This afternoon I was within 8 feet of a partly albino ♂. I saw him hiding on the levee of the main ditch about 100 yards north of the picnic ground. His back was a silvery gray, as was also his tail feathers. When I got that close to him, he flushed so that I wasn't able to see any more detail than that. March 19 Today Dr. Leopold brought 30 members of his Wildlife Management class up to the ranch for a sex ratio pheasant census. We ran the census through rice stubble, along tule-filled ditches, through old star tistle patches, and open ground. The results were as follows: 1) ♂, 28 ♀, 1 unknown; 2) 9 ♂, 39 ♀; 3) 12 ♂, 69 ♀, 1 unknown. This comes to a total of 22 ♂, 136 ♀, 2 unknown, or a ratio of 16 ♂ to 100 ♀. May 16 a hen with 5 young was seen this afternoon. The young were able to fly a short distance.
