complete set of eggs. My Berwyn dates for arrival 

 and departure: 



May 3 (1896) — May 26 (1900); ave. 10 yrs. 

 May 17. 



Aug. 29 (1896) — Oct. 5 (1895); ave. 10 yrs. 

 Sept. 14. 



98. Coccyzus erythrophthalmus Black - billed 

 Cuckoo, "kow bird," "rain bird," "rain crow." 

 Not common summer resident. Arrival, May 9 

 (1915) — May 25 (1908); ave. 5 yrs. May 19; 

 departure, Sept. 22 (1906). I have found nests 

 •with, incubated eggs on June 15, 1885: Aug. 6, 

 1886; July 15 and 28, 1887. 



99. Ceryle alcyon Belted Kingfisher, "kingfisher," 

 "rattler." Not common summer resident; resident 

 in open winters. In point of numbers, this is one 

 of our scarcest birds though always conspicuous. In- 

 deed it is possible for a single individual in the 

 course of a year or two, to practically exterminate 

 it over a considerable area; a demonstration of this 

 occurred near Berwyn a few years since, in the 

 interest of a trout pond. 



100. Dryobates villosus villosus Hairy Wood- 

 pecker, "sapsucker." Tolerable common resident, 

 somewhat local in distribution. Montgomery and 

 Sharpies found it only as a winter visitant. Phil- 

 lips took a set of eggs in Kennett Twp. Apr. 20, 

 1868 (F. and S., vi, 57) ; I have found it breeding 

 in Tredyffrin Twp. on several occasions, and it is 

 also reported nesting in Willistown (Hall, Orn. 

 and Ool., ix, 137) ; Oxford (Burn MS.), and the 

 Welsh mountain region (Hunt MS.).
