84 1935 Mar. 1. I watched ducks at Lake Minnet for half an hour in the afternoon, 3:15 to 4:15. Many of the diving ducks were asleep out from the embarcaderos but I began to notice flapping noises as 3:30 approached. First one, then another would flap its wings violently, part of the time in the water, then rising as high as possible and flapping vigorously. Later near the fresh water feeding place, there was much vigorous bathing and preening. Mallards were mating. Copulation took place with the female almost under water. Males were quacking -- a very subdued noise as contrasted with the quack of the female. Did not see the European Widgeon. Blue Snow Goose was small and had no black on the edge of the mandible. Its note was very different from the larger Snow Goose. All the ducks and geese seemed excitable and made much more noise than on other days when I have been there. Eared Grebes were numerous. Saw no Goldeneyes, Buffle Heads, Spoonbills or Teal but did not have my binoculars so could not see the birds at a distance. Mar. 3. Boulder. Arrived at 5:40 p.m. Water Angel was singing a little up stream from the college -- continued for ten minutes. Frost at night. Mar. 4. Large flocks of Pine Gisteris. Two Chickadeers were feeding and calling near the box we put up last summer. I did not see whether they entered it. Kingfishers were heard frequently down stream. A Sharp-shinned Hawk dashed into a bush; a Brown Towhee gave its alarm note as it flew out. Saw no quail or rabbits on the place. Much warmer at night. A touch of frost east of home.
