The eggs from New Jersey, attributed to this bird by Mr. Krider, vary in the number and depth of coloring of their markings, the blotches in one being darker and less generally distributed. They measure 2.06 by 1.69 inches. Their ground-color is a yellowish white, intermingled with which are faint markings and blotches of a brownish-purple. Over these are diffused confluent blotches of russet-brown.
An egg from near Wiscasset, taken by Edmund Smith, Esq., the parent of which was secured, measures 2.22 by 1.75 inches, has a white ground, and is marked and blotched with deep umber-brown. These markings are chiefly at one end and only vary in their depth, and are unmixed with any other shading or colors.
