Neotropic Cormorant vs. Double-crested Cormorant

Every spring, large flocks of dark-colored, long-necked birds make their way across North America: Double crested Cormorants. Due to their distinctive shape, these birds are easy to identify in the marshes and lakes that they inhabit. However, there is another cormorant species that occasionally makes its way north from central and south America that looks incredibly similar to its double-crested relative: The Neotropic Cormorant.

In most places in the United states, with the exception of some southern states, the Neotropic Cormorant is extremely uncommon. For that reason, it pays to know what to look for in order to find a rare species or simply to differentiate them from Double-crested Cormorants in states where the two species regularly overlap.

Size

The first thing to look at is the size and shape. Neotropic Cormorants are shorter and sleeker than Double-crested Cormorants with an average 61cm height, and a wingspan of 102 cm compared to the 70 to 90 cm height and 114 to 123 cm wingspan of the Double-crested Cormorant. In addition to the basic size difference, the Neotropic Cormorant’s tail will appear longer (compared to its body) than the Double-crested Cormorant’s tail. These characteristics are most noticeable in flight when directly compared to the other cormorant species but can also be seen when the birds are perched.

Lore Color

Size can be difficult to determine without a direct comparison to other nearby birds. Fortunately, there are some other field marks that can be used to distinguish these two species. First, note the lores (just above the bill, going from the eye to the bill) on the Double-crested Cormorant. Both juveniles and adults display yellow to orange colored lores. In Neotropic Cormorant, the lores are significantly darker. When comparing these two next to each other, there is actually a significant difference.

Gular

Another important area to note on these birds is the gular (which is essentially the upper throat). Both species have orange or yellowish gulars, but the shape is different depending on  the species. If you look carefully, you can see that the Neotropic Cormorant has a gular that angles toward the bill in an acute angle. The gular on the Double-crested Cormorant angles far less, and in many instances makes a 90 degree angle.

Another field mark birders regularly use to distinguish these species is the white triangular marking that lines the gular on the Neotropic cormorant. It’s very obvious in adults but less visible in juveniles.

Review

It can be really difficult to make a positive ID based on just one characteristic between these two species. For that reason, it’s best to look at all the field markings. As a whole, an adult Neotropic Cormorant will have a smaller, sleeker stature, a longer tail, dark lores, a gular that acutely angles in toward the bill, and a white triangular marking around the gular. An adult Double-crested Cormorant will be larger and blockier, have a shorter, stubbier tale, brightly colored lores, a gular that is less angled near the mouth, and no white triangle mark around the gular.

A Double-crested Cormorant can be identified by regarding these characteristics:

Larger size
Bulkier Appearance
Brightly colored lores
More obtuse angle where the gular meets the throat
Lack of white around the gular

A Neotropic Cormorant can be identified by the characteristics below

Smaller size
Sleeker appearance
Dark lores
Acute angle where the gular meets the throat
White triangle marking around the gular in adults

With these traits in mind, it becomes much easier to differentiate between these two species. We hope you found this post helpful. Be sure to like and subscribe for more ID tips, and leave a comment below if there are any specific species you would like to see an ID tips about.

Epic day of Birding in early April

Early April is the time of year when some of the most interesting migrants start their journey north to their breeding grounds. Many of these birds make stops in Wisconsin along with some that don’t belong here at all. Such is the case of the Golden-crowned Sparrow that showed up at a residence in Calumet County about a week ago.

Initially, the hour and a half drive, combined with nice weather made me disinterested in chasing it since I wanted to enjoy the temperatures outside. However, after the state parks closed ,and with a lot of time on my hands due to COVID lockdown, I decided to make the trip along with Derek.

