Evening Grosbeaks Galore! Winter Finches Arrive Sax-Zim Bog 

Winter finches have arrived in the Sax-Zim Bog! Evening Grosbeaks are abundant with lesser amounts of Pine Grosbeaks and Common Redpolls. Sparky goes on an early winter jaunt in the snowy Sax-Zim Bog in search of winter birds. A junco is an unexpected find at the Sisu feeders at the Zabin. We also stop by the Welcome Center and find a Pileated Woodpecker feasting on a deer rib cage. A flock of Bohemian Waxwings make a cameo along Nichols Lake Road. A side trip takes us to Mary Lou’s new garage and outdoor “birder lounge.” Sparky also shares details about the upcoming Tiny Bird Art online auction AND the BRRRRdathon-World’s Coldest Birdathon. Come on along!

Virtually Live 25 S2E10

In this episode of Virtually Live from the Sax-Zim Bog, Sparky Stensaas shares his favorite sightings from the last month, including FIVE SPECIES OF OWLS, MINK, BOBCAT, ERMINE & WOLF! All in the Sax-Zim Bog of northern Minnesota from early February through early March.

Encounters with FIVE different owl species in Sax-Zim are highlighted… An adorable Northern Saw-whet Owl hunts below a feeder; A Great Gray plunges into the snow and pulls up a vole; chickadees help him find a Barred Owl soaking up the sun at Fringed Gentian Bog; a Snowy Owl NOT on a power pole!; and a Northern Hawk Owl returns to the Bog and performs and preens for the camera.

Sparky also shares some ETIQUETTE for watching and enjoying Great Grays without disturbing them.

In additIon, we watch a Mink hunt for fish, see an Ermine in hunting mode and enjoy a Bobcat just sitting there.

We also make a stop at the Sax-Zim Bog Welcome Center to see what’s happening there: Pine Grosbeaks and Common Redpolls in slow motion.

And lots more!

May Birding Sax-Zim Bog Virtually Live 17 S2E2 May 8 2021

Sparky takes you along on an “early” spring birding trip in northeastern Minnesota’s Sax-Zim Bog. Only 25 degrees at the start, but the good birds warm things up…stunning male Black-and-white Warbler, lingering Evening Grosbeaks, Yellow Warbler, cooperative Merlin, and a very unexpected Great Gray Owl.

We also check in on the highlights from the Friends of Sax-Zim Bog “Things that Go Buzz, Croak, Hoot & Bump in the Night” field trip (can you say “cooperative Great Gray”!). Also a cacophony of frogs (4 species), displaying Snipe and more.

And we see how we discovered a $500 bill and a blond woman’s wig in the Bog. What?!!

You never know what surprises might accompany an episode of Virtually Live!

Every spring for the last 10 years or so, a flock of between 30 and 120 American White Pelicans have stopped over along the St. Louis River near Fond du Lac Duluth, Minnesota. A great vantage point is Chamber’s Grove Park. The pelicans are probably on their way to large breeding colonies in the far north of Minnesota or possibly Manitoba.

I made these short videos a couple years ago, but am finally getting them out into the “webosphere.”

They are fascinating creatures to just sit and watch…Enjoy!

Watch an American White Pelican swallow a very large fish in slow motion.

This one is filmed entirely with a DJI Phantom 4 Pro drone…Note how the pelicans completely ignore it.

NEW SEASON OF VIRTUALLY LIVE FROM SAX-ZIM BOG!

Virtually Live 16: Sax-Zim Bog in early Spring: Birding—S2E1 April 2021

Birding in the Sax-Zim Bog in April can often mean birding in snow…and we had snow on both mornings of shooting…April 14 & 19….but the birds are returning! In Virtually Live 16 (Season 2, Episode 1)  we search for Sandhill Cranes in the hopes of capturing video of them performing their courtship dance. Sparky finds a cooperative and cute Porcupine along Nichols Lake Road, Ring-necked Ducks on Nichols Lake, and he shares some very cool sightings from this past winter and early April—Great Gray Owl, Porcupine, River Otter, Mink.

