The Barred of Aitkin County & the End of Winter?

Mississippi River and bridge at Palisade MN Aitkin Co MN IMG_1479Mississippi River at Palisade, Minnesota.
With temperatures predicted to be in the 50s (!) on Monday March 7th, I decided to take a cruise around Carlton and Aitkin Counties and see what I could find. The woods were still covered in snow, but the fields were pretty bare. I also included photos from March 11, 12 and 13 here. [UPDATE 3-14: We may be getting 2 to 7 inches of snow this week! Maybe the “End of Winter” title was a bit premature!]

While cruising an Aitkin County bog for Great Gray Owls, I found this very focused Barred Owl. It was about to pounce on an unseen mice or vole along the road ditch.

The Barred did indeed pounce, but alas, came up empty-taloned. No meal for this guy/gal this morning. Normally nocturnal, the Barred Owl will hunt in the daylight when very hungry…and at this time of winter, many northern critters can be fighting hunger.

IMG_1560Horned Larks [Aitkin County]
One of the first spring migrants in northern Minnesota is the early-nesting Horned Lark. Often showing up in late February or early March they are usually the first songbird migrants. Trumpeter Swans, Bald Eagles, Killdeer, American Kestrels, Canada Geese are other early movers in the Northland. Horned Larks nest in farm fields and short grass pastures.

Crex Meadows near Grantsburg, Wisconsin is a major staging area for Sandhill Cranes in spring and fall (April and October) so I thought with the early spring that maybe, possibly some may have returned. But no. The only migrants amongst the completely frozen marshes was this Canada Goose and about 30 or 40 Trumpeter Swans, some of whom had already paired up and staked out nests.

Allocapnia Winter Stonefly St. Croix River at WI 35 WI IMG_1729Winter Stonefly
On warm March days, the Winter Stoneflies (Allocapnia species) often emerge from cold, clean fast flowing creeks and rivers. They are flightless and forage atop the snow for bits of algae.

A hidden gem in northwest Wisconsin…and only a dozen miles or so from our house. The Black River tumbles for 165 vertical feet over Big Manitou Falls forming the highest waterfall in Wisconsin. It is in Pattison State Park.

March 11th was a GORGEOUS spring day and the raptors were on the move north! I tallied 1 American Kestrel, 1 Merlin, 3 Northern Harriers, 7 Bald Eagles (2 immatures and 5 adults) and 6 Rough-legged Hawks including this light morph and dark morph birds. The Rough-legs are heading back to breed in the Arctic of northern Canada.

We’ve had Wild Turkeys at our bird feeders for a number of years now…and every mid March the Tom’s start strutting their stuff. On March 10 and 11 I saw a Tom half puff up his feathers, but no full blown display..until the morning of March 12 when I took the three photos above. It is fun to watch them slowly erect their feathers when they notice a hen nearby, and then slowly strut and turn to show off their iridescent feathers and bright red wattle.

Northern Harrier with vole CR229 Sax-Zim Bog MN IMG_2020Northern Harrier with Vole [Sax-Zim Bog, MN]
Northern Harriers are back in town. These raptors are one of the earliest to return to the Sax-Zim Bog in NE Minnesota. They float over hayfields, marshes and meadows searching for mice and voles. This female has caught one. Males are a very striking white, gray and black. They were formerly called “Marsh Hawks.”

Bohemian Waxwing Wrenshall City Park crabapples Wrenshall MN IMG_1973Bohemian Waxwing [Wrenshall, MN]
One of our winter visitors from the Canadian North, the Bohemian Waxwing will soon be heading out of the area. A flock of 7 to 30 have been hanging out in my town’s city park for the last week, feasting and fueling up on crabapples.

With a blah gray sky as a background, I tried to make the photo more interesting by turning it into a “high key” image. I blew out the whites so it would almost look like the bird has been clipped from the background.

 

A Winter Drive through Carlton County

WHITE ON BLUE
On a sunny but very cold day in late February, I traveled out to western Carlton County in search of a Snowy Owl that had been reported there earlier in the month. I live in the NE corner of Carlton County just south of Duluth, Minnesota. I knew the odds of finding the owl were not in my favor but it was an excuse to see a part of the county I don’t usually traverse. The theme seemed to be “white on blue” with many white birds showing themselves (and a white church!), all on a backdrop of white snow, blue sky and deep blue shadows.

