Rostorer 1944 Red-breasted Nuthatch. February 10 Univ. Calif. Campus, Berkeley, Calif. 5 PM Saw a brightly colored bird of this species with somewhat more rufous underneath than usual. The bird was working on a hole about 2" in dia. in a branch of a Monterey Pine (P. radiata) 100 yd. W. of the Hearst Mining building. The hole was a natural one where a branch had been broken or cut off. The wood was evidently rotting and a few small flakes floated to the ground while the bird was working. I don't know whether the bird was excavating a roost or nest site or just after food. However, it will be worth while following up. February 18 Francis Pitellsa says that Joe Marshall found a brood of young in the Eucalyptus grove just west of H.S.B. last summer or the summer before, but failed to record it.
