Mammals take the spotlight in this early spring episode from Minnesota’s Sax-Zim Bog. Sparky encounters two charismatic weasel species in the Bog’s first unfrozen water of the year. 

The snow is mostly gone, but ice clings to area lakes and rivers, but Sparky finds some open water to check.

First he spots something on the ice at Sax WMA, which turns out to be a River Otter, but there is something wrong with this “mega water weasel.”

Later, while looking for early returning waterfowl at Stone Lake (Wood Duck, Canada Geese) he finds, and travels with, a fast-swimming Mink.

The day ends with a brief sunset encounter with a hunting Great Gray Owl.

Sparky shares his six favorite photos from the two days.

He also gives an update on upcoming spring and summer field trips in Sax-Zim Bog, and shares some details on Andy Forbe’s Big Green Year on behalf of Friends of 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.

This August 2020 episode explores Northern Minnesota’s Sax-Zim Bog in late summer. In this episode we go birding in the “slow” time of year. But a couple cooperative LeConte’s Sparrows in a flower-filled field steal the show. We also stop by Nichols Lake/Lake Nichols and bird the bog stretch of Admiral Road where we find Boreal Chickadees, Palm Warbler, Blackburnian Warbler, Canada jays and more.

Sparky also shows us the new platform and bench on Gray Jay Way trail north of the Welcome Center. And we go on a kayak journey on the Whiteface River where a pair of shy River Otters briefly make an appearance. Stunning emerald green and black Ebony Jewelwing damselflies perch along the riverbank.

Well, it is Valentine’s Day after all…and the pair of River Otters appears to be a cuddly couple, nuzzling, hugging, rolling around together. But now the romantics may want to quit reading and just watch the video, as the lovey dovey couple is probably a female and last year’s pup. Males and females don’t stick together very long after mating. Most groups of multiple otters we see are probably mom and offspring. Sorry.

But their behavior is quite interesting. You see quite a bit of preening and allopreening (mutual preening in social animals that helps maintain bonds). Otters must preen often to keep their fur waterproof. They dry it off by rolling in the snow or ice, then “comb” the fur with their claws, and rub oils from their underfur into the hairs. They are also rather vocal…”talking” with chortles, snuffles, snorts, huffs, and growls. You’ll also see them munching minnows…On this day I didn’t witness them eating any other food.

This video was shot last week on the St. Louis River only about 7 miles from my house. I cross the river every day on the way to preschool/work and there are often River Otters lounging on the ice near open leads.
