Population Update

Whooping Crane Update – As of August 1, 2018 

Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month birds haven’t moved much, and our first chick has fledged! A huge thank-you to the staff of Operation Migration, the Fish and Wildlife Service, the Department of Natural Resources, the International Crane Foundation, and all of the volunteers who help us keep track of the cranes throughout the year. We appreciate your contribution to the recovery of the whooping crane eastern migratory population.

Population Estimate

The current estimated population size is 101 (47 F, 51 M, 3 U). This does not include wild-hatched chicks. As of 1 August, at least 74 Whooping Cranes are in Wisconsin, 3 in Michigan, possibly 3 in Illinois, 2 in Iowa, and 3 in Minnesota. The remaining birds’ locations have not been confirmed in the last month or two. See maps below.


As of 1 August, we have had at least ten chicks hatch in Wisconsin, six of which are still alive, and one of which has fledged. Chicks in bold are currently alive.

W1_18 and W2_18 hatched to parents 12-11 and 5-11 in Juneau Co, WI. W1-18 fledged in late July.

W3_18 and W4_18 hatched to parents 24-09 and 42-09 in Adams Co, WI. W3-18 is currently alive and with its parents and has been banded.

W6_18 is still alive and with its parents 1-04 and 16-07 in Juneau Co, WI.

W7_18 and W8_18 hatched to parents 9-03 and 3-04 in Juneau Co. W7_18 is still alive.

W9_18 hatched to parents 14-08 and 24-08 in Juneau Co, and is still alive. We believe 14_08 may be dead since we have seen 24_08 alone with the chick for most of July (see below).

W10_18 hatched to parents 4-08 and 23-10 in Juneau Co, and is still alive. 

2017 Wild-hatched chicks

W3_17 (U) is still in Adams Co, WI, with 39_16. W3_17 was captured during July to be banded with uniquely colored bands and a VHF transmitter.

W7_17 (F) is still in Wright Co, MN.

Parent-Reared 2017 Cohort

19_17 (M) and 25_17 (M) left Clark County for Barron County Wisconsin during July, and are currently in Sibley Co, MN.

28_17 (M) is still in Marquette Co, WI.

24_17 (M) is in Rock Co, WI.

72_17 (M) is still in Ingham Co, MI.

38_17 (F) is still in Dodge Co, WI, where she was released in the fall.

39_17 (F) is still in Outagamie Co, WI.

Costume-Reared 2017 Cohort

7_17 is still with 4_14 (M) in Green Lake Co.

3_17 was last seen in Stephenson Co, IL with 31_16 (M) in mid-May.

4_17 (M) and 6_17 (F) moved around a bit but are back in Brown Co, WI.

1_17 (M), 2_17 (F), and 8_17 (F) have split up and 1_17 and 2_17 are currently in Franklin Co, IA. 8_17 was last seen in Sangamon Co, IL, but her whereabouts are now unknown.


We believe 14_08 (M) has died during July. We have seen his mate 24_08 alone with their chick for most of July. 14_08 was last seen 14 June. We have not found a carcass to confirm this mortality, or to determine cause of death, however due to the behavior of his mate, and the unlikeliness of 14_08 leaving his family group, we have removed him from the population totals above.

Catching Cranes

On Tuesday, we managed to capture three previously tagged Sandhill cranes, which are part of our Sandhill crane mortality study. One of them was BP2.1 – one of a set of twins, whose original tracking device had fallen off after a couple of weeks.

Brooke and Colleen approached the roosting pond from the south, while Joe and I approached from the west and as soon as we neared the pond, the two adults flushed while the two chicks hunkered down in the grass as they are still incapable of flight.

Naturally, the first chick we found was the one that had the transmitter still attached. We took the opportunity to check the device and found it still functional and securely fastened so we released him and began looking for the colt with no tracking device. 

Finding a chick hiding in 4 foot tall grasses is not easy. They have this incredible ability to get under the vegetation and ‘combat crawl’ their way across a field. It’s easy to step on one so every step we make has to be calculated so we avoid hurting a crane.

The one we looked for turned out to be 2 feet to my left and as I approached it bolted, allowing Brooke and Joe to grab it.

Next on the target list were a set of twins whose transmitters had fallen off a couple of weeks ago. Colleen and Brooke were still able to keep track of them because they were the only set of twins in a known territory and were always seen with the adults.

The pasture is used by cattle and is not at all easy to navigate. Hummocks can be used to walk on but they vary in size and move when you step on them. The muck between them is almost knee-deep so one must concentrate on where you place your feet.

We were able to use a small island of trees as an approach blind and as soon as we came around the island, the two adults flushed, leaving the chicks to hide. Joe spotted the first one sitting in the tall grasses and grabbed him.

