Activity #1 - Sitting in my backyard for morning coffee, I saw 5 house finches, 2 morning doves, 1 Anna's Hummingbird and 2 Allen's Humming birds, 1 spotted towhee, 1 song sparrow, 3 lesser gold finches, 1 black phoebe, and 1 mocking bird.
This is exercise 4. One of my favorite birds is spotted towhee, the one of the first I learned to identify . Its size is between a sparrow and a robin. It has rust colored flank, white belly, black head/hood, black wings with white spots, and devilish looking red eyes. It likes to forage in the low shrub and on the ground, but will perch at a higher branch to sing. I don't know how to describe its sound other than to say that it is a very loud and distinctive trill. It uses both feet to scratch away leaves or dirt to find its food. So in an area with lots of dried leaves and other debris son the ground, between its song and its foraging technique, it's easy to "hear" and ID it even without being able to spot it right away.
