39 degrees   Clear  Wind SE 4mph

 

The weather here in Minnesota remains relatively mild for this time of year.  Today our temperature reached a high of 53 degrees F and yesterday was 60 degrees F.

It can be much colder the first part of November.  But these temperatures are not real unusual either.

But it looks like we will be in for a change over the next few days this week.

By Tuesday night, there are predictions for snow flurries across the state but I do not think there are any forecasts of any accumulation.  Just enough to remind us that we live in the north and that winter is on its way.  Between the snow and the rain predicted for Tuesday and Wednesday, hopefully we will get some much needed moisture.  It has been very dry all fall and everything needs more moisture as we go into freeze up for the winter.

I am still amazed that so many of the loons on the USGS website with satellite transmitters are still hanging on in their summer grounds.

http://www.umesc.usgs.gov/terrestrial/migratory_birds/loons/migrations.html

A few of them have begun to move but about half of them or more are still near or on their home territories.

Maybe they do not want to think of leaving their beautiful lakes for the winter either.

With some cooler weather and some snow moving in over the next few days, that may be the motivation that some of them need to start moving.  It will be interesting to see what they do this week.

This is in such sharp contrast to "our loons" who have not been around here since August.  I keep hoping that they will come back but so far I have not seen them.  That is not to say they have not been here.  Just that I have not seen them.  And of course I have been gone so much as well.

This afternoon there was a very interesting drama that played out on the lake.

For the last week or more we have had huge groups of coots on the lake.  Obviously they too are on their migration.  But it seems as if they think this lake is a very nice place to rest and relax on their journey south  There have to be at least a couple thousand coots in a couple groups.

As I was doing some yard work this afternoon trying to get things ready for winter, there was a loud sound of water.  It was like someone had turned on a waterfall right near me it was so loud.  That is the best explanation of the sound that I can think of.  A large waterfall.

I looked to see what was causing the sound and saw all the coots scampering across the surface of the water as fast as they could go.  All of them.

Then I saw the reason for their alarm.

One of the bald eagles was hovering right over where they were.

He dove!

And then he dove again.  And again.

Today he was not after fish.  It was unmistakable that he was after a coot for dinner.

But I could not see that he came up with a coot.

They high tailed it to the rushes and once in the rushes they seemed to feel they were safe from the eagle.

But the eagle kept diving.  Trying to pick off an unlucky coot that had lagged behind the larger group.

I couldn't tell if all the movement of the large group and the splashing worked as a distraction or confused the eagle.  Because a few times he dove right into the middle of the flock of coots.  But he did not catch one.  You would have thought that it would have been very easy pickings for him and that he could have closed his eyes and gotten a coot by just running into it.  But he didn't get a coot out of the large group.

So as the main body of coots split up into several smaller groups in the rushes, the eagle kept diving trying to catch a straggler.  A couple times  he actually landed in the water for a few seconds.  I fully expected that he had caught one of the birds and would soon fly away with it.

But when he made his way up out of the water, he had nothing in his talons.

After numerous attempts, the eagle tired of the chase and flew off.

The coots were fully visible to him in the rushes.  But he did not try to get them there.  Apparently the rushes were enough of a deterence to keep him from swooping down on them.

As I watched the drama, it confirmed in my mind the effectiveness of what I have been doing putting willow branches on the loon nest.  The fact that they stick up above the nest by three feet or more seems to deter the eagles from swooping directly down on the nest.

Watching the response of the coots to head directly into the rushes confirmed that they knew something I was only discovering.  And the fact that the eagle did not try to snatch them out from the rushes confirmed that it may indeed be an effective deterrent to eagles swooping down on our loons.

All this racket and commotion roused some others.  There had been a couple swans swimming further out in the lake.  They took flight loudly complaining.

Then another.  And another.

I had not initially seen the other swans out there.  But there were a total of sixteen huge beautiful white swans with black beaks and black feet that took to the air.  I had never thought about describing their call before although I have heard it many times.

It is somewhat similar to the honk of a goose but much less annoying.  Softer and more musical.  A very pleasant sound.

They rose off the lake, gained altitude and flew away, although I could still hear them.  Then they apparently made a u-turn and soon were flying over the lake and they landed again on another part of the lake.  They seemingly knew they were safe from the eagle.

