From Mr. MacFarlane’s notes, made from his observations in the Anderson River country, we gather that one nest was found on the ledge of a cliff of shaly mud on the banks of the Anderson River; another nest was on a pine-tree, eight or nine feet from the ground, and composed of a few dry willow-twigs and some half-decayed hay, etc. It was within two hundred yards of the river-bank. A third nest was in the midst of a small bushy branch of a pine-tree, and was ten feet from the ground. It was composed of coarse hay, lined with some of a finer quality, but was far from being well arranged. Mr. MacFarlane was confident that it had never been used before by a Crow or by any other bird. The oviduct of the female contained an egg ready to be laid. It was colored like the others, but the shell was still soft, and adhered to the fingers on being touched. In another instance the eggs were found on a ledge of shale in a cliff on the bank, without anything under them in the way of lining. He adds that they are even more abundant along the banks of the McKenzie than on the Anderson River. Mr. MacFarlane narrates that on the 25th of May an Indian in his employ found a nest placed in the midst of a pine branch, six feet from the ground, loosely made of a few dry sticks and a small quantity of coarse hay. It then contained two eggs. Both parents were seen, but when fired at were missed. On the 31st he revisited the nest, which still contained only two eggs, and again missed the birds. He again went to the nest, several days after, to secure the parents, and was much surprised to find that the eggs were gone. His first supposition was that some other person had taken them, but, after looking carefully about, he perceived both birds at a short distance; and this caused him to institute a search, which soon resulted in his finding that the eggs had been removed by them to the face of a muddy bank at least forty yards distant from the original nest. A few decayed leaves had been placed under them, but nothing else in the way of protection. A third egg had been added since his previous examination. These facts Mr. MacFarlane carefully investigated, and vouches for their entire accuracy. Another nest, containing four eggs, was on the ledge of a shaly cliff, and was composed of a very few decayed leaves placed under the eggs. Mr. R. Kennicott found a nest, June 2, 1860, in which incubation had already commenced. It was about a foot in diameter, was built against the trunk of a poplar, and its base was composed of sticks, the upper parts consisting of mosses and fragments of bark.
