Avian Time
by Reginald GibbonsThe collection manager of the bird specimens at the natural history
museum told of often stopping, on his way to work during spring and fall,
at the immense convention building—tall, long and wide—on the shore of
Lake Michigan, where on the north side he would gather the bodies of the
migratory birds killed by their collisions against the expanse of glass before
first light.
The north side, whether in fall or in spring—a puzzle.
Are these particular birds blown off course by winds, and do they return
in starlight or dimness before dawn or under dark clouds toward shore,
making for the large bulk they might perceive as forest?
They have been flying along this same route for tens of thousands of
years, and not yet has their thinking formulated this obstacle of the city
that has appeared in the swift stroke of a hundred and fifty cycles of their
migration.
