A Morning for Shorebirds


Shorebirds probed for insects in muddy areas left by receding water at the Horicon Marsh. The Dunlin is easy to identify during breeding season by the large black patch on its belly. Flocks of Dunlins spread across the Marsh on the north side of Highway 49.

Least Sandpiper

The Least Sandpiper is the smallest shorebird in the world. Small shorebirds are known as “peeps,” which gives new meaning to the sugary, marshmallow candy with the same name. The Least Sandpiper can be distinguished from the Semipalmated Sandpiper, which has dark legs, and the Pectoral Sandpiper, which has a heavily streaked breast and orange coloring at the base of the bill.

Semipalmated Plover

The Semipalmated Plover is the most common Plover seen during migration. This Plover looks similar to a Killdeer, but the Plover has a single black neck band. The Killdeer has two black neck bands. Semipalmated means the toes are webbed for only part of their length.

Barn Swallow

This Barn Swallow is masquerading as a shorebird by probing in the mud for food. Barn Swallows typically snatch insects from the air during flight. This Swallow was successful choosing an atypical menu.

Nesting Season at the Horicon Marsh

Eclipse Male Wood Ducks at the Horicon Marsh

Eclipse Male Wood Ducks

A trio of nonbreeding male Wood Ducks floats in the Horicon Marsh on a 70 degree calm Friday evening.  Wood Ducks nest from April to August. Drakes begin molting their colorful breeding plumage in July, but retain their white throat, colorful bill, and distinctive red eye.

Molting birds are flightless for 3-4 weeks. Handsome new breeding plumage will develop later this summer.

Juvenile Pied-billed Grebe

The striped juvenile Pied-billed Grebe practices diving amid short marsh reeds. Pied-billed Grebes nest from April until October and may have two broods.

Adult Pied-billed Grebe

The adult Pied-billed Grebe stays within a few yards of its young and still has its breeding plumage. The male and female look alike. They can dive up to 20 feet and stay submerged for up to 30 seconds.

Mallard with Chicks at the Horicon Marsh

Mallard with Chicks

Mallards have a long nesting season from February to September. They typically have one brood.  The ducklings are following their mother’s example, skimming the surface of the water for insects and vegetation.

Muskrat Tracks at the Horicon Marsh

Muskrat Tracks

A muskrat has been busy walking through the mud that is present along Highway 49 since the water level has been lowered. Dragging his tail creates the line between the tracks.

Spring Bird Species at the Horicon Marsh

Forster's Terns at the Horicon Marsh

Forster’s Terns

Forster’s Terns perch on last year’s cattails along Highway 49 at the Horicon Marsh. English botanist Thomas Nuttall named this tern after Johann  Reinhold Forster, a naturalist who accompanied the English explorer Captain Cook on his epic second voyage (1772-75), according to Birds of North America: Eastern Region. If you could have a bird named after you, what species would you choose? Share your choice in the comments section.

Blue-winged Teal

Male Blue-winged Teal

A pair of Blue-winged Teal swim in the water along the auto tour. They are usually skittish and fly away quickly when approached, but this pair was content to swim and eat while being photographed.

Female Blue-winged Teal at the Horicon Marsh

Female Blue-winged Teal

The female Blue-winged Teal looks similar to most other female dabbling ducks, but she is distinguished by a patch of blue on the upper wing coverts.

Fish at the Horicon Marsh


Schools of fish swim with their backs out of the water and their dorsal fins exposed. It may be related to shallow water in that area or it may be related to water temperature. Fish may swim near the surface in spring due to cooler temperatures.  In summer, they may swim deeper where it’s cooler.

Double-crested Cormorant at the Horicon Marsh

Double-crested Cormorant

The Double-crested Cormorant swims with its body submerged and its bill in the air.  It has beautiful blue eyes.

Northern Shoveler at the Horicon Marsh

Northern Shoveler

The yellow eye of the Northern Shoveler contrasts with its metallic greenish to purplish head feathers.  Flocks of Shovelers continue to swim along Highway 49.

