26 Harlow, Breeding Birds of Penna. and N. J. [j^ 



ton Counties. I have found but one nest — June 17, 1915, on an island 

 in Barnegat Bay, containing five half fledged young. 



47. Strix varia varia. Barred Owl. — Apparently a regular though 

 scarce breeding bird throughout New Jersey. I have seen them in April 

 or May, in Cape May, Cumberland, Ocean, Atlantic, Burlington and 

 Salem Counties. In Pennsylvania I have found it only in the wilder 

 mountainous sections, from Warren to Pike Counties and south to Frank- 

 lin. I have found only one nest — June 1, 1912, Warren Co., Pa. contain- 

 ing three eggs. This date seems entirely too late to be normal. 



48. Cryptoglaux acadica acadica. Saw-whet Owl. — I have but 

 one summer record for this species, a bird seen in northern Huntington 

 County, Pa., on May 26, 1913, and as this individual was blind in one eye 

 it was possibly not a breeding bird. Young birds have however been taken 

 in the mountains by others, as is well known. 



49. Otus asio asio. Screech Owl. — Very common in both states 

 but becoming much rarer in the mountainous districts and not found at all 

 in the primaeval forests. Data recorded on twenty-one nests give: average 

 set 4 (3-6); average date, April 10 (April 1-May 4). 



50. Bubo virginianus virginianus. Great Horned Owl. — Rare 

 resident in New Jersey confined mainly to the wilder sections. I have found 

 it several times in Salem County during the nesting season. In Penn- 

 sylvania it is generally distributed, everywhere scarce, and becoming exter- 

 minated in all but the wilder sections. Three nests were found at 

 Waynesburg, Green Co., Pa., 1. February 24, 1916, 2 eggs; 2. March 27, 

 1914, three half-fledged young; 3. March 28, 1914, two half-fledged 

 young. Another nest March 12, 1914, at Charter Oak, Huntington Co., 

 Pa., contained two newly hatched young. 



51. Coccyzus americanus americanus. Yellow-billed Cuckoo. 

 — A common breeding bird in the lower ground of both states becoming 

 less plentiful towards the mountains. I have not found it in the boreal 

 parts of Pennsylvania. Data on twenty-four nests give: average set, 

 3 (2-5); average date, June 15 (May 24- August 15). 



52. Coccyzus erythrophthalmus. Black-billed Cuckoo. — Re- 

 places the former species in the northern and mountainous parts of both 

 states, and a rare breeding bird in the southern counties, especially east of 

 the mountains. Data on nine nests give: average set, 3 (2-7); average 

 date June 10 (April 29-June 23). 



53. Ceryle alcyon alcyon. Belted Kingfisher. — Generally dis- 

 tributed throughout both states all the way from the coast of New Jersey 

 to the tops of the Alleghanies, in suitable locations. Data on twenty-eight 

 nests give: average set, 6 or 7 (5-8); average date, May 10 (April 29- 

 June 23). 



54. Dryobates villosus villosus. Hairy Woodpecker. — A regular 

 breeding bird over practically the entire area of both states. Particularly 

 common in Greene County in the southwestern corner of Pennsylvania 

 and on the Pocono plateau. Data on sixteen nests give: average set, 4 

 (3-5); average date, April 25 (April 12-May 14).
