On going away, Billy and I took a run up the canyon. Billy was in high spirits, and went racing up the narrow road, winding and turning through the chaparral, brushing me against the the stiff scrub oak and loping under low branches so fast that the sharp leaves snapped back, stinging my cheeks. We had a gay ride, with a spice of excitement thrown in; for on our way home, in the thick dust across our path, besides the pretty quail tracks that made wall-paper patterns on the road, were the straight trails of gopher snakes, and the scalloped one of a rattlesnake we had been just too late to meet.
At our next session with the blue-grays, when she was on the nest, her mate came back to relieve her and cried in his quick cheerful way, "Here I am, here I am!" Either she was taking a nap or didn't want to stir, for she didn't budge till he called insistently, "_Here_ I am, _here_ I am!" Then he hopped down in her place, and raising his head above the nest, remarked again, as if commenting upon the new situation, "Here I am!"
It was quite a different matter when she came back to work. She only called "hello," not even hinting that he should make way for her, but he hopped off at the first sound of her voice, flying away promptly to another tree and calling back like a gleeful boy let out of school, "Here I am!"
She was no more eager to go to the nest than he, however, and once when she came flirting leisurely along from twig to twig, she stopped a long time on the edge of the nest and leaned over, presumably to arrange the eggs; perhaps she and her mate had different views as to their proper positions. The next time I visited the gnats, she acted as if she really could not make up her mind to settle down to brooding on such a beautiful morning. The fog had cleared away and the air was fresh and full of life; goldfinches and lazuli buntings were singing merrily, and light-hearted vireos were shouting _chick-a-de-chick'-de-villet'_ from the brush. How much pleasanter it would be for such an airy fairy to go off for a race with her mate than to settle down demurely tucked into a cup! "Tsang," she cried impatiently as she flew up to catch a fly. She flirted about the branches, whipped up in front of the nest, couldn't make up her mind to go in, and flounced off again. But the eggs would get cold if she didn't cover them, so back she came, hopped up on the edge of the nest, and stood twisting and turning, glancing this way and that as though for a fly to chase, till she happened to look down at the eggs; then she whipped her tail, dropped in and--jumped out again!
