Hastings Reservation
25May 1040. 9m, #264 and a 8 sitting out in the perch tree.
1130. Returned and opened the hole where the 8 had been yesterday.
As far as I could tell, it was still being built and no eggs were
present. The problem is that the limb is virtually horizontal
and the hole goes down at an angle and, connecting to the
hollow cavity of the limb, continues sideways virtually indefinitely.
Thus I suppose it's not impossible that their eggs are several feet
back out of reach. Either way, I'm going to wait for something
else more definite before digging deeper anywhere.
27May 1900. Bird in the hole in the Valley Oak- out toward Al near
the road. Nobody in the other holes. Maybe that's it, but if so
it will have to wait a few days.
30May 1845. 8/108 sitting in perch tree, nobody else seen in/out of holes.
31May 1530. Nobody at all seen in/out of holes. Also, these birds are
out of stores.
3June Nobody seen in holes; 1 bird in the vicinity again.
5June " " " " " " (not perched).
Some calling heard downslope. (Time 1845).
8June 1845. Pub sitting in perch tree; flew down and into forest in
Lambert direction. Must be something back there.
10June 1900. Bird in hole in tree next to the road where I ambushed last
month.
14June See Keep Out notes for brief territorial encounter between 88
of this group and KeepOut 8 along their border.
Nobody seen when I walked by and checked holes about 1915.
Several birds heard over here at dusk, however.
24June 1215. Both 88 seen in perch area. Bands not seen particularly well.
