Matt White Sitting on my mantle is a silver – colored aluminum ring large enough to fit around a man’s thumb. Made of the basest of metals, it has no real monetary value. Although it is an unlikely keepsake, I keep it as a souvenir because the numbers stamped on it tell a fascinating story about the life of a bird that otherwise would be nothing more than an unknown drama carried out behind the veil that for centuries shrouded the mystery of bird migration.
Technically speaking, it is a bird band. Licensed
ornithologists are allowed to place very small, lightweight aluminum bands
around the legs of birds in an attempt to determine where they migrate.
Its value to me lies in the fact that by recovering this ring, I was able
to contribute a tiny pixel in an image that is still emerging.
When I found the ring, it was still firmly wrapped around the right
leg of a large dead American White Pelican. Only one tenth of
one percent of the birds that get banded are ever recovered, so I
contacted the Bird Banding Laboratory at the Patuxent Wildlife Research
Center in Maryland about my find and gave them number on the band.
A few weeks later I received a certificate in the mail telling me
the story of the pelican that I had found dead.
As it turned out, the bird had been banded in June shortly after
hatching in Minnesota. In
August, when I found it, it was only two months old, yet had flown 1000
miles due south, only to die and be eaten by fire ants in northeast Texas.
It is an incredible story. While
we still know very little about that bird, the history of this single
individual is now chartable on a map. We have a beginning point, and an
ending point. Although
it might not reveal how and why this fully grown bird—though only two
months old—was able to fledge and migrate so far so south so quickly, we
have data to reveal that it did. Why
did the bird leave Minnesota in August, well before the arrival of cold
weather? What drew the bird to Texas in August, when the temperature
is still in triple digits?
I do not have the answers to these questions.
But one of the reasons that birds are worth watching is because
they force us to ask questions and to look for answers to those questions.
If nothing else, they fill our idle thoughts with wonder and spark
our imagination about birds that can leap frog continents and jump
thousands of miles in a single bound.
Although I digress, these are things that for me make life worth
living.
Perhaps that pelican headed to our corner of the state because of
our reservoirs. Pelicans eat small fish, and so it stands to reason that
they would hang out near water. One
hundred years ago, the sighting of pelican was thought to be quite
noteworthy (because there were no large man-made lakes to attract them).
Many people think of pelicans as primarily inhabiting coastal
areas, yet American White Pelicans are regular visitors to the lakes and
reservoirs in our corner of the state; they do not breed here.
A few, however, do remain during the summer. Brown Pelicans, on the other hand are mostly coastal birds,
but have wandered to a few of our lakes as well.
Either way, these huge birds have a wingspan of nearly ten feet and
are show stoppers when they arrive. To
call them entertaining would be an understatement.
