1979 Walter D. Koenig Melanerpes formicivorus Westgate Hastings Reservation 19 January Counted stores: Gabletree: 0 ? Weate: 350 350. One bird flushed in the process. 21 January 1050. Watching. 1115. 0° or-wym #258. 1130. #258 here hawking in Gate sycamore. None else here. 1145. There are at least 2 birds far up on the chaparral slope, one perching on a dead Adenostoma. 1150. Leaving. Doesn't seem to be the day for this group. 1200. Down by Hellisey's is 0°M/Blk-#466. Flew up to that death Adenostoma bush. 6 February #258 seen in Gate sycamore in passing. 9 February 1635. 8 Pa/16-16 #467 flushed from the top hole in the Willow nest tree. 15 February 1200. Watching. 1230. Wandered around as well as sitting for a spell with only 1 brief look at a 0° in the Gate sycamore. 25 February Ron watched here yesterday and today, and I watched for an hour or so in the late afternoon, all seeing about the same set of 4 birds sapsucking near the Weate sycamore: 0°58, 0°ub, 0°258, and 0°ub. No sign of any babies (!) Ron saw lots of dominance-subordinate interactions (see his notes); I particularly noted 0°258 being constantly submissive (giving Chetter calls) in the presence of 0°58. Very few stores remain here - but I did note a few apparently intact ones. Also I watched at dusk, but didn't see anybody roost in the willow or the Gate
