The situation is quite different on the breeding ground. Here the
birds resort to a group of trees, and confine their feeding activities
almost exclusively to them. Frank Bolles (1891), in his study of the
bird in the region about Mount Chocorua, N. H., terms these stations
“orchards.” He describes one of them as consisting “of about a dozen
canoe birches and red maples, most of which were dead, some decayed
and fallen. The tree most recently tapped was a red maple about forty
feet high and two feet through at the butt.” Of another “orchard,” half
a mile away, he says: “The tree in use last year was nearly dead. Two
neighboring birches showing scars of earlier years were quite dead.
All stood on the crest of a kame. About three rods along the ridge to
the eastward a red oak and two or three canoe birches were in use by
the birds.” This report shows that sapsuckers undoubtedly cause the
death of many trees as they return to their “orchards” year after year,
but most of these trees are of small value, especially in the heavily
forested regions where the birds commonly breed.
Bolles (1891) also notes the association of the sapsuckers with the
ruby-throated hummingbirds, which were attracted to the pits by the
running sap. In the main, hosts and guests got along well enough
together, although attacks occurred on both sides from time to time.
He says: “My notes refer again and again to the spiteful treatment of
the Hummers at Orchard No. 1. On the other hand at Orchard No. 2 they
say ‘Male and young one dipping. Hummer comes in and dips several times
_between them_ and they offer no objection.’”
Major Bendire (1895), half in jest, we may presume, brings an
accusation of inebriety against the sapsucker in these words:
That it should be fond of the sweet sap of trees does not
surprise me, as this contains considerable nourishment,
and likewise attracts a good many insects, which the birds
eat; but it is not so easy to account for its especial
predilection for the sap of the mountain ash, which
has a decidedly bitter taste, and I believe possesses
intoxicating properties, unless it be taken for the latter
purpose; and the fact that after drinking freely of the sap
of this tree it may often be seen clinging to the trunk for
hours at a time, as if stupefied, seems to confirm this
view. It is well known that some of our birds indulge in
such disreputable practices, and possibly this species must
be included in the number, as there are sots among birds as
well as among the genus _Homo_.
_Voice._--Just as the sapsucker in its behavior is conspicuous, almost
boisterous, at one season of the year and retiring and unobtrusive at
another, in the same way it is very noisy in spring and the early part
of the nesting period and comparatively silent afterward.
