Like thousands of others, I've fallen in love with Jackie and Shadow, the bald-eagle couple who nest in a Jeffrey pine high above Big Bear Lake, California. One of the scattered joys of this grim year has been watching Jackie and Shadow raise two plucky eaglets, Sunny and Gizmo. (Local schoolkids chose the names.) Expertly positioned cameras allow fans to observe the family at close range. This video features several conversational exchanges between Jackie and Shadow, who are empty-nesters for the moment, Sunny and Gizmo having gone off on their Grand Journeys, as aquiline lingo has it. Eaglesong can't be described as conventionally musical, but it has a distinctive contour, designed, perhaps, to cut across large distances. Something remarkable happens at 10:45. A nocturnal marital chat seems to prompt a howl from a solitary coyote, whereupon a veritable oratorio of coyote calls ensues, echoing in the valley around the lake. Beneath it all is a pedal point of crickets.
