Each year, certain migratory birds in North America make the trip south to their wintering grounds. This journey takes place every year in roughly the same pattern. So much so, that one can almost plan their calendar according to the arrival and departure of a certain species. However, there is another migration that takes place in a much different way: the winter finch migration.
Winter finches reside in the northern forests of Canada during summer and often move around in fall and winter. However, they don’t migrate in the same patterns as other bird species. In fact they don’t even repeat the same pattern from one year to the next.
The term “irruption” is often used to describe mass migrations of some of these northern species into the United States. In years past, birders have noticed increased numbers of certain winter finch species (Inlcluding Crossbills, Evening Grosbeaks, Pine Siskins and more) in some winters, while in other winters, North America’s conifer forests stand untouched by these birds.
Part of the mystery of winter finches is that for the longest time, it was unclear which species would irrupt (if any) on a given year and what the cause was for these large flights of birds moving across the continent. It turns out there is actually a singular driving force to the movements of these birds: food.
The best way to predict which winter finch species are going to be moving south is by analyzing each species preferred food source in the north. In particular, many of these birds feed on conifer cones. When cone crops are low, these nomadic birds migrate to other areas in search of food. Enter the winter finch forecast.
Each year experts (originally Ron Pittaway and now Tyler Hoar of Ontario Field Ornithologists) put together a detailed picture of which northern conifer crops are high and low in Canada, and therefore which finch species are expected to irrupt and move into the United states. What is particularly interesting about these finch species is that each one seems to prefer a different type of conifer seed as its dietary staple. Thus, understanding the movements of a particular species is somewhat of a scientific art form. This report has become an annual treat that is highly anticipated by birders excited by the prospect of seeing these colorful birds dotting the winter landscape.
The winter finch forecast usually comes out in the middle of September and provides an excellent sneak preview of what to expect as far as the types of birds you’re likely to see come fall and winter. You can find this exciting report by going to the Finch Research Network , joining the finches, irruptions, and mast crops Facebook group, or by waiting until someone in your local birding community posts it.
Note: In addition to the winter finches, the forecast also includes clues to other irruptive and nomadic species too such as Red-breasted Nuthatches and Bohemian Waxwings.
On Sunday I took my friend Ashlee up to the Manitowoc lake front in search of some migrating shorebirds. Over the past week there had been multiple rare birds reported there including a Buff-breasted Sandpiper and a Red Knot. In addition, Manitowoc has some very pretty views along the lake which make it a great spot to visit even if the birds there are common.
When we arrived, there was a cool breeze blowing across the harbor and with air temperatures around 68 degrees (perfect for a September day in Wisconsin.) We walked the concrete path out over the water and before we even got to our birding spot, encountered two minks darting around the rocks catching Round Gobies. The minks must have been used to people as they made no qualms about being out in the open and even sometimes seeming to investigate the onlookers.
We continued to the end of the concrete path where we could see a lot of what appeared to be freshly dredged substrate. The peeps were out working the edges of the mounds of soil and puddles that dotted the landscape. The first birds we noticed on the mud flats were the usual Pectoral Sandpipers, Semipalmated Sandpipers, and Least Sandpipers. In addition to these birds in the foreground were Greater and Lesser Yellowlegs hanging out near the water in the back along with two American White Pelicans.
As we scoured the numerous birds feeding, we saw there were actually numerous Stilt Sandpipers and Semipalmated Plovers mixed in on the north side of the mud flats. As we looked closer, we noticed a dull gray bird that seemed different than anything else we saw there. This bird was round and stout with a stubbier bill than the nearby Stilt Sandpipers and had a faint white stripe over the eye. While it was missing it’s namesake reddish orange breeding plumage, this was in fact the Red Knot!
We watched the Red Knot for a while, getting some really nice looks at it before moving on. We decided to climb the rocks that lined the impoundment. Years ago these rocks were extremely easy to walk on as they were large and flat, but now, the lake had eroded large chunks of them away making it a bit more of an adventure. We rounded the bay where the shorebirds were and worked our way south on the rocks. Caspian Terns called overhead and Spotted Sandpipers flew from rock to rock as we walked by.
Eventually we made our way back to our original spot where most of the shorebirds were. A Great Blue Heron stood watch over the shorebirds and we found a buffy colored Baird’s Sandpiper among the peeps. The Red Knot was nowhere to be found when we checked the second time so we were very glad to have seen it the first time around.
