Easter Flower of the Prairie—Pasqueflowers bloom

April 26, 2019: Glacial Ridge National Wildlife Refuge in Polk County, Minnesota.

It had been several decades since I’d seen a blooming Pasqueflower (Pulsatilla patens) [Othern synonyms: Anemone patens or Pulsatilla nuttalliana]. They are a true harbinger of spring on western prairies, and are often pushing up when snow still dots the landscape.

My main reason for driving 4 1/2 hours one-way from my homestead in Carlton County, Minnesota to the northwest corner of the state was to spend a morning with Greater Prairie-Chickens. I only had about 24 hours for the entire trip. But I wondered if I could get a bonus photo subject and find a clump of Pasqueflowers. I really didn’t think I’d find any, but while slowly cruising down a “Minimum Maintenance” dirt road, dots of color in the mainly brown landscape caught my eye. And, Yes!, it was a cluster of just blooming “Easter Flowers.”

It is the state flower of South Dakota and the Provincial flower of Manitoba. This species grows around the globe and can be found in the western U.S., Europe, Finland, Russia, Mongolia and China. Other names for this spring beauty are Prairie Crocus, Easter Flower, Windflower, Cutleaf Anemone, and Prairie Smoke in reference to its long wispy seed plumes.

The name Pasqueflower has its roots in the Christian celebration of Easter. The name for Easter in Latin and Greek is Pascha, and Hebrew Pasach,which originally referred to Passover. Many languages use this root for their current name for Easter (Påske in Norwegian, Pascua in Spanish, Pasqua in Italian, and Pâques in French). This flower gained its common name from its association with blooming at the time of Easter, likely in its range in Europe.

I’ve never seen white Pasqueflowers! Interesting that this clump was the only white ones amidst many purple clusters (see photo below).

April 26, 2019

Photographers and Birders never really get to enjoy the benefits of staying in a hotel. And this was true for me on Friday morning. I rolled in to Crookston, Minnesota late (after a 4 1/2 hour drive) and after packing my photo/video/sound gear it was already 11pm. Not much time to sleep before the alarm went off at 3:30am. No complimentary breakfast for spring/summer birders! Two granola bars would have to suffice. I had to be in the blind by 4:50am.

Even at that dark hour, the birds had beat me to the lek. Reflectors had marked the 300 yard path to the Greater Prairie-Chicken blind at Tympanuchus Wildlife Management Area in Polk County, Minnesota (in the northwestern part of the state). Honestly it was one of the nicest grouse blinds I’ve ever been in. Spacious and roomy with semi-comfy stools, and even a plywood floor! But like all blinds constructed for the public and not specifically for photographers, it lacked a low-angle shooting window. Photographers like to get eye-level shots. It makes the images more intimate and helps isolate the subject from its background. The addition of two “shooting windows” about a foot off the floor/ground would be really nice.

But as spectacular as their displays are, the sounds these guys make are simply mesmerizing. Crazy cackles, hoots, booms against a background of overhead winnowing of snipe and singing Savannah Sparrows, Grasshopper Sparrows and Western Meadowlarks. I even heard a couple Greater Yellowlegs and a Marbled Godwit. A true spring chorus!

I am far more familiar with Sharp-tailed Grouse displays, and in comparison, the Prairie-Chickens dance less and fight more. Sharptails perform fancy footwork dance displays and inflate purple throat sacs. Greater Prairie-Chickens do less dancing and seem to rely more on their impressive yellow-pink throat sacs and erected feather tufts. They also seem to face off with other males frequently.

By 9am, the energy level had dissipated and the birds melted into the brushy landscape.

**I WILL POST A VIDEO, INCLUDING SOUNDS AND SLOW MOTION, OF THE PRAIRIE CHICKEN DISPLAYS SOON. STAY TUNED!

Though there were no low angle shooting windows in the blind, I did manage to lay on my belly and shoot a couple shots under the canvas blind’s zippered door. I like the out of focus red dogwoods/willows.

Prairie-Chickens are a bird of open prairie and brushy grasslands. This part of Minnesota has thousands of acres of such habitat preserved in many Nature Conservency sites, DNR Wildlife Management Areas and the massive Glacial Ridge National Wildlife Refuge (along the old beach line of Glacial Lake Agassiz).

Brief aerial “battles” were fairly common during my 4 hours in the blind. Most often they would face-off and then one would back off and wander away. But occasionally fights would erupt.

Not much to do photographically in the pre-dawn hour…Too dark. But what is fun is to slow your shutter speed way down and crank up the ISO and try some panning motion blurs. I got about 4 good photos that I’ve included here.

Love this motion blur at a very slow 1/3 of a second. I left the blue pre-twilight background but increased the white balance in the bird to a warmer hue. I do wish it was framed on the left instead of running out of the frame, but I can live with that.

