Ok, the retrieval of the remains of the egg went smoother than I had hoped.  Even though I had to wait for quite awhile for the loon and chick to move away and to find what felt like the right time to do it.

I was able to get it all done just before it got dark.

I was hoping to get a couple pictures before I took it off the nest but it was too dark to get a decent shot.

All of it happened without the loon being concerned or upset in the least, for which I am very grateful.  And that is why I waited.  The loon and the chick were some way out in the lake beyond the swimming raft.  The loon obviously saw me.  But he made no movement toward the nest.  He showed no sign of concern.  He made no call or noise of any kind.

I don't know if the microphone was working at the time but I tried to give you a description of what I was seeing and what I was doing.  I tried to keep my voice low, once again to keep from upsetting the loon in any way.

The egg indeed had been smashed and the yellow we saw was a combination of the yolk and the egg white.  But they were not separate or distinct at all.  They were an even pale yellow and were of a creamy consistency almost like a very creamy custard.

I imagine part of that is from the egg sitting baking in the hot sun day after day.

I expected there to be a very strong rotten egg smell.  But there was not.  The odor was slight but not entirely unpleasant.  Not that I would want to smell it a lot but it certainly was not the rotten egg smell that I expected.

There was no sign whatsoever that the egg had started to develop or that there was any blood or anything that looked like a chick.  So I have to believe that the egg was infertile and that from day one there was never any hope for a chick from this egg.

So in some ways, this might be the best ending of any difficult endings.

There never was a chick developing in the egg.  We did not lose a chick at some point.  To me the worst would have been to find that there was a chick that was almost full-term that had died in the egg.

And we did not have to make the difficult decision of when or if to remove the egg from the nest.

So we take it for what it is.  It is nature.  It happens.  And once again we have had the privilege of watching it up close, as difficult as that is sometimes.

This is the first time I have ever seen anything like this happen.

Through the years, we have had three eggs that never hatched.

But never a case like this where the loons actually broke the egg on the nest.

We will now freeze the egg remains and work with the biologists to see if there is still information that can be salvaged from the remains.

I will keep you up-to-date with any results.

Thank you all once again for your wonderful desire to learn along with us.

But it is not over yet.

We still have a beautiful little chick out there with a whole life ahead of him!

Just another quick update....
 
The loon with the chick on its back has been floating back and forth  in the area of the nest.
 
Away from the nest but too close for me to safely go out there.  Not for my safety but for the safety of the chick.
 
I am not sure if I am going to be able to remove the remains of the egg yet tonight or not.  I would still like to but we are rapidly losing daylight.  And unless the loon moves a distance away from the nest, I will not be able to do it.
 
I expect that as dark approaches, he may very well stay in the area of the nest.  And where normally I would hope that he would get up on the nest with the chick and spend the night there, tonight I do not want that.  I want to be able to collect as much of the egg as I can for analysis.
 
But like everything else with a wild nest like this, we are not in control of anything.  It is all up to the loons.
 
The other loon has disappeared somewhere out onto the lake.  I have not seen her/him for some time now.
 
If I can collect the remains tonight, I will.
  
Otherwise I will see what the morning brings and how much if anything can be retrieved.
 
So I am going back down to the lake again.  
 
To wait.  And to hope.

Well, in a strange year that did not seem like it could get any stranger, it just has!
 
The two loons and the chick just came by the nest a little after 7 pm.  I had seen them for the last couple hours since I came home quite a far distance from the nest.  It surprised me at how far away they were.
 
As the came by the nest, one of the loons with a minnow in its mouth got up on the nest.
 
As the chick swam by, the loon immediately got off the nest.  When it left, things had changed dramatically.
 
There was a big yellow splotch next to the egg!
 
When I zoomed in on the egg, it certainly looks like the egg has been crushed and the 'yellow splotch' is actually the yolk of the egg.
 
From what I can see on cam, it does not appear that there was any development inside the egg.  It must have been infertile.
 
I will stop short of saying that definitively until I can get a closer look.  But that is certainly what it looks like now.
 
Here are my plans.
 
If the loons move far enough away from the nest, I will go out to the nest and try to collect as much of the egg as I can for further analysis.  But I will not go out to the nest if I feel the loons are too close.
 