Golden-crowned Sparrow

When we arrived at the home the sparrow had been seen at, other birders were just leaving. The bird had been visiting on and off, seemingly showing up a few times per hour. The homeowners were nice enough to let us come up their driveway and wait for the bird to appear. While we waited, we saw several species flying through the yard and foraging including Dark-eyed Juncos, Song Sparrows, Hairy, Woodpeckers, Tree Swallows, Eastern Phoebes, Chipping Sparrows, and Red-winged Blackbirds. After ten minutes or so we noticed a larger sparrow in the thickets near the back of the yard. Even with just quick glimpses we could tell that it was in fact the Golden-crowned Sparrow. Just as quickly as it appeared it was out of sight. Minutes later, it reappeared near the bird feeder just 15 feet from where we were waiting. It only stayed for about 30 seconds before vanishing. Since the Golden-crowned Sparrow is such a rare visitor to our state, we stayed longer, hoping to get one more look. Eventfully, it popped up again and this time stayed for a number of minutes, giving us incredible views.

After getting our lifer Golden-crowned Sparrow, we decided to head to Horicon Marsh in search of some other rare birds. We started on Ledge Road where a Surf Scoter had been seen over the past few days. We quickly found the beautiful breeding plumage bird very close to the road. Surf Scoters can be found every year in Wisconsin, but usually in much larger bodies of water and most typically in the great lakes.

After viewing the Scoter we followed a hot tip on some Whooping Cranes near the auto tour board walk. I had only ever seen one Whooping Crane in my life and Derek had never seen one, so we were excited about the prospect of finding them. When we got to the boardwalk, a Yellow-rumped Warbler was greeted us. Further out, Blue-winged Teals and Gadwalls floated around in the marsh water. Then, I noticed what looked like a big, white blob to the south. When I saw the white blob put it’s long, elegant head and neck up, I knew immediately what it was. I alerted Derek and we enjoyed some excellent looks at these endangered birds.

As we were looking at the cranes, we got another tip that there was a Eurasian Wigeon seen near the visitor center. We rushed there next as the sky began to darken. When we arrived, there were tons of people there seemingly walking around aimlessly, just wanting to have something to do. While keeping our distance from them, we scoured the water in hopes of finding our third rare species of the day. We located a Pied-billed Grebe, Double-crested Cormorant, Green-winged Teal, pair of Ospreys, Great Blue Heron, and first of year Purple Martin. Sadly, the Eurasian Wigeon was nowhere to be seen. We did however find a hybrid Snow Goose/Canada Goose on our way out which was interesting.

Although we were a little bummed about missing the Eurasian Wigeon, we couldn’t be too upset considering we had an excellent birding day with some great weather while we were out.

Hairy Woodpecker vs. Downy Woodpecker

Hopping up and down trees across North America are two very similar woodpecker species: the Hairy Woodpecker and the Downy Woodpecker. Both are black and white with almost identical patterns, and both can be found in the same habitat. At first glance it may seem impossible to tell these two birds apart, but upon closer inspection there are some tell tale differences that birders can use to make a positive identification.

Size

The first thing that helps to differentiate these species is size. The Hairy Woodpecker is larger than the downy with an average length of 18-26cm and a wingspan of 33-41cm. The Downy Woodpecker measures in at 14-18cm long on average and a wingspan of 25-30cm. This means that the Hairy Woodpecker is approximately one third bigger than a Downy Woodpecker and is about the size of a Red-bellied Woodpecker in size. While size isn’t always the most reliable tool when identifying a species, the difference between these two birds is fairly substantial.

Downy Woodpecker

Bill Length

The second and possibly best way to tell the Hairy Woodpecker from the Downy Woodpecker is by looking at the bill. The Hairy Woodpecker has a longer bill that is about equal in size to the length of the head. The Downy Woodpecker has a shorter more triangular bill about one third to one half the size of the length of the bird’s head. Bill size comparison is much easier than overall size comparison when there are no direct comparisons available in the field.

