The following summary of the 123rd Audubon Christmas Bird Count was prepared by John Trapp:The 123
rd Christmas Bird Count in Michigan
By John L. Trapp
This summary is dedicated to the memories of former Christmas Bird Count (CBC) regional
editor Raymond J. “Ray” Adams Jr. (1945-2022: https://tinyurl.com/477jvvr2) and long-time
compilers Frank Apsey (1949-2022: https://tinyurl.com/4u2ntvuv; Sturgeon Point), Monica
“Birdie” Essenmacher (1952-2022: https://tinyurl.com/22c57rw3; Huron County and Tuscola
U.F.A.), and Steven “Ranger Steve” Mueller (1950-2022: https://tinyurl.com/yk7m7c7n; Grand
Rapids). Michigan field ornithologists owe a big debt of gratitude to each of these individuals.
For the third year in a row, Michigan participants in the 123rd (2022-2023) CBC experienced
relatively mild winter weather throughout the period of the count. The impact of the weather on
the birds and the ability of observers to detect the birds present is beyond my ability to divine.
What is known, however, is that more individuals (642,599 vs 554,817) of fewer species (146 vs
158) were seen this year than last and that new, rare, or occasional species made up a smaller
percentage of the species total (6.8% vs 15.2%).
The 71 circles sampled this year had a 94.7%
similarity with last year’s 75; the regional distribution of counts remains little changed from
previous years, with 12 in the Upper Peninsula (UP), 24 in the Northern Lower Peninsula (NLP),
and 36 in the Southern Lower Peninsula (SLP).
Highlights included two new species (Southern
Lapwing—new to North America and Lark Sparrow—new to Michigan), five rarities (Ross’s
Goose, American White Pelican, Purple Sandpiper, American Three-toed Woodpecker,
Lincoln’s Sparrow), and three species only occasionally seen on Michigan CBCs (Blue-winged
Teal, American Pipit, Eastern Meadowlark). Read on to learn additional exciting details about
the results of the 123rd CBC in Michigan. Enjoy!
Michigan’s Early-Winter Avifauna: In the decade prior to the 123rd CBC, 139 species were
reported on Michigan CBCs in 7 or more years; these “expected” or “regular” species are
deemed the core of Michigan’s early-winter avifauna. Nine species seen in 5 or 6 of the
previous 10 years are considered “borderline” or “occasional” members of the earlywinter avifauna. Forty-eight species documented in 1-4 of the previous 10 years are
“rare” or “extremely rare” and are not to be expected with any degree of probability in
any given year.
Two New Species (reported on a Michigan CBC for the first time):
• Southern Lapwing – 1 at Oscoda (NLP) on 12/21; a bird present at that locality since late
June 2023 and viewed and photographed (last on 12/22) by multitudes is a first summer,
fall, winter and CBC record for Michigan, the United States, and North America. This
occurrence is currently under review by the Michigan Bird Records Committee.
• Lark Sparrow – 1 photographed at Marquette (UP) on 12/17 is the second (and latest)
December record for Michigan in the eBird database, the previous record also being in
the UP.
Five Rarely Seen Species (reported in fewer than 5 of the previous 10 years):

14, 21

• Lincoln’s Sparrow – 1 at Western Macomb County (SLP) – 3, 14, 21
