I asked Mark Dettling of Point Blue for an update
on this project and it is pasted in below. I too
have been seeing these banded birds regularly at
the east end of the Concrete Bridge - all adults
this winter. I presume these are all nuttalli (as
opposed to pugentensis) but I don't know this for certain. Cheers, Peter
These WCSP are part of a study that Elizabeth
Derryberry (now at the University of Knoxville)
has been running investigating differences in
song between urban (the SF birds) and rural (the
Bolinas/Pt Reyes birds) sites. The most recent
grad student to work on the project is Ruth
Simberloff. Our current lead bander at Palo, Mike
Mahoney, worked with Ruth last year and might
provide more detail (and pass along the sighting
to Ruth). They banded at both Lobos Creek and
Lake Merced, so these are their birds.
