Just for comparison: Last week’s M.m.heermanni compared with this week’s M.m.pusillula. If you were guided by an awareness of each one’s range, and a drawing like this, do you think you could tell them apart? That is the goal of my Song Sparrow Project. I hope to continue with these drawings and accompany them with maps and descriptions. I also invite those familiar with these populations to provide constructive criticism and perhaps additional reference shots.
