Quast 1948 Journal 124 June 17 Pozo Grande, 25°46'N, 112°02'W, Baja California strong breeze from the west. While feeding in the manner they made excellent targets and I obtained five and Dr. Benon eight. At 7 PM many Purple Martins and Violet-green Swallows were feeding above the pond in what almost it appeared to be a cloud of birds. They disappeared just at late dusk 7:30 and the bats appeared. At sundown many Nightlows were seen, some flying very close to us and drinking from the pond while in flight. Despite their flying within five feet of us no sound of air in their feathers was heard. At dark about ten ducks flew over the pond and attempted to alight but were frightened by our presence. We were disappointed to find that very few Myotis yumanensis were to be seen around the pond. Last time we were here they were very plentiful, feeding in a large group low over the water and among surrounding bushes, but this time only four or five seen and only one netted (by Tevis). White-winged doves and Mourning doves were also common before dark.