A couple hours later, just as it was getting dark, I once again heard the loud 'waterfall'.  When I went to look, sure enough there was the eagle once again trying to get a coot for his evening meal.  Whether he had gotten one before I cannot say.  He did not get one while I was watching.

But the coots made a mad dash from the open water to get to the rushes as fast as they could.  They moved as a single group.  More like a swarm of bees or a large flock of starlings.  The eagle swooped again and again.  A couple times I thought he had caught one.  But when he rose up higher, there was no coot in his talons which were held low and ready for action.

After numerous attempts at catching a coot, the eagle flew up to a large tree where he could watch the flock of coots.

After maybe half an hour, the coots apparently had lost track of where the eagle was sitting and they became more confident that they were safe.

Gradually the made their way out of the reeds.  Now in three large groups.  Separate.  Instead of the one huge group that had made their way into the weeds.

I saw the eagle take off from his perch.

NOW the coots saw him and there was the loud waterfall sound again as all three groups of birds tried to get into the safety of the weeds as fast as they could.

But it was almost dark by now and the eagle must have felt that he had tried enough for one day.  For he flew off in a direction away from the lake.

It did not take the coots long to come out from the rushes in the deepening dark.  As darkness fell, they apparently felt much safer.  The last I could see of them, they were swimming in open water heading out to the middle of the lake where I assume they are right now, spending the night safe from the eagle.

So much goes on right in front of us that we never see.  Unless we take the time to stop and be quiet.  And look.  And observe.

I do not know what the proper term is for a large group of coots.  Whether it is a flock or some other name.  Like a group of larks is I think called an "exaltation of larks".

But after today and watching their reaction to the eagle, I have decided that a proper term for a large group of coots is a "waterfall of coots"!

The loons are on the move.
 
After a seemingly delayed start to the migration, many of the loons are now starting to move.
 
"Our loons" that you watched on the webcam this year departed earlier than almost any year I have seen them depart.  They departed sometime back in the latter part of August.  Both adults and chicks.  I expected to see them back on the lake again but I have not seen them here since about the third week in August.
  
What was especially surprising is that is about the earliest that they chicks could have taken their first flights.
For those of you who have been following the work of Kevin Kenow and his research at the USGS, 7 or 8 of the loons with  newly implanted satellite transmitters have begun their staging on the Great Lakes in preparation for their migration south.
 
[For those of you who may not be aware of the website, you can find it at http://www.umesc.usgs.gov/terrestrial/migratory_birds/loons/migrations.html .  
You will find it a fascinating resources to check throughout the fall as you watch the loons begin to move and then find their way down to their wintering grounds along the Atlantic Coast or along the GUlf of Mexico.  Next spring you will also be able to follow them as they make their way back north.]
 
I apologize for taking so long to update this blog but I have been on a number of trips.
 
A few weeks ago I was privileged to spend part of the day with Kevin Kenow and the great staff at the USGS facility in La Crosse, Wisconsin.  For the first time I met Bob Kratt who is the person who does the hard and tedious work of sifting through satellite data and from that producing the map that shows you exactly where the loons are and also where they have been.  It is a massive undertaking and Bob Kratt deserves a lot of thanks from all of us who are able to vicariously be a part of the loon's migration because of his efforts!
Bob has done something wonderful this year that shows all of the loons and their movements on a single page.  Check it out if you have not done so  already.  Just click the "All Migrations Summary" near the bottom of the page.
 
Yesterday I got an email from Kevin Kenow with an update on "Big John"!  Yes, the "Big John" (Loon 55480), the loon that we followed last year from St John's University campus after he had a satellite transmitter attached.
 
Big John is now on his way and currently is on Lake Michigan, just above Racine, Wisconsin.
 
Here is Kevin's email from yesterday...
 
"Big John (loon 55480) reported in from Lake Michigan yesterday, just off Wind Point (N of Racine, WI).  This is the same area that he used last fall (18-19 Oct 2010).  Big John was near Forest Lake, MN a few days ago.  As you may recall, he also stopped at Forest Lake during his 2010 migration.  We're getting more time from his transmitter than I expected!"
 
What is interesting is that he went to exactly the same area of Lake Michigan as he did last year.
 
What is amazing is that he even stopped at the same lake, Forest Lake, on his way to Lake Michigan!  It raises the question of how 'hard wired' their migration routes are or if this was just a coincidence.
 
