28 HISTORY OF THE 



The birds are said to be common throughout the continent, 

 but I have never been so fortunate as to meet with them often, 

 or in numbers. 



In their food habits, are much like the Franklin's Gull. In 

 their northward flights arrive early, and do not tarry long. At 

 Pewaukee, Wisconsin, where I lived during the early settlement 

 of the State, I noticed nearly every spring a few flocks flying 

 about the lake and alighting upon the melting ice, but I cannot 

 recall seeing them on the lake after the ice was wholly gone. 



The birds are quite noisy, fly gracefully, and float on the sur- 

 face of the water as lightly as an egg shell, and when at rest 

 drift as readily in the breeze. They breed in high latitudes, 

 and in communities; their nests are placed on bushes and trees, 

 usually on the branching limbs of the spruce trees?, and are 

 made of sticks and lined with grasses, leaves, often moss and 

 lichens, with an occasional mixture of down. Eggs usually 

 three, rarely ever four. One set of two eggs, taken July 5th, 

 1864, by Mr. Farlane, on Anderson river, Arctic America, meas- 

 ure: 2.08x1.40, 1.96x1.40. Ground color olive gray, with small 

 spots of varying shades of brown, chiefly clove brown, thickest 

 about larger end; in form, oval to ovate.
