A Swift Night Out is a continent-wide effort to raise awareness about and encourage interest in Chimney Swifts and Vaux’s Swifts (in the West).
As summer draws to a close and the swifts have finished raising their young, these fascinating aerial acro- bats begin to congregate in communal roosts prior to their migration in the fall. Some roosts may consist of an extended family group of a half a dozen birds or so, but the larger sites can host hundreds or even thousands of swifts!
Here is how it works: Keep your eyes to the skies at dusk in late July and watch for areas where swifts are feeding. Look for a tall shaft, chimney, or similar structure to locate where chimney swifts go to roost in your area.
On one night (Friday, Saturday or Sunday) over the second weekend of August and/or September observe the roost starting about 30 minutes before sunset and estimate the number of swifts that enter. After the last swift enters the structure, please fill out the on-line reporting form.
