Catharasta maccasumucki
been 15-18 pairs Total - I moved 2
finally on the ice before the shrewy &
Ron got 2 with roches. All were
killed in a titlene in a plastic bag
which was put over their head. It
worked very effectively.
While trying to moor birds I had
one grizzled character defend the
bait as a territory. He would not
eat himself but tried to keep others
away. The interesting thing was
seeing him announce on the wing
with wings held V & a long glide calling
as he did so. Earlier this or another
bird did the same thing near the
glacier, a "V" glide which however,
ended by the bird landing on the
ice - There the only 2 real genuine "V"
glide announcements I have seen.
Nov. 23 Pair 25 has produced an egg which
is abnormally small. It is approximately
1 1/2 inches long & proportionately wide.
Lack of defenesseness of birds with
107 shortly after the second egg is
noticeable. Today one bird which had
an egg now simply left it at
my approach with no reaction. This
makes detection of early nests some-
