Although we searched the patch of sedge carefully we were not able to locate any of the young. Another brood of downy young was reported to us. All of the evidence obtained points to the conclusion that, even so early as the middle of lV[ay, many 1Viallards were already through nest- ing. The downy young are much like those of the Cinnamon Teal, but can b? distinguished by the presence of more yellow on the sides of the head and by the broader bill. Dafila acuta. Pintail. Four nests of the Pintail were examined. One found on a small islet had been destroyed by some animal, for the broken egg shells were found scattered about. Another nest found had been trampled by cattle. On lV[ay 22 a Pintail was seen to flush from her nest as an automobile passed by. The nest was situated about twenty yards from the nearest water and but forty feet from the main county road. It was but poorly concealed, being surrounded by salt grass only about six inches high. The nest, contain- Fig. 63. DowNY YOUNG OF PINTAIL (DaSi?a acura); Los BANOS, MAY 21, 1914. ing seven fresh eggs, was constructed of short grass stems and sparsely lined with dark-colored down. On returning to this nest on the morning of the 24th we found that some animal had been there before us. Only four whole eggs remained, while broken and empty shells were scattered about (see fig. 70). The fourth nest was reported to us as containing eight fresh eggs on 'May 23, and as being located in salt grass within fifty feet of the margin of a large pond. In all, three broods of the Pintail were found in this locality. The first br6od was discovered along with the mother in some shallow water near a tale- grown slough. The downy young all at once started for the shelter of the tales, while the mother flopped into the water not more than ten feet away from me and did her best to lead me in another direction. The brood num- bered seven or eight individuals about nine inches long though there was con- siderable variation in size. On lV[ay 21 a Pintail with ten downy young was discovered on the bank of a pond. When first disturbed she was brooding her young on dry ground about ten feet from the water. The moment she flew the downy young assumed rigidly the same poses they had variously held be-
