The 33rd annual St. Clair NWA CBC was held on January 1, 2013.

Much of the count circle is open farm field, but the extensive wetlands along the eastern side of Lake St. Clair, the lake itself as well as the lower reaches of the Thames River provide great habitat for birds, especially waterbirds, when there is just enough open water to get them more concentrated. However the current goose hunting season which extends into January has eliminated access to some of the best areas as some private hunt clubs still have paying guests.

Twelve observers covered the available area under mostly cold, cloudy conditions. Temperatures ranged from about -7C to -4C with, at times, brisk northerly winds. Snow cover in sheltered areas amounted to ~10-15 cm.

A total of 92 species was recorded, one more than previous high achieved in 2004 and 2007. Thirty-five species of waterbirds were noted, including 22 species of waterfowl. One species, Snow Goose, was observed the day before, but not on, the count day.

No new species were added, so the cumulative list beginning in 1981 remains at 137 species.

New high numbers (previous high):
Hooded Merganser--20 (9)
Bald Eagle--26 (15)
Northern Harrier--27 (26)
Merlin--3 (2)
Wild Turkey--9 (6)
Lesser Black-backed Gull--3 (1)
Glaucous Gull--16 (3)
Ruby-crowned Kinglet--2 (1)
Savannah Sparrow--20 (4)
Dark-eyed Junco--916 (611)

Tied high numbers:
Horned Grebe--1
Thayer's Gull--1
Brown Thrasher--1

Other notable species included:
Great Black-backed Gull--351, a little lower than all-time high of 372
American Crow--as usual, a very high number of crows were observed. An estimated 126,000 individuals were observed, but lower than our all time high of 159860 recorded in 2000;
Snowy Owl--one bird;

Notable misses (seen on at least half of previous counts) included:
American Wigeon
Hairy Woodpecker
Brewer's Blackbird
