Later: found the Traill Flycatcher's nest some 7 feet up in a crotch of slender willow stem in the midst of an isolated willow clump in the meadow - just in process of construction. In a tract of old lodge pole pines a little farther along, a crowd of birds was distraught over something, tho I failed to find what the threatening danger was. The crowd included: Juncos, a pair of Robins, a Lincoln Sparrow, a Pigmy Nuthatch (the first I have seen in the Lassen "section"), a Hammond (or Wright) Flycatcher, several Chipping Sparrows, and a pair of Audubon Warblers. Nearby was a (female) White-headed Woodpecker.

As to mammals: winter earthcores of Thomomys monticola occur in places where the ground is well-drained at the sides of meadows but not out in them. The common chipmunk is Eutamias amoenus, about logs overgrown with snowbushes, but they are very quiet now; two visit camp, but so far are shy. A (female) Eutamias senex was trapped in a neighbor's camp yesterday morning at 5 o'clock. Last evening just before sundown, Dixon shot an old male jack-rabbit (Lepus c. californicus) in a tract of sparse snowbush. Mrs. G. has seen another partly grown one in the same vicinity. This must be the extreme easternmost limit of this subspecies in the "section". Also, Mrs. G. and Dixon have both seen individuals of the snow-shoe rabbit (Lepus w. klamathensis).
