ORNITHOLOGICAL EXPLORATIONS. 



name in time, Heiue's C. telephonus, seems perfectlj' pertinent, as it is 

 based upon a skin from Japan, being " subtns fasciis tenuioribus ac 

 paucioribus quam G. canori fasciatus.". 



The cuckoo is rather numerous in the neighborhood of Petropaul- 

 ski, where in 1882 I heard its well-known note as late as July 11. In 

 1883 it had not arrived when I left the town on the 28th of May. Vis 

 iting the same place again in the middle of September I found that 

 they had already departed. 



I could not detect the slightest difference in the voice or habits from 

 those of the common European form. 



On treeless Bering Island this bird only occasionally makes its 

 appearance during the migrations ; although apparently especially 

 adapted to live among trees, it is by no means absolutely confined to 

 places where such occur, for I have several times found its western re- 

 presentative, during the latter part of June, on the high plateaus of the 

 ^Norwegian mountains above the limit of trees, where it could only 

 deposit its eggs in the nests of the ground-breeding Anthus pratensis 

 and Saxicola oenanthe. 



Three exemplars were shot the year before I visited the island, and 

 ou June 13, 1882, I got a single male, which was shot at Bolschaja 

 JReschka, on the northern shore, while picking up Gammaridce between 

 the bowlders of the beach. The stomach was found crammed with these 

 crustaceans, a rather strange food for a cuckoo ! I had, however, the 

 same experience with a specimen of the next species. 



A native of Germany, who had been residing on Copper Island for 

 about ten years, stated that he had heard the cuckoo's voice there once. 



List of specimens. 



No. 89056.— Iris yellow. Bill horny black ; lower mandible, bluish in the middle, and yellow towards 

 the base ; angle of mouth yellow-, as also the naked ring round the eye ; inside of mouth orange-red. 

 Feet deep yellow.
