40. Haliaeetus leucocephalus leucocephalus. Bald Eagle. — 

 Almost if not quite extinct as a breeding bird in New Jersey, though 

 formerly nesting regularly in Salem, Cumberland, Cape May, and Burling- 

 ton Counties. In Pennsylvania I know of an occupied nest in Erie County 

 and a pair may still nest along the Susquehanna, in Lancaster County, 

 though the former well known eyries of that locality have not been occupied 

 during the last two years. Probably a pair or two breed in the wild lake 

 region of Pike, Wayne and Monroe Counties, where I still see them fre- 

 quently. I have known of Eagles nesting at the following places in Penn- 

 sylvania in the last ten years, all of which are now deserted owing to the 

 birds having been shot, or the nest trees falling down, viz: Washington 

 Boro and Peach Bottom, Lancaster Co., Milford, Pike Co., and Towanda 

 Bradford Co. Data on three nests follow: 1. Towanda, Bradford Co., 

 Pa., Feb. 28, 1914; two eggs. 2. Washington Boro, Lancaster Co., Pa., 

 March 2, 1915; two eggs. 3. Erie Co., Pa., May 15, 1915; two large 

 young. 



41. Falco peregrinus anatum. Duck Hawk. — This magnificent 

 falcon still breeds at a number of places in Pennsylvania. I have known 

 of eight pairs nesting in the state within the past five years — along the 

 Delaware from the Nockamixon cliffs to Monroe County and along the 

 Susquehanna from Lancaster to Bradford Counties, as well as rear the 

 cities of Williamsport and Scranton. Data on seven nests give: average 

 set, 4 (3-5) ; average date, April 15 (April 8-April 29). 



42. Falco sparverius sparverius. Sparrow Hawk. — Breeds 

 throughout New Jersey though not commonly in the southern counties 

 or near the coast. Very common in the southern half of Pennsylvania 

 becoming much scarcer in the northern and wilder mountainous sections. 

 It is a rare breeder on the Pocono plateau, in my experience. Data on 

 thirty-six nests give: average set, 5 (3-6); average date April 28 (April 

 13- June 4). 



43. Pandion haliaetus carolinensis. Osprey. — Nests commonly 

 along the New Jersey coast, being most plentiful in Cape May and Cumber- 

 land Counties and nesting up the Bay shore as far as Salem County. In 

 Pennsylvania it is a rare breeder on the lakes of the northeastern counties 

 and at Foxburg, Clarion County. Data on seventy-five nests give : .average 

 set, 3 (2-4); average date, May 20 (May 7- June 10). 



44. Aluco pratincola. Barn Owl. — I have found the Barn Owl 

 only in southeastern Pennsylvania — in Delaware, Chester, Montgomery 

 and Cumberland Counties. Data on eight nests give: average set, 6 or 7 

 (4-8); average date, April 1 (February 28- June 8). 



45. Asio wilsonianus. Long-eared Owl. — This owl in my experi- 

 ence is a very rare breeder in both states. I have only one record, a set of 

 three eggs found in Berks County, Pa. 



46. Asio flammeus. Short-eared Owl. — A very rare summer 

 resident on the salt marshes of the New Jersey coast, where I have seen 

 them and found their pellets in the summer months in Ocean and Burling-