Field Markings

There are two field markings that can be used to separate the Hairy Woodpecker from the Downy Woodpecker. The first is a comma mark that goes from the shoulder to the breast. This marking is seen most prominently on the Hairy Woodpecker and is often not visible at all on the Downy. The second marking to look for is the black barring on the white other tail feathers of the Downy Woodpecker that the Hairy Woodpecker lacks. While at a distance these two things can be hard to spot, closer up or with optics, both field markings can be used to differentiate these two woodpeckers.

Hairy Woodpecker

Larger size
Longer bill

Downy Woodpecker

Smaller size
Short triangular bill

Although these birds have strikingly similar color patterns and behaviors, with the right knowledge they can be very easy to tell apart. We hope this post was helpful, follow our blog and give us a like of Facebook and Youtube

Harris’s Sparrow in Ozaukee County

On January 17th I heard that a Harris’s Sparrow had been seen by the bird feeders at the Mequon Nature Preserve in Ozaukee County, WI. A day later I decided to make the 50 minute trip north to see if I could find this rare bird.

The Harris’s Sparrow breeds in Northern Canada and can reach as far south as Texas in winter. Their normal range is between the Rocky Mountains and the Mississippi River but each year, a few individuals stray into other parts of the country such as Wisconsin, where a handful of reports come in each year.

With a blizzard the night before, I felt confident that the bird had stayed put and would be looking to the feeders at the preserve for food. When I arrived and got out of the car some light snow was falling and the wind made being outside unpleasant to say the least. A snow removal worker was plowing snow off the parking lot and shoveling the sidewalks and pathways. I walked around the east side of the building and a small flock of American Tree Sparrows and Dark-eyed Juncos flushed from some nearby bushes. I scanned through them, hoping to see the Harris’s among them. No luck this time. I went around to the north side where some bird feeders were. Several birds were actively feeding, including more Juncos and Tree Sparrows and some noisy House Sparrows.

I continued around the building, coming to the west side where there was one feeder and a couple of Black-capped Chickadees, but nothing else. I knew at this point it would be a waiting game.

Harris' Sparrow

I made a few more laps around the building when suddenly there was a larger flock of birds at the feeder to the west. Among the smaller birds I had already seen was one that was slightly larger. It had a black cap and white chest with a bright orange beak: It was the Harris’s Sparrow! Just as soon as it had appeared it took off across the road into the shrubs where it seemingly vanished. Feeling unsatisfied with my second-long encounter, I waited longer, thinking it would be back again at some point. As I waited, several other birds came and joined in the search.

It was nearly an hour of people with cameras and binoculars milling around and checking feeders until the sparrow returned. When it did, it stayed in the bushes near the feeder, occasionally moving around. From time to time it would fly up on some wood beams attached to the building. It gave pretty good lucks but was almost always obscured by branches and twigs.

Other birds seen were a flyby Cooper’s Hawk and a surprise flyover Glaucous Gull.

Cackling Goose vs. Canada Goose

Almost everyone is familiar with the loud and abundant Canada Goose. Even non birders can pick out the familiar brown bodied, black and white faced bird best known for it’s v-shaped migratory pattern and its reputation for being easily irritated by passers by. However, there is another bird closely resembling the Canada Goose that makes its way across North America during migration: The Cackling Goose.

The Cackling Goose looks extremely similar to the Canada Goose. So similar in fact, that it was originally listed as a Canada Goose subspecies. Eventually, it was determined that the Cackling Goose was different enough to warrant its own species distinction. There are now 7 subspecies of Canada Geese and 4 subspecies of Cackling Goose with each subspecies having subtle differences. While at first glance, the two species are tough to tell apart, there are a some diagnostic characteristics that make differentiating the Canada Goose and Cackling Goose much easier.

