  The Pileated Woodpecker was by no means the only
birds which had chosen the pretty little mountain glen
above described as their summer home. There were also
Blackburnian, Magnolia, Black-throated Blue, and Canadian
Warblers, Oven-birds, Red-eyed Vireos, a Wood Pewee
and an Olive-sided Flycatcher, a drumming Partridge,
and still others that I cannot now recall, in the
undergrowth or tree tops close about our place of concealment
at the base of a giant spruce. But most interesting and
impressive of all the sounds that came to our ears from
the surrounding forest was the hooting of a pair of
Barred Owls. Soon after reaching the glen I clapped my 
hollowed hands together a number of times in quick
succession and in such a manner as to produce a sound
not unlike that of a Woodpecker pecking at a rotten
tree trunk. By this means I have often called a Pileated
Woodpecker from a considerable distance, but in the present
instant the result was unexpected for instead of one of
the Woodpeckers a Barred Owl came flapping through
the woods straight towards us, alighting in a large
yellow birch some thirty yards away where it remained
for ten or fifteen minutes, hooting at short intervals. At
the time we all supposed that its appearance was due
to mere coincidence but after it had flown away I
called it back again three successive times by the same novel
means. On each of these subsequent occasions it hooted for
fully as long a period as during its first visit being regularly
assured by its mate from a distant point in the valley
below. Its voice rang and echoed through the deep,
moss-grown woods thrilling and delighting my senses as
did no other sounds heard on this occasion. Abbott Thayer
found a young bird which he thinks belonged to this pair of Owls on the ground
near a big hollow maple a week or two ago. It was then nearly fully grown.