Overall, it was an absolutely beautiful day in early September to be out birding and Ashlee and I enjoyed ourselves checking out the shorebirds and exploring Manitowoc.
Disclaimer: This article does not discuss the ethics of de-extinction. It is only meant to spark interest and debate about potential candidates.
In the natural world, there is no event more tragic than the extinction of an entire species. Since the 1960s more than 700 species of plants and animals have disappeared from the Earth, thought to never be seen again. Whereas extinction used to be finality, now there may be hope to one day see these creatures again through the process of de-extinction. De-extinction is the generation of an organism that is extinct. This process can be done through cloning, genome editing, and/or selective breeding.
While some of the most talked about animals to be brought back are large mammals such as the Tasmanian Tiger or Wooly Mammoth, some of the most realistic possibile candidates are birds. Here are the top seven birds that could potentially be brought back from extinction.
7. Great Auk
This large, penguin-like bird could be once found in the waters of the north Atlantic from the shores of Canada all the way to Western Europe. Humans are almost entirely to blame for the extinction of the Great Auk as it was hunted for its meat and down that was used for pillows. By the middle of the 16th century, this bird had been all but wiped out from the coasts of Europe. In 1835 the last colony of Great Auks was killed in Iceland on the island of Eldey for their skins, desired by museums. 78 Great Auk skins and 24 complete skeletons still exist, and cells could potentially be used for DNA extraction.
6. Labrador Duck
This sea duck was a migratory North American bird species that wintered off the coasts of New England and bred in Labrador and Quebec, Canada. This particular species seems to have already been rare at the time that Europeans arrived in the new world. As a result, not much is known about their life and habits. It is thought that harvesting of Labrador Duck eggs may have been a strong contributor to their eventual disappearance late in the 19th century. Their extinction is recent enough that specimens of this bird still exist and DNA could potentially be gathered.
5. Dusky Seaside Sparrow
The Dusky Seaside Sparrow was a Seaside Sparrow subspecies that lived in the Merritt Island salt marshes in Florida. It was known for its dark plumage and distinct song that separated it from other seaside sparrows. The cause of the Dusky Seaside Sparrow’s extinction is entirely due to habitat destruction. Merritt Island was flooded to reduce the mosquito population around the Kennedy Space Center. Later on, the marshes were drained due to highway construction. These two events destroyed much of the nesting habitat of these birds and led to their demise. The last known Dusky Seaside Sparrow died in 1987, but other subspecies still remain and could hold latent genes that could bring this bird back, or at the very least, a bird that has the same dark plumage.
4. Ivory-billed Woodpecker
One of the most legendary birds on this list, the Ivory-billed Woodpecker is presumed extinct. However, sightings in the past few decades lend credence to the idea that some individuals could still be alive somewhere deep in the wilderness. The Ivory-billed Woodpecker is/was one of the largest woodpeckers in the world and possibly went extinct due to habitat destruction. The last accepted sighting was in 1944 in Louisiana. It is something of an icon as birders and ornithologists continue to mount expeditions to capture proof of its continued existence. A better option could potentially be cloning, as its extinction was in the last century and relatives of the species, including the Pileated Woodpecker, still thrive.
3. Dodo Bird
The Dodo Bird has become synonymous with extinction. Living on the island of Mauritius off the coast of Madagascar, the Dodo was a large flightless bird that had no natural predators. This became problematic when sailors arrived and not only hunted the Dodo for food, but also brought invasive animals with them that killed Dodos and ravaged their nests. This bird went extinct sometime in the late 1600s and reports of their actual extinction date vary. With bones and some soft tissue samples remaining, the Dodo could someday make a reappearance if they are chosen as a de-extinction candidate.
2. Carolina Parakeet
Large flocks of Carolina Parakeets used to inhabit North America from New England all the way to the Mississippi River. These brightly colored and noisy birds moved and socialized in large flocks which may have partially led to their downfall. Carolina Parakeets were hunted for the feather trade and also to eliminate their numbers as they were considered to be a pest to farmers. Their social behavior made it all too easy to destroy entire flocks of birds at a time. Other causes of their extinction included habitat loss and disease. These birds essentially disappeared from the wild by the year 1904, and the last captive specimen died in 1918. There is hope, however, as DNA has been extracted from remaining skins and skeletons.
