1978 Walter D. Koenig Melanerpes formicivorus Hastings Reservation, Monterey Co., Calif. 23 June Returned late this morning to the Blonquist Ranch at Corral Viejo Canyon (near the Windmill [on USGS map]) and opened the 2 nests I found on 18 June. The first had 3 babies about 17-18 days old who were marked as measured as: (1) 73.2 gm [43mm] Or-Brn (2) 67.3 [44] Blk-Wht (3) 64.4 [38] LP-Wht(n) This was the first nest between the Windmill and the main road on the map on p. 21.

On the limb (horizontal) directly behind it, however, I found at least 20 or more reniges emerging from their sheaths which had been plucked or otherwise taken from baby woodpeckers too young to fledge. I found no