Size

Cackling Geese
Looking at the image, the petit stature of the 3 Cackling Geese in front of the many Canada Geese is obvious

One of the most noticeable differences between the Canada Goose and Cackling Goose is overall size. The Canada Goose is by far larger with an average length of 76-110 cm and wing span of 127-170 cm compared the Cackling Goose’s much daintier 63-65 cm length and 108-111 cm wingspan. When standing side by side the difference is obvious with the Cackling Goose being closer in size to a Mallard than to a Canada Goose. However, the issue is that a direct comparison is not always possible. In addition, larger subspecies of Cackling Goose can be close to the size of a smaller subspecies of Canada Goose. For this reason, size alone is not always reliable.

Bill

The next distinguishing feature to note is the bill. The Canada Goose’s bill is long and gently sloping to give it a more pointed appearance. The Cackling Goose’s bill is stubbier and slopes down more rapidly; giving it a more triangular appearance. The Cackling Goose’s shorter bill is one of the key features that can be diagnostic in the field even when there are no Canada Geese nearby to compare with.

Neck

Canada Geese
This image shows how deceptive size and neck length can be. Both of these birds are Canada Geese but the bird in front looks a bit smaller and is not elongating its neck. However, the bills on both birds are nearly identical.

Much like bill length, neck length is also a key feature that differs in the two species. The Canada Goose has a comparatively longer neck than the short neck of the Cackling Goose. Even when fully extended, the Cackling Goose will still appear to have a shorter neck. This feature can be slightly deceptive as Canada Geese can appear to have short necks when they are resting and length can be largely dependent of position of the bird..

Other Features

There are a few other less noticeable features that differentiate the species as well. One thing to look for is primary projection. The wing tips of the Canada Goose typically do not stretch as far beyond the rump as those of the cackling Goose. This gives the Cackling Goose a slightly more elegant appearance.

The size and shape of the head can also be used as a diagnostic tool. The Canada Goose’s head is larger and has a more gentle sloped angle from the back of the head to the front. The Cackling Goose has a smaller and more rounded head.

Review

Cackling Geese
Here is a good comparison to note all ID features of the Cackling Goose. The two birds in the middle of the image are smaller in size with stubby necks, stubby bills, rounded heads, and slightly longer primary feathers than the Canada Geese around them.

Canada Goose

Larger Size
Long pointed bill
Long neck
Shorter primary projection
Flatter sloping head

Cackling Goose

Smaller size
Short, stubby, triangular bill
Short neck
Longer primary projection
Small rounded head

Canada Goose vs. Cackling Goose can certainly be a challenging ID. Since most of the differentiating features are comparative, it can especially difficult to make an identification when there are no other birds around for perspective. With both species varying wildly in size due to many subspecies, no one characteristic should be used to disseminate the two. Instead, all characteristics together can help paint a clearer picture of which birds are Canada Geese and which are Cackling Geese.

Rare Warblers To Watch For This Spring

Just about every birder in the Midwest loves the arrival of spring migrants. During these months, no bird is more highly anticipated than warblers. These colorful and fast moving birds captivate the birding community for at least a month each year as everyone tries to gorge themselves on viewing as many of them as they can for the fleeting time they are here. While most species of warblers are easy to find during migration, there are some that are extremely rare. Some of these species are reported annually while others are only seen once or twice in a ten year span. Either way, finding one of these warblers can make even the most routine day birding into an instantly memorable day.

Black-Throated Gray Warbler

Extremely Rare

Black-throated Gray Warbler
Black-throated Gray Warbler

The Black-throated Gray warbler is aptly named for its black throat and dusky gray back is an extreme rarity in the Midwest with few individuals straying east of Colorado. At first glance, this species could be mistaken for a Black and White Warbler or a Blackpoll Warbler. Upon closer inspection, the Black-throated Gray Warbler has a distinctive yellow marking on the face near the bill. This species has been seen twice in Wisconsin since 2010 with all sightings occurring in May in either Dane or Ozaukee County. Black-throated Gray Warblers have also been seen in Minneapolis and north of Chicago. The most likely way to find one is to get out during May migration and check each black and white colored warbler very carefully.

