Indiana Fledgling Spotted in SW Pennsylvania

In
mid-July of 2000, during a routine Friday evening stop at Moraine State Park in
southwestern PA, where I manage a 50 pair colony site, I spotted a martin
wearing an interesting leg band while looking them over with a high power
spotting scope. It was a hatching-year martin (recently fledged), and the type
of band indicated that it had fledged from a colony site in the state of
Indiana. Reading the markings on these tiny bands can be difficult, especially
in marginal lighting, and the light but steady rain and unseasonably chilly
temperature were causing me to retreat to the car to wipe off the lens of the
scope quite frequently. The banded fledgling would occasionally take off and be
gone from time to time, causing my heart to skip a beat; I really wanted to get
that number, and I my heart was pounding so fast that it was hard to be steady!
The banded martin hung out mainly on the top perch of a T-14. There were many
other martins perched in the very tall treetops at the edge of the lake, and on
the electric lines nearby. But it reappeared enough times for me to get all the
numbers, and, as I suspected, this bird had been banded in the state of
Indiana! It had fledged from the colony site of Joe Bontrager of Ligonier, IN
on June 24th, 2000, and had made its way some 300 miles ESE to the
Moraine State Park colony site in Pennsylvania, where I spotted it in the late
afternoon of July 14th, 2000, only 20 days later.
I thought it was interesting to see a fledgling
so far from its natal colony site, and in so short a time. I had driven through
a hellacious thunderstorm with strong winds on my way to the park, and I
wondered if this weather event played some part in the bird’s appearance so far
from home. We know fledglings will travel great distances prior to migration,
but it seemed a bit unusual for a fledgling from Indiana to have traveled east
to Pennsylvania. It will be interesting to see if it breeds in the area
(assuming it survives its migration to Brazil and back).
