Holmes,R.
1959
7 July Barron's Alaska.
The afternoon was spent in searching in the vicinity of NACS
for more nests. Since the birds
are no longer displaying
territorial size cannot be
accurately determined. The
spacing in the nests and the
positioning of some of the birds
is indicated below:
If a square is made
which includes all
four nests it contains
an area of about 81,000
sq feet or 2 nests per
crarr. Of course there
is not including the
ranges these birds
and since displays
for their concluded
boundaries cannot
be definitely established
The numbers by themselves
indicate when The
adult birds have been seen
away from the nest area.
