This is a ONLY proof-of-concept of the generalized Song Sparrow template. My first subject is M.m.heermanni, otherwise known as the “California Song Sparrow”. It is probably the most widespread population, yet coastal birders in Northern California need to drive a little to see them. They are marked with more pale gray and medium rufous contrast than M.m.gouldii or the various salt marsh populations. I quickly added color to a poor quality laser print out of the pencil template. Some ambiguity around the scapulars and median coverts will require some work, maybe some adjustment on the template… The template (and the coloration) was modeled after an individual photographed during our annual Gray Lodge tour. It remains to be seen if I can translate other populations on this architecture.