It was just like the old-timers talk about….Flocks of geese everywhere! I hit it right again this year (thanks to eBird reports, the Minnesota Birding Facebook Group and intel from my birding buddies, Kim Risen and Steve Millard. Thanks guys!

Definitely got my much-needed dose of mega-goose migration on the prairie. The cacophony of goose cackles and swan honks is definitely worth the 8 hour round trip. The 25-35 mph winds made video and sound recording challenging but I did my best.

North Ottawa Impoundment in Grant County, Minnesota was the hot spot. Five species of geese including tens of thousands of Snow Geese, thousands of Greater White-fronted Geese, and lesser amounts of Ross’s Geese, Canada Geese and Cackling Geese. But back roads in Grant and Ottertail and Traverse counties held numerous flocks. I’d see a smudge on the horizon, throw up my binoculars and the smudge would come to life as a massive flock of geese.

Tundra Swans were also moving in impressive numbers.

I also searched for Short-eared Owls in prairie areas (SNAs, WPAs, WMAs) and did flush one but did not see any hunting.

Lately I’ve been posting everything to Facebook, Instagram and other social media, but forget to post here! This is one example. The Polar Vortex has moved on (about TWELVE days being below zero…only a few hours above zero during that entire time!) but I’m just getting around to putting Virtually Live 15 up here. So I promise to pay more attention to this blog in the upcoming year. Thanks!]

Put another log on the fire and enjoy this bitterly cool “Polar Vortex” episode of Virtually Live from Sax-Zim Bog!

Filmed over several days including the morning of February 11 with a record cold Minus-46F start to the day. Yikes!

How do our boreal birds survive this brutal weather? Sparky shares some physiological tricks our feathered fluffballs employ.

Then we flashback to warmer days and snowshoe with Sparky in Yellow-bellied Bog where he discovers an avian excavation. He then flashesback within the flashback to tell the tale of his wolf encounter in the woods.

We also visit the Welcome Center, Admiral Road feeders, Auggie’s Bogwalk at Fringed Gentian to see what birds and mammals are out and about in the below zero temps. I think you will be pleasantly surprised!

Cameos by Boreal Chickadees, Pine Grosbeaks, Northern Hawk Owl, Evening Grosbeak, redpolls and even an Ermine.

December 30, 2020

As Executive Director of Friends of Sax-Zim Bog, I sometimes have to run supplies up to the Welcome Center, and on today’s early afternoon jaunt I spotted a Coyote crossing the road a long ways ahead. I pulled over and waited, but I wasn’t too excited since on every trip to Yellowstone we seem to get our fill of “yote photos.”

I squeaked to try and get it to come back out of the woods. It did, and to my surprise the “Coyote” turned out to be a Timber Wolf! 

I knew from previous experience that they will sometimes parallel roads while hunting, so I pulled ahead slowly and stopped at a game trail that gave me a bit of a window towards the bog. And sure enough, I saw just the back of a wolf quickly move across the trail.

Now I was getting a bit more confident that I could intercept one of the rarest (or at least rarely seen) of Minnesota’s abundant wildlife. About a half mile up I found a trail I figured it would cross. It was about 15 feet wide and I quietly got out of my van. The woods were silent under the still of last nights 6 inches of snow. 

I walked about a hundred yards in and waited. Sure enough a couple minutes later the wolf appeared! But instead of simply crossing the trail and vanishing, it turned and took a few steps toward me. It couldn’t figure out what I was, which enabled me to get a minute of video and photos. I imagine it was 50 yards away. Amazing experience! Magical experience! You never know what is around any bend in Sax-Zim!

December 27, 2020

A few days ago I went to see this pale beauty! Its been on my “owl bucket list” for a long time. Especially gratifying since I searched three times for the subarctic at Springbrook Nature Center in Fridley, Minnesota a few years ago.

After a 4 hour drive from our homestead on the Wisconsin border of Minnesota, I arrived on the complete opposite side of the state on the North Dakota border. I had just about an hour before the sun set.

A wildlife photography friend had tipped me off to the location of this stunner. It had been seen on and off for a couple months. But as I began searching the numbers trees in the woods along the Red River of the North I started wondering if I would really find it.

