A Wet and Foggy Monroe, MI CBC - 15 Dec 2024

Twenty-three brave and hardy souls braved morning rains, fog, cold, and afternoon rain to participate in the 55th Monroe, MI Christmas Bird Count in conjunction with the 125th National Audubon Society Christmas Bird Count. Despite poor weather conditions we still managed a respectable 14,783 birds of 77 species. 78 if you include a count week Pileated Woodpecker!

Patricia Rydzewski, Moxie Sylvan, Tom Mulcrone and I started our day at 5 am with some owling action near Sterling State Park. Despite a heavy downpour we managed to call in a single Eastern Screech Owl that buzzed us a couple times and provided gorgeous looks under the headlamp.








We failed to find any owls inside the State Park so spent the next hour or so at Sal's Place having breakfast and drying off. We'd wait until 8 am when the sky brightened enough to see, and the rains began to subside. 

Luna Pier was our first stop of the morning. Ice covered Lake Erie with open water better than a quarter mile out. We'd count a scattering of Ring-billed and American Herring Gulls but would have to photograph fly-by flocks of Common Mergansers in order to identify them. Scoping the open water produced 10+ Bald Eagles at ice-edge and scattered small rafts of unknown ducks (likely Lesser Scaup and Common Goldeneye). A pair of Lesser Black-backed Gulls were close enough to ID.

Patricia and Moxie would then head off to cover the bottom half of Area 4 of the Monroe Count Circle while Tom and I headed north to cover the upper half. Just as we were leaving the parking lot a Cooper's Hawk was seen chasing a European Starling but failed and continued in the opposite direction. 


Otherwise the town of Luna Pier was relatively quiet with only a handful of starlings, House Sparrows and a surprising Golden-crowned Kinglet to count. 

We worked our way north to Safe Harbor Marina and found the location quiet. We did manage a few dozen American Goldfinch, Red-bellied Woodpeckers, a Northern Flicker and a nice Hairy Woodpecker in the woods along the entrance road.

Inside the marina we found the occasional Bald Eagle fly overhead, and enough ice in the canals to keep the waterfowl far away. Walking out to the berm next to Lake Erie we scoped the lake and managed to find a massive raft of Common Goldeneye (~600), Common Merganser (~400) and Lesser Scaup (~300). We would have to drive farther north to find a viewing location close enough to make a more accurate count.
Meanwhile Pat and Moxie would count 6 Red-tailed Hawks and our only American Kestrel for the area.

The four of us would meet for a quick lunch at McDonalds before heading to the DTE Monroe Power Plant for the afternoon count. There we would meet our host Eric Molnar (DTE Energy), his fiance Emily, Janet Smigielski, and Todd and Karen Palgut. We'd pile into the company van and Eric would tour us around the perimeter of the plant.

We failed to find any Black-crowned Night Herons this year. Construction on a new Security Booth is underway and is adjacent to the fence where the herons typically roost so it may have contributed to their absence.

At the Raisin River mouth we found a dozen Bald Eagles lining the trees along the shoreline and a nice raft of 100+ Hooded Mergansers. Overhead eagles were flying and providing a few pics despite the dark overcast skies.


Few ducks were on Lake Erie in front of the plant. We encountered a small raft of of Mallard, Common and Red-breasted Mergansers, Lesser Scaup and Common Goldeneye

Gulls roosted atop the coal buildings. Among the several hundred Ring-billed and American Herring Gulls we found several dozen Great Black-backed Gulls and even a pair of Lesser Black-backed Gulls

As we headed toward the warm water discharge canal we passed large holding ponds that were frozen. The morning rain put a nice sheen on the surface and provided a gorgeous backdrop for the Bald Eagles that were roosting on the water/ice. Behind them the dense steam rising from the discharge canal produced a surreal and picturesque view.










At the mouth of the warm water discharge canal we exited the van and walked the trail back toward the plant while surveying birds along the canal. This morning conditions were ripe for a heavy, dense fog over the canal so it was impossible to survey the far shore for Great Blue Herons, Great Egrets and Double-crested Cormorants known to roost there. But, we did manage to see the faint outline of a pair of American White Pelicans floating in the middle of the canal so they were a nice find. We'd find a second pair farther north along the canal.



A single tree on the opposite bank near the mouth of the canal held 9 Bald Eagles. Another 25 were scattered in the adjacent trees.


I was in search of a Great Egret as we have recorded them every year for the past 10 years. I had to walk almost a quarter mile before this guy appeared faintly on the opposite bank. The guy to the lower left is a Ring-billed Gull.


With rain steadily falling again we loaded the van and headed over to the fly-ash onsite where White-tailed Deer outnumbered birds on the berm (today). But, we headed to the backside of the discharge canal and the inlet to Bolles Harber where we found a pair of Great Egrets among several Double-crested Cormorants and Great Blue Herons. However, we would not find the 100's of GBHE or DCCO that we normally see this time of year. The fog was too heavy.



