Virtually Live 17: S2E2 May 8, 2021

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!

Pelican Antics & Pelicans from the Air: Two short films

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.

Virtually Live 16—Porcupines, Otters, Mink, Sandhill Cranes and more…”Early” spring in Sax-Zim Bog

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.

Goose-a-Palooza! FIVE species of goose migrating through western Minnesota—March 19-20

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.

Ice Eagles: Bald Eagles fishing a frozen Mississippi River: Canon R5 Wildlife Photography Shooting with Sparky

During the icy grip of the February 2021 Polar Vortex cold snap, Sparky travels to the mostly frozen Mississippi River of southeast Minnesota and southwest Wisconsin to photograph Bald Eagles fishing open spots close to shore. He also looks for Golden Eagles inland in Houston and Winona Counties in Minnesota.

Bitter windchills means frozen toes and fingers, but the Canon R5 does an amazing job of autofocus while shooting super slow motion (4K 120fps) video of the eagles.

A trip to Old Frontenac Cemetery nets Sparky’s first photos and videos of Tufted Titmouse in Minnesota.

The trip ends at Crex Meadows near Grantsburg Wisconsin where an unexpected Gray Fox and Red Fox make a dusk appearance.

Virtually Live 15 Polar Vortex & The Wolf: Birding Sax-Zim Bog Feb 2021

[**I apologize to all my subscribers…I sometimes forget to post to my thephotonaturalist.com blog. 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.

Virtually Live 14 —BRRRRdathon 2021 Birding & Wildlife Photography Grand Marais Minnesota (Moose! )

The BRRRRdathon—World’s Coldest Birdathon episode of Virtually Live. The BRRRRdathon is an annual fundraiser for my non-profit, Friends of Sax-Zim Bog.

This week we are birding in Grand Marais, Minnesota on Lake Superior just south of the Canadian Border. Sparky is participating in the Wintergreen non-motorized division. We go along with his fat bike birding. But he takes an early morning detour inland into the Superior National Forest where he finds an amorous bull and cow Moose! During the BRRRRdathon we see Long-tailed Ducks, White-winged Crossbills and more. Find out who won this year’s event.

Virtually Live 13 Christmas Bird Count Sax-Zim Bog: Great Gray Owl, Fisher, Short-eared Owl Dec 2020

My 35th year as compiler of the Sax-Zim Christmas Bird Count turned out to be a record-breaker despite teams having to social distance. 13 hardy participants brave -10 below zero F windchills in northern Minnesota’s Sax-Zim Bog to turn up 39 species!

We also find a species NEVER recorded on the count before (revealed in the video). And I find several owls and gets some crazy cool images of a Great Gray Owl plummeting and pouncing on suspected vole victims.

We find Boreal Chickadees, accidentally film some Black-billed Magpies at the “Bison Farm,” make a visit to Loretta’s grosbeak-rich feeders and have a yummy lunch at the Wilbert Cafe.

I also share some exciting recent sightings of a Fisher chasing Snowshoe Hare and a Short-eared Owl on Stone Lake Road.

Thanks to all CBC Participants: Bill Tefft, Lori Williams, Frank Nicoletti, Abbie Valine, Dave David Benson, Lars Benson, John Ellis, Sparky Stensaas, Sarah Beaster, Clinton Dexter-Nienhaus, Kristina Dexter-Nienhaus, Tony Anthony Hertzel, Tommy Hertzel

Virtually Live 12: November Birding in Sax-Zim Bog

A frosty cold morning in Sax-Zim Bog turns up a few goodies…including a dawn Ruffed Grouse, a flock of Pine Grosbeaks (away from a feeder!), a Black-billed Magpie on a deer carcass and cooperative Rough-legged Hawk. We hike Auggie’s Bogwalk at Fringed Gentian and find an unexpected critter! Sparky also shares what your donation on today’s Give to the Max Day campaign goes to.

60 Hummers at my one feeder?!

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.”