Townsend’s Warbler

Extremely Rare

Townsend's Warbler
Townsend’s Warbler

The Townsend’s Warbler is another bird of Western North America that rarely strays out of its normal range. Their back is greenish yellow, their wings are black with two white wing bars, and their chest is yellow with black streaks. They have a dark cap, black throat, and distinctive yellow crescent shaped marking on the side of the face. Upon first glance they look similar to the much more common Black-throated Green Warbler, but with a closer look the differences are noticeable. Since 2010 there have been three instances of Townsend’s Warblers in Wisconsin. One bird seen at Pheasant Branch in Madison in May of 2014, one bird visiting a feeder in Kewaunee in December of 2016, and one interesting report of a bird landing on a boat 10 miles off-shore near Manitowoc in September of 2010. There seems to be very little pattern to the appearance of Townsend’s Warblers in our state but they do visit bird feeders so it’s possible that one could show up at a birders residence.

Prairie Warbler

Rare but Annual

Prairie Warbler
Prairie Warbler

The normal range of Prairie Warblers spans from the eastern Central America in winter all the way up to the Atlantic coast of Maine. Their visits to Wisconsin are few and far between with roughly one or two sightings each year. Males have a bright yellow underside with bold black streaking on the flanks and gray wings with a chestnut brown patch on the upper part of the back. They have a black semicircle under the eye. Females look similar but with more muted colors and a more grayish head. Prairie Warblers are not uncommon in lower Midwestern states but in Wisconsin the best place to find them is in the southeastern counties along Lake Michigan. There was one reliable Prairie Warbler present for five years straight during May Wisconsin’s South Kettle Moraine State Forest, but that bird has since moved on.

Kirtland’s Warbler

Annual and Breeding

Kirtland’s Warblers have a dark gray back with black streaks. Their throat and underside is bright yellow and they have distinct white markings directly above and below the eye. Males have a dark marking between their eye and bill while females are more drab with darker speckling on their underside. While not the most extravagant species, they are one of the rarest warbler species in North America due to their incredibly stringent habitat requirements for nesting. They require Jack Pines around 5-6 feet tall and leave the area once the pines exceed 10-15 feet. These birds winter in the Caribbean and migrate primarily to Michigan in the spring with a population also breeding in Wisconsin. Since this species is sensitive, there is little information on ebird about where to find them in Wisconsin but they do show up from time to time along their migratory path as well as in their top secret breeding grounds.

Worm-Eating Warbler

Annual and Breeding

Worm-eating Warbler
Worm-eating Warbler

The range of the Worm-eating Warbler is similar to that of the Prairie Warbler from Central America up the east coast and breeding east of Texas. This species is easily distinguished from other warbler species by its large pinkish bill and black head stripes on an otherwise buffy bird. Worm-eating Warblers live in areas with steep slopes and dense understory. They can be found in various places resembling this habitat in Wisconsin including Milwaukee, Madison, along the Mississippi River, and Devil’s Lake State Park. When trying to find this species listen for their high pitched buzzing call which sounds similar to that of a Chipping Sparrow.

Honorable Mentions

Other than the five species mentioned above, there are a few other warbler species that can be hard to find but are all expected to be reported several times a year or that breed in known locations in Wisconsin. Here is a brief listing of these species:

Connecticut Warbler

Yellow-throated Warbler

Kentucky Warbler

Cerulean Warbler

These species are always nice to find. Especially if they are found away from their expected locations.

Final Thoughts

May is truly an exciting month for birders as millions of birds are on the move. With a bevy of different habitats in Wisconsin and rare species showing being reported across the state, who knows what bird might show up next. Hopefully, some of those reading this will have success finding one of these rare species in Wisconsin to make the month of May that more special.

 

Birding Rainy Milwaukee

On a cold Thursday in May, a report came through of Willets and American Avocets at Lakeshore State Park in Milwaukee. In spite of the fact that the temperature was in the 40s and a steady rain poured over the entirety of southern Wisconsin, we decided to brave the weather and go see these annual, but still difficult to find birds.