Female Red-winged Blackbird at the Horicon Marsh

Female Red-winged Blackbird

This female Red-winged Blackbird looks nothing like its mate. They like to nest among the cattails from March to June.

Gull at the Horicon Marsh


What type of gull do you think this is? Share your thoughts in the comments area.

Bird activity is picking up at the Horicon Marsh and many species are nesting. Be careful driving on Highway 49. You may need to wait for goslings crossing the road.

Lots of Flocks

Northern Shoveler at the Horicon Marsh

Northern Shoveler

The stunning breeding plumage of the male Northern Shoveler catches your eye as you travel through the Horicon Marsh today. He is easily identified by his oversized bill, which he uses to skim across the water’s surface to find tiny crustaceans and seeds to eat. Flocks of Northern Shovelers were joined by Greater Scaups, Mallards, Blue-winged Teal, and American Coots.

Trumpeter Swan at the Horicon Marsh

Trumpeter Swan

Flocks of Tundra Swans, identified by yellow spots at the base of their bills (the lore), and Trumpeter Swans swam among the Canada Geese along Highway 49. It was a treat to drive through the auto tour which is now open to vehicles.


Gulls Just Want to Have Fun

Ring-billed Gull at the Horicon Marsh

Ring-billed Gull

Ring-billed Gulls soared together riding the wind currents over the Horicon Marsh on Sunday afternoon.  Gulls are partial migrants. Some stay in the area and some migrate to the warmer coasts in the winter.

Ring-billed Gull Watches the Surface of the Horicon Marsh

The gulls took turns hovering briefly, a few feet above the surface of the marsh, looking for fish, frogs, and insects.

Ring-billed Gull at the Horicon Marsh When they spotted a delicious morsel,  they plunged to the water, snatched their tasty treat, and took off. They often dropped their dinner and scooped it back up several times before eating it.

Tastes Like Chicken

This gull snaps up a frog from the water.

The gulls were quite vocal when they weren’t eating.

Herring Gull at the Horicon Marsh

Herring Gull

The Herring Gull is content to watch the action from the slowly dissipating ice crust. His pink legs and the red spot on his bill distinguish him from the Ring-billed Gull with its yellow legs and black band around the bill. It takes two to four years to develop this beautiful gray and white plumage accented with a black tail and white tips.



Spring is Just Around the Corner

Male (Nonbreeding) American Goldfinch at the Horicon Marsh

Male (Nonbreeding) American Goldfinch at the Horicon Marsh

A small flock of American Goldfinches flitted among the shrubs this morning at the Horicon Marsh Education and Visitor Center.  The nonbreeding plumage of the male is striking and a glimpse of its showy plumage to come this spring.  American Goldfinches breed later than most North American birds.  They wait until June when they can pluck the fluffy seeds of wild thistles to line their nests.

Canada Geese were flying and honking overhead. The Marsh is still covered in ice, but these are signs that spring is just around the corner.

The Quiet of Winter

Bahhuber Flowage Hiking Trail at the Horicon Marsh Education and Visitor Center

The Bachhuber Flowage Hiking Trail at the Horicon Marsh Education and Visitor Center

“I hide myself in the quiet white of winter and

nestle in her comforting folds of cold oblivion.”

–Terri Guillemets

Red twig dogwood branches contrast with shades of tan, walnut, and gray in the winter wetland vegetation. The absolute silence is welcoming and comforting. Winter hiking has its own unique pleasure.

Animal Tracks at the Horicon Marsh

Animal Tracks at the Horicon Marsh

Wildlife leave evidence of their activity in the slushy snow.  It was quiet on the trail, except for a few birds flitting away, as I walked by a feeder near the building. The absence of snakes makes winter hiking especially appealing.

Winter at the Horicon Marsh

The Horicon Marsh has alluring beauty in every season. Solitude and stillness captivate in winter.


Library at the Horicon Marsh

Library at the Horicon Marsh

Library at the Horicon Marsh

A cedar little library has been installed near the entrance of the Horicon Marsh Education and Visitor Center off of Highway 28.

