Dr. Coues gives this bird as rare and probably accidental in the immediate vicinity of Fort Whipple, but as a common bird in the valleys of the Gila and of the Lower Colorado, where it has the local name of Suwarrow, or Saguaro, on account of its partiality for the large cactuses, with the juice of which plant its plumage is often found stained.
Dr. Cooper found this Woodpecker abundant in winter at Fort Mohave, when they feed chiefly on the berries of the mistletoe, and are very shy. He rarely saw them pecking at the trees, but they seemed to depend for a living on insects, which were numerous on the foliage during the spring. They have a loud note of alarm, strikingly similar to that of the Phainopepla nitens, which associated with them in the mistletoe-boughs.
About the 25th of March he found them preparing their nests in burrows near the dead tops of trees, none of them, so far as he saw, being accessible. By the last of May they had entirely deserted the mistletoe, and were probably feeding their young on insects.

Gen. Char. Bill about equal to the head; broader than high at the base, but becoming compressed immediately anterior to the commencement of the gonys. Culmen and gonys with a moderately decided angular ridge; both decidedly curved from the very base. A rather prominent acute ridge commences at the base of the mandible, a little below the ridge of the culmen, and proceeds but a short distance anterior to the nostrils (about one third of the way), when it sinks down, and the bill is then smooth. The lateral outlines are gently concave from the basal two thirds; then gently convex to the tip, which does not exhibit any abrupt bevelling. Nostrils open, broadly oval; not concealed by the feathers, nor entirely basal. Fork of chin less than half lower jaw. The outer pair of toes equal. Wings long, broad; lengthened. Tail-feathers broad, with lengthened points.
The species all have the back black, without any spots or streaks anywhere.