Once again, it only serves to point out how little we truly know about these magical birds.
 
So enjoy the next few weeks as you watch the loons gather and then eventually head south on their long journeys
 
This last week I was up at the end of the Gunflint Trail in northeastern Minnesota.  For those of you in other parts of the country or especially in other parts of the world, this is one of the most wild and beautiful areas in the state if not the country.  Much of it is truly wilderness.  It is home to the world famous Boundary Waters Canoe Area Wilderness where the only means of travel in the interior is by canoe.  We were on a lake called Gunflint Lake which forms part of the border with Canada.  The shore on the other side of the lake only a mile away is Canada.  This lake was part of a super-highway 200 years ago during the days of the voyageurs.  Over this lake  flowed millions of dollars of furs that was headed to the markets of Europe, especially beaver skins to make the tophats which were all the rage in England and Europe at the time.  (I will maybe say more about this trip at sometime and also tell you about jumping in the frigid lake.  Only weeks from ice over.  TWICE!  On purpose!!)
 
One night while walking along the lake shore, I was surprised to hear a single loon call from the Canadian side of the lake near the narrows into the adjoining lake.  I had especially thought that loons along the Canadian border would have been on their way south.
 
But what a wonderful, magical moment that was to hear a loon call from the darkness of a far northern lake and to hear that call echo down the lake.  To be on the edge of the wilderness.  And yet with all the comforts of home.
 
To walk down a small road through the forest and see a Canadian lynx cross only a few feet in front of us.  A VERY rare sighting.  People who have lived there most of their lives were very jealous because they have never seen a lynx in the wild.  To have a spectacular northern lights display (although unfortunately I missed it!).
 
But all of that can wait for another time.  And another blog entry.
 
For now we can just be content in the knowledge that, even though we do not see nor hear them right now, loons are out there.  Doing well.  Being loons.  That quintessential, iconic symbol of the great northern wilderness.
 
And once in a while even calling to us.  As if just to remind us that they are there.

I received an email from Kevin Kenow this morning about the loons that were implanted with satellite transmitters last year.
Five of them are still transmitting but their batteries may not last beyond October and that is why they are not listed on the the tracking page.
But Kevin is still tracking them and has said he will update me periodically on them.  When he does, I will be sure to update you as well.  Once again the website tracking the loons this year is http://www.umesc.usgs.gov/terrestrial/migratory_birds/loons/migrations.html
 
Here is the email from Kevin:
 
"Friday, September 9, 2011  7:48AM
Hi Larry, 

I am still receiving signals from 5 of the loons radiomarked in 2010, including "Big John" [Big John is the surviving loon from St John's University].  The batteries are expected to expire in October, so we did not include these loons on this year's webpage.  However, I am keeping track of them and forwarding noteworthy movements to those interested. 

Sorry I missed your visit to La Crosse this summer. 

Best regards, 

Kevin"

Where are our loons?
 
The few times I have been able to check the last week-and-a-half with the binoculars or the telescope, I have not seen them.  I am not concerned about their safety or anything.  I am just wondering where they are.
 
Obviously they have moved on to another lake.  Or possibly even started their migration.  It is possible that I have just missed spotting them and have looked at the wrong time.  But they have probably begun moving around.
 
This is the time of year that loons start to gather in large groups called rafts in preparation for their migration south.
 
Here in Minnesota, there is a large lake in the central part of the state called Mille Lacs Lake that is a favorite staging ground for loons preparing to fly south for the winter.  Five hundred or more loons have been counted on Mille Lacs at one time in prior years.    Other large lakes serve the same purpose.
 
But one of the new pieces of information from the migration studies done last year is how important Lake Michigan is to the migration of Upper Midwest and Central Canadian loons.
 
This afternoon I got an email from Kevin Kenow of the US Geological Service officially announcing the start of tracking of loons that have had satellite transmitters surgically implanted earlier this summer [although the website actually went live a couple days ago].  There are a total of 20 loons in this new study....13 in Minnesota, 4 in Wisconsin and 3 in Michigan.  You can track the new group of loons at http://www.umesc.usgs.gov/terrestrial/migratory_birds/loons/migrations.html
 
A few of the loons have already started their movement but they are still in their general home range.  It will be interesting to see if all of these loons also go to Lake Michigan before they finally head south to the Gulf of Mexico or the Atlantic Coast.  Loons from New England and Eastern Canada will head to the upper Atlantic Coast.
 