Right now one of the loons is still in the area with the chick on its back.  It is back of the camera but some distance away from the nest.  But it is still too close for me to feel comfortable in going out there.  I do not want to upset the loons or to put the chick in any danger.
 
So I will watch to see if I get a chance tonight to go collect the remains of the egg.  I would like to do it before the egg soaks into the soil or especially before the loons get back up on the nest.  But we will just have to play it by ear.
 
Over the last couple days we have been in consultation to decide what to do if the egg did not hatch.  I won't go into much more detail right now until I see what if anything we can salvage from this egg.
 
I wish I could tell you when I was going to go out there to collect the remains.  But I can't predict what the loons are going to do or where they will be.  I will just have to do it quickly when I see an opportunity.
 
The best I can tell you is to keep watching.
 
Hopefully the fan on the camera will not be running when I am out there.  I will try to explain what I am seeing and what I am doing.
 
Hopefully this can happen yet this evening.

The loon has stayed on the nest since 7:30pm last night as he and the chick kept the egg warm.

And now with the first rays of the sunrise streaking across the lake, the mate has appeared with a minnow for the chick.

The chick goes into the water, quickly followed by the adult.  And right now the two parents are catching minnow after tiny minnow to feed our growing chick.  An early morning breakfast for our favorite chick.

There are no obvious changes in the second egg.  But at least it was kept warm and protected overnight.  And the loons seem to have their priorities right in making sure that the little chick that we have is being taken care of.

But today we still wait hopefully for a miracle with that second egg.

This morning is the 28th day for this egg.

The more time that goes by and the more the egg is uncovered in the hot sun, the less the chances are that there will be a successful hatch.  But we have seen miracles before.  Maybe we will see one again with the second egg.  Hope springs eternal.

This morning it is beautiful to see a healthy, active little loon chick being brought minnow after minnow by both of his parents.  He swims from one to the other on the still surface of the lake as he takes each of the tiny minnows offered to him.  And some minnows not so tiny.

Several people have asked if I shouldn't put up some signs in the area about the loons.

That is something that we very carefully considered and decided against.

As we talked about it, we felt that any sign that was large enough to read would be so obtrusive and would never stand against a storm.  And if it was any smaller, it would simply draw people even closer to the nest as they said, "What does that sign say?  Get closer so I can read it."

So we decided to go only with buoys that make a ring around the nest itself.

The parks department was kind enough to post a sign at the public access boat landing that the MN DNR was kind enough to provide for me.  The sign says:

"Loon Nesting Area

(picture of a loon)

Help protect our State bird

-Do not approach loon nests.

-Do not approach loon families.

-Loons are a protected species.

Minnesota Department of Natural Resources"

So one hopes that common sense takes over from there.  And for the vast majority of people it does and they are very considerate and very protective of our loons.

In Minnesota,  we tend to take our loons for granted.  And we tend to take our lakes for granted thinking everyone has lakes like we do.  But such is not the case.

On the Minnesota license plates, it says "10,000 Lakes".

But that is a misnomer.  Officially there are almost 15,000 lakes that are over 10 acres in size.  In addition to that, there are countless smaller ponds and lakes.

We also forget how special loons are since we are used to seeing them and hearing them.

Minnesota has more Common Loons (gavia immer) than any state other than possibly Alaska.  We have over 12,000 loons.  The next closest number is a toss-up between Wisconsin and Maine.  Depending on the yearly estimates, Maine has about 4,000 loons and Wisconsin has about 3,500 loons.

Then the numbers drop off dramatically.

New York has 800-1,000 loons, Michigan 400-600, New Hampshire about 400 and Vermont about 200.

Then the numbers drop even further with Montana and Washington having maybe 50 loons each, although accurate estimates are hard to come by.

Most other states have no loons or only see them as they migrate in the spring and the fall.

So we tend to forget how special it is to be graced with the presence of loons and to hear their beautiful haunting call that speaks to something deep within us.  The call that is truly the call of the great wild areas of the north.

The good news is that Canada is still the home of many of our loons.  Estimates place the numbers at upwards of 200,000 loons or more that make Canada home.  This is the majority of Common Loons in the world.

The Common Loon is one of 5 different species of loons.

The one that looks the most like our Common Loon is the Yellow-billed Loon.  As the name implies, the yellow-billed loon has a yellow bill, unlike the black bill of our common loon.  And it is larger than the common loon.  Other than those two features, it is hard to distinguish from a common loon.

