 Mar.,1915 A FORTY ACRE BIRD CENSUS AT SACATON, ARIZONA 87 of the school acreage, and one in the northwest ten acres. One of the nests was out in the open near the irrigating ditch, and had no shelter whatever. It was on the gentle slope of a small depression, and children passed near it every day on their way to school. April 7 it had seven eggs in it, and the bird continued to deposit them till May 6, when the eighteenth was in the nest. When I found the nest I was' afraid the hot sun would cook the eggs, so threw down a plank in a careless manner nearby. I moved it a little nearer each day until it shaded the eggs most of the time, the old bird apparently paying no attention to the intrusion, as she kept on with the work of filling the nest with eggs. Soon after the set was complete she left the nest, or was caught or killed, as the eggs remained uncared for until May 31, when I took them. It vas a jobto blow them, as long exposure to the sun had hardened and dried the contents of many. Two nests were in the school woodpile, containing nineteen and thirteen eggs, respectively. Another, in a pile of short boards and kindling about ten feet from the school woodshed, had seven eggs in it. The nest out in the fields had nine eggs, and was at the base of a Lycium bush. About the middle of June I put some straw in an old nail keg, open at one end, and placed it on its side in the forks of a mesquite tree about two feet from the ground. The mesquite had some saplings starting from the trunk that sheltered the keg. June 24 I found that a quail had moved in and had laid two eggs. Later she completed the set, only eight eggs, and successfully hatched all but one. She was quite tame on the nest, and would not be scared off by any mild measures. I tried hammering on the rear of the keg, rolling it gently and talking to her, requesting her to get off and let me count the eggs, but unless I put in my hand at the front of the keg she sat pat. Zenaidura macroura marginella. Western Mourning Dove. Eleven Mourning Dore's nests were found in the limits of the forty acres. Eight were in mesquites, two in Zizyphus and one in a catsclaw bush. The average height was seven feet. The latest date was July 23, when two nests were found, one with fresh eggs, the other with eggs about half incubated. Melopelia asiatica trudeaui. White-winged Dove. One nest with young was found, and this a few feet outside the limits of the forty acres, though many of the birds fed over the tract. The absence of large mesquite trees was the reason for.the lack of nests, as these birds seem to prefer to build higher up in the trees than do the Ffouruing Doves. Both species frequent the school yard, the Mourning Doves to eat the weed and flower seeds, particularly those of the California poppy, and the White-wings to eat the watermelon I put in the back yard for them. Scardafella inca. Inca Dove. A brood was raised in a mesquite tree not far from the house, and a second set lald in the same nest June 21. A few days later the eggs disappeared. These little birds frequent houses and yards, but seem slow to come around a new establishment. The house here has been built three years, this being the fourth summer, and the birds have just adopted it. Last summer a pai r came and looked it over, staying a few days, and this year they settled here. Geococcyx californianus. Roadrunner. A nest with four young nearly grown was found on June 7, in a mesquite about five feet from the ground. When I looked into it tw6 of the birds jumped from the nest, and would not stay when put back. The others remained, as they were smaller. Another
