I then noticed a male Prairie Warbler making its way toward me through the scrub oaks, and then I saw the female lower down. They were very calmly inquisitive, no alarm calls issued, they simply advanced toward me, staying low in the oaks. I backed away slowly and found a large rock to sit on at an angle with the sun behind me and the nest about 20 feet in front of me. The warblers had probably been nearby foraging and the female now resumed her place on the nest. A good candidate for photography, I had been keeping track of this male for a little while now, and knew all of his favorite singing perches. He was tame enough to let me advance cautiously to within 15 feet while he was singing, and would predictably land in a certain spot if I waited long enough.
The female Prairie Warbler is similar to the male (pictured above) though with the greenish color of the back in place of the black streaks on the face and chest.
Yesterday I also had the chance to get very close to a very different sort of bird: the Brown Thrasher. A pair of them were very active and vocal, especially in the territory area of the Prairie Warbler pair. They landed on a tree very close to me as I crouched among the oaks, and once as I was standing up, one veered around my head, shooting like a rocket past me. Very different from the Prairie Warbler, which is smaller than even a chickadee, the Brown Thrasher is larger than an American Robin. Though like the warbler, it prefers to sing from very exposed perches.