Rough-legged Hawk flying blue sky Finn Road Carlton Co MN IMG_5355A beautiful Rough-legged Hawk flew up from a field along Finn Road.
It was likely hunting voles, their favorite meal. Though they are nearly as large as a Red-tailed Hawk, they have much smaller talons and a relatively tiny beak for grabbing and eating small rodents. Red-tails on the other hand, can easily take large prey such as cottontail rabbits and so need the larger “equipment.”
This individual’s incomplete belly band tells me that this is an adult male…Females and immatures have a broad black belly band.
They nest in the arctic but move south in winter in search of daylight and small rodents. Minnesota is their “Arctic Riviera.”

Another visitor from the arctic tundra that makes the northern states its winter home is the Snow Bunting. Flocks of these “snowbirds” feed on weed seeds along roads and railroad tracks and in farm fields. This flock was foraging actively but flew every time I tried to get close. This, unfortunately for the photographer, is the norm for this species.

Hoary Redpoll and Common Redpoll flock Carlton Co MN IMG_5410HOARY SURPRISE
Surprising was a lone Hoary Redpoll feeding with a flock of Common Redpolls along a country road. Hoaries and Commons are two more species that breed in the north of Canada and Alaska but winter in northern Minnesota. They are an irruptive species (like the Rough-leg above) which means that they move south in varying numbers from year to year depending on the supply of food in the north…Alder catkins and birch seeds for redpolls, and voles for Rough-legged Hawks. We are thrilled to have so many redpolls this year!
Hoaries are much rarer, averaging 1 for every 100 Commons. Note her (males would have a pinkish breast) very frosty white coloration and tiny cone-shaped bill (compared to the longer sharper bill on the Common behind her.)

This old Finnish Lutheran church (Suomalainen Kirkko = Finnish Church) from 1915 was saved after its doors were closed. It was moved to this location near Hwy 73 and turned into a cultural center. I love the stark white and simple lines of this vernacular architectural gem.

I drove 95 miles and had a great time.
P.S. I did not find the Snowy Owl

Video of my Bobcat Encounter

Finally finished editing my video of a Bobcat in Carlton County in northern Minnesota. See the previous post for photos from this once-in-a-lifetime encounter at a friend’s cabin. I said it before, and I’ll say it again…truly a beautiful cat! Enjoy!

Pretty Kitty—Carlton County Bobcat

It is good to have a network of friends, and for many reasons—Friends you shoot with, friends who can give you critique and feedback, and friends who give you tips on wildlife locations. And my buddy Gene helped me with the latter. I think the text said something like “the bobcat came back this morning” This was monumental news! How could he state that so nonchalantly? I called him immediately and was set up on his property in a remote part of Carlton County, Minnesota the next day. A mere 25 minute drive from my house, I got there just after sunrise.
On the way up his long winding drive, a movement caught my eye. A winter-white Snowshoe Hare had hopped a few yards but was now sitting motionless. Too bad the Bobcat hadn’t seen this tasty meal. Witnessing a chase scene would have been a once-in-a-lifetime treat.

Bobcat Lynx rufus Carlton Co MN IMG_3429 1024pxAfter about 45 minutes of sitting quietly, it was an unbelievable thrill when Gene whispered, “Here she comes.” (We’ll call her “she” as her size seems small and features delicate…Plus, what a pretty face!). She cautiously slipped between the hazel brush, slinking her way towards the road-killed deer that Gene had provided.

Bobcat Lynx rufus Carlton Co MN IMG_3390 1024pxSensing her surroundings with acute hearing and smell and vision, she crept closer, occasionally stopping to sit and relax, making sure the coast was clear. In the nearly 3 hours we sat there, she came in about four times, but retreating after a few minutes.

Bobcat Lynx rufus Carlton Co MN IMG_3339 1024pxBobcats have increased in Minnesota over the last few decades. In an article titled “Bountiful Bobcats” in the Minnesota Conservation Volunteer Jan/Feb 2014, the author quotes “From the 1970s up to about 2000, bobcat population numbers were fairly low and stable, according to John Erb, furbearer biologist for the Department of Natural Resources. But starting around 2000, the bobcat population increased rapidly. It grew for about eight years and now appears to be stabilized at about 5,200 in spring and 8,200 in fall. (That’s well above the levels observed from 1977 to 1997—about 1,700 in spring and 2,300 in fall.) Erb and other wildlife managers hope to better understand the causes and potential implications of this bobcat resurgence.” See the entire article here

Snowshoe Hare Gene Letty's homestead CR104 Carlton Co MN IMG_3279Snowshoe Hare that greeted me on my way into Gene’s cabin…A rare sight!

