1978 Walter D. Koenig Melanerpes formicivorus Hastings Reservation, Monterey Co., Calif. (18 April) directly between Lambert group and Near Lambert has fallen. This tree had no storage holes but did have 1-2 woodpecker-sized roost holes, and in any case was a venerable old lobata. ② there are quite a few steres remaining at Near Lambert, and ③ I flushed 3 birds, 1 or 2 out of one of the holes in the roost tree near the granary.
