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
