10 Nov Watching from hide, 1100. A good start; As I walk
up I confirm ♂590 M/Dgreen-Lgreen, who was questionable
last time I watched. 1230, bad finish: Absolutely nothing
else; No wakas, no birds, a big zero.
3 Dec Trying again, 0900. I again see ♂590 M/Dgreen-Lgreen
and ♂123 DBlue/Metal as I walk up. A third bird seen
as well. After that, zilch! End 1030
11 Dec Counted stores, 1500.
"Secondary" tree 1100 (many old)
"Main" tree 750 ("", chrysolepis)
Lots of last years acorns TOTAL 1850
mostly chrysolepis, some agrifolia.
