fig THE BIRDS OF MONTREAL. 



of this species have been shot on the Island of 

 Montreal (Dunlop, Craig). I am not aware of any 

 occurring here in recent years. 



127. Black-billed Cuckoo. (Rain-crow.) C. ery- 

 throphthalmus (Wils.) 



" Summer Resident/' common. Breeds in Mount 

 Royal Park. I have found their nests, containing 

 eggs, from June 4 to July 22. Observed here from 

 May 21 to September 5. Their nests are generally 

 built in thorn-bushes, from one to eight feet above 

 the ground, but small cedar trees are favorite build- 

 ing sites for them as well. This bird appears to 

 have a remarkable habit of laying fresh eggs while 

 those already laid are being incubated and hatched, 

 as the following record of the cuckoos nests found 

 by me will show : 

 July 8, 1883. 3 Eggs. 



" 15, " -1 Youngling. 



16, " -1 Egg. 



22, " 2 Eggs. 

 June 6, 1885. 1 Egg, incubated. 



" 6, 1886. 3 Eggs and 2 (black) younglings ; 

 two of the eggs incubated and 

 one fresh. 



12, " 4 Eggs, 2 incubated and 2 incu- 

 bating. 



12, " 5 Eggs, 1 incubated and 4 incu- 

 bating.