But then there it was! On a tree I thought I had looked at on my way in. Wow! What a pale beauty! The Subarctic (or Western Taiga) subspecies of Great Horned Owl is very pale or even white with black markings. But the disc around the eyes almost always shows some color. They can be mistaken for Snowy Owls if it weren’t for this trait (and of course their feather “horns” which on Snowies are tiny and usually hidden).

This boreal subspecies occasionally may mate and nest in northwestern Minnesota. This bird appeared to be a male since it seemed smaller in size. Females are significantly larger than males.

Thanks again to Matt Sorum who found this in Clay County a couple months ago!

Video shows it coughing up a pellet, stretching, fluffing, watching a couple woodpeckers and silhouetted against the full moon.

Early August 2020, Carlton County, Minnesota

Estimating numbers of birds coming to your feeder is, of course, an inexact science. But we all know that there are FAR MORE BIRDS using your feeders than you see at anyone time.

The max I saw at my one Carlton County feeder at one time in early August was 9….and they were going through a quart every 48 hours. So by using the two methods below, I was likely hosting between 54 and 64 Rubythroats each day!

TWO METHODS for calculating hummingbirds at a feeder have been derived by hummer experts:

1. Multiply max number you see at one time by 6: This formula was arrived at by banders Nancy Newfield and Bob & Martha Sargent who arrived at this numerical factor after years of banding and color-marking hummers at feeders. Using this formula, I was feeding 54 hummers on any give day in early August.

2. Divide hummingbird nectar ounces consumed per day by 0.25: This “Consumption formula” was devised by North America’s preeminent hummingbird authority, Sheri Williamson, based on years of experience. Sheri arrived at 1/4 oz. per small hummer per day. I was going through 32 ounces in two days, so 16 ounces per day. That calculates to 64 hummers were using my single feeder each day. Crazy!

I have put Sheri’s actual blog post below: “Studies of field metabolic rates (the average rate at which an organism consumes energy as it goes about its daily life) indicate that small hummingbirds such as Black-chinned and Ruby-throated are going to need 45% to 50% of their body weight in sucrose (a.k.a. white sugar, the dominant sugar in the nectar of hummingbird flowers) to get through an ordinary day, so they would actually need 180% to 200% of their weight in a 25% sucrose solution.

A 25% solution is much stronger than most people use in their feeders. The generally recommended proportion is 1 part table sugar to 4 parts water by volume, which comes out to about 18% sugar by weight. Converting to this recipe, it would take approximately 250% to 280% of the bird’s weight in ordinary 1:4 feeder solution to meet each bird’s daily energy requirements.

So, how do you use these data to estimate numbers of feeder visitors? The simplest way is to convert grams to fluid ounces so that you can measure the volume consumed (you can even mark your feeder and estimate usage on the fly).

According to my postal scale, one fluid ounce of 1:4 sugar water weighs about 35.5 grams (approximately 20% more than its plain water counterpart). We’ll average the weight of the birds to 3.5 grams, or about 10% of the weight of a fluid ounce. Multiply that times by 265% for average consumption and we get 0.265 fluid ounce of 1:4 feeder solution per bird per day, which we’ll round down to 1/4 fluid ounce per bird per day. This multiplies out to around 32 smallish hummingbirds per 8 ounces of 1:4 sugar water, 128 per quart, and 512 per gallon. This is higher than the TFFBBB estimate, which is not surprising considering the differences between our figures for weight and consumption rates of the birds and weight/volume ratio of the sugar solution.

Of course, there are a lot of factors that can skew this already crude estimate. The amount of sugar water each bird consumes may be greatly reduced when natural nectar sources are available and greatly increased when the birds are under stress from cold, drought, courtship, fighting, nesting, and/or migration. A given volume will supply the needs of more birds if you make your feeder solution a little stronger than 1:4, as many people (myself included) do in winter and migration, and fewer if you make it a little weaker. Size figures in as well, so a given volume of sugar water will feed fewer Anna’s than Black-chinneds.”
