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

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

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

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

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.

 

Incredibly Rare Hammond’s Flycatcher

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.

Iowa County

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.

Yellow-breasted Chat at Brooklyn Wildlife Area

Last Sunday (June 3, 2018), I decided to sample a few areas in the southern part of the state in both Dane and Sauk Counties. The trek began early in the morning at Brooklyn State Wildlife area located just south of Madison in Dane County. Several Field Sparrows perched up on my way down the trail. I was also serenaded by the songs of Brown Thrashers, Blue-gray Gnatcatchers, and Eastern Wood-Pewees. It wasn’t until I walked about half a mile in that I heard the distinct mewing and catcalling of a YELLOW-BREASTED CHAT. I was able to locate the bird singing near the top of a nearby tree hunkered in it’s leaves.

This bird, about the size of a grosbeak, is often heard and not seen due to their elusive nature. Chats are found in areas with dense brush, such as thickets and forest openings and primarily seen in the southern part of the state. The Yellow-breasted Chat was once considered to be in the Wood Warbler family, but in 2017, this species became the only member of the Icteriidae family.

After being satisfied by a decent show from the Chat, I moved north to Sauk Prairie State Recreation Area. This area was formerly the Badger Army and Ammunition Plant, at one time the largest manufacturer of munitions in the world. The drive down the main road yielded some decent open country birds such as Eastern Meadowlarks and Clay-colored Sparrows. Most notable was a singing BELL’S VIREO not far from the entrance. After driving a few miles into the property I made it to the dense brush I was looking for. A singing WHITE-EYED VIREO sang its harsh, rapid song. Unfortunately, the bird never made an appearance before the wind picked up and activity died down.

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.

Migrants at Harrington Beach State Park

On Sunday Bri and I went to Harrington Beach State Park in Ozaukee County to do some exploring. I had never really walked Harrington Beach extensively so a lot of it was new to me. We started by heading to the beach where the high winds were causing massive whitecaps out on the lake. Many migratory water bird species were reported on the lake but today the only birds we could see were some common gulls and a small flock of Mallards.

Waves on Lake Michigan

From the beach we went up the coast and had some success looking up into the trees where Yellow-rumped Warblers and Golden-crowned Kinglets were hopping from branch to branch. Also in the trees close to the lake were several Dark-eyed Juncos.

As we moved farther inland, a different variety of birds were foraging. Hermit thrushes were hopping along the ground along with flocks of White-crowned Sparrows and White-throated Sparrows. I checked each bird I could see in hopes of finding a rare Harris’s Sparrow but had no luck.

White-throated Sparrow

We continued walking west where we found the quarry lake and followed the path around. Two Belted Kingfishers were rattling as they flew round the lake. In the soaked orange leafed branches two Yellow-bellied Sapsuckers chased each other around.

After a very pleasant walk around the quarry lake we started heading back north to the car. Along the way we found more flocks of assorted as well as a single Lincoln’s Sparrow that popped up momentarily and gave us nice looks. On some of the weeds along the trails we found our first of fall American Tree Sparrow. American Tree Sparrows along with Juncos are a natural indicator that fall is coming to a close and winter is on its way.

Near the parking lot we encountered a surge of Brown Creepers. These tiny spring and fall migrants are one of my favorite birds due to their adorable appearance. The can sometimes be seen in fall as they hop up trees but never down.

We had a great day at Harrington Beach State Park exploring the paths with sun and fall colors all around. We will definitely go back, hopefully next time there will be some more birds out on the water.

Top Six Reasons To Be Excited For Fall Migration In Wisconsin

Birders often think of spring as the most exciting time of the year. Birds are flying from the millions from the south to the north and there are rarities aplenty. However, fall can be just as exciting if not more so exciting due to some of the unique birds that come through that aren’t readily reported in spring. Here are the top six birds to look forward to this fall.

6. Buff-breasted Sandpipers

Want an excuse to go to your local sod farm? Look no further! As August draws to a close and gives way to September, Buff-breasted Sandpipers migrate through the state and wind up on beaches and in areas with short grass (like aforementioned sod farms.) Buffies make their largest push through the state in late August and early September with a few stragglers showing up later than that. Looking for Buffies represents an opportunity to go to a unique birding location. Plus, it turns out a lot of sod farm owners are really nice and will let you walk around the property if you contact them and ask nicely.

