This is my second haptic drawn to (mostly) bird song. You can view the first one here. I used my new Prismacolor, “premier” two-ended brush pen. I like the way it handles — the large end can make thick dark strokes AND very thin light strokes, depending on the pressure you exert with your fingers. It was a gorgeous day, with bees buzzing, and lots of crow cawing, because the crows are nesting and they get noisy this time of year. Also a lot of sparrow, towhee, and junco songs, which are more high-pitched and warbley.
