觀察細節
First heard 4:57. Male and female duetting in white pine stand, uphill from trail, and uphill from roost/nest tree of last winter. Male seen in silhouette. Gave low series of hoots every ~10 seconds from ~5:00 to 5:04. Every other series, female would join in with her own, higher-pitched series of hoots. Male would lean forward and cock tail when beginning a series. At one point, female flew beneath him, and soon after, he left his perch. Duet petered out around 5:05.
