Rare in Europe; one or two specimens have, however, been killed 
in the British Isles. North America is its true habitat, over the 
whole of which it appears to be found during winter. As spring 
approaches the greater portion of them retire to the north, though 
some remain and breed in Pennsylvania, Kentucky, and the inter- 
mediate district. It builds in holes of trees and rocks where it can 
find them; but in districts devoid of such localities, builds on the 
ground on the borders of lakes, laying from six to ten white eggs. _

Both male and female similar to M. merganser, but very much 
smaller. Both my specimens are in adult plumage, therefore the 
great difference in size is not accounted for by their being young birds.
