 Mar.,1908 SOME NOTES AND RECORDS iROM THE WHETSTONE MOUNTAINS 77 trees. Examples of C. uropygialis secured at this period, were all discolored about the forehead and chin with juice of Opuntia fruit. Altho I well knew I was within the described range of Z)ryobates arizone, several days passed before a noise, leading one to the suspicion that it was the rapping of a small woodpecker, drew attention. It was not a loud sound, and being inter- spersed with periods of silence, made the clew somewhat difficult to follow; thus some time elapsed before reaching the origin of the noise. Here a  ]). arizonee was working on an oak-trunk, not three feet above the base; while the trees around harbored unnumbered Bridled Tits (5?eolophus wollweberi), Lead-colored Bush- tits (Psaltriparus plumbeus) and Rocky Mountain Nuthatches (Sitta carolinenss nelsoni). Very often did I run across a similar assemblage, but rarely were there more than one or two Arizona Woodpeckers in it. There is no recollection at hand, of noting above four adult woodpeckers of this species in view at once; more likely to chance upon a solitary individual than a pair at any time. The noisiest occasion I can accredit to the species occurred one spring day,' when two adult females were located, perched upon a horizontal limb of a madrona, facing each other, and emitting a continuous volume of characteristic woodpecker notes, the effect being hightened by that peculiar muscular movement which accompanies the vocal utterances of some Pici. The continuity was possible by a relay system; and so engrossed were the participants, that I approached to directly under the limb and stood there at least two minutes, without being detected. Taken as a rule, the Arizona Woodpecker is quite indifferent to one's presence; nevertheless it can be erratic at times. This is best observed during the breeding season, which may be counted as May here (this year only). Few male birds are then to be found, except on the lower declivities of the range, where they are nearly as difficult of approach as the largest members of the family. There is a certain ravine here, that might with propriety be called Flycatcher Canyon. It was the delight of several of the species, that would be looked for in vain elsewhere in the range. So along this canyon, well up toward the neutral ground of oak and pine, the lonely Olivaceous Flycatcher (Ffyiarchus lawrencei olivascens) dwelt. 'It was a late comer tho, and not until June 9, did I secure any. On two occasions a pair were seen; all others as single individuals. Their note given at measured intervals was long drawn out, and of a single syllable. Tameness is of the usual Tyrannide average. The same canyon was the sole resting ground of such Olive-sided Flycatchers (2Vultallornis borealis) as were recorded. Spending odd days here between Sep- tember 6 and 17, it contrived to form a temporary brotherhood with a near relative, the Western Pewee (Conlopus richardsonii). An amusing situation was developed on several occasions; the two species were observed side by side, on some dead bunch of trees growing on the canyon's side. Affinity in color and movement, and similarity in note, however, did not offset the disparagement in size. Jays--three representatives of the group here. The Arizona Jay (Aphelocoma sieberi arizone), of whom every collector coming within its habitat will have a changing opinion, as to the advisability of existence as a link in the avian chain of nature: Depending on whether you are out to study its habits; or whether an in- terview with a varied bird life be frustrated by A. s. arizonie spying you out and declaiming the discovery with enthusiasm for many minutes. But after all, its per- sonality overbalances the hereditary meanness. Economically, it certainly. does no harm. For dissect one and examine its craw any time before the acorns come, and you will find remains of Carabid, Elator, Buprestid and other beetles; true bugs of
