Hello birders,

I posted a short video to CFO’s Facebook page yesterday. For you non-Facebook holdouts, it is below on YouTube.
As Ted mentioned recently, the ice is closing in at Erie Lake/Reservoir, which is near the northeast corner of Arapahoe and highway 287—trailhead on the east side of 287. So it’s fun to see the waterfowl close up. Yesterday afternoon I saw a lot of genus Aythya diving ducks—ring-necked, canvasback, and redheads—looking like a conveyor belt or carnival shooting gallery. (They also reminded me a little of participants at a CFO convention buffet line: “Line up, don’t shove, come back for seconds.”)

Is this activity about eating, pecking order, or “irrational exuberance?”
