Not many yards below the vesper's nest, on the other side of the road, is a junco's nest. You may know the junco's nest from that of any other ground-builder by its being more elaborate and more perfectly hidden. The nest is tucked far under the mossy and weedy bank, and only a nest-hunter passing along the road, with "eye practiced like a blind man's touch" and with juncos in mind, would have seen it. A little screen of leaves of the hawkweed permits only the rim of one edge of the nest to be seen. Not till I stooped down and reached forth my hand did the mother bird come fluttering out and go down the road with drooping wings and spread tail, the white quills of the latter fairly lighting up the whole performance. A very shy and artful bird is the junco. I had had brief glimpses of the male many times about the place. The morning I found the nest I had seen one male spitefully pursuing another male along the top of the stone wall opposite, which fact, paralleled in a human case, would afford a hint for detectives to work on. The junco is evidently a very successful bird. The swarms of them that one sees in the late fall and in the early winter going south is good evidence of this. They usually precede the white-throats north in the spring, but a few linger and breed in the high altitude of the Catskills. When the sun shines hot the sparrow in front of my door makes herself into a sunshade to protect her nestlings. She pants with the heat, and her young pant too; they would probably perish were not the direct rays of the sun kept from them. Another vesper sparrow's nest yonder in the hill pasture, from which we flushed the bird in our walk, might be considered in danger from a large herd of dairy cows, but it is wisely placed in view of such a contingency. It is at the foot of a stalk of Canada thistle about a foot and a half high, and where, for a few square yards, the grazing is very poor. I do not think that the chances are one in fifty that the hoof of a cow will find it. I do not suppose that the problem presented itself to the bird as it does to me, but her instinct was as sure a guide as my reason is to me--or a surer one.
