CHARADRIIDJE — THE PLOVERS — ^EG-IALITIS.

mud-flats around the Warm-spring Lake numbers were seen running nimbly and 
swiftly over the ground, all the while uttering a soft, rather musical, whistling note. 
All the specimens procured were in the full breeding-plumage. 
Mr. E. W. Nelson also mentions meeting with this species on the shores of Salt 
Lake, near the mouth of the Liver Jordan. The birds were abundant, and he saw 
the young — only a few days old — the 1st of August. 
The eggs of this species have an average length of 1.18 inches, and a breadth of 
.95. Their ground is a light fawn-colored drab, over which line dottings, lines, 
and irregular markings of a dark bistre are ecpially distributed, except about the 
smaller end, which is nearly free from any mark. These eggs were taken near San 
Francisco by the late Mr. T. Hepburn. The eggs of JE. cantianus, to which this 
species is now regarded as being very closely allied, are of a slightly more oblong 
shape, measuring 1.25 inches in length, and .90 in breadth. They have a yellowish 
stone-colored ground, spotted and streaked with black. 
More recent specimens of the eggs of the nivosa have a ground-color of a pale 
grayish buff, with markings in form of small dots and zigzag pencillings of black, 
and measure 1.25 by .90, and 1.25 by .85 inches.