1. Passenger Pigeon
One of the most famous extinct animal species; the Passenger Pigeon, quite literally went from millions to none. At their peak, these members of the dove family spread from the Rocky Mountains, east to the Atlantic Coast. The chief cause of their rapid extinction was large-scale hunting as well as land clearing. Much like the Carolina Parakeet, the social flocking behavior of the Passenger Pigeon made it an easy target for hunters. The last Passenger Pigeon (named Martha) died in captivity in 1914. Since then, the Passenger Pigeon has become the poster-child for ecological preservation as it is proof that a species that was once extremely numerous is not impervious to extinction. It is possible that it could also be one of the flagship species to be cloned as enough DNA may exist to recreate the bird’s genome, and it has close relatives that are still alive and well (for now).
While the disappearance of any species is truly disheartening, there is hope that they may be brought back into existence. With scientists working on ways to synthesize genetic material, it seems like it’s only a matter of time before we will be able to see some of these birds in the flesh for the first time this century.
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
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.
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.
Rare but Annual
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.
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.
Annual and Breeding
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.
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:
These species are always nice to find. Especially if they are found away from their expected locations.
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.
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.
With 2019 on the horizon, a new year of birding, listing, and exploring is about to begin. However, before leaving 2018 in the year view mirror, lets take a moment to look back at some of the coolest birds that showed up during this past year. Here are the top 5 birds of 2018 in Wisconsin.
5. Tufted Duck
Difficulty to view: High
Starting the year off with a bang was a Tufted Duck that made an appearance in early January. Tufted Ducks have a large native range being found from Russia and Siberia all the way to Iceland and Northern Canada. Thee birds do show up on the east and west coast of the United States but rarely make their way inland. With this bird typically found in Eurasia it’s no wonder that it caused a stir in the Wisconsin birding community. The problem however, was that the bird was spending most of its time on the Minnesota side of the Mississippi River and placed itself in an inconvenient location for viewing. While it occasionally floated into Wisconsin waters and flew over the state, the time it did was sporadic at best. In fact, only 6 reports of this duck in Wisconsin made it to ebird.
4. Swallow-tailed Kite
Difficulty to view: Low
As summer ended, one of the coolest birds to visit Wisconsin in recent years made a visit: the Swallow-tailed Kite. This particular bird was spotted west of White River Marsh in Marquette County and was nice enough to stick around long enough for almost everyone interested in seeing it to get a view. Typically found as far north as the Southeastern United States and with a range that spans well into South America, surprisingly, it isn’t unheard of for Swallow-tailed Kites to stray north. One made an appearance in Door County, Wisconsin in 2016 and some reports of this species are as far north as Canada.
3. Clark’s Nutcracker
Difficulty to view: High
In one of the more bizarre situations in the Wisconsin birding community, a Clark’s Nutcracker was found at a private residence in the northern city of Minocqua. Native to the Western mountains of the United States and typically not straying into the Midwest, many were eager for a chance to view this bird. The problem though, was that the homeowners did not want hoards of birders and photographers descending on their house. As a result, area birders served as gatekeepers and only let a select few view the bird. The situation was irritating for many, but the bird was an interesting find nonetheless. Hopefully a more viewable member of the species is found in Wisconsin some day.
2. Sharp-tailed Sandpiper
Difficulty to view: Moderate
The Sharp-tailed Sandpiper is another extremely rare Eurasian visitor that is almost never found in the Midwest. It was found in Wisconsin’s Mecca for rare migrating shorebirds: Horicon Marsh. The Sandpiper was viewed by several people but locating it was a major task as it spotted on the mud flats of highway 49 where thousands of other shorebirds were also spending their time. Between heat shimmers, thousands of moving birds, and the target bird making inconsistent appearances, to many, this was the equivalent of finding a hay colored needle in a football field of hay stacks. Those that were able to find it were rewarded with adding a very rare species to their state lists.
1. Hammond’s Flycatcher
Difficulty to view: Low
Coming in at number one in the countdown is the Hammond’s Flycatcher. Maybe it’s because it’s the most recent rare species to visit Wisconsin, or because of it’s ease to find that it ranks number one. Either way, the Hammond’s Flycatcher showed up just in time to give Wisconsin birders an early Christmas present. Found in the rolling hills of Iowa County, this bird would come and go multiple times a day seemingly at random. Much like the Swallow-tailed Kite, almost everyone who wanted to see this bird was able to cash in on the opportunity. This was Wisconsin’s first state record of the species.
