The Black Hagdon of the fishermen — represented by the upper 

 figure of the illustration on page 272 — is a common bird on the 

 North Atlantic between Newfoundland and the Carolinas during 

 the autumn and winter months, though it appears to have escaped 

 the notice of Nuttall and his contemporaries. 



This bird is not known to breed on our shores, nor has any 

 breeding-place of the species been discovered, though it is very 

 probable that its nesting habits are similar to those of the Pacific 

 form, P. griseus, which our bird very closely resembles in appear- 

 ance, and with which it may be identical, as it is considered by 

 some British authorities. 



Nests of griseus discovered in the South Pacific were placed at 

 the end of a burrow, which ran horizontally three or four feet, and 

 then turned to the right or left. The single egg, which was placed 

 on a rude cushion made of twigs and leaves, was of white color, 

 and measured on the average about 2.60 X 1.70.

 hama Islands and southward, and is seen off the shores of the 

 mainland, occasionally wandering as far north as Long Island. It