With gratitude to Eric and DTE for allowing us to survey the power plant Pat, Moxie, Tom and I headed over to Bolles Harbor to kill an hour before heading to dinner at the Michigan Bar and Grill. A half-hour spent at the rear of the parking lot next to the DTE onsite fence we failed to attract any owls. Four Dark-eyed Juncos were our first of the day, however, so we welcomed seeing them.

We then drove over to the Bolles Harbor boat launch where we spotted dozens of Canada Geese and Mallard. Knowing that this was part of Area 5 (Ann Smith, Dave Mendus, Karen Wade, Jackie Copeland) I was interested in any unusual species that we might add to their tally.

A singing Carolina Wren and a pair of Dunlin that appeared on the ice at the end of the pier would prove to be great additions to day's list.


I didn't bring the digiscoping equipment today so I had to settle for long-distant pics with the 200-600 mm lens. Luckily though, as the skies began to darken (even more) the Dunlin pair started working their way toward us so that we'd be able to get some great point-blank pics in last light.


















Twelve of us would meet for dinner at the Michigan Bar and Grill where I'd collect data sheets and stories. 

The Area 2 group of Allen Chartier, Alexa Blankenship, Erika Van Kirk and Spence Vanderhoof would report a flock of 50 American Pipits at the (former) J.R. Whiting Power Plant property. They'd refind the Hermit Thrush that Allen and I had 2 days ago, and a Ring-necked Pheasant that was alive during the morning but would not survive traffic by the end of the day...



Dennis and Kathy Rohmyer, along with Renee Stricker, would find most of the Blue Jays in the count circle (Area 3), as well as their own Ring-necked Pheasant and seven Wild Turkeys.

Ann, Dave, Karen and Jackie (Area 5) found their flock of 20 Wild Turkey at the corner of Laplaissance and E. Dunbar Roads, and would get credit for the Dunlin find. They also recorded most all of the Tundra Swans in the count circle. Photos courtesy of Karen Wade:















Todd and Karen Palgut, Justin Labadie and Bobby Irwin covered Area 6 and Sterling State Park. A pair of Surf Scoters, a Killdeer and 2 Saw-Whet Owls were reported. They also seemed to have the bulk of the American Robin flock in the count circle.

Shout-out to Larry Ludwig for covering Area 7 by himself while Bob Pettit recovers from recent medical issues. His highlight was a Red-shouldered Hawk that is always welcomed during the CBC season.

John Flora and Dan Schwab split Area 8 and got to contend with almost 1000 European Starling and the count circle population of House Finch. Another flock of Wild Turkey was a nice consolation.

Below are totals for each area and for the Monroe, MI CBC as a whole. Once again I'm grateful to everyone who participated, especially Dr. Linda Psalmonds who offered to provide a count near the Senior Citizen home in town. Your contributions help to maintain this count circle for its 55th season and the NAS's 125th season, the longest-running Citizen Science Project in US history.

I will add any photos submitted by participants as they arrive:

Pre-CBC Scouting - 13 Dec 2024

With the Monroe, MI CBC just 2 days away I had the opportunity to do a bit of scouting inside the count circle. Allen Chartier and I agreed to meet to walk the Lake Erie shoreline down to the Woodtick Peninsula. So before meeting him at 8 am I decided to try for a bit of owling at Sterling State Park beforehand.

I was up at 4:30 am and fed the kitties. I then grabbed the flash and flashlights and set up the Sony a1 and 200-600mm lens. I had to check last year's blog post on using the flash setup to successfully photograph owls and got that set up. At a little after 5 am I left the house and headed out the door. Skies were clear and temps were at 10F. Luckily there was no wind. It was still very cold.

I was on I-75 and N. Huron River Drive when I realized that I had forgotten my binoculars. So I had to turn around and head back home. I would not be back on the road to after 5:30 am and would not reach the state park until after 6 am.

I stopped on Waterworks Rd. just outside the park and tried for Saw-Whet Owls in the woodlot just south of the houses on the corner. No luck. I then tried for Eastern Screech Owl and had a reply within minutes of playing their call. 

I had a bit of trouble focusing on the owl as it flew in and landed across the road. The lens was on 600 mm so I was too magnified. My initial attempts to photograph were meant with soft images. Once I got the lens back to 100-200 mm I had better luck focusing and got a few images. The flash got a few fast exposures but then went dark. Luckily the little owl was fairly cooperative and gave me good lucks as I struggled to get the flashlights and focus sharp (it would turn out that my headband was on the bright LEDs instead of the flashlight that would've given me a brighter subject to focus on).






After a few frames I let the little guy go and tried for Long-eared Owls. No luck, so I continued on into the park.

I then parked behind the boat launch and walked into the tiny woodlot next to the berm. With no luck with Saw-Whets I tried the Eastern Screech Owl call again. I had a faint reply and managed to see it fly in and land in the tree nearby. Again, I had a bit of struggle focusing on the bird but managed a few pics from about 20' away. It didn't stick around so I tried for Long-eared Owls, then Great Horned Owls with no luck.


