Tomorrow, Sunday May 28, is the next designated monitoring night in the National Roost Monitoring Program.
Just in case you need a reminder, watch your chimney for one hour before sunset to 1/2 hour after sunset; record the time of every entry or exit event; note the number of swifts seen during the entry and exit events. Sunset will be 9:23 PM in Winnipeg.
The remaining observation nights are June 1, June 5, and June 9.
Happy chimney-gazing!
