Banding the Eyasses

With the able assistance of Denise Kolb of Wright Runstad, we will be banding the eyasses on the ledge at WAMU this Thursday.

We use the window washing stage to swing out over the east side of the building and lower us down to the nest ledge 53 stories above street level.

Each eyass will receive a US Fish and Wildlife Service aluminum lock-on band on one leg and a black VID band on the other. The latter may be easily read with a spotting scope to help us identify individual peregrines.

We have done this each year in Seattle and have tracked the whereabouts of many of the eyasses over the years.

Nestlings have shown up on the Washington coast, the Oregon coast, San Francisco and the LA airport. Others have made it as far east as Alberta. In addition, there are several records of banded nestlings from Washington wintering in both Victoria and Vancouver.

In several cases, these bands have allowed us to discover where the nestlings eventually breed as adults.
