Northern Shrike and these birds with the ones just
mentioned, and the ever faithful Permanent Residents, give us a goodly
winter company.

But the possibilities do not end here; there may be Redpolls, American
and also White-winged Crossbills, perhaps Pine Grosbeaks, and, best of
all, Evening Grosbeaks, who of recent years have been coming to us more
or less regularly from no man knows where.

So from one year's end to the other, there is not a month, a week or day
which has not interests of its own. The bird student may pass his life
in one place, but he can never say "I have finished" for the morrow may
bring some new bird or new fact. How immeasurably this association with
the birds adds to the joy of life! What new meanings their comings and
goings give to the changing seasons; the very air is made eloquent by
their calls and songs. Why should we not all "come at these
enchantments"?
