In the Monterey section this bird nests abundantly throughout the brush-cov- ered areas tributary to streams; and it is especially partial to the shelter of black- berry vines. Mr. O. P. Silli- man, of Salinas, who prob- ably has had more experience with the Golden Pileolated Warbler than any other liv- ing collector, tells me that as a lad he has taken as many as ten sets in a single morn- ing "on the way to school" near the Pajaro River. He found them nesting in late or middle April, and again in later May. A nest before me from this section is made of materials culled from river drift,—dirt-incrusted twigs, root- lets, and macerated bark, together with the wastage of trees,—leaf skeletons, catkins, and the like. The lining is of fine rootlets, skeletonized leaves, and a few strands of horsehair. This structure represents an enormous amount of labor; but it is quite outdone by an exquisite moss-ball from Humboldt County, which was collected by John M. Davis, of Eureka. This was placed two feet high in a cluster of ferns, and consists of little else than most exquisitely compacted moss, with walls over an inch in thickness. I cut through one side of this nest with a razor, intending to count its component strands, but I was appalled by the task presented and promptly sewed it up again. This birdie assuredly has more time than a busy bird-man. And it is a satisfaction to know that when one home is requisitioned in the name of science, another as exquisite is pre- pared within a week or ten days. Such birds as are impelled to nest along the willow-lined streams of the San Diegan district appear to adjourn to the higher levels for t
