“THE RED-LEGGED BLACK DUCK. 585 
north to Labrador, breeding southward to the northern parts of the United States.” 
—A.O.U. Now believed to be restricted to the eastern portion of this range. 
Range in Ohio.—Not yet satisfactorily distinguished from that of the fol- 
lowing variety. Probably not uncommon during migrations. If “Black Ducks” 
formerly bred in the northern parts of this state, as Wheaton supposes, they were 
probably of this form. 
THIS form and the next taken together (since their relations are not 
clearly determined) are not nearly so common as the Mallard, which they 
closely resemble in habits. "They are perhaps more common upon the larger 
reservoirs and Lake Erie than elsewhere, altho they do resort to the smaller 
ponds and streams during migrations. 
The “Black Mallard,” as it is called by sportsmen, is more frequently 
seen in pairs and in small companies than in large flocks, indicating that 
we are west of the center of abundance for the species. ‘They are scarcely 
as wary as their gray congeners, and their flesh is fully as excellent. 
It is a rare sight to find a company of these dusky birds, lulled to a 
sense of security and disporting themselves freely upon the water. If it is 
early morning the first to wake are busy “‘tipping’ and dabbling for a 
breakfast of cress and succulent roots, while others shake off the traces of 
recent slumber by rising perpendicularly in the water and flashing the pure 
white of their under wing surfaces in the morning sun. 
Meals are hurried and energetic for most, since they must needs pass 
further north to breed, but it is pretty certain that some do nest in the north- 
ern part of the state. At least I do not know how otherwise to interpret the 
appearance of certain able-bodied pairs in late May and early August, or to 
account for a flock of fourteen seen August 6th, *1tg01, upon Middle Bass 
Island. 
The nest, when found, may be easily recognized even in the absence of 
the parent, from the blackish feathers which enter into the lining, more or 
less abundant according to the stage of incubation reached.