Library Books at the Horicon Marsh

It is stocked with a variety of field guides to birds, mammals, wildflowers, trees, and insects so you can identify the wonders of nature that you find on your visit to the Horicon Marsh.  Books are available to be used while you visit the Center and area trails. Return them to the library before leaving for the next visitor to use.  The staff at the Center plan to add more children’s books from their Story at the Marsh series.

Plaque for the Library

New Bench at the Horicon Marsh

Bench and Library

Two benches were also added at the Education and Visitor Center in memory of Jerome R. through the generosity of many family members and friends.  Their kindness and thoughtfulness in attending the funeral and visitation and through sending cards was greatly appreciated by the family of Jerome R.

Plaque on Bench

Jerome R. taught science classes at Van Brunt Elementary School for 34 years.  He developed the conservation site near Horicon High School. The site included trails through woodland and wetland areas for students to study nature and the environment.  He was a Friend of the Horicon Marsh for a number of years.  He loved teaching science and he loved being in nature.

Bench at the Horicon Marsh

The family thanks the staff at the Horicon Marsh Education and Visitor Center for installing the library and benches.  Thank you to Liz Herzmann, Wildlife Conservation Educator – Wildlife Management, for her help and suggestions in coordinating the memorial.  Thank you to everyone who contributed to the memorial for Jerry R.  He would be pleased that visitors to the Marsh can enjoy educational books during their stay and rest a while on a bench overlooking an area he loved.

Birds on Ice

Rough-legged Hawk at the Horicon Marsh

Rough-legged Hawk

This Rough-legged Hawk perches high in a dead tree along Highway 49 to survey the Horicon Marsh.  Dark patches on the undersides of the wings were noticeable in flight.  The tail feathers are white at the base and dark at the ends.  These field marks, along with legs feathered to the toes, help to identify this hawk. Rough-legged Hawks nest in the arctic and visit the Marsh during the winter.  Another sign of impending winter is the layer of ice on the Marsh.  Three days ago, I drove on Highway 49 as I headed to Tom Dooley Orchards to buy some delicious apple squares from their bakery.  There were hundreds of geese, swans, and ducks swimming in the water along Highway 49.  Today, the geese are walking on the ice.

Canada Geese at the Horicon Marsh

Canada Geese

The auto tour off of Highway 49 will be closed to vehicles November 18-26 for gun deer season.  Wear blaze orange if you plan to hike.  Tom Dooley Orchards will be closed for the season on November 24th. You may want to stock your freezer with apple squares to tide yourself over until next season.

Look Alikes

Tundra Swan and Cygnet at the Horicon Marsh

Tundra Swan and Cygnet

The patch of yellow at the base of the bill is a helpful field mark to identity the Tundra Swan.  Tundra Swans nest in the arctic and stop at the Horicon Marsh during migration.  They are North America’s most numerous swan species.  Trumpeter Swans, on  the other hand, nest at the Horicon Marsh during the summer.  They lack the yellow patch at the base of the bill.

Canvasback at the Horicon Marsh


The slope of the head helps to distinguish the Canvasback from the commonly found Redhead. Male Canvasbacks have red eyes and black beaks.  Male Redheads have a rounded head, yellow eyes, and a gray beak with a black tip.  According to the Cornell Lab of Ornithology, “The species name of the Canvasback, Aythya valisineria, comes from Vallisneria americana, or wild celery, whose winter buds and rhizomes are its preferred food during the nonbreeding period.”

Green-winged Teal at the Horicon Marsh

Green-winged Teal

The Green-winged Teal is not likely to be confused with another species of duck.  They are one of the tiniest ducks.  The striking green and chestnut color on the head and neck of the male sets it apart.  They are typically found at the Horicon Marsh during the summer and during migration.

There were Hooded Mergansers, Northern Pintails, Northern Shovelers, Ruddy Ducks, and a host of other waterfowl swimming in the water along Highway 49 today.  It is a great time to visit the Horicon Marsh and see the variety of species migrating.
