Nest of Blue Jays at Ball's Hill

time for I was in plain view of the nest &
very near it, walking along the path. Strange
to say a pair of Robins have succeeded in rearing
two young in a nest in a pine not more than
thirty yards from the Blue Jays' nest. Their young
took flight this afternoon. Their nest had only two
eggs when we first noticed it. At that time the
Jays were beginning their nest. For several days
after this there were frequent outcries from the
Robins which we saw repeatedly chasing the Jays
away from the neighborhood of [the] nest. Whether or not the Jays
seriously attempted to rob it I do not know.
Perhaps they may have succeeded in getting part of
the eggs for Robins almost always lay more than
two.
