1939 Lake Tahoe June 29. We took a picnic lunch to Rubicon Port, where we hoped to find a Townsend Solitaire but were not successful. Mrs. Fletcher, tells us men had been putting out poison for ground squirrels & chipmunks on her place. The boys told me they were using strychnine. In the evening I saw one adult marmot- with eight young as they boiled out from the Humlin's shove. Heard a night hawk. June 30. Returned to Berkeley. Cloudy and cooler when we left Tahoe and cool in valley. July 1. A Grosbeak was singing near the house in the afternoons. Cold, foggy. July 3. We went to Boulder Creek to stay over the Fourth. When we crossed Drum- Barton Bridge we found the usual Avocets - about thirty of them and located three very tiny young ones floating in the salt pool across the road (N. Most of the adults were on the south side - about half way to the bridge proper). Query, Could the babies float just as easily in fresh water?) We also found about 70 Willets (rising at high tide on a mud bank) - About half on the same islet with 20 Avocets, Nothing at the View March. July 4- Boulder Creek. High fog with some car deviation, all day. Balmy. Lois and I took a short walk, especially to locate some Tanagers I heard. We found them in the upper part of the valley north
