6 November 2015 – Song Sparrow

This one, evidently collided and cat-scavenged, presented an identification challenge. The remaining feathers strongly suggested Melospiza sparrow, but it was really the pattern on the undertail coverts and other contour feathers that provided the necessary clues as to which one.  Ultimately, the black centers in a dark brown band on a lighter feather are congruent with Song Sparrow, but not Lincoln’s.
