On 3 February 1974 at 1400 we located a Boreal Owl (Aegolius funereus) approximately 1 km northwest of Soda Butte in the Lamar Valley of northern Yellowstone National Park, Wyoming (44° 50' N, 110° 10' W). The sighting occurred in a fairly open stand of Douglas-fir (Pseudotsuga menziesii) and Lodgepole Pine (Pinus contorta). When first sighted the owl was perched on a dead limb 2 m above the ground, but later flew 10 m to a live Douglas-fir where it perched 4 m above the ground. Seemingly undisturbed by our presence, the owl allowed us to approach within 5 m to observe and photograph it for nearly an hour (Figure 1).
