Not nearly so numerous as in former
years but still very common all about
the shores of the Lake wherever plenty
of stumps are still to be found. The colony
at the Outlets comprised about 18 pairs.
When there were but few stumps we found
scattered pairs, sometimes only one to a large cove.
May 27. Two birds driven out of
holes - old Woodpeckers holes -
where they seemed to be settling.
