The Black Hagdoii of the fishermen — represented by the upper 
figure of the illustration on page 272 — is a common bird on the 
Norlh 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.-
