Re: Banded White-crowned sparrow
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, Petertoggle quoted messageShow quoted text
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.

This may be one of the banded White-crowned Sparrows from a research project in 2014 and 2015. 41 White-crowned Sparrows were banded in SF in 2014 (unknown location) and additional White-crowned Sparrows were banded in 2015 at Lake Merced near the Concrete Bridge, and at Golden Gate Park near the Polo Fields.
