The 72nd Kingston CBC was held on Sunday, December 15, 2019. The Christmas circle is centred on the tip of Garden Island and covers the entire west end of Wolfe Island and all of Kingston from Collins Bay in the west to the tip of Howe Island in the east. It extends north above the 401 to include the Little Cataraqui Creek Conservation Area and Kingston Mills.

Count day was cloudy with strong winds (W 30-40 gusting to 60 km/hr), temperatures near zero (-5°C to +2°C), no precipitation and little snow cover. Although small inland bodies of water were mostly frozen, the main lake was open and rough. A total of 60 participants spent their day in the field and 68 feeder watchers spent almost 200 hours of feeder/yard watching.

A record low of 70 species was tallied by day’s end. This was significantly below the 20 year average of 101 species and the previous lowest count of 82 in 2017. A total of 24,618 individual birds was recorded, the second lowest number in 20 years and less than half of the 20 year average of 50,093. The feeder watchers contributed 4 species that weren’t seen in the field: Sharp-shinned Hawk, Common Grackle, Pine Siskin, and Winter Wren (count week). The large number of feeder watchers likely resulted in the maintenance of average numbers of common feeder-type birds. Record or near record low numbers were found for most duck species, partly due to high winds and rough water. More specific details are listed below.

THANK YOU TO ALL OF THE SECTION LEADERS, PARTICIPANTS, LANDOWNERS AND OTHERS WHO MADE THE COUNT A SUCCESS!
