In the early part of May, 1901, vhile in Paonia, Delta coun- ty, Colorado, I heard of a nest of the XYestern Horned Owl. On the 8th we drove out there to investigate, and found the nest site in a cliff or bluff of adobe clay facing the west. The nest vas 18 or 20 feet above the base of the bluff and as far or farther below its top. As we approached the place the old bird flew away.

While there appeared no way to r.each the nest from below, it was possible to scramble to the top of the bluff above the nest. Arrived at the top, a rope, a loose fence post and a con- veni.ently placed prairie-dog hole furnished the desired com- bination. The first descent proved fruitless as far as the nest was coneern.ed, but embarrassingly fruitful in the amount of "dobe" carried to the bottom of the diff. The dry wall of dirt crumbled at he touch into dust as fine as flour, or rat- tled down in chunks at a vigorous blow. The second descent was successful in locating the nest on a shelf about six feet wide and four feet deep, sloping slightly down toward the .edge--rather insecure footing on that crumbling soil, but making the use of the camera possible. There were two young in the nest. After a snap at them in the defensive attitude which they immediately assumed, back- ing up against the adobe wall, I attempted to mov.e them into a better light, but one of them chose to flutter down from the protecting ledge. I followed and had him at my mercy. His picture shows how he f.elt about it, and how his evident temper impressed the camera. We left the young bird at the foot of the bluff, feeling certain that the parents would find it. The next day we returned and carried the other youngster home in a bag, and made a pet of him. He seemed to thrive on shreds of tough old rooster, which he refused to help him- self to. At first  placed it in his mouth, but in the end found that the most expeditous way was to take hold of thee bird's head, force open his bill, and poke the food down his throat. As he could swallow pieces of the roostes's neck an inch long, his digestion must have been good. The bird stood about twelve inches high. The body plum- age appeared to be mostly down--soft, fluffy and thick---but the wing and tail feathers were about half out of their sheaths. Ordinarily the ear tufts projected about half an inch, but some- times fully three-quarters of an inch. The feet and legs w.ere thickly covered with a yelowish or light buffy down. The whole of the body down was bar?ed, below as well as above, like the adult plumage. The body was light yellowish brown, gray tipped. The wing cov.erts were brownish yellow, with very dark bars fully a quarter of an inch wide. The pri- maries, secondaries and tail feathers were as dark as the bars Nest of the Western Horned Owl. 89 YOUNG WESTERN HORNED OWLS. 90 The Wilson Bulletin.--No. 44. of the coverts, with still darker bars. The feathers of the face were just beginning to show. During my absence the owl grew normally, and finally es- caped, only to return for more chicken, and was killed while indulging a cultivated appetite for chicken. I visited the nesting site in April of the following year. An empty egg shell proved that the nest was occupied again. Re- turning on the 13th we found the post ready set. The old bird was on the nest when I started down, but soon flew away. In the nest were three downy young, with pin feathers just be- ginning to show in the largest bird. There were also three young Pinon Jays, a Pocket Gopher (Thomomys), and the hind quarters of a cotton-tail rabbit, all food for the young. YOUNG WESTERN HORNED OWL.

The smallest one (at the left in the picture) I judged to be about ten days old, since it was ten days since I had found the shell at the base of the bluff. No opportunity offered for a further study of this interesting family.
