Mr. MacFarlane’s notes in regard to the nesting of these birds describe certain variations as to position, etc. One nest was on a ledge of a cliff of shale, and was composed of dry willow sticks, lined with pieces of rabbit skin and the hair of moose. Both parents were seen,—one on the nest, the other on a tree,—but both flew away on being approached. A second nest was in the top crotch of a tall pine on the river-bank. It was made of dry sticks, and thickly lined with reindeer hair. There were eight eggs in this nest. A third was in a tall pine, and was forty-five feet from the ground. It was constructed in a manner precisely similar to the preceding. A fourth was on the top of a tall pine, and only differed in having been lined with dry grass, moss, and a few reindeer hairs. The other nests appear to have been similarly situated and constructed. Nearly all were in high trees, built of dry sticks, and lined with dry grasses, mosses, and the hair of various quadrupeds. The maximum number of eggs was eight, their average six. Mr. MacFarlane states that the Raven is found throughout the winter in the Arctic regions, and that, though he has met with it north of latitude 69°, he has never known it to breed north of that line. He informs us that it is seldom that more than a single pair is to be seen at a time, and occasionally they may be noted singly, flying alone, or feeding on garbage. Sometimes a dead fox or wolf will attract quite a number to the spot. On one occasion he observed as many as twenty Ravens amicably associated together around the carcasses of two wolves that had been poisoned with strychnine. In many cases he has known the partaking of a poisoned animal prove fatal to them, as also the eating of bait laid for foxes and wolves. According to this same correspondent, one of these birds became almost domesticated at Fort Anderson, during February and March, 1865. At first it fed about the fort with a companion; soon after, coming alone, it grew bolder and bolder, alighted within the square, allowed itself to be closely approached, where the young dogs soon became familiar with it, and would even frolic and gambol with it, the Raven joining heartily in the sport in its own way. It was never known to attempt to injure even the smallest of the young dogs, nor did any of the dogs ever offer to annoy it. It at length came to be considered by all as an inmate of the establishment. While it seemed to have full confidence in the people of the fort, it kept at a careful distance from all Indian or Esquimaux visitors.
