A Nest of Richardson's Owl Of all the pleasures which fall to lot of the Oologist in the pursuit of her favorite study it seems to me that none compare with that of taking the nests of the early breeders such as some of the owls, the Canada Jay, or the Goshawk. So tie on your snowshoes some crisp March morning and sally forth into the woods in quest of the nest of the Great Horned Owl and his relative. The Great Gray is to my mind more enjoyable than any other period of the collecting season. It signifies that the long winter is nearly over and that there is three months of good collecting ahead.

Accordingly in the early spring of 1915, I renewed my search for a nest of the American Hawk Owl which up till then had been unsuccessful and one day towards the end of March, Charlie Ritchie, a young friend of

mine told me he had found a nest in a musky, a few hundred yards from his home. On March 31st I went up to investigate and in a tamarac or spruce stub was shown an old nest of the Flicker. On rapping the stub with a stick an owl put its head out of the hole. At first I thought I had found the long sought nest of the Hawk Owl but identified it later as Richardson's Owl.

April 2nd was a fine spring day and gathering together my collecting outfit of camera, climbing irons and belt, egg box, a small hunting axe, a saw, some baling wire and a few nails I started out to take the nest. The first proceeding on arrival was to see if the bird was at home and a few raps on the stub soon brought her head to the hole as shown in the picture.

Next I cut three dry spruce poles and binding the ends together with wire, erected a tripod of such height that by climbing cross pieces nailed

to the side farthest from the nest I could use my camera and in the proper position to get a good picture at a distance of about six feet. This is the method I always use in photographing nests which cannot be snapped from the ground and are not too high up to be reached in this manner. It is especially useful for all birds which breed in cavities or in large willow bushes such as we have in Alberta.

Having made already, I climbed to the proper position on the tripod and focused my camera. A rap on the stub brought the owls head to the hold and picture. Not one was secured. Putting on my climbing irons and belt I then climbed the stub and sawed out a section from the side to expose the interior of the nest to view.

While I was doing all this work the sitting bird made no attempt to leave and I could handle the eggs under her and touch her as I pleased. The only demonstration she made was in clicking her bill, owl fashion, and lightly pecking my hand. Mrs. Richardson was one of the gentlest little birds I ever met. When I had finished cutting out the nest I climbed down the stub and mounted the tripod again and secured picture number two and then picture three after my friend succeeded in scaring the little owl from her treasures at last.

There were four freshly killed mice in the nest, three of them partly eaten and one untouched. This would seem to show that the sitting bird was fed by its mate.

The nest was about fifteen feet from the ground and the cavity about ten inches deep, lined with fine grasses, both green and dry gathered from the muskeg. There were three perfectly fresh eggs in the nest, most likely an incomplete set. In size they
