March 2 were observed to give begging calls. "43"
and "33" did not feed like before
when the juveniles were handled.
59 looked good, as did 273 and 274.
"40" and "06" were put back in their cell.
March 9 At A.B.S. today. Got there at about 8:30.
All birds o.k. 302 still scarred on the
upper bill, and now 302 has lost the
tenure tail. "33" was observed to
carry a large piece of dry grass, and
a nest was seen to be started
in an old pine (Douglas Fir) bough in
the cell! 301 & 302 were transferred
to cell with "59". First, 301 was
put in... "59" chittered and gave the
"brrip-brrew" phrase -- many times -- 301 also chittered.
302 was put in next. Both seemed
to be light in weight -- thin. "59
showed no hostility to the juveniles.
I then cleaned-up all 4 cells, put
in a few fresh boughs. No nestings
from "40" and "06", but song from "40".
No song from 273, no courtship
feeding observed between either 273/274
or "40"/"06". The juveniles 311 & 302