When we arrived we could see numerous Herring Gulls dotting the grass and sand but couldn’t make out anything that looked like shorebirds. As we got closer, we noticed two dark shapes a few feet out from the beach. We were excited to see that these were American Avocets. We then noticed a group of five Willets that were tucked behind a large boulder and just now coming out. We stayed to enjoy these interesting birds for as long as we could until we were soaked to the point where we feared that our cameras would get too waterlogged.

We moved up the coast of Milwaukee to McKinley Beach. Here we found many Caspian Terns and two significantly smaller Common Terns. Also out over the water were hundreds of migrating Double-crested Cormorants.

Further north, we surveyed the area near Linwood treatment plant where we had a nice variety of sparrows including Swamp, Savannah, Song, and White-crowned. We also located Hermit Thrushes, Ruby-crowned Kinglets, Bonaparte’s Gulls, Yellow-rumped Warblers, and our first of year Black and White Warbler. Perhaps the biggest surprise was a lone male Bobolink calling from a large tree. I have had them in this location before so perhaps its a more common area for them than I realize.

Our final stop of the afternoon was Lake Park. Here we found White-crowned Sparrows, Northern Flickers, more Hermit Thrushes, and a Brown Thrasher. In the trees was a large group of warblers but the persistent rain and dark sky made them appear to be nothing more but black shadows against gray. A few of them dropped low enough for us to start distinguishing some features. The only non yellow-rumped in the group was an Orange-crowned Warbler. At this location, the most interesting bird was a Wilson’s Snipe that was feeding in some of the puddles in the grass.

Overall, for such a nasty weather day, we had a pretty good time birding. Even so, we were happy to go back home and change into some dry clothes.

Horicon Marsh in Early August

On Saturday, I met Derek up at Horicon Marsh. Lately, the best shorebird habitat has been at Horicon and some rare species have been located. One of the rarest has been the a Sharp-tailed Sandpiper that has been seen off and on for the past week. While the sandpiper didn’t make an appearance there was still plenty to see.

Horicon Marsh

When I arrived on highway 49 I saw an incredibly large number of birds on the mudflats to the south. Many were too far out to identify, but some of the closer birds turned out to be decent finds. Some notables were Wilson’s Phalaropes, Black-necked Stilts, and Short-billed Dowitchers.

Black-necked Stilt

On the north side of highway 49 were many Great Egrets and Great-blue Herons feeding on fish left behind by the drying water. Among the Egrets and Herons was a single Snowy Egret (a rare bird for the state with only a few reports each year). A few Least Sandpipers and Killdeer were also present.

Snowy Egret and Great-blue Heron

After another quick scan of the south side oh 49 yielded no new birds, Derek headed out while I continued to the Auto Tour. I parked in the Auto Tour lot and walked down Old Marsh Road. Within 50 feet of walking I noticed a Least Bittern perched up on the reeds. This was the closest I had ever been to a Least Bittern so even though they aren’t rare it was a nice surprise. Farther down the road I added Sora, Virginia Rail, and Black Tern to my day list. On the way out of the auto tour I located a juvenile Common Gallinule.

Overall, I found several year birds with the Snowy Egret being the rarest. While the Sharp-tailed Sandpiper couldn’t be found, it was still a great day to be out.

Common Redpoll vs. Hoary Redpoll

Each winter, the search for food drives birds from the north woods into areas south of their summer range. This winter migration brings many new species within view of birders who eagerly search them out. One such species that makes this journey is the Common Redpoll. Common Redpolls are small, colorful finches that eat seeds and often show up at bird feeders.

While Common Redpolls can be scarce in certain years, another Redpoll species is even harder to find: The Hoary Redpoll. Hoary Redpolls look incredibly similar to Common Redpolls and they often flock together. In fact, they look so much alike that there has been talk about lumping them together into one species. For now, however, the two remain separate, and some key identification features can help to tell them apart.