Within minutes it was tagged and released and it was only a couple minutes later when Colleen located the second colt about 10 feet from where we had tagged its sibling. It too, was tagged and released and we left the field as quickly as possible so the family could reunite.

All in all a great day capturing and radio-marking three crane colts!

Mother of the Year Award…

… Goes to this Common Merganser and her 76 (yes 76!) youngsters. 

Female common mergansers only lay about 12 eggs at a time, so it’s safe to say that not all of the babies are the offspring of Mama Merganser. In fact, female ducks have been known to travel with a few extra babies in tow.

Ducks often lay their eggs in the nests of other ducks—sometimes, they will even deposit eggs with different duck species. 

Photographer Brent Cizek recently captured this incredible scene on Minnesota’s Lake Bemidji.

Life in the Breakdown Lane

They say that if you really want to understand another person, walk a mile in his or her shoes. This is easier said than done. It’s just not that easy to pull the shoes off a stranger’s feet. At least not while they’re awake and walking. They get mad, hit 911 on their smart phone and start screaming, “Why Me? I didn’t vote for that guy!” And besides, it’s downright cruel. Strangers need their shoes. They won’t let you into Walmart without them.

They also say that whooping cranes are in Mother Nature’s Breakdown Lane. And so perhaps the best way to really understand what it’s like to be a Whooping Crane… or any other endangered species, is to pull your vehicle off the highway into the Breakdown Lane… and call AAA for a tow. I guarantee that after an hour or two of waiting, your “Eureka Moment” will arrive. “Now, Grasshopper… are you starting to get the picture?” I can speak of this with great authority because of what happened to Colleen, Jeff and I a little over a week ago.

It was early afternoon and we had just finished capturing and tagging a sandhill chick – the second of the day – in an area of Green Lake County so remote and unexplored that a lost, stone age tribe was recently discovered there by a National Geographic photographer who managed to take a few pictures of them before they ate him. We were heading home and feeling pretty good about ourselves. (Always a BIG mistake) when it happened. Our trusty tracking van decided it had had enough of our shenanigans. It coughed and sputtered, and carried us off the road and onto the Breakdown Lane for a “Time Out”.

“It’s those damned Russians again!” Jeff exclaimed, breaking our long silence.

“Still got your AAA card”? Colleen asked from the back seat.

“I don’t leave home without it” I answered. Santa Clause (my mother) gives me a AAA Card every year for Christmas. “You can’t make an omelet without breaking eggs” she says, always putting things in terms she thinks I will understand. And she should know. This would be the third time this year I’ve had to “make the call”.

And so I called Nancy at AAA. I call her so often these days that she thinks I’m hitting on her. “I’m married!” she hollered into the phone, exasperated. “Why don’t you just get out and PUSH”! Then she regained her composure and processed my tow request while assuring me that my life was not, in fact, over and that everything was going to turn out alright.

Before she bade me the sad farewell (“Parting is such sweet sorrow), she did inform me that the tow truck would only have room for one passenger. Colleen overheard my request for a set of roof racks and screamed, “I’m not Roof Rack Ready”. She then dialed our good friend Barry, who just happens to own the repair shop that attends to our vehicles. “Just walk up to the garage a hundred yards up the road, go inside and help yourself to a beer in the fridge just to your right,” Barry said. “I’ll be there to pick you up in twenty minutes.” Turns out Barry used to live right up the street. Small world. He had just moved closer to town in March. “Nothing to do out there,” he explained. Obviously, he had never thought of breaking down. Nor had he ever acquired a taste for National Geographic photographers.

Time slowly passed while a parade of cars stopped by with questions like, “Are you guys surveying?” and “Do you work for the FCC?” and “How many TV channels do you get with that antenna?” With the large antenna sticking out the roof of the tracking van roof, we get that a lot. Then Barry arrived, picked up Colleen and Jeff, and headed off for town. And as they did, I saw Colleen waving something at me through the back window. It was one of her fingers. Seems she didn’t appreciate my request for the Roof Racks!

Sometime later the tow truck arrived. “I know who you guys are,” the tow truck driver said as he winched the tracking van onto the flat bed. “I saw you on TV. How are those Herons doing, anyway?”

“Fine”, I replied. “Never better”.

Being towed through town where everyone knows your vehicle is like riding in a parade on the “Failure Float”. Really hard to muster up that “Royal Wave” for the fans. “Come back with your shield… or on it”, the Spartan General told his troops before the Battle of Thermopile.

Then, just before arriving at Barry’s, the driver’s phone rang. “It’s Nancy”, he said. “She wants me to stop and pick up the roof racks.”

“For Colleen and Jeff”? I asked.

“No…. For those Whooping Cranes!”

I sighed, shook my head… and pulled my AAA Card back out of my wallet.

