Range. - North America west of the Mississippi, breeding from Texas to Manitoba and winter-ing along the Pacific Coast of the United States and from Texas southward.

Eared Grebes differ from the preceding in haying the entire neck blackish. They nest very abundantly throughout the west, in favorable localities, from Texas to Minnesota and Dakota. Their nests are constructed in the same manner as the preceding varieties and are located in similar localities. As do all the Grebes when leaving the nest, they cover the eggs with the damp rushes from around the base of the nest. This is probably for the purpose of assisting incubation during their absence, by the action "of the sun's rays on the wet mass. As they are nearly always thus covered upon the approach of anyone, this may be done also as a protection from discovery. They lay from three to eight bluish white eggs with the usual chalky and discolored appearance. The breeding season is at its height early in June, or earlier, in the southern portion of its range. Size 1.75 x 1.20. Data. - Artesian, S. Dakota, June 21, 1899. Nest of rushes, floating in three feet of water. Collector, F. A. Patton. 13
