14 April 12:50 - Nobody seen in a hole
1 May 15:30 - Bird in hole; hear babies after it leaves.
Same hole that I thought bird came out of about
5 days ago (claring roost with no nest taken)
New hole in poison oak surrounded tree
located just below hole used last year for
nesting.
2 May 13:30 - Finally made it through all the poison oak
(cut most of it away) and opened hole. 7 babies!!
10g to 23g. Only the 110g bird is significantly smaller;
the rest are about the same size (~23g)
17 MAY Banded
10 June 9:45 - No birds seen in a hole - Still plenty of acorns
13 June 10:20 - Two fledglings flew from nest hole
located in (is black oak?) towards briaq. (hole
opens downward), I hope those were PHOBO fledglings
and not some other group (i.e. SOBO)
