Penn- 

 sylvania it breeds most commonly in Warren County so far as my experi- 

 ence is concerned; regularly but rather uncommonly in Center County, 

 and rarely in Pike and Wayne. These remarks are based mainly upon 

 the presence of the birds in summer as I have found but two nests: 1, State 

 College, Center Co., Pa., July 20, 1911, two eggs; 2, Warren, Warren Co., 

 Pa., May 19, 1912, four eggs. 



93. Ammodramus savannarum australis. Grasshopper Spar- 

 row. — Locally common in both states but becoming rare in the northern 

 mountainous counties of Pennsylvania. I noted it in summer for the first 

 time in Wayne and Pike Counties in 1917, one pair in each. Data on ten 

 nests give: average set, 4 or 5 (rarely 3); average date, May 28 (May 22- 

 August 4). 



94. Passerherbulus henslowi henslowi. Henslow's Sparrow. — 

 Breeds regularly and fairly commonly in Ocean, Burlington, Atlantic and 

 Cape May Counties, New Jersey. In 1913 I discovered a small colony, 

 in Huntington County, Pennsylvania, my only breeding record for the state. 

 Data on nine nests from New Jersey and three from Pennsylvania give: 

 average set, 4 (rarely 5); average date, June 4 (May 26-July 16). 



95. Passerherbulus caudacutus caudacutus. Sharp-tailed Spar- 

 row. — Breeds commonly on the coast marshes of New Jersey where I 

 have found it much more plentiful than the Seaside Sparrow, especially 

 from Atlantic to Ocean County. Data on forty-five nests give: average 

 set, 4 (sometimes 5); average date, June 4 (May 26-July 12). 



96. Passerherbulus maritimus maritimus. Seaside Sparrow. — 

 Common breeder on the New Jersey coast marshes, being more abundant 

 in Cape May County than elsewhere. Data on nine nests give: average 

 set, 4 (3-5); average date, June 2 (May 30-July 5). 



97. Chondestes grammacus grammacus. Lark Sparrow. — I 

 saw a pair of these birds on May 11, 1914, evidently breeding, near Alle- 

 ghany, Pa. 



98. Zonotrichia albicollis. White-throated Sparrow. — I have 

 noticed this bird as a fairly common summer resident at Pocono Lake, 

 Monroe County, Pa., and nests have been found there by others.
