222 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



169 [387] Coccyzus americanus (Linn). 

 Yellow-billed Cuckoo. 



Not uncommon irregular and local summer resident ; May 10 to September. 



Eggs : May 20 to June 30. 



The Yellow-billed Cuckoo is largely a bird of the Upper Austral zone, but 

 breeds in Esse.x County, chiefly in the southern part. Thus I have records for 

 Lynn, Swampscott, Beverly, Lynnfield, Andover, and also, but rarely, Ipswich. 

 It appears to vary irregularly in numbers, being more common in some years 

 than in others. 



170 [388] Coccyzus erythrophthalmus (Wils.). 

 Black-billed Cuckoo. 



Common summer resident ; May 10 to September 25 (October 21). 

 Eggs : May 30 to June 17. 



This Cuckoo generally departs in September, but I saw one at Ipswich as 

 late as October 21st, in 1900. 



Although I have several times seen Cuckoos chased with great wrath by 

 Robins, I have never found their eggs in Robins' nests, where they are said 

 occasionally to lay them after the manner of the European Cuckoo. 



The nocturnal habits of flight and song in the Black-billed Cuckoo may 

 account for the fact that one was killed by striking one of Thatcher's Island 

 Lights at 1 1 p. M., on June loth, 1903. I have heard it calling at night. 



171 [39°] Ceryle alcyon (Linn.). 

 Belted Kingfisher. 



Common summer resident ; (winter) ; April 7 to October (December 29, 

 January 31). 



Eggs : May 17 to June 6.