5. Sparrows

Nelson's Sparrow
Nelson’s Sparrow

Some of the state’s hardest to find sparrows make their way through Wisconsin’s fields and grasslands in autumn. The three most notable are the Nelson’s Sparrow, LeConte’s Sparrow, and Harris’s Sparrow. Nelson’s and LeConte’s Sparrows love hanging out in thick grasses and brush with both species frequenting wet grasslands and smart weed fields. They also pop up along the lake front. Harris’s Sparrows like shrubs and agricultural fields. They can sometimes be found at bird feeders. All three of these sparrows come through Wisconsin annually but are considered difficult to find.

4. Warblers

Somehow miss seeing a Tennessee Warbler the first time they came through in spring? Have no fear, pretty much the whole lot of them will be back through in the fall. While some warblers may still be in breeding plumage as they head south in late summer, by the time most of them arrive in Wisconsin they will be donning their drab, non-breeding colors. This can make identification somewhat challenging, but with a little help from field guides and online resources it isn’t too bad. Also making things a bit more difficult is that the birds won’t be singing to find a mate. This makes elusive species such as the Connecticut Warbler incredibly tough to locate and positively identify. That being said, the challenge of identifying these little birds just makes finding them more exciting.

3. Shorebirds

As is the case with warblers, shorebirds stop through Wisconsin in route to their winter destinations. Godwits, Willets, Whimbrels, and Red Knots are just some of the rarities that make an appearance in the fall. Of course, other species of more common shorebirds are also around in fairly large numbers. In addition, some shorebird species are actually a bit easier to find in fall including Black-bellied Plovers, American Golden Plovers, Baird’s Sandpipers, and Ruddy Turnstones. Check out those flooded fields and beaches to locate some cool shorebirds.

2. Migrating Hummingbirds

Rufous Hummingbird
Rufous Hummingbird

The smallest fall migrants can make a big splash in the birding community. Every fall, hummingbirds show up at hummingbird feeders and flower gardens to fuel up for their long journey. Along with the common Ruby-throated Hummingbirds are a handful of the Rufous Hummingbirds that are more rare in our state. Each year there are a number of them reported and typically one or two that stay at a particular feeder for a week or more, thus allowing people time to see them. Also making an occasional appearance are Anna’s Hummingbirds. Even rarer than the Rufous, Anna’s have been a habit of showing up later in the fall and sometimes staying as late as Thanksgiving. Keep an eye on those feeders and you just may get a glimpse of a quick moving rarity.

1. Jaegers

Parasitic Jaeger
Parasitic Jaeger

the Skua family have a habit of stealing food from the gulls on their southeastern migratory route. There are three species of jaegers that come through Wisconsin. The most common is the Parasitic Jaeger, but other potential species include Pomaraine and Long-tailed. Sounds cool right? What makes it even more of an adventure is that the happening known affectionately as “Jaeger Fest” takes place at Wisconsin Point, almost as far northwest as you can go in Wisconsin. With the point jutting out into Lake Superior, there are plenty of other interesting birds that can be seen including Sabine’s Gulls, Harris’s Sparrows, and American Avocets. If you’re interested in heading out to Jaeger Fest, feel free to check out the dates on the WSO page. There will be plenty of great birders around as well making it all the more entertaining.

Don’t be sad that summer is ending; be happy that fall migration is underway! Some excellent birds are going to be coming through and Wisconsin is about to be alive with colors and animals getting ready for winter.

Top 5 Most Annoying Things That Can Happen On Your Birding Trip

Birding is a great thing. It takes people to places they wouldn’t normally go to see and lets people get in touch with the natural world. While birding can be extremely fun, there are some annoying things that can happen when birding. Here are the top five most annoying things that happen when birding for photographers and birders alike.

5. The Bird Won’t Sit Still

We’ve all been there. The Golden-crowned Kinglet was perched out in the open, on the branch overhanging the creek. Light shimmering down illuminate the colors on the top of the head in just the perfect way. Just as you press the button to take the shot, into the brush he goes. You spend the next twenty minutes trying to get a nice picture but end up with only blurry, obscured photos, and a solid “butt-shot.” But you’re also convinced the next picture will be “the one”.

4. Empid Flycatchers

Even if you get a perfect picture of it, you still may not be able to tell exactly what species it is without hearing it call.

3. When The Bugs Are So Bad It Ruins Your Trip

It’s almost impossible to enjoy a birding trip when a million things are buzzing in your ear, dive bombing your head, and/or biting you. If you see the bird you’re looking for it’s worth it. If you don’t, you never want to go outside again.