For a few days, a rare western visitor had been seen in Iowa County Wisconsin: the Hammond’s Flycatcher. The Hammond’s Flycatcher is a species of least concern in its natural range spanning from the Pacific coast of the United States to the Western portion of Nebraska. However, this species is almost never seen in the central Midwest, let alone Wisconsin. The Flycatcher had been appearing for brief windows of time and then vanishing into the thickets behind a house on a rural road. Other birders reported that once it disappeared, it would be gone for a number of hours before returning; making our timing incredibly important.
Derek and I had planned on leaving around 7:30 am and arriving at about 9:30 to give ourselves enough time to search. Yet again, our original plan was foiled by the fact that we accidentally slept in until about 9. We eventually got on the road and headed toward the small town of Avoca in hopes of relocating this elusive bird.
As we drove through the countryside passing Madison area in the process the skies changed from clear blue to cloudy with billows of fog hanging above us. We had been optimistic about finding Golden Eagles soaring over the ridges on the way to our target bird but the lack of visibility made it almost impossible to look high enough into the sky.
When we finally arrived, several other cars were parked on both shoulders of the road in front of the house, and birders were out of their cars milling about. When we parked and got out of the car, another birder walked past us and said that the Flycatcher was in the crab apple tree in the front of the yard. We excitedly picked up the pace and got eyes on the small bird fluttering low in the bushes. As we watched, other birders told us that some of them had waited more than 2 hours for the Hammond’s Flycatcher to arrive.
The Flycatcher appeared to be very lively even with it being so far out of its normal range. With a bird straying far from its migratory path there is always concern about the birds health and well-being. Especially for a bird that usually feeds on insects finding itself braving a Wisconsin winter. Nonetheless, the Hammond’s was actively feeding on something as it appeared to be hawking insects too small for us to see. It jumped and fluttered from a crabapple tree in the front yard, to a small bush, to the ground, and eventually out of sight behind a shed. We waited for ten more minutes after the bird departed but it never came back into sight.
Feeling excited to add the Hammond’s Flycatcher to our life lists, we decided to try and catch a glimpse of a Golden Eagle on the way home. Much of the fog had evaporated away and the raptors had begun taking light. We noticed a Bald Eagle flying overhead as well as another one feeding on a deer carcass. A Rough-legged Hawk was perched on a telephone pole in the distance, and we passed two American Kestrels off the highway.
Suddenly, Derek noticed a large bird soaring low to the northeast of the road. We were able to get quick pictures of it as it continued east. The bird turned out to be an adult Golden Eagle. We followed it east until it climbed over a ridge and disappeared out of sight.
In all, we were gone just over five hours and found two rare birds. The Golden Eagle is an annual but occasionally tough to find visitor. The Hammond’s Flycatcher (if accepted by the records committee) will be a state first. It was a fun day to be out in Wisconsin searching for birds.
Last week I woke up feeling the need to go birding. Admittedly, I hadn’t been birding as often this year as I would have liked. I was set to go to Madison that day to drop Derek off for a show he was playing and wanted to see what birds I could find in the area. I logged onto ebird and pulled up the ole’ year needs alert. I was horrified at what I saw. Common Loon, Snow Goose, Bonaparte’s Gull, Winter Wren?! What have I been doing this year?
With a sense of urgency, Derek and I made a stop at Tenney Park Dam on Lake Mendota and quickly located two Common Loons out in the waves. Relief rushed over me as I checked at least one ridiculous missing species off my year list. No less than five minutes later a Bonaparte’s Gull flew into view. Number two checked off the list.
Later that night I viewed my now slightly smaller needs list. I made it a goal to try and find those common species I was still missing to end the year on a high note.
A week later I crossed off Snow Goose as one turned up at Greenfield Park in West Allis. With three down I felt fueled in my quest to locate my missing common year birds. Here are the species I will be searching for the rest of the year:
Surf Scoter – Understandable
Black Scoter – Should be more to come
Canvasback – How?
Merlin – Can be tricky and viewing is often incidental
Winter Wren – Absurd
Tundra Swan – It’s like I don’t bird during migration
Barred Owl – I clearly haven’t tried
Eastern Screech Owl – I should just ask a photag
Ring-necked Pheasant – Do I even go outside?
Rusty Blackbird – Declining species, giving myself a pass
I will be looking for these species in the coming months and reporting back with my sightings. Leave a comment with the common birds you still need this year or anything else you consider a 2018 birding fail.
Disclaimer: Just to be clear, the definitions of birding success and failure depend on the individual. Don’t feel bad if you haven’t seen some of the birds I am considering common. We all share the joy of birding which in itself is a big win.
