The 124th Christmas Bird Count in Michigan

 Audubon > News Read More [[{“value”:”

For the fourth consecutive year, Michigan participants in the 124th (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’s Flycatcher, European Goldfinch), 14 rarities (Ross’s 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’s Solitaire, American Pipit, Orange-crowned Warbler, Savannah Sparrow). Read on to learn additional exciting details about the results of the 124th CBC in Michigan.

Three New Species (i.e., reported on a Michigan CBC for the first time):

·         Limpkin – 1 on 12/31 at Tuscola U.F.A. (SLP—in the Quanicassee State Wildlife Area, where present since 10/6) was the last of an unprecedentedly massive influx into the state beginning early July and peaking September-October, with eBird reports from an amazing 10 counties.

·         Hammond’s Flycatcher – 1 discovered by Mike Mahler and 4 others at New Buffalo (SLP—in Warren Woods State Park) on 12/19 and seen by 4 other parties that same day, ultimately remained through 12/23 and was reported—and thoroughly documented with scores of photographs—on 66 eBird checklists; a new state record for Michigan.

·         European Goldfinch – 1 photographed at a feeder at Au Train on 12/17 is a first winter-season report for the UP; there are 5 previous Michigan winter-season reports in the eBird database, all from the SLP.
