152 HIS TOBY OF THE 



incubation and the rearing of the young to the males. I have 

 never been so fortunate as to find either of the birds upon the 

 nest; but certainly both appear equally watchful and solicitous, 

 circling around and croaking as one approaches their nests, or 

 near their young, (grayish little fellows, that leave the nest as 

 soon as hatched.) In the earliest arrival noticed, the sexes ap- 

 pear to be about equally divided, and I am inclined to think 

 further examination will prove the birds to be joint workers in 

 the hatching and rearing of their young. 



Their nests are placed on the ground, usually on hummocks, 

 quite deeply excavated, and lined with a thin layer of grasses. 

 Eggs three or four, usually four; ground color cream to brown- 

 ish drab, rather thickly but irregularily blotched with varying 

 shades of brown, to black or deep blackish brown; in shape, 

 pyriform. A set of four eggs, taken June 1st, 1883, at Pewau- 

 kee, Wisconsin, from a nest on a marsh, are, in dimensions: 

 1.22X.90, 1.23X.88, 1.23x.88, 1.25x.90.
