April 24, 2021 – Quite the Day

The forecast for April 24 called for rain, so I planned on spending the day inside doing chores and such. When I woke up and checked the news, the forecast indicated most of the rain would occur south of Chicago, so I headed over to Montrose for some late April birding. Good choice as it turned out to be the best day of the spring so far. The trees and shrubs were dripping with Swamp and White-throated Sparrows, Yellow-rumped Warblers, Hermit Thrushes, and Ruby-crowned Kinglets. Many of these birds were in the tops of trees feasting on swarms of small insects. I ended up with 66 species in almost four hours, and about 80 species were reported to eBird by all observers. I had multiple personal first-of-spring sightings. My highlights include

Willet – 3
White-faced Ibis – 1, first site record
Long-eared Owl – 1
Grasshopper Sparrow – 1
Northern Parula – 1
Pine Warbler – 1

The White-faced Ibis was on the protected beach early in the morning. It did not stay long. We’ve had multiple Long-eared Owls in the last week in what has been one of the best springs I can remember for them. Link to my eBird checklist for the morning below.

March 8, 2021 – Sprung is Spring

It’s axiomatic among Chicago lakefront birders that southwest winds in spring produce lots of migrants. Today, March 8, reaffirmed that maxim. I ended up with 42 species in a couple of hours of birding, including a number of new birds for the year. Large numbers of blackbirds and Canada Geese were moving on the south winds, and we had a number of unusual sightings. Best for the morning were

Greater White-fronted Geese – 27
White-winged Scoter – 1
American Woodcock – 1
Turkey Vulture – 1
Merlin – 1
Rusty Blackbird – 2

The favorable conditions will continue for at least three more days, so birding should be good at Montrose for most of the rest of the week.

Return of the Green Gunk

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?

Long-tailed Duck, October 28, 2020

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

White-winged Scoter – 1
Dunlin – 2
Greater Yellowlegs – 1
Bonaparte’s Gull – 6
Great Egret – 1, getting late
Gray Catbird – 1, getting late
Snow Bunting – 3
Vesper Sparrow – 1
Lincoln’s Sparrow – 1, getting late

Link to my eBird checklist for October 28 below, which includes more photos of the Long-tailed Duck and a few other birds.

Fall Shorebirds

Shorebird migration may be past peak but that doesn’t mean shorebird migration is over. Six species were at Montrose Beach on September 22, including

American Golden-Plover – 1 juvenile
Black-bellied Plover – 7 juveniles
Killdeer – 2
Pectoral Sandpiper – 3 juveniles
Least Sandpiper – 4
Lesser Yellowlegs – 2

A number of other shorebirds occur at this time of the year, including Dunlin (expected) and Long-billed Dowitcher (rare), and later in the fall Purple Sandpiper and Red Phalarope are possible. Link to my eBird checklist for the morning below.

Sanderlings as Grasspipers

Grasspiper – A shorebird often found in short-grass habitat, e.g., Buff-breasted Sandpiper.

More fun with Sanderlings at Montrose. On September 12 I noticed a group flying around the grassy field south of the beach. Eventually some landed and began feeding. I’m not sure I’ve seen this behavior before. Sanderlings show high fidelity to sandy beaches but like other birds can adjust their behavior and use non-typical habitat. BTW, the Montrose Beach Sanderling flock is up to 100 or so birds. This is one of the best falls for them I can remember.
