The Song Sparrow Project continues. M.m.pusillula, or the “Alameda” Song Sparrow occupies the a very narrow salt marsh strip in the South Bay—no more than a few yards from the tidal pickle weed. It is limited in its range, and we are lucky to see this threatened population any day we visit the Palo Alto Baylands, or Hayward Shoreline. If you are wondering why this population is “of concern” consider how a full 95% of this habitat has been developed in the last 100 years! When searching for the subspecies, look for the olive nape and base color of the back, the buttery malar and the dark blackish brown streaks on a pale yellow breast.
