The 124th Christmas Bird Count in Michigan

By John L. Trapp

Published November 08, 2024

For the fourth consecutive year, Michigan participants in the 124^th (2023-2024) CBC experienced relatively mild winter weather throughout the count period. This likely contributed to a remarkable record number of 161 species, the average of the previous 10 years being just 150 species! The number of circles sampled increased from 71 last year to 75 this year. The regional distribution of counts remains similar to previous years, with 14 in the Upper Peninsula (UP), 25 in the Northern Lower Peninsula (NLP), and 36 in the Southern Lower Peninsula (SLP). Mio (NLP) was new this year, Gwinn (UP) and Tuscola U.F.A. (SLP) each returned after one-year absences, and Whitefish Point (UP) returned after an absence of several years.

Highlights include 3 species new to Michigan CBCs (Limpkin, Hammond鈥檚 Flycatcher, European Goldfinch), 14 rarities (Ross鈥檚 Goose, Spruce Grouse, American White Pelican, Broad-winged Hawk, Lesser Yellowlegs, Sanderling, Purple Sandpiper, Dunlin, Least Sandpiper, Little Gull, Eurasian Collared-Dove, Palm Warbler, Baltimore Oriole, Hoary Redpoll), and 7 species only occasionally seen on Michigan CBCs (Blue-winged Teal, Harlequin Duck, Marsh Wren, Townsend鈥檚 Solitaire, American Pipit, Orange-crowned Warbler, Savannah Sparrow). Read on to learn additional exciting details about the results of the 124^th CBC in Michigan.
