In some instances the white on the dorsum of the northern form extends to the rump, and, occupying nearly all of the dorsal surface, forms an area very similar to that present in dorsalis, but the two may be distinguished at a glance by the hoariness and much greater amount of white exhibited by the northern bird. In many instances the barring of the sides of breast, body, and flanks (which are usually very similar in the three races), is encroached upon by the light colors in the northern bird until the under surface, as well as the back, becomes extremely light. This race appears to reach its greatest divergence from the others on the Middle and Lower Yukon. From the series of americanus before me, taken in Northern New York, and inclnding both summer and winter specimens, there appears to be very little seasonal difference of plumage except, owing to the greater amount of wearing incident to the summer season, birds taken at this time have the white tips and borders of the feathers considerably lessened by abrasion, thus appearing a little darker than winter specimens. The females and young birds possess no yellow on the crown. From Fort Liard and Fort Simpson, ou the headwaters of the Mackenzie River, extending thence north along the course of this stream and the Anderson River, and westward, covering all the wooded portions of Northern Alaska to the northern tree-limit, occurs alascensis, outnumbering by far the combined numbers of all the other woodpeckers of that region. It also extends its range south across the Alaskan Mountains, encroaching upon the range of dorsalis in the Sitkan region, and upon the island of Kadiak, whence the National Museum possesses typical specimens of this northern form....Read Less
