{Continued from p. 29.) 



74. Otocoris alpestris praticola. Prairie Horned Lark. — An 

 irregularly distributed breeding bird over most of Pennsylvania north of 

 Northampton, Schuylkill, Northumberland, Cumberland and Franklin 

 Counties. I have found it nesting on the Pocono plateau and in Huntington, 

 Center, and Greene Counties. Data on seven nests give: average set, 

 3 (4-5) ; average date, March 25 (March 18) ; a second set, May 20. 



75. Cyanocitta cristata cristata. Blue Jay. — Breeds commonly, 

 though in some places locally, throughout both states. Data on sixteen 

 nests give: average set, 5 (4-6); average date, May 5 (April 29-June 17). 



76. Corvus corax principalis. Northern Raven. — Does not now 

 breed in New Jersey and is nearing extinction in Pennsylvania, making a 

 last stand in the mountains of Snyder, Mifflin, Center, Blair, Clinton, Union, 

 Juniata and Huntington Counties. During 1917 only one pair out of five 

 previously located was present. Nests have seldom been found nearer 

 together than thirty miles, and all have been located on cliffs with one 

 exception, that one being in a pine tree. Data on ten nests give the fol- 

 lowing: average set, 5 (4); average date, March 4 (February 27-April 12). 



77. Corvus brachyrhynchos brachyrhynchos. Crow. — Nests 

 abundantly throughout, even along the sea coast of New Jersey with the 

 Fish Crows. Data recorded on 194 nests give: average set, 5 (3-6); 

 average date April 10 (March 26-May 20). 



78. Corvus ossifragus. Fish Crow. — Nests commonly through 

 southern New Jersey being especially abundant in Cape May County where 

 they breed in colonies as well as singly. In Pennsylvania I have found 

 them nesting in the valleys of the Delaware and Susquehanna as far north 

 as Bucks and Dauphin Counties. Data on thirty-two nests give: average 

 set 5 (4-6); average date, May 14 (April 19-May 24). 



79. Sturnus vulgaris vulgaris. Starling. — Now breeding over 

 practically the entire state of New Jersey and well established in Penn- 

 sylvania as far west as Altoona, Blair County. It reached Wayne and 

 Center Counties and bred there in 1917. Data on eleven nests give: 

 average set 5 (4-6); average date, April 28 (April 20-May 14). 



80. Dolichonyx oryzivorus. Bobolink. — Very locally distributed 

 in Pennsylvania in the breeding season. They Occur regularly as near 

 Philadelphia as Ambler, Montgomery Co. and Newtown, Bucks Co., and 

 I once saw a pair as far south as Tinicum, Delaware Co., where however,
