As always, I'm color-marking hummingbirds in 1999 in York and at Hawk Mountain.

REQUEST FOR INFORMATION ON SIGHTINGS OF COLOR-MARKED RUBY-THROATED HUMMINGBIRDS
(Please forward this posting to other appropriate lists to which
you may subscribe.)
Fall migration of Ruby-throated Hummingbirds (Archilochus colubris)
is under way in the northcentral Piedmont of South Carolina. I have
been banding hummingbirds here at Hilton Pond near York SC (just
south and west
of Charlotte NC) since 1984. Although the Piedmont seems NOT to be a
hummingbird migrational pathway or staging area, through 20 September
1999, I have still managed to capture and band 2,004 RTHU, and have
retrapped many RTHU in subsequent years after banding.
To minimize recapture of banded hummingbirds in my pull-string traps,
I am authorized by the federal Bird Banding Lab to mark each bird
from York with non-toxic GREEN dye on the upper breast and throat.
(In fact, I
use a so-called "permanent" felt-tip marker, but the dye wears or
washes off within a month or so.) In early August I also banded RTHU
at Hawk Mountain Sanctuary in Kempton, Pennsylvania, using BLUE dye.
Because we know little about actual overland migrational pathways for
hummingbirds, I would appreciate hearing about any sightings you may
have of color-marked hummingbirds during migration this spring and
fall.
Color-marking of hummingbirds here at Hilton Pond paid off in October
1991 when a woman in Atlanta saw an "unusual" hummingbird with a
green throat and called Bob Sargent, a fellow hummingbird bander from
Alabama. Bob drove to Atlanta, trapped the bird, and after reading
the band number learned I had banded it in South Carolina. This, to
the best of our knowledge, was the first report of a banded
Ruby-throated Hummingbird to be recaptured and released away from its
original banding site.
In FAll 1997, a woman in Louisiana, sighted another "green-throated"
hummingbird that was likely a RTHU banded here in York; this sighting
further supports the idea that at least some East Coast RTHU migrate
not to south Florida but to the Texas Gulf Coast before a trans-Gulf
or Mexican overland crossing. This bird may also have been the first
"long-distance" sighting of a marked RTHU.
If you see a color-marked hummer, do not attempt to trap it (it's
against federal law to do so unless you have a special permit), but
please contact me at my personal e-mail address below (I'm not
currently subscribed to
BIRDCHAT or HUMNET) or at my home phone. If you find a dead banded
bird, read the band number and also contact the Bird Banding Lab at
1-800-327-BAND or via their reporting website page at
http://www.pwrc.usgs.gov/bbl/homepage/recwbnd.htm.
Thanks for any help you can provide in taking close looks at
hummingbirds at your feeders during the fall of 1999 and again next
spring.
