May 28th - Adult Osprey Banding
|
On May 28th, the female ospreys from
the Wildwing Lake and Dawson Rd. nests were successfully caught and banded.
In this photo, Wildlife Biologist and bander Sergej Postupalsky, and OWSEM volunteers Val Valoppi, and Barb Jensen
are on the Huron River heading for the Dawson Rd. nest. The loop carpet
trap (between Val and Barb) and the ladder used to climp to the top of the
nest platform are important tools for this activity.
|
The loop carpet trap is attached to
the nest platform. Before landing, the female osprey can see her 3 eggs under
the wire mesh dome of this apparatus. As she lands, her feet are caught by
the many loops, preventing her from flying off.
Within a couple of minutes, the caught female and trap are retrieved and
the osprey placed into a cloth bag to restrain her and to minimize stress
when being handled.

Sergej is applying acetone to a previously
placed plastic band on the right leg of this osprey. The acetone glues the
band layers together to make the band permanent. Val is readying the
second band that will be placed above the installed band. The osprey is nestled
in the grey bag in Sergej's lap
This female also received a metal U.S. Fish and Wildlife band on her left
leg, with a plastic band above that. The unique band set used on this bird
will allow observers to easily identify her in succeeding years.
|
Once banded, the female osprey is weighed. This one was 1.83 kilograms,
or 4 pounds. Four pounds is an average weight for an adult female
osprey, while the males weigh about three pounds.
|
After weighing, each bird is closely
examined. Here, the tail feathers are being counted, and their condition
noted.
|
When all of the bands are in place and
the physical condition of the bird has been determined and recorded, she
is released to return to her nest. The total time from capture to release
takes about 30 minutes.