Bobcat Lynx rufus Carlton Co MN IMG_3373 1024pxThe Volunteer article goes on to say, “An adult is roughly 3 feet long including its short, “bobbed” 4- to 7-inch tail. Adult males, or toms, can weigh more than 30 pounds and occasionally over 40. Adult females usually weigh 20 to 25 pounds.”

Bobcat Lynx rufus Carlton Co MN IMG_3414 1024pxWhy are they increasing? John Erb is the MN DNR’s furbearer biologist…”Erb suspects multiple reasons for the recent bobcat population explosion, although he stresses the need for more research to winnow out the causes. One possible factor is the changing climate. Minnesota is at the northern extent of bobcat distribution in North America. Bobcats are less efficient deep-snow predators than are Canada lynx, which have thicker fur, longer legs, and oversized paws.”

“Milder winters might be aiding survival rates, particularly for younger animals,” Erb says. “Female bobcats might also be coming through winter in better condition, so they might be having better reproductive output and survival of kittens.”

“Forest management could also be playing a role. Erb says disturbed and younger forests often provide dense cover and abundant edge habitat, which bobcats and some of their prey prefer. He believes this habitat has expanded due to increased logging that began in the mid-1980s, accelerated in the early 1990s, and continued until recent years. He points to a similar pattern of young forests, plentiful deer, and booming bobcat populations in the 1940s and ’50s, following turn-of-the-century logging, fires, and other forest disturbances.” From the article by Jacob Edson “Bountiful Bobcats” in the Minnesota Conservation Volunteer, Jan/Feb 2014

Bobcat Lynx rufus Carlton Co MN IMG_3376 1024px“Another factor that could be affecting bobcat populations is the increase in deer and turkey populations. Bobcats prey on deer, particularly fawns, and scavenge on dead deer, especially during winter.” Surprisingly, Bobcats are also able to take down adult deer.

Bobcat Lynx rufus Carlton Co MN IMG_3434 1024pxOne researcher has also noted that Fishers are declining in the core Bobcat range in Minnesota. Is it because they are competing for some of the same prey? Bobcats will also kill adult Fishers.

Bobcat Lynx rufus Carlton Co MN IMG_3528 1024pxForested parts of Minnesota may harbor one Bobcat per six to seven square miles. Lynx, which are better adapted to deep snow, replace Bobcats in the Arrowhead region.

Bobcat Lynx rufus Carlton Co MN IMG_3440 1024pxThis fact really surprised me. Did you know that Lynx on average weigh less than Bobcats? They rarely top 25 pounds while Bobcat Toms can top 40 pounds! It is the very long legs and large feet of a Lynx that gives us the impression of a larger animal.

My fat Bobcat (video and stills) Bushnell Trophy Cam


My bobcat buddy is still around. These images and video were taken with my remote Bushnell Trophy Cam trail camera in November and mid December. ALL WERE TAKEN WITHIN 100 YARDS OF OUR HOUSE! Of course we live on the north edge of Minnesota’s Nemadji River Valley with many square miles of roadless bog and wooded wilderness to the south.

What a fat and beautiful animal! If the still images taken in mid December are the same Bobcat as in the video (taken in mid November), why does this one seem so much “fatter?” It could be that it has acquired more of its denser winter coat and so appears fluffier (i.e. fatter). Or it cold be a different individual.

My dream is to someday photograph this gorgeous animal with a “real” camera from a blind. But how many frigid hours would I have to sit before getting a glimpse? And one click of the shutter might send it scampering.

Cats are cats
Note in the video how many familiar cat-like traits/behaviors this Bobcat has…the way it stretches on the log, its body posture when it eats, how it shakes its head, sharpens its claws and wags its short tail…all very feline.

What camera?
I also love how the Bobcat (and most wildlife) is unfazed by the camera and its red lights. This makes sense though since many mammals cannot see light in this spectrum. Cats and wild cats (Bobcat, Lynx, Mountain Lion, etc.) see in color, but they have difficulty distinguishing reds. “Reds appear as differing shades of gray to a cat. It is believed both dogs and cats see mainly in grays, yellows, and blues” (from wisegeek.com).

I hope she sticks around…and maybe more chicken, grouse and deer carcasses will help convince her that Skogstjarna is a good place to spend a cold winter.
