48 THE CONDOR I VoL. VII spot was reached no bird was in sight, and a little later it would again be heard calling far off to one side. We persevered, occasionally catching a glimpse of a small bird flitting through the tree tops, and finally Mr. Stephens fired and picked up what proved to be a full grown juvenile. While examining this bird, the peculiar, twittering note was again heard on both sides, and we again started in pursuit. I followed my bird in vain fi)r a long time. and finally prepared to give it up; but, while standing behind a thick bush, two of the birds darted over me and lit close by, where one could be seen feeding the other The young bird left almost immediately, and I fired and killed what proved to be an adult male. This ended our flycatcher hunt, for we neither saw nor heard them again. Those we saw were probably a single pair x?,ith their brood. They are birds that it would be exceedingly easy to overlook, since they are small and dull colored, and keep in the tops of the tallest trees as well; while, judging from those we saw, they would seem to be exceedingly shy and hard to approach. It was withil? a few miles of where we shot these birds that Mr. Stephens secured the type specimens in is8?; and I can find no record of tile capture of any others since that time. I have looked for them in vain in other parts of Arizona. Corvus c. sinuatus. American Raven. An adult male in very fine plum- age was shot by Mr. Stephens; several others were seen. Corvus crypt01eucus. White-necked Raven. Very common; seen mostly in the open pastures. Nearly all that were seen seenled to be moulting, and were exceedingly disreputable in appearance. lI010thxus a. 0bscurus. Dwarf Cowbird. Exceedingly common all through the mesquite forest. Agelaius ph(eniceus subsp? Red-winged Blackbird. A few red-wings were seen on one or two occasions flying about over the Indians' grain fields, but none were secured. Some breeding birds I secured on tile San Pedro River were identified by Mr. Ridgeway as neztlralis, so those seen on the Santa Cruz may have been of this variety, or sonoriensis. Icterus c. nels0ni. Arizona Hooded Oriole. Exceedingly common; breeding everywhere in the mesquite forest. Icterus bul10cki. Bullock Oriole. Not nearly so common as the last. Ch0ndestes g. strigatus. Western Lark Sparrow. One or two pairs were seen about the edges of the mesqhites; they are not at all common in this region. Amphispiza b. desertic01a. Desert Sparrow. Very common everywhere on the open, brush-covered mesas. A few were seen about the edges of the mes- quites, but none in the thick forests. Pipi10 f. mes01eucus. Canyon Towbee. Fairly common and breeding in the big mesquites. Pipilo aberti. Abert Towbee. Breeds in linfited numbers in the mesquite forests. It is not nearly so abundant as the last, and the birds are so shy and re- tiring that they are hard to catch sight of. Cardinalis c. superbus. Arizona Cardinal. In x9o2 I saw a good many car- dinals in the mesquites, but in ?9o3 they seenled to be ahuost entirely absent, the only one observed being a single male bird. Pyrrhu10xia sinuata. Arizona Pyrrhuloxia. 'Fairly common, and often heard singing about the camp. A nest with three eggs was found built in a scraggly mesquite bush at the edge of an Indian field. The nest was not concealed at all and I saw the female fly to it when still a long way off. Both birds stayed around
