In the present specimen (1,886) there is a slight indication of an interrupted nuchal red band, as in the common Flicker, in some crimson fibres to some of the feathers about as far behind the eye as this is from the bill. A large proportion of males before us exhibit the same characteristic, some more, some less, although it generally requires careful examination for its detection. It may possibly be a characteristic of the not fully mature bird, although it occurs in two out of three male specimens.
There is a little variation in the size of the pectoral crescent and spots; the latter are sometimes rounded or oblong cordate, instead of circular. The bill varies as much as three or four tenths of an inch. The rump, usually immaculate, sometimes has a few black streaks. The extent of the red whisker varies a little. In skins from Oregon and Washington the color of the back is as described; in those from California and New Mexico it is of a grayer cast. There is little, if any, variation in the shade of red in the whiskers and quill-feathers. The head is washed on the forehead with rufous, passing into ashy on the nape.
There is not only some difference in the size of this species, in the same locality, but, as a general rule, the more southern specimens are smaller.
This species is distinct from the C. mexicanoides of Lafresnaye, though somewhat resembling it. It is, however, a smaller bird; the red of the cheeks is deeper; the whole upper part of the head and neck uniform reddish-cinnamon without any ash, in marked contrast to that on the sides of the
head. The back is strongly glossed with reddish-brown, and the black transverse bars are much more distinct, closer and broader, three or four on each feather, instead of two only. The rump and upper tail-coverts are closely barred, the centre of the former only clearer white, but even here each feather has a cordate spot of white. The spots on the flanks posteriorly exhibit a tendency to become transverse bars.
Specimens from Mount Orizaba, Mexico, are very similar to those from Oregon in color, presenting no appreciable difference. The size is, however, much less, a male measuring 10.50, wing 6.00, tail 4.60 inches, instead of 12.75, 6.75, and 5.25 respectively. While, however, the feet are smaller (tarsus 1.00 instead of 1.15), the bill is fully as large, or even larger.
Most young birds of this species have a tinge of red on top of the head, and frequently a decided nuchal crescent of red; but these are only embryonic features, and disappear with maturity.
Habits. This species, the counterpart in so many respects of the Golden-winged Woodpecker, appears to take the place of that species from the slopes of the Rocky Mountains to the Pacific, throughout western North America. Dr. Woodhouse speaks of finding it abundant along the banks of the Rio Grande. And in the fine collection belonging to the Smithsonian Institution are specimens from the Straits of Fuca, Fort Steilacoom, and Fort Vancouver, in Washington Territory, from the Columbia River, from various points in California, New Mexico, Arizona, Utah, Kansas, Nebraska, Texas, Mexico, etc. Dr. Gambel, in his Paper on the birds of California, first met with the Red-shafted Woodpecker soon after leaving New Mexico, and it continued to California, where he found it very abundant. He describes it as a remarkably shy bird, and adds that he always saw it on the margins of small creeks, where nothing grew larger than a willow-bush. Dr. Heermann also found it abundant in California. Dr. Newberry, in his Report on the zoölogy of Lieutenant Williamson’s expedition, speaks of the Red-shafted Flicker as rather a common bird in all parts of California and Oregon which his party visited. He describes many of its habits as identical with those of the Golden Flicker (C. auratus), but regards it as much the shyer bird. Dr. Cooper also mentions the fact of the great abundance of this bird along the western coast, equalling that of its closely allied cousin on the eastern side of the Mississippi. It also resembles, he adds, that bird so exactly in habits and notes that the description of one will apply with exactness to the other. It is a constant resident in Washington Territory, or at least west of the Cascade Mountains. He observed it already burrowing out holes for its nests in April, at the Straits of Fuca. About June 1 he found a nest containing seven young, nearly fledged, which already showed in the male the distinguishing red mustache. Dr. Suckley, in the same report, also says that it is extremely common in the timbered districts of Washington Territory, and adds that its habits, voice, calls, etc., are precisely similar to those of the Yellow-Hammer of the Eastern States. Mr. Nuttall, as
quoted by Mr. Audubon, states that he first came upon this bird in the narrow belt of forest which borders Laramie’s Fork of the Platte, and adds that he scarcely lost sight of it from that time until he reached the shores of the Pacific. Its manners, in all respects, are so entirely similar to those of the common species that the same description applies to both. He also regards it as the shyer bird of the two, and less frequently seen on the ground. They burrow in the oak and pine trees, and lay white eggs, after the manner of the whole family, and these eggs are in no wise distinguishable from those of the Golden-wing.
Dr. Cooper, in his Report upon the birds of California, refers to this as a common species, and found in every part of the State except the bare plains. It even frequents the low bushes, where no trees are to be seen for miles. In the middle wooded districts, and towards the north, it is much more abundant than elsewhere.
