Nov., 1916 NESTING OF THE LECONTE THRASHER 221 the one photographed (fig. 53), and may be regarded as being typical of those described by Mr. Gilman. Both nests contained three incubated eggs. The skeleton or framework of the photographed nest is bulky, strong and well anchored anfid the many ramifications of the spiny cactus. The lining is made entirely of a fine, gray, woolly plant which grows in abundance in the locality and is pulled up entire by the bird. This material is firmly pressed to- gether and forms a remarkably felt-like padding about one-half inch in thick- ness. The light gray color of this lining contrasts well with the brown frame- work and the light blue of the eggs. (See fig. 54.) At Cabezon the Pasadena Thrasher (Toxostoma redivivum pasadenense) occurs also. Nests of this bird were found to differ radically from those of the Leconte Thrasher in not having the felt-like lining. Colton, California, August 24, .1916. THE SAN DOMINGO GREBE IN BEXAR COUNTY, TEXAS By ROY W. QUILLIN and RIDLEY HOLLEMAN BOUT TEN miles south of San Antonio, there is a large marshy lake which covers something like a thousand or twelve hundred acres. Being the only body of water of this size in this part of Texas, and having excep- tional surroundings, it is the mecca of the water birds of this county. Practi- cally the entire lake is surrounded by a barrier of cat-tail redds, rules and marsh grass; which in some portions is one hundred or more yards in width. While searching for nests of the American Eared Grebe in a secluded inlet of this lake we located our first nest ?vith eggs of the San Domingo Grebe (Colym- bus dominicus brachypterus). Both cat-tails and tules were growing at this point, but not so thickly as they are generally found. In one of the small patches of open water, which break the monotony of these reed jungles, the nest was anchored. In general appearance the nests examined by us average somewhat smaller than nests of the American Eared Grebe, this being especially true o the hollow in which the eggs are deposited. The nests were composed of decayed reeds of every description, heaped into a cone-shaped mass measuring from four to' six inches in height, and from fourteen to twenty-four inches in diameter at the base, tapering to six or eight inches at the top, and .they were liberally plas- tered with mud, especially. the depression which held the eggs. The area of this depression, the depth of which is about one inch, is determined by the number of eggs in the clutch, as they fit snugly into it. Of five nests located from June 25 to July 9, two contained four eggs and three, three eggs. All these sets were from slight to heavily incubated. The eggs were badly stained, and the majority retained a rich brown cast even after the most vigorous scrubbing. In all cases the eggs were covered by a thin layer of damp, decayed reeds. We were unable to flush the bird from any of these nests, and were able to identify them only by patient and lengthy waiting. These Grebes are very hard to see on this lake, as they keep close to the reeds, and if found a short distance from them they immediately slip under the water and disappear. However,
