This last Saturday I led a walk for our members up to the top of Farm Hill to view the Chimney Swifts roosting in the Creamery chimney. It was a beautiful evening (though the weather forecast called for rain) with a clouds of fireflies drifting up from the meadow below the Test Barn. Our flock of Chimney Swifts is several score in size and takes about half an hour to roost. The birds execute a delicate aerobatic maneuver as they drop one-by-one into the chimney. For more information about these fascinating birds Cornell Labs has some good basic information, as does ChimneySwift.org.
