He is a federally-permitted hummingbird bander and serves as Vice President of the Minnesota Ornithologists' Union. He is a Goodhue County Master Gardener and attracts hundreds of hummingbirds annually to his garden near the Mississippi River in Red Wing.
WHY BAND HUMMINGBIRDS
Bird banding is a very important tool in ornithological research. When a bird is banded, important data about the bird such as age, sex, condition, and plumage and characteristics may be collected. The information may also included making any number of measurements, especially the wing chord (length of the flattened wing from wrist to tip of the longest primary feather), tail length, mass, and bill length. After the banding the bird is released, the data is filed the Bird Banding Laboratory, including precise information about date and location of capture. If someone encounters the bird at a later date, the band number can be reported toll-free at 1-800-327-BAND or through the BBL's Web site. Contact is then made with the bander and is informed as to where and when the banded bird was found and by whom. The finder receives a Certificate of Appreciation and is told where and when the bird was banded.
HOW HUMMINGBIRDS ARE BANDED
Once a hummingbird is captured,
it must be temporarily immobilized so it can
be banded and measured. Different hummingbird
banders use different techniques for holding
the birds; some place them in mesh lingerie
bags and gently pull the birds leg through
an opening for banding.
Others use the technique of placing hummingbirds
carefully headfirst into a small paper tube
slightly larger than the bird. While in the
tube, the hummingbird can't struggle and hurt
itself, and it can be banded and measured.
The bander places a partially opened hummingbird
band (which had been formed previously) into
special banding pliers and slides it over
the leg of the bird. The band is then crimped
shut and checked to assure that it is perfectly
round and fits well. A common method used
is to band all male Ruby-throated Hummingbirds
on the LEFT leg, females on the RIGHT.
