The gadwall, which has been described as a "thoroughbred" looking duck, is the rarest yet mentioned.
In addition we got some grey duck, gadwall, and a number of garganey and pochard.
A month later, however (in May), we obtained nests both of this Pochard and of the gadwall, both built among rushes on dry ground.
The gadwall is really a southern duck, coming into the United States to breed.
gadwall, preferring deep waters, are not numerous in the shallow marisma.
We have seen young gadwall Ducks, and a pair of Geese that had young ones swimming out of our sight.
I saw only one gadwall Duck; these birds are found in abundance on the plains where water and rushes are to be found.
In the autumn the lakes in this neighbourhood are the resort of large packs of wigeon, gadwall and pochard.
