> I just got some wonderful news this afternoon. A female rufous hummingbird
> that I banded on January 13, 2010 at Pam Flynn's house in Tallahassee was
> recaptured today in Chenega Bay, Alaska, nearly 4,000 miles away. When I
> examined the bird I checked its bill and found that about 50% of it
> contained striations, indicating that this bird was born last summer.
> Instead of migrating south to Mexico like most rufous, it came east and
> spent the winter here. This recapture is by far the greatest distance
> between banding site and breeding grounds. One of the previous long
> distances was a bird recaptured here after being banded in west Texas,
> about 980 miles. That one really pales compared to this bird. I'm not sure
> what the previous record was but I think this may be 1,200 miles longer.
> One reason is that there are few banders in Alaska to band and recapture
> birds in the NW end of their territory.
> I have posted some photos of this bird that I took when I banded it, at
> http://upload.pbase.com/edit_gallery/fdietrich/alaska. The last page is a
> record of the data that I collected and reported to the Bird Banding
> Laboratory in Maryland, the repository of all data that is collected
> through bird banding.
> While it has long been believed that the birds that winter in the SE
> states may have come from as far away as Alaska, this is the first time
> that we have been able to document it on both ends of the migration route.
> Without banding hummingbirds, we would have no idea of their migration
> habits. Obviously there was no harm done to this bird during banding and
> carrying the band didn't affect its ability to fly. The weight of the band
> is less than .02% of its body weight, many times less than the relative
> weight of a person wearing a wrist watch, and since the bird tucks its
> legs up into its body feathers when it flies, there is no increased
> aerodynamic drag caused by the band.
> I will be banding at a few homes this summer but our main research project
> continues to be banding wintering hummers, those that are here between
> November 15th and March 1st. Keep your feeders out and I'll be waiting to
> hear from you this winter, and especially to see if this long range
> migrant returns to Pam's house.
