 110 THeE CONDOR VoL. X through the higher parts of the mountains, from about 6000 feet upwards. Not observed in the Rincons. Dryobates scalaris bairdi. Texas Woodpecker. Fairly common in the foot- hill region of the Huachucas, while a few were seen in the Rincon Mountains also. They are less dependent on the presence of large timber than most of the wood- peckers, and may frequently be seen feeding in the "greasewood" and on the flat- leaved cactus (Opuit'a), sometimes a long way from trees. Dryobates arizon/e. Arizona Woodpecker. Fairly common in the live-oak region in the Huachucas, and seen also in the Rincons. A male birtt secured in the latter place on September 27 has one or two faded brownish feathers on the upper part of the dorsum, remnants of the old plumage, while in another secured October i the outermost primary has not acquired its full length. The molting period thus extends over quite a long period of time, fronl the middle of July to the first of October. Sphyrapicus varius nuchalis. Red-naped Sapsucker. The fist one seen, a female, was secured in the Rincon Mountains on September 27, several more being observed the following day. When we reached the Huachucas, October 1, the species was fairly abundant, and remained so the whole of our stay. It probably remains in the mountains throughout the winter. Sphyrapicus thyroideus. Williamson Sapsucker. A single specimen, a female, taken in the Huachucas, at the head of Miller canyon, about 9000 feet on October 26, was the only one seen. Melanerpes form/civorus aculeatus. Mearns Woodpecker. One of the most abundant species in the Rincons and in the live oak regions of the Huachucas. In a specimen taken on October 15 the exposed portion of the primaries is already beginning to fade to a dull brown. Centurus uropygialis. Gila Woodpecker. A few were seen in the Rincons and in the foothills of the Huachucas, but it was not common in either place. Colaptes c/der collaris. Red-shafted Flicker. By far the most abundant species of bird in the Rincon Mountains at the time of our visit. They were feed- ing on the wild grapes which grow in the greatest profusion in that region. Flick- ers were fairly abundant in the Hachucas also. Phal/enopfilus nuttalli. Poor-will. The Poor-wills had nearly all left the mountains when we arrived, and only one or two were heard calling. A bird flushed on a rocky hillside near the base of the Huachucas on October 23 was the last one noted. Aeronautes melanoleucus. White-throated Swift. This species was observed on only one or two occasions, but is probably apt to visit the mountains at any time in the winter, as it is unquestionably a resident in the warmer parts of the territory, not so very many miles away. Trochilus alexandri. Black-chinned Hummingbird. A few hmnmingbirds, not over three or four all told, probably of this species, were seen in the Rincon Mountains during the last week in September. This identification is not positive, as all that were seen were females, and none were secured. Selasphorus platycercus. Broad-tailed Hummingbird. Three or four were seen, or heard flying by, in the Huachucas, the last being observed on October 3. The earliest date on which I have noted the species in these mountains is Feb- ruary 28 (1903). Tyrannus verticalis. Arkansas Kingbird. A few were observed in the Rincons during the last week in September, but by the time we reached the Huachucas they had already departed.
