M Goldman 1948 Douglas Squirrel Tamiasciurus hudsonicus 23 Aug Holbham Bay, Alaska 13:00 Sundrum Pen. I heard trilling and chirping within 100 yds radius in the woods. One scampered about the trunk of a 3 ft diam spruce staying about 10 feet from the ground. The dead branches, 2-3 in diam that jutted from the trunk afforded sitting perches. The squirrel displays an energetic, alert behavior. When stimulated by a quick motion of my arm, it would dash behind the trunk making a series of loud chirps that follow one another in succession. It would remain behind the tree, chip a few single chirps at perhaps a second interval then work his way from behind the trunk into my view in perhaps 3-4 quick bursts of scampering, a foot gained between steps. It would stay anywhere on a horizontal limb, on the trunk, hanging head down or head up!
