Sept,. 1908 SUMMER BIRDS OF THE TULARE LAKE REGION 201 and western shores of Tulare Lake from east of the mouth of Kings River to the mouth of Kern River, along Buena Vista Slough and at Buena Vista Lake. Special attention was given to breeding water birds, but the land species were not entirely neglected. Successive years of drought had been followed by two very wet seasons, and at the time of my visit Tulare Lake was higher than for many years. The lake waters in spreading had moistened or partially submerged thousands of acres of land on which a rank new growth of tules and coarse grasses was springing up, affording unusually favorable breeding grounds for birds. Yet few species were nesting in abundance. In the vicinity of Summit Lake local conditions seemed suitable, but water birds were surprisingly scarce. This lake was a place of unexpected natural beauty, its floating peat islands and gracefully overhanging banks of bright green foliage contrasting strongly with the summer aridity of the neighboring San Joaquin plains. The specimens obtained are in the Biological Survey Collection, and have been identified by Mr. H. C. Oberholser. The nestihg of the Green-winged Teal (?Tettion carolinerise) in California has been already noticed. a Among other birds in the following list whose known breeding ranges were nmterially extended are Toxostoma lecontei, and Amphispiza nez,adensis canes- ce?l$. ?Echmophorus occidentalis. Western Grebe. Several were seen in Tulare Lake, near the mouth of Kings River, June 18-23. Podilymbus podiceps. Pied-billed Grebe. Common along the shores of Tulare Lake; noted in Summit Lake, Buena Vista Lake, and in numerous sloughs. A number of nests were found floating in water about two feet deep, among thin tules near the mouth of Kings River, June 18-24; some contained hatching eggs and others had been already abandoned. Sterna forsteri. Forster Tern. Common in flocks near the mouth of Kings River, at the north end of Tulare Lake, June 18-24. Two specimens procured were not breeding. l?ydrochelidon nigra surinamensis. Black Tern. A few solitary birds were seen at various points along the north and west shores of Tulare Lake, June 18 to July 7. A female specimen obtained June 23 was in breeding condition. Phalacrocorax auritus albociliatus. Farallone Cormorant. A large rookery was found in the mouth of Kings River, at the north end of Tulare Lake, June 19. Hundreds of nests in willows, standing in the water, contained young birds most of which were one-half to two-thirds grown. One adult specimen, June 23rd. Pelecanus erythrorhynchos. White Pelican. Large, loose flocks were seen daily while along the north and west shores of Tulare Lake, June 18-24 and July 6-8. Aman who was gathering drifting lumber reported finding a nest contain- ing eggs, on a small island near the west shore, about June 25. Anas platyrhynchos. Mallard. Breeds in small numbers. At the time of my visit the birds were apparently thru nesting. Large-sized young were swim- ming or flying about. Specimens were obtained at Summit Lake, June 26, and on the west side of Tulare Lake, July 7. l?lettion carolinense. Green-winged Teal. A few wdre breeding along the west shore of Tulare Lake, July 7. A brooding bird was shot as she rose from a nest containing seven fresh eggs. Several other females were seen with recently a See CO?)OR, Vol. X, lqo. 3, May-June, x9o8, p. ?29.
