624 THE DOUBLE- CRESTED CORMORANT. 
There are no recent accounts of the nesting of this bird within the limits 
of the state, but its present occurrence during the breeding season is well 
within the bounds of possibility. Like the Wood Duck, it selects for a nesting 
site a hollow tree or stub in some secluded spot. Dr. Brewer tells of an in- 
stance, in the neighborhood of the St. Croix River, in Maine, where the claims 
of the two birds came into conflict. “Several years ago Mr. Boardman’s 
attention was called to a singular contest between a female Wood Duck and 
a female of the Hooded Merganser for the possession of a hollow tree. The 
two birds had been observed for several days contesting for the nest, neither 
permitting the other to remain in peaceful occupancy. ‘The nest was found 
to contain 18 fresh eggs, of which about a third belonged to the Merganser ; 
and as the nest was lined with her own dark-colored down, it appeared prob- 
able that this bird was the rightful owner of the premises.”