Bill

While both birds have very small, triangular-shaped bills, the bill of the Common Redpoll is slightly larger. Hoary Redpolls will have a shorter bill than a Common Redpoll that will appear stubbier and more pushed in.

Streaking

One of the most notable differences between the two species is the streaking on the  chest. Common Redpolls have chest streaking that is more defined than in Hoary Redpolls. They also have bold streaking on the flanks, along with streaking on the rump and undertail coverts, which is either absent or subtle in Hoary Redpolls. Note the differences in the photos below with the heavy streaking on the Common Redpoll (Top Left and Top Right) vs. the Hoary Redpoll’s lack of streaking (Bottom Left and Bottom Right).

 

Crown and Chest

Another distinguishing characteristic of Redpolls are their red coloring on the crown and chest. Both Common and Hoary Redpolls display bright red crowns, however the Hoary Redpoll’s crown is smaller and primarily at the front of the head, whereas the Common’s crown will extend back further. Additionally, the male Common Redpolls will have more red on their chest compared to the male Hoary Redpoll, which may have only washed out red coloration on the chest, or almost no red.

Overall Appearance

All in all, the Common Redpoll has a body coloration ranging from tan to brown, compared to the “frosted” and muted browns seen in Hoary Redpolls. The red on the breast of the males is typically more apparent in Common Redpolls, as is the red on the crown. When compared with Common Redpolls, Hoary Redpolls sometimes look like they are in black and white other than their darker red crown.

With winter approaching, these birds will start to pop up in local parks and bird feeders. Finding a Hoary Redpoll in a flock of Commons can prove a difficult task to the untrained birder. Hopefully these ID tips can help you differentiate between the two species.

Manitowoc And Sheboygan Lakefront

Yesterday Derek and I met Rob in Manitowoc to see if we could find any interesting birds out on the lake. We started out checking the impoundment where there was a surprising lack of gull diversity. The only species present were Ring-Billed Gulls. Walking out to the impoundment we saw many Mallards and two Hooded Mergansers. Upon arriving at the walkway that circles the small lagoon we looked out over the shoreline with the sun in our eyes. There were two Tern species: Caspian and Forster’s, a Great Blue Heron, and several American White Pelicans. On the far shore we were able to see some peeps. Two were Semipalmated Sandpipers and one was a Least.

Hooded Merganser

We walked around the the lagoon hopping from rock to rock to try and get a view of the birds sitting on the sand bar. Along the way we encountered high numbers of Song Sparrows. Most of the time they could be heard but not seen. We also located a few Spotted Sandpipers that would fly in front of us in order to stay a comfortable distance away.

Spotted Sandpipers

By the time we got to the east side of the impoundment many of the gulls had departed from the lagoon, as a result we continued on toward the many gulls that were sitting on the break wall. On the way there, a crowd of Barn Swallows lifted off from the grasses. The birds swirled around us and some landed on the taller, stronger stalks. Almost simultaneously someone with a dog spooked all of the gulls. Feeling a bit dejected we continued around and located two silhouetted Short-Billed Dowitchers.

Notable misses in Manitowoc were Bonaparte’s Gulls, Franklin’s Gulls, and Little Gulls that usually summer there.

Next we headed to Sheboygan where we were primarily going to check the north point. There were many birds sitting on the rock shelf just off-shore. Many of these birds were Herring and Ring-Billed Gulls but we did see some Bonaparte’s Gulls and what appeared to be a pair of first cycle Lesser Black-Backed Gulls. Two Spotted Sandpipers flew from rock to rock on the shore and on the rock island. We also noticed Double-Crested Cormorants, Caspian Terns, Forster’s Terns, and Common Terns. We once again missed out on Franklin’s Gulls at this location.

In all, we didn’t have a great day at the lake as we didn’t come up with any difficult to find birds but it was still great to be outside and get the chance to look!
