1943 Jan. 17. Heavy white frost in morning after a clear night. Air sharp all day in spite of clear sunshine. In the afternoon 2:45 p.m. J.T. and I walked up Panor- amic to stile and then south on road toward the rocks above the end of Dwight Way. Lying one or two spots shelters from the cold breeze. Several Vireos and thrushes in the brush at the top and I heard one quailcatcher. Redtail only heard seen. Jan. 18. Still colder. Clear. Heard a Rufous-crowned Sparrow up hill from the Panoramic Switch- backs. Warbler only song heard. Jan. 19. North wind ended. Chilly, overcast.

Towhee 3t, Brown Towhee 2t, Fox Sparrow 1+ and all Several of the N. Thrushes, Robins and Lunettes and Purple Finches were at the mouth of Hamilton Canyon where a pyracantha furnished berries in Darby's garden and Toyons below the acacias still have berries. G.c. Sparrows were seen in a brush pile below the road and also eating jayn berries. The hawk was perched on the electric pole near the usual perch of Anna H. but the latter was not seen. After the hawk left I heard the hummer down hill, whistled once. Crows willows out. Acacia and Eucalyptus in bloom. Below the switch- back many birds were scratching - 3p.T. & Fox Sp.
