most obscuring the ground color. I found my first nest June 12, 1897, in the Huachuca Mountains at an elevation of about 9400 feet. The nest was placed in a red fir tree in the fork of a large limb, about thirty feet up and was well hidden by the surrounding foliage. The bird was away from the nest when I found it and did not make her appearance until I had three of her well incubated eggs in my mouth and was reaching for the fourth. I cut off a portion of the limb with the nest and made my way to the ground. After packing my treasures, which I was more than delighted over, I secured the female with a charge of dust shot and made haste for camp.

On June 15, 1898, I found a nest with young almost ready to fly. The nest was placed in a sugar pine near the extremity of a limb and about thirty feet from the ground; elevation about 9000 feet. The female was on the nest and as soon as I climbed the tree she uttered a note of distress which soon brought the male to the scene, where he joined her complaint. The notes of the male and the female are very much alike. Another nest found June 18, 1898, was placed near the extremity of a long slender limb in a yellow pine about fifty feet up. I watched the bird for fully half an hour before finding the nest and it was only with great difficulty and risk that I secured the set of three slightly incubated eggs. The nest was surrounded by pine needles and it could not be seen even from the tree in which it was situated until I was within three or four feet of it. The bird sat very close and did not leave the nest until I had cut off the limb on which it was placed and then she hopped about within four or five feet of me. The male was also near by and both birds kept up the usual note of alarm. The nest is a beauty, being covered with a wide brown material supposed to be bits of fur blossoms and is lined with fine rootlets.
On June 24, 1898, accompanied by a young assistant, I left camp before sunrise as I had several nests to examine four or five miles distant, and being anxious to reach my destination we just
