70. Phasianus colchicus -\- P. torquatus English 

 Pheasant. Resident. This fine hybrid has become 

 locally established. 



71. Ectopistes migratorius Passenger Pigeon, 

 "wild pigeon." Formerly an irregularly abundant 

 transient, now extinct. John D. Dillen states that 

 his earliest recollections of this species dates back to 

 about 1 864 when a flock was found roosting in Gib- 

 son's pines, a four-acre tract, located on the South 

 Valley hills, Tredyffrin Twp. upon the very spot 

 where "Weadleytown" now stands. The pigeon's 

 stay was always comparatively short, rarely in Au- 

 gust, but could be looked for any time between 

 Sept. 10 and Oct. 10; nevertheless a flock of about 

 300 individuals occurred in early November, 1877 

 or 1878. It was less abundant in spring; a flock 

 of about 50 birds in March, 1867, and another of 

 about 200 in March, 1872 or 1873 (Cass., xiv, 

 33'36) . Pennock states that small flocks were seen 

 at Kennett Square from 1869 to 1873. Dr. H. R. 

 Wharton shot one or two in a wood at Stratford, 

 1878, and there is a specimen in the J. W. Sharp col- 

 lection without data but I understand that it was 

 secured nearby. Dr. Montgomery shot one individ- 

 ual Sept. I, 1886, in Birmingham Twp., and a 

 female in West Goshen Twp., Sept. 9, 1887. Both 

 specimens are in immature plumage and now in the 

 collection of the Academy of Natural Sciences, Phil- 

 adelphia, and are believed to have been the last 

 specimens taken in Southeastern Pennsylvania. A 

 flock of fifteen passed over Berwyn, April 17, 1901