2. YOU FORGOT YOUR SD CARD (or other piece of valuable equipment)

You finally get to your favorite shorebird spot and can see the hundreds of peeps moving around way out there. Time to get out the trusty scope. Uh oh…Why is it not in the back seat? You always double check that you have everything, but today you were so excited that you forgot! What a horrible day. (Or you just didn’t have your camera on you when that Northern Goshawk swoops in and sits for 10 minutes on the branch in front of you). No way your friends are gonna believe this one.

1. When You “Just Missed It”

Everyone’s been here before. You drive 6 hours to see a rare bird only to be told “it was just here 5 minutes ago, I’m sure it will come back”. But it never does. The group who had been watching it for the past hour is laughing and joking and having a grand old time while you sit there in silence, knowing if you’d skipped having that bowl of Honey Nut Cheerios this morning, you would have seen the dang thing. You drive home wondering “what could have been.”

Is there anything about birding that annoys you that we didn’t list? Mention it in the comments below.

 

Birds Of Lake Winnebago

We took a family trip out to the western shores of Lake Winnebago in Fond Du Lac County. Of course, we were keeping an eye out for birds.

House Finch
House Finch

When we went out in the back yard of house we were staying at we immediately started seeing birds. In the trees near the water there House Finches and a single Warbling Vireo. Foraging along the ground were House Sparrows, Chipping Sparrows, Mourning Doves, and American Robins. For a few minutes a Spotted Sandpiper also made a brief appearance on the lawn.

Warbling Vireo

Out over the water there were plenty of Ring-billed Gulls and Double-crested Cormorants. Every so often the majestic American White Pelicans flew over or sometimes even landed within 50 feet of the shore. The raspy call of the Forster’s Tern could also be heard from time to time as groups of them flew past.

P1310898
American White Pelicans

Some of the most interesting birds to watch were the many swallows swirling around our dock. To the south, Purple Martins could be heard and sometimes seen. From the north, Northern Roughed-winged Swallows flew threw, and just one dock away a colony of Barn Swallows gathered and dispersed every fifteen minutes or so. At the end of the day we were mesmerized by the swallows swooping just inches away from the water’s surface with the sunset colors in the background.

It was a decent birding day given the fact that we weren’t specifically trying to bird. We’ll see if we can find anything else interesting the rest of the week. Stay tuned.

Blue Grosbeak vs. Indigo Bunting

With summer upon us, some of the brightest colored birds in North America are nesting all across the country including the Midwest. Two of these birds that can be somewhat difficult to tell apart without knowing the field markings are the Blue Grosbeak and the Indigo Bunting. Both of these species are bright blue, frequently overlap in geographic range, and can be found around the same habitat. This means birders are likely to encounter both at some point. The good news is that there are some surefire ways to differentiate the two.

Indigo Buntin
Indigo Bunting

Size

As far as size is concerned, there is a discernible difference between a Blue Grosbeak and an Indigo Bunting. Blue Grosbeaks typically range between 15 and 16 cm while Indigo Buntings are between 12 and 13 cm. This means that in theory, an Indigo Bunting should never be as large as even a relatively small Blue Grosbeak. While it is hard to tell size on a single bird by itself, a side by side comparison shows this difference distinctly.

Blue Grosbeak
Blue Grosbeak

Range

The range of these two species differs slightly with much of it overlapping.

Blue Grosbeaks general range is as far south as Central America during the winter months and as far north as North Dakota in summer. They span from the west coast to the east coast and can be found readily in the southern states. While the Blue Grosbeak is widespread in the United States, their basic range does not typically go north of Colorado and Indiana with only a few individuals spotted annually during summer in states like Wisconsin. They do however appear farther north in the central part of the United States as they also summer in Oklahoma and the Dakotas.

Blue Grosbeak Range

Much like the Blue Grosbeak, Indigo Buntings winter as far south as Central America. This bright blue bird also inhabits most of the southern United States with the exception of parts of Arizona and Texas. It is also notable to note that the Indigo Buntings range seems to skip over western Mexico. Unlike Blue Grosbeaks, Indigo Buntings make their way much farther north in summer as they are found in every state east of Montana and even southern parts of Canada.

Indigo Bunting Range

Bill

Bill size is a solid way to differentiate between these two species. The indigo Bunting has a relatively small, conical bill while the Blue Grosbeak has a comparatively larger bill. In addition, The Indigo Bunting has a completely one colored gray/silver bill. The Blue Grosbeak often sports a two colored bill with a darker gray on the upper mandible and lighter gray on the bottom mandible.

Blue Grosbeak
Blue Grosbeak

Field Markings

Though both of these birds are a very similar shade of blue, there are some differences in pattern and coloration that go a long way in identification.

