 .[an., 1912 BIRDS OF A MOHAVE DESERT OASIS 35 Ixobrychus exilis. Least Bittern. One caught August 7 in the oily pond near the railroad shops, its wings covered with crude oil. Ardea herodias herodias. Great Blue Heron. One could be seen on nearly every trip to the water hole throughout the year. Herodias egretta. Egret. A flock of three stopped for a few minutes May 2 at the small oily pond near the railroad shops. One, shot by an engineer and given to me, is now in the collection of Mr. A. B. Howell of Pasadena. Butorides virescens anthonyi. Anthony Green Heron. A few seen at the water hole during August and September and not again till April 5. llycticorax nycticorax naevius. Black-crowned Night Heron. Several were seen during August and September, after which they left to re-appear April 5. Even in the town three or four would occasionally roost in the very small cotton- wood trees, a few feet from dwellings. Grus mexicana. Sandhill Crane. Four were seen in a small grain;field Feb- ruary 28. They only stayed one day. A flock of twelve flew overhead March 17 and three April 5. I spent nearly an hour stalking these four birds and was within a few feet of shot gun range when they flew away alarmed by a horse with a bell on its neck running out of the brush. From their large sizet took them to be Urus rnexicana, rather than the smaller . canadensis. Porzana carolina. Sora. Resident; seen occasionally through the year. Fulica americana. Coot. Seven or eight always in evidence at the water hole, while at times as many as fifty were present. Breeds. Lobipes 1obatus. Northern Phalarope. Seen only between August 20 and Sep- tember 10 when they were plentiful. Three secured August 28. Steganopus tricolor. Wilson Phalarope. A lone individual seen swimming at the margin of the pond, June 10. Recurvirostra americana. Avocet. Four stayed at the pond during the inter- val between August 20 and 28. Himantopus mexicanus. Black-necked Stilt. About a dozen stayed along with the Avocets. A lone bird was seen April 10. Gallinago delicata. Wilson Snipe. First seen October 22, and then commonly up to, and through, April. Macrorhamphus griseus scolopaceus. Long-billed Dowitcher. One seen and secured February 24. Pisobia minutilla. Least Sandpiper. Several observed in August; none seen again till February 28, when they became fairly numerous. Totanus melanoleucus. Greater Yellow-legs. Nine birds were seen, one each on October 19, February 21 and February 23, a pair March 20, three on April 5 and one on April 21. Actiris macularius. Spotted Sandpiper. Seen August 5 and October 11. After April 16 a dozen or more could be seen about the water hole every day. 0xyechus vociferus. Killdeer. Abundant resident, and I might say a great nuisance when hunting other birds. Lophortyx gambeH. Gambel Quail. Abundant resident. Very hard to secure, as their favorite haunts are the thick mesquites. Zenaidura macroura caroHnensis. Mourning Dove. Abundant everyv)here during August and September. After September they left and were not seen again till December 9, when a pair would be seen rarely around the water hole. After May 1 they became abundant again. Cathartes aura septentrionalis. Turkey Vulture. Occasionally seen circling around up to October 1. After that none were seen again till March 20.
