Great Black-backed Gull soaring over the Point (click to see the larger version)
March 2 could have passed for February 2 or even January 2, it was that cold and wintry. The harbor even refroze after being open for a few days. Most of the birds I saw were January or February birds but migrants are trickling in. Red-winged Blackbirds have arrived in small numbers and Horned Larks have been seen the last few days. Both of these species are bona fide and expected early spring migrants, and usually the first spring songbird migrants we see. My most unusual sighting was an adult Great Black-backed Gull soaring high over the Point. The warmer weather and south winds forecast for the next few days should bring in more migrants.
I walked over to Montrose on February 10, the first time I’ve been there since the polar air and bitter temps set in a week ago. Not surprisingly, Lake Michigan was mostly frozen, though an area of open water extended from the harbor mouth and along the shore up to the fishing pier. Hundreds of waterfowl and gulls were here, mostly Red-breasted and Common Mergansers, Common Goldeneye, and Herring Gulls. Best were a female type Black Scoter, a female Long-tailed Duck, seven Iceland Gulls, and a first cycle Lesser Black-backed Gull. A frozen Lake Michigan concentrates waterfowl in the remaining open water; these conditions are great for birding but admittedly hard on the birds. More photos are at my eBird checklist for the morning, URL below.
Herring and Ring-billed Gulls feeding in the algae mat at Montrose Beach (click to see the larger version)
The title of this post sounds like the title of a horror or monster movie — “Return of the Green Gunk!” On December 14 I was pleasantly surprised to find an extensive algae* mat at the east end of Montrose Beach. This algae mat developed when a powerful early winter storm churned up Lake Michigan and dumped large amounts of the stuff on the beach. I also noticed a group of Herring and Ring-billed Gulls picking through the algae for food. From what I could tell, and from what I’ve seen in the past, the gulls were hunting crayfish that washed in with the algae. Why does this matter? Because groups of active, feeding gulls attract more gulls that could include something unusual. Now that winter is here, there are multiple, possible rare gulls to consider. The algae could also attract a rare shorebird like a Purple Sandpiper or Red Phalarope. So if you venture out to Montrose this winter don’t forget to check the beach, and if there’s an algae mat, check it too. Once the beach gets covered in ice the algae mat won’t be accessible to gulls and shorebirds.
Only a birder gets excited about algae mats, right?

Avian activity has slowed considerably at Montrose. I’ve been topping out at about 20 species on my two hour morning visits since December 1. Things won’t improve much until late February when spring migration begins, and if the harbor and Lake Michigan freeze it will only get worse. Common Mergansers and Common Goldeneye, the two main wintering ducks, haven’t arrived yet in numbers because of the mild weather we’ve been experiencing. They’ll start to show up when it gets seriously cold. The big flocks of Red-breasted Mergansers from November have pulled out. Lake Michigan now feels lifeless and empty without them. Common Redpolls are still around but for how long is anyone’s guess. Most of the sparrows from mid-November have left, with only Dark-eyed Juncos and American Tree Sparrows remaining. Despite the doldrums, we have had a few interesting species. An adult light morph Snow Goose has been keeping company with Canada Geese. Scan any group of Canada Geese if you’re looking for it. You could also find other uncommon geese like Cackling or Greater White-fronted by looking through the Canadas. An American Black Duck, an unusual bird for Montrose, has been with Mallards, usually in the harbor. On December 4 I saw an immature Great Black-backed Gull on the public beach. As always, check the Montrose Point eBird Hotspot for current sightings.
Suggestions for Winter Birding at Montrose
I have some suggestions for winter birding at Montrose. As long as the harbor remains open it’s worth checking for waterfowl, gulls, and grebes. Long-tailed Ducks, scoters, Red-necked and Western Grebes, and several unusual gulls have been seen in the harbor in early winter. Once the harbor freezes over this won’t be an option. The hawthorns near the restroom building on the south side of the harbor are full of berries as of early December. On December 4 I had American Robins, European Starlings, and a few House Finches gorging on these berries, and something rare like a Pine Grosbeak or Bohemian Waxwing is possible while the berry supply lasts. Finally, 2020 isn’t shaping up to be a flight year for Snowy Owls but a few could still show up. The best places to look for them are the beach, Dunes, and fishing pier.
I didn’t have great expectations for October 31. The forecast called for south winds and south winds in late October never produce many birds at Montrose. Despite the unfavorable weather conditions, I was pleasantly surprised by what I did see. A couple of dead salmon washed up on Montrose Beach that attracted the attention of some Herring Gulls, which attracted the attention of a juvenile Iceland Gull. This was my first Iceland Gull of the season. Another birder alerted me to a scoter on Lake Michigan off the beach that turned out to be a Surf Scoter, another first of the season. The biggest surprise was a late Wood Thrush, the latest Wood Thrush I’ve had at Montrose, and probably anywhere else. Rounding out the list were four Common Redpolls and a couple of Snow Buntings. I tallied 37 species in three hours of birding. My eBird checklist for the morning has photos of the Iceland Gull and Surf Scoter. Follow the URL below to see it.
Long-tailed Duck (click to see the larger version)
A female Long-tailed Duck has been hanging around the fishing pier at Montrose for the last few days. On October 28 I saw her near the end of the pier on the Lake Michigan side. Long-tailed Ducks are uncommon but regular late fall through early spring visitors to Montrose.
October 28 was an interesting day with a nice mix of birds. I ended up with 49 species for about 2 hours of effort, and 60 species were reported to eBird for the day. Some of my highlights include