You can read the official USGS news release at http://www.usgs.gov/newsroom/article.asp?ID=2926
 
I have asked Kevin about last year's loons but I have not heard anything from him yet.  When we did them last year, there was hope that the battery packs in the transmitters might last long enough to give us data on their migration south this fall.  Since none of the loons from last year are listed on the map, I assume that the batteries did not last long enough for this fall's migration.  If and when I hear something from Kevin, I will let you know.
 
Our beautiful northern lakes are becoming more silent.
 
Gone are the middle of the night concerts of loon tremolos and yodels and wails.  Once again we begin to realize how blessed and privileged we are to have them with us for those precious months.  And how they enrich our lives with their beauty.
There is a sense of loss and sadness about that.  Soon we will know that our loons are gone for the winter.  Realizing that we will not hear their beautiful calls all winter.  A quietness and stillness will settle over the great northern forests and lakes.  And it will not be until the ice goes out next spring that we will see them again.  And then the excitement of a new cycle starts all over again.
 
I keep hoping that we might yet see our loons and 'chicks' [they hardly qualify as chicks anymore] make at least one more stop back on the lake to say 'goodbye' before they begin their long journey.
 
But for now, we can only wonder....where are our loons?

68 degrees   Partly Cloudy  Wind Calm

 

Summer winds down.

Can it be coming to a close already?

Where did it go?

Wasn't it just yesterday that we were waiting for the ice to go out and listening for that first call that would tell us that they loons are back for the summer?

How quickly it has gone.  I am sorry that it has been sometime since I updated you but I have been out of town quite a bit again.

But I am happy to report that our loons are doing well.  Or at least they were about a week and a half ago which is the last time I actually saw them.

I got home late last night and today I looked for them on the lake but I could not spot them during the short time I was able to look.  They may have been there and I just missed them.  As you know, they can dive and disappear out of sight so quickly and stay under for long periods of time.  Or they may actually have flown to another lake which they are known to do this time of year.

The chicks should have been able to fly for the last week or two although I have not actually seen them flying.  They are now 13 weeks old.

The last time I saw them, all four loons were swimming together and seemed to be doing very well.  The chicks were still accepting fish from the parents whenever it was offered but they were also doing diving of their own and so I assume that by now they are also catching a good share of their own fish.

From a distance when you just see the silhouette of the loon, it is hard to tell the chicks from the adults.  The chicks are now almost the same size as the adults and they have the classic loon profile.  They are only slightly smaller than the adults.

Soon the fall migration south will begin once again.

And the great northern reaches will fall silent from the call of the loon.

There is a certain sadness about that and a piece that is missing in the total picture of the north woods.

But it is as it should be.

And so we are left with the hope for next spring.

The USGS has surgically implanted satellite transmitters in some more loons in addition to the ones we did last year.  So by tracking them we will begin to get a clearer picture of exactly where and when the loons migrate.  I was not able to be involved in this year's project but will give you any updates as I can when I talk to the USGS and the Minnesota DNR.

Each piece of information adds more to our understanding of loons.

For instance, it has been known for some time that the Great Lakes have been very important to migrating loons in the central part of the US and Canada.  But what was a very interesting piece of information from last fall's and this spring's migrations is how important Lake Michigan is.

Every one of the loons that had satellite transmitters flew directly to Lake Michigan.  Some of them spent several weeks there before continuing on their journey south to the Gulf of Mexico and the Atlantic Coast.  That was a new piece of information that every one of the "satellite loons" made their way to Lake Michigan before continuing south.

Now we are faced with the summer rapidly winding down.

This Labor Day weekend is the last great 'hurrah' for the summer.

Within the next month or so, the adults will begin their migration south.  It will be interesting to watch if 'last year's" implanted loons will follow the same route again this year.  And what will the loons with the new satellite transmitters do this fall?  The USGS should start updating the migration map very soon so that you can track the loons as they migrate.

Then about a month later, the 'chicks' will make their way south, never having been there before.  I always stand amazed at the miracle of that every time I think about it.

May you be blessed and may you spend time with family and friends this weekend.

Enjoy them.  

Hold them close.

Savor every moment with them.

And tell them that you love them.
