158 1937 Oct.4. Wildcat Canyon: Fletcher group. We followed the bottom of the canyon above the reservoir. A Traill Flycatcher was seen and watched closely for about 15 minutes. No median line, yellowish under the tail. We could not distinguish any eye-ring but it was much too light underneath for a Wood Beecher. Gambel, Golden-crowned and Purple-brown Sparrows were seen; three Sh. Sh. Hawks circling about when a flicker pounced in a dead oak flew out at them. This happened several times then the hawks rose in small circles above the hills and disappeared. Very few songs: Vigor's Wren, Wren-Tit and a few white- crowns, one soft sweet-set call from titmouse. Winter aggregations already in evidence. On the way home I saw a R.c. Kitelet in the Strettion's garden. Beautiful weather after first rain. Oct.5, Audubon Warblers were calling near our house. Oct.6. Heavy fog but lasting only a few minutes above the stadium (6:30-7:15a.m.) then light with breeze. Oct.7-10- Hot, dry winds. Oct.11- Wildcat Canyon- A large flock of Willow Goldfinch at Spence St. Reservoir in grey winter plumage. Dr. Griniell tells me they moult (body) twice a year while Gld. Goldfinches moult only once and with bright plumage in fall. Many flocks of Browned Sparrows; everywhere Ducks. On the Campus I saw a small flock (10?) of Cedar Waxwings. Coster. Oct.12 a.m. A House Wren heard off Wallows.