The Blue Grosbeak has a small black mask near the base of the bill going over the eye that the Indigo Bunting lacks. They also have very distinctive rusty wing bars that serve as an extremely reliable field marking. Female Blue Grosbeaks lack the deep blue of the males (instead they are a dark tan/light brown color) but still have the same rust colored wing bars.

Indigo Buntings are almost entirely blue with some of their only other coloring being a varied gray to black on their wings. They do have a very small amount of black near the base of the bill but not nearly to the degree that the Blue Grosbeak does. Females are a lighter shade of tan than the Blue Grosbeak and lack the wing bars of the Blue Grosbeak females.

Indigo Buntings
Indigo Bunting

These two species often co-exist in the same habitat and overlap readily in the United States and Mexico. Even in ranges where only one of these species would be expected. It is good to know the ways to tell them apart just in case.

Spring Green Preserve – Wisconsin’s Desert

Today Derek and I headed out to Sauk County to look for some birds, reptiles, and insects at one of the most unique environments in the state: Spring Green Preserve. Spring Green is located in the south central part of the state and is one of the most arid places in the state. “Wisconsin’s Desert” is complete with sand, cacti, and numerous flora and fauna that are found nowhere else in the state.

P1310444.JPG

We made the two hour drive and arrived a little after 7 am. We were immediately greeted by swarms of small insects buzzing around our faces. For the early part of the morning the small gnats and flies were nearly insufferable but we pressed on. We heard several loud calls coming from the Prairie as we broke the thresh hold between the parking area and the preserve. The preserve itself is relatively small with only one trail that leads from the lot into the large ridges that prevent moisture from getting to the sandy ground. One call that stood out was that of the Dickcissel. This has been a good year for the species and Spring Green is perhaps one of their greatest strongholds in Wisconsin. It seemed like every short tree and shrub had a Dickcissel on top.

P1310419
Dickcissel

If not a Dickcissel on a particular tree top it was a Lark Sparrow. Lark Sparrows can be found in other counties but they are more seldom reported. At Spring Green they are extremely numerous. This gave us a great opportunity to watch some of their behavior. The sparrows were constantly chasing each other from tree to tree and gathering large grasshoppers and other insects. There was even one Lark Sparrow that nonchalantly hopped on the trail just a few feet ahead of us gathering insects and acting oblivious to our presence.

P1310533.JPG
Lark Sparrow

One other very loud species on the Prairie was the Grasshopper Sparrow. These sparrows earned their name from their insect-like buzzing noise they make as well as the fact that they grasshoppers make up a large portion of their diet. Grasshopper Sparrows belong to a group of elusive sparrows known as Ammodramus Sparrows. This group of birds likes to skulk in tall grasses and other plants. They are often difficult to find, but these Grasshopper Sparrows perched up very nicely for us to view.

P1310387

After a while we were joined by Rob Pendergast and continued searching. By the time Rob arrived a nice breeze had picked up over the preserve and a lot of the insect activity had subsided. We walked back the same way on the trail we had paced back and forth on earlier and came across one of the local reptiles: a Blue Racer. Blue Racers are among the fastest snakes in North America. They can be found in prairies and Oak Savannas in the western half of the state. This one was lazily slithering near the trail and eventually climbed a small tree.

P1310450.JPG
Blue Racer

Also present near the same area was another quick reptile: The Prairie Racerunner. Much like the Blue Racer, these lizards have incredible speed (up to 18 mph.) We found them quickly running across the sand trail and sunning themselves on rusted sheet metal.

P1310514.JPG

As we walked the trail we picked up some other bird species that call the preserve home. An Indigo Bunting sang loudly from the largest dead tree in site and Orchard Orioles created a chorus along with Rose-Breasted Grosbeaks on both ends of the trail where more trees were growing. Many other common birds such as Mourning Doves, Robins and Blue Jays were in the area as well.

Having thoroughly searched for all avian activity in the area, we turned our attention to some unique invertebrates. Spring Green is known by a proud few for its Tiger Beetles. Nine (possibly 10) species of this small but veracious predatory insect make Spring Green their home. We were able to find three species of them. The Oblique-Lined, the Festive, and the Big Sand. They would fly and sometimes run along the path we were walking. Much like everything else we encountered, the Tiger Beetles are extremely fast movers. So fast in fact that while they run after their prey they go temporarily blind until they stop moving.

P1310501

In all, we were pleased with out day in the desert. We missed out on two rare birds that were reported recently (Blue Grosbeak and Northern Mockingbird), but seeing the other interesting birds, reptiles, and insects made the trip well worth it. It’s not everyday we get to explore such a unique ecosystem in our home state.
