The Red-heads arrive in Illinois from the south in March, and 

 continue northward to their breeding grounds, which extend 

 from Wisconsin, Michigan, and others of the "northern tier" of 

 States, to the Fur Countries. They return in October. 



Where it can obtain the same food, the Red-head is quite as 

 good eating as the celebrated Canvas-back {A. valUsiieria) , 

 though it never commands so high a price in the markets. In 

 short, it is more the costly character of the latter, together 

 with its high reputation, than any real superiority of its flesh, 

 that creates the greater demand for it. 



The Red-head was found nesting on the St. Clair flats, Michi- 

 gan, by Mr. W. H. Collins, who thus describes some of its 

 breeding habits:^ 



"The past season I had the good fortune to find two nests 

 of the Red-head Duck {Aythya americmut), containing respec- 

 tively seven and eight eggs. The first was placed on some 

 drifted rushes on a sunken log, and was composed of flags and 

 rushes evidently taken from the pile of drift upon the log, as 

 they were short pieces, so short, in fact, that the nest when 

 lifted with the hands fell in i^ieces. The nest was about four 

 inches deep, and lined with down from the female. This nest 

 contained seven fresh eggs of a creamy color, and [.s/o] varied in 

 measurements from 2.30X1.75 to 2.22X1.G6 inches, and were 

 of a uniform oval shape, \Qvy little smaller at one end. Tlie 

 other nest was built similar to a Coot's nest, that is, of flags 

 and grass interwoven at the base of a bunch of flags, growing 

 in water three or four feet deep. It was built in such a waj- 

 tliat the nest would rise and fall with the water. This nest also 

 contained down and eight fresh eggs, uniform in size, shape, and 

 color with the others. The birds, male and female, were flying 

 around, and often came quite close to me. The cry of tlie