The days are shorter, the nights are colder, and everything is just a little spookier. Halloween is fast approaching, and with it come many natural representations of the holiday. Whether its bats, black cats, or pumpkins that get you in the mood for Halloween, there’s no question that this holiday is strongly tied to the flora and fauna of the fall.
Along with the traditional Halloween animals, Wisconsin plays host to several birds that could also serve as creepy additions to your Halloween. Whether it’s due to their coloring, habits, or association to darkness, these six birds embody the spirit of October’s holiday.
6. American Crow
The American Crow is one of the most intelligent and least appreciated birds in Wisconsin. They can be found in a variety of habitats and can often be seen soaring over highways and perching in dead trees. They eat a wide variety of foods and frequent garbage cans and other locations they can find discarded scraps. The American Crow is closely associated with darkness due to their preferred habitat being open fields and other places where little grows, inquisitive personalities, and dark coloration. Their caw evokes images of walking into dark woods as night falls. Their black color, desolate imagery, and cunning intelligence lands the American Crow at number 6 in the countdown.
5. Turkey Vulture
Soaring in at number five in the count down is the Turkey Vulture. Turkey Vultures feed mostly on carrion, using their extremely powerful sense of smell to locate dead animals. There is possibly no harbinger of death better known than the vulture. They are often represented in media as a sign that a person or animal is about to die as the vultures circle above in anticipation of a meal. The Turkey Vultures reddish-pink head is featherless so rotting meat doesn’t get stuck in their feathers when eating rotted flesh. This bald, skeletal looking head makes this bird look even creepier as it flies low over the landscape literally trying to smell dead meat. The Turkey Vulture’s association with death and zombie-like appearance puts it at number 5.
4. Eastern Screech Owl
The Eastern Screech Owl is one of the smallest owl species in Wisconsin. They come in two colors or “morphs,” a camouflaged gray and a brighter orange. Eastern Screech Owls roost in cavities during the day and hunt for small animals at night. They can be seen sunning themselves at entrance of nest boxes and tree cavities on sunny days. During the night, Screech Owls have a very distinctive call that is known as a whinny and trill. This horse-like screaming can be creepy if someone was unfamiliar with the sound. The Eastern Screech Owl’s orange pumpkin morph and their haunting call puts them at number 4.
3. Northern Shrike
While at first glance the Northern Shrike looks like the typical song bird, this medium sized creature, it is a nightmare to any animal smaller than itself. Northern Shrikes are North America’s only predatory song bird. The Shrike uses its hooked bill and sharp claws to feast on mammals, reptiles, amphibians, and other birds. The fact that this bird is predatory is not why it makes the list but rather the way it stores its prey. The Shrike has a gruesome habit of skewering its prey (often when it’s still alive) on wires and thorns to save for later. The Shrike’s macabre food storage and deceptively cute appearance make it a unique addition to the list.
2. Great-horned Owl
Picture this, walking alone in the silent winter woods. From behind you a soft, deep hoot comes from the tree tops. Without a sound a large shadow sweeps by and suddenly vanishes. Due to its large size and frequent vocalizations during mating season, the Great-horned Owl is one of the most frequently encountered owls in Wisconsin. Their spooky call, large wingspan, and piercing eyes have led some to hypothesize that numerous crypto zoological sightings of winged creatures in North America are actually Great-horned Owls. In addition to their large, shadowy appearance, Great-horned Owls have a creepy habit. They tend to decapitate larger prey items (usually medium sized mammals such as rabbits). They also sometimes remove the limbs and crush the bones to make the deceased creature easier to carry. A study found that 60 percent of Great-horned Owl kills end up decapitated.
1. Common Raven
Quoth the Raven nevermore, stated famed poet Edger Allen Poe. The Raven can be found in the Northern part of Wisconsin and looks very similar to the American Crow. What sets the Raven apart is its significantly larger size, thick bill, wedge shaped tail, and gruff call. The Common Raven has long been a deep rooted symbol associated with intelligence, insincerity, and sometimes evil. Much like the raptors in Jurassic Park, Ravens have been known to hunt in pairs or small groups and have been tabbed as incredibly intelligent. They have followed humans throughout history waiting to try and find an easy meal. Due to the Raven’s intimidating stature and relation to death and darkness thanks to Edger Allen Poe, it takes the top spot in our countdown of Halloween birds in Wisconsin.
Think there are other birds that could also be on this list? Leave us a comment below.
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.
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.
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.
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.