This young male (in front) was constantly trying to display in the center of the lek. But the older males (?) would immediately attack him and drive him from the center fo the lek to the fringes. They would even bite his back. I am assuming that he is just a younger individual and has not yet earned his rightful place.

36 Hours on the Prairie: Wildflowers

[August 17 & 18, 2018: I made a quick dash to the prairies of Western Minnesota in mid August. Much of my time is spent in the boreal forest and bogs of northeast Minnesota, and I was starting to get a bit claustrophobic. So off to the wide open prairies! I started at Otter Tail County’s Maplewood State Park, then on to Wilkin County (Town Hall Prairie, Western Prairie, Rothsay WMA) and continued north to the huge Felton Prairie complex in Clay County. The next day I hit Felton area again and headed north to the Glacial Ridge National Wildlife Refuge in Polk County]

Wildflowers on the tallgrass prairie peak in mid July to early August, but there were still plenty of showy plants in full bloom in mid August. It is energizing to be in an unfamiliar habitat and meeting new species, or at least species I hadn’t seen in many years. The Liatris were in full bloom on many of the dry sites. You may know Liatris as Gay Feather or Blazing-Star, but did you know that there are a bunch of different species in Minnesota? I didn’t. I even found a white variant of the normally pink-flowered forb (photos below). Monarchs and Regal Fritillaries love to nectar on Liatris.

Pink-flowered Wild Onion (Allium stellatum) was new to me, and is now one of my favorites.

I was really surprised to find Harebell (Campanula rotundifolia) growing on the dry soils of Felton Prairie (Clay County, Minnesota). I am most familiar with this delicate beauty clinging to tiny cracks in the igneous rocks on the Shore of Lake Superior! But this is a very adaptable and hardy species that can be found in many habitats.

Wild Four-o-clock (Mirabilis nyctaginea) is a native prairie species that can also be found in waste places. The “four-o-clock” in our domestic gardens was cultivated from a related European species. The name comes from the fact that this plant opens only in late afternoon. In fact the Latin “nyctaginea” means “night blooming” from the Greek.
[Glacial Ridge National Wildlife Refuge (Polk County, Minnesota)]

You can bet that I will be back out on the prairies next spring and summer to see more of our tallgrass prairie’s fantastic flowers.

Glacial Ridge NWR is in northwestern Minnesota and is a complex of prairie tracts that has been consolidated as a federal National Wildlife Refuge. It is a vast complex of “aspen parkland” prairie habitat; savannah like in that there are clusters of aspen trees dotting the grassland.

Glacial Ridge National Wildlife Refuge was established in 2004 and is Minnesota’s newest addition to the NWR system. It is a vast area, that will eventually encompass 37,000 acres (57 square miles)

It is described by the US Fish and Wildlife Service as “the largest tallgrass prairie and wetland restoration project in U.S. history.” [from wikipedia.com]

Hoar Frost Morning—Glacial Ridge National Wildlife Refuge-March 9-10

There were 20 cases of books waiting for me in Pembina, North Dakota. My printer is in Altona, Manitoba and they kindly brought a pallet of books just across the U.S. border so I wouldn’t have to pay duty. And since I was going all the way there, why not do some photography on the way?!

I left Wrenshall at 3:20 am so I could be in far western Minnesota by sunrise. And I made it! Since the radio in the van doesn’t work, podcasts keep me entertained. As I turned off US2 into Glacial Ridge National Wildlife Refuge, I knew it was going to be a spectacular morning. Thick coats of hoarfrost coated everything! Every twig, branch, blade of grass, strand of barbed wire held a coating of thick feathery frost.

Conditions were PERFECT for hoarfrost formation….Temperatures at sunrise were near ZERO degrees F and dead calm, and the day before had been above freezing so I imagine moisture from the melting snow provided the “raw material” for spectacular hoarfrost formation.

Here is some info from http://www.wikipedia.org:

“Hoar frost (also hoarfrost, radiation frost, or pruina) refers to white ice crystals deposited on the ground or loosely attached to exposed objects, such as wires or leaves.[4] They form on cold, clear nights when conditions are such that heat radiates out to the open air faster than it can be replaced from nearby sources, such as wind or warm objects. Under suitable circumstances, objects cool to below the frost point[5] of the surrounding air, well below the freezing point of water. Such freezing may be promoted by effects such as flood frost or frost pocket.[6] These occur when ground-level radiation loses cool air until it flows downhill and accumulates in pockets of very cold air in valleys and hollows. Hoar frost may freeze in such low-lying cold air even when the air temperature a few feet above ground is well above freezing.

The word hoar comes from an Old English adjective that means “showing signs of old age”. In this context, it refers to the frost that makes trees and bushes look like white hair.

Hoar frost may have different names depending on where it forms:

  • Air hoar is a deposit of hoar frost on objects above the surface, such as tree branches, plant stems, and wires.”