I then headed down to the south end of the park where the Saw-Whets were seen last year. I had no luck with any owls from this location.

I would then head over to McDonalds for a quick breakfast then head down to Erie Road to meet Allen at 8 am. We walked the beach south about 2 miles in the morning sunrise and luckily found the lack of wind giving us a comfortable walk. Ice was on Lake Erie out a quarter mile so any birds/ducks/geese were just specks on the horizon.

We would manage to see several Bald Eagles, Carolina Wren, Downy Woodpecker, Black-capped Chickadees, a Northern Flicker and American Tree Sparrows. Otherwise it was fairly quiet. We'd be done by 10 am and I would head home for lunch.

55th Monroe, MI Christmas Bird Count is Sunday, 15 December 2024

Sunday, December 15, 2024 will mark the 55th Annual Monroe, Michigan Christmas Bird Count that will coincide with the 125th National Audubon Society Christmas Bird Count.

Information regarding details of the count circle, protocol, history, etc. can be found in the links on the right of this page.

Participants will be asked to report their numbers (including mileage, time in field, field conditions) to their Area Leader, who will then compile numbers and submit to me.

Area Leaders are asked to use the supplied tally sheets for each Area; this makes it easier for me to get results into the master spreadsheet.

If a bird is seen in your Area that is not on the tally sheet then it will need some documentation (photos preferred). The tally sheets have been prepared based on 50-years of data so if its not listed it hasn't been seen before in your Area.

If you are interested in participating please drop me a line at jerry.jourdan@gmail.com

We will meet afterward at the Michigan Grill (formerly MI Bar and Grill) at 5 pm to tally results. 

Thanks, and

Stay safe!

Results of the 124th MI CBC (2023) - 05 Nov 2024

From John Trapp, Regional Editor of CBC:

The 124th Christmas Bird Count in Michigan
By John L. Trapp

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 124
th 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,

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 winterseason report for the UP; there are 5 previous Michigan winter-season reports in the eBird

In closing, I wish to extend a heartfelt thank you to the 63 compilers and more than 1200
participants whose dedication made this statewide summary possible. 

One topic I've never addressed in my annual CBC summaries is the regional distribution of MIchigan's wintering birds. In the following paragraphs, I've taken a stab at doing that using data from the 2023-2024 CBC. I may make this a regular component of my annual summaries. What do you think?

RELATIVE REGIONAL ABUNDANCES OF MICHIGAN’S WINTERING BIRDS

 

THE RESULTS:

CBC data (2023-2024) reveal that few if any species are distributed in equal abundance from north to south across the state of Michigan. Looking at 46 relatively abundant species, 13 reached peak relative abundance in the UP (Wild Turkey, Bald Eagle, Herring Gull, Rock Pigeon, Common Raven, Black-capped Chickadee, Red-breasted Nuthatch, Bohemian Waxwing, Cedar Waxwing, Red Crossbill, Common Redpoll, Pine Siskin, and American Goldfinch), 7 in the NLP (Canada Goose, Redhead, Common Goldeneye, Common Merganser, Mourning Dove, Blue Jay, and Snow Bunting), and 26 in the SLP (Mute Swan, Tundra Swan, American Black Duck, Mallard, Northern Shoveler, Canvasback, Ring-necked Duck, Bufflehead, Hooded Merganser, Red-breasted Merganser, Double-crested Cormorant, Sandhill Crane, Ring-billed Gull, Red-bellied Woodpecker, Downy Woodpecker, American Crow, Tufted Titmouse, White-breasted Nuthatch, Eastern Bluebird, American Robin, European Starling, American Tree Sparrow, Dark-eyed Junco, Northern Cardinal, House Finch, and House Sparrow).

 

For a description of the steps taken to derive these results, read THE PROCESS that follows. If you want to see all the gory details, check out the attached EXCEL file.

 

THE PROCESS:

Step 1: Identify the 11 most abundant species in each region based on the number of individuals (combining all regions, this step resulted in 21 species statewide).

 

Step 2: Calculate the abundance of each species identified in Step 1 relative to the 6th most abundant species in each region. The 6th most abundant species were: UP (Mallard), NLP (American Crow), SLP (Dark-eyed Junco).

 

Step 3: Identify the region in which each of the species identified in Step 1 achieves peak relative abundance (bold-faced and highlighted in YELLOW). These 21 species are the SUPER ABUNDANT.

 

Step 4: In each region, add all other species whose abundance relative to the 6th most abundant species is at least 10% (combining all regions, this step added another 25 species, bringing the total to 46).

 

Step 5: Calculate the abundance of each species added in Step 4 relative to the 6th most abundant species in each region.

 

Step 6: Identify the region in which each of the species added in Step 4 achieves peak relative abundance (highlighted in ORANGE). These 25 species are the MODERATELY ABUNDANT.