Being Prepared

There are a lot of things to remember just before diving from the van to run and chase a crane colt.

You need your backpack or fanny pack that has the essentials, a couple of transmitters, eyelash glue, cyanoacrylate, scale, measuring tape, acetone, scissor, notebook, pen, pillowcase to put small birds in to weigh, sling to weigh big chicks, walkie-talkies, phone, safety glasses. You have to have your bug jackets on most mornings and a hat.

We rarely remember them all and we are particularly hard on walkie-talkies. We lose them in the field. We lose them in the van, or we just forget them.

We have checklists here and there and they help… A bit.

We try to be organized and think ahead, but Jeff really was ahead of the game when he came prepared with the chick packed and ready!

Who Knew?

Part of my vacation this past week involved helping my daughter move.  She had asked me to go to the local Tim Hortons to get coffee and breakfast for everyone as she didn’t have any food in her fridge other than bottles of water.  Normally I would use the drive thru for a quick coffee and on my way but with such a large order I actually went inside for a change. 

While I was waiting for my order I watched the television screen.  One particular infomercial caught my eye from Cottage Life about hummingbird nests.  Apparently they utilize a lot of spider webs in their nest building so that as their chicks grow the nest expands in size with them. 

So, there’s a tidbit or timbit (Canadians will get this pun) of information to start your day…

Empty Nest Syndrome and Nostalgia

The definition of nostalgia is:

a sentimental longing or wistful affection for the past, typically for a period or place with happy personal associations.

Last week was a nostalgic week.

Last summer Brooke and I were parents to seven Whooping Crane chicks. Numbers 1, 2, 3, 4, 6, 7 and 8-17.

Last Saturday two of our chicks, 6-17 and presumably 4-17 flew over White River Marsh. In this screen grab of #6-17’s GSM hit you can see her flight path in relation to camp. I wish I had been looking up at the right moment.

Today Doug and Mako Pellerin came to camp to visit and brought me a present! Mako took two of Doug’s photos from last summer, transferred them to fabric and made pillows of them!

The day Doug snapped these photos was a fun morning, the chicks were eating Dewberries and I was trying to hide. The weaning process was different for each chick. You see my two little clingers, numbers 8 -17 and 4-17 were not ready to have mom out of sight.

One my favorite things to do with them was teach them to explore and forage. Dewberries and snakes were a favorite find. 


Brooke, who is the most patient man on the face of the Earth with birds, had to lure them into the North Pond the 1st week or so. They were nervous in a new place.

Here at the North Pond is where most of the weaning took place. At first Brooke would hide in the willows while they slowly wandered away from him. Then he sat in a camo’d blind for hours a day watching to make sure they were safe, while the chicks learned to forage and explore alone.

Raising those seven chicks from hatch to first migration was a once in a lifetime experience. I am profoundly grateful that I got to be mama to seven Whooping Crane chicks. How lucky am I? Really really lucky!

The Greek word nostos means return. Algos means suffering. So, nostalgia is the suffering caused by unappeased yearning to return. It bites hard sometimes.

Monarch Butterflies – Another Long-Distance Migrator!

Each year in the early part of summer, these orange and black beauties begin to arrive in Wisconsin and other areas north of the 40th Parallel in search of milkweed leaves and nectaring plants. 

But did you know they make the trip from central Mexico? 

Wait, let’s back up a bit… 

Each Autumn, when days get shorter and the temperatures begin to cool off, monarch butterflies begin to leave breeding territories in the north, in search of a warm place to spend the winter. For monarchs, that overwintering ground can be found high up on just a few mountains in central Mexico. Once there, the monarchs huddle together by the millions on the branches of oyamel fir trees.

Those that survive the winter, reverse course in the spring and begin heading north. Some will make it to Texas where they find milkweed to deposit eggs on. Those eggs hatch – the caterpillars emerge and eat – a lot – before spending 10-15 days inside a chrysalis – and eventually emerging as a beautiful Monarch butterfly.

The new Monarch flies several hundred miles north, visiting nectaring plants along the way for nourishment. When the times is right, it finds a mate, and deposits fertilized eggs on Milkweed plants, before it eventually dies. The new offspring continue the journey northward. In fact it could take 4 or 5 generations to make the trip. 

Yesterday Colleen sent along the following photo, which shows two adult Monarch butterflies (and a couple other pollinators) nectaring on, and perhaps checking to see if the plant was suitable for ovipositing eggs. 

A. tuberosa (Butterfly weed) is the host plant for Monarch butterflies. Photo: C. Chase

This lovely orange-flowering plant is the lesser-known milkweed here in the north. It’s proper name is Asclepias tuberosa. Every garden needs this spectacular orange beauty. You never know – if you plant some, you may end up with some flying orange beauties during the too-brief time they spend here in the north.
