Mayhew 1949 Mallard 16. July 9 Conaway Ranch, 2 miles east of Woodland, Yolo Co., Calif. it is located in the SE corner of section 19. July 10 The ♀ could be seen still on the nest. The (23) cattle have trampled everything around the nest pretty badly, but so far have failed to hurt the nest. July 12 The ♀ flushed from the nest at my (25) approach. There are only 2 eggs left in the nest, but I can find no trace of the remains of the others, so I have no idea what has happened to them. These 2 eggs appear to be near the hatching point. Although cattle have been in this field since June 25th they haven't damaged the nest yet. (23) The ♀ flushed from the nest at my approach. 6 eggs are in the nest yet, but the other 2 have completely disappeared without leaving a trace. July 16 The ♀ was flushed from her nest on (33) the rice levee this morning. The nest still contains 9 eggs. (23) The cattle have eaten or trampled all the cover around the nest. One egg has been broken. The ♀ has apparently deserted, since the eggs are extremely hot. July 17 a ♀ + 10 youngsters over 6 weeks old (9) (they were as large as the ♀, but still couldn't quite fly) were seen crossing
