Not sure who or where from, but this morning there was a bird circling the Safeway store at Portage and Cavalier, kakking away as it circled (reminded me of Vesper). It was too high for me to make out whether adult or chick without binocs (and don't usually take them with me when I go for groceries). Certainly wasn't expecting to see or hear a falcon. Usually there are gulls, pigeons and crows around, but this morning there wasn't another bird in sight. It headed off towards the river, out of sight.
