Page 44 - The individual variation in this species is very great. A large majority have the ordinary white frontal band and the under parts plentifully mottled with black. In others the black gradually decreases until some specimens do not show the least trace of dark on the abdomen; in such instances the frontal white band is usually present. The young exhibit a dark brown frontal band in place of white, but with more or less dark spots on the abdomen.
Page 67 - In June, 1875, I found several pairs of these birds about the Calumet Marshes, where, from their actions, I was certain they were breeding, but was not fortunate enough to find their nests. The 10th of June, 1876, Mr. Rice observed a pair about a prairie slough near Evanston. A fe'w days later a set of four eggs were brought him from a similar situation a few miles north-west of that place, and from the description of the parent bird — driven from the nest — he decided they must belong to this...
Page 75 - Some thirty pairs were breeding along the beach at this place, within a space of two miles, and I afterwards found the birds as numerous at several points along the shore. Every effort was made to discover their nests without success, although the birds were continually circling about or standing at a short distance uttering an occasional note of alarm. The first of July, the year previous, Dr. Velie obtained young but a very few days old, at this same locality, showing that there is considerable...
Page 92 - Rep., 1852.) In December, 1874, while hunting Prairie Chickens in a field a few miles south of Chicago, my friend, Mr. T. Morris, was suddenly attacked with great fury by a pair of these birds, they darting so close that had he been prepared he could easily have touched the first one with his gun. As it arose to renew the attack he fired a charge of number six shot, and brought it down, dead.

The second then darted at him, and so rapidly that he did not fire until it had turned and was soaring up, but so near...
Page 182 - A rare summer resident. I found a pair near Chicago with full grown young the first of July, and Mr. Rice observed a pair feeding unfledged young the last of April, 1874, at Evanston. The excavation containing the nest was in a tree, standing on one of the principal streets of the town.
Page 46 - There is much uncertainty in using the records concerning this species, because it is so commonly confounded with the Snow Goose, which is locally known as Brant all through the West.