The other three species of loons are the Arctic Loon, the Pacific Loon and the Red-Throated Loon.  They tend to be smaller than the Common Loon and have significantly different plumage.  None of them reside in Minnesota although there have been rare sightings of them as they migrate through the area.

It is not a stretch at all to say 'we love our loons'.  And after you have seen them up close on the LoonCam, you can see why.

But we need to be reminded occasionally how truly special they are.

Let me also remind people of the special website from the United States Geological Service (USGS) that tracked the location and migration of a number of loons.  If you have not seen it before, I think you will find it very fascinating and very informative.

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

Today the forecast is for temperatures in the mid-80s and the slight possibility of rain showers or thunderstorms.  Over the weekend, the temperatures should reach into the 90s.

So we continue to watch the remaining egg and hope for a miracle.

One has to wonder what the loons themselves know and sense.

Why did the loon sit on the egg last night when it left it all alone the previous night?  We may never know the answers.  We can only know the outcome as we wait and watch and hope.  But we also have to be realistic that with each passing hour, the chances for a successful hatch decrease.

But let's continue today to hope for that 'little miracle'.

As the sun rises, one of our loons sits very close to the nest with a 'lump' under its wing.

I assume that 'lump' is our little chick, although I cannot see it.

I do not see the other loon.  Apparently neither one of them was on the second egg that remains on the nest during the night.

They have not abandoned the nest since they continue to stay nearby.  But the amount of time that the second egg has lain exposed does not give one a lot of hope for its eventual hatch.

Let's take a look at the calendar.

The commonly accepted number of days for incubation of loon eggs is 26 to 30 days.  However, with the increased amount of information that we have been able to document for a number of years, the lower end of that range seems to be more the norm.  We have seen the lower end of the range to be as low as 25.5 days.

Until the LoonCam, researchers have never been able to document the exact minute that a loon egg was laid and to know within a few hours of when a chick hatched.

The first chick this year hatched at 26.6 days.

The second egg was laid 2 1/2 days after the first egg so you would normally expect it to hatch 2 1/2 days after the first egg.  However, because of something called 'catch up', the eggs normally hatch closer to each other than the time between being laid.  

This morning is the 27th day since the second egg was laid.  So tomorrow morning would be the "normal" 28th day of incubation.  And Saturday morning would be the 30 day mark.

Those dates give us some time frames to judge by.

If we reach Saturday morning with no hatch, then things do not look good for the eventual hatching of this second egg.

So we will remain hopeful until then.

But hope will gradually diminish with each passing day.

Especially troubling is that the egg has remained uncovered for such long periods of time.

Maybe surprisingly to some, I am not as much concerned that the egg has been uncovered for a certain amount of time.  If there is a chick developing inside, by now it can generate some of its own body heat.  But the fact that one of the loons was not on it at all last night in the cool night air is of concern.

However, what is more of a concern to me that for the last two days the egg has sat out in the hot sun for most of the day.  I think that is more of a concern that the chick in the egg would overheat rather than be too cool.  Today becomes a critical day for the egg.  Will the loons sit on the egg or will it once again be exposed to the hot sun?

The good thing is that the loons are concentrating on the most important thing - that is our little chick who is so full of life.

They spent most of the day near the nest yesterday with the little chick.  A good share of the day both loons were there with the chick.  It was good to see them working together since so much of this year had seen such strange behavior between the two loons.  But for now they were concentrating on being parents and taking good care of the chick.

It is not unusual for them to stay near the nest with the chick.

What usually happens is that they will stay in the general area of the nest.  As the chick grows, they will venture further and further away.

The chick is especially vulnerable to predators and other danger for the first two weeks of its life.

The chick has great difficulty diving.  It is more like a cork.  If it tries to go underwater, it immediately just pops to the surface.  An adult can dive to get out of the way of danger, whether it be an eagle or a fast speed boat.

But the chick cannot dive to get out of the way of danger.

So if you are out on the lake, or if your friends or family are, be aware of loons swimming with little chicks and give them a wide berth.

The chick is totally dependent on the adults for its food and will be for many weeks.  The adults will dive over and over and come up with the tiniest little minnows which they bring to the hungry chick.

With the rich diet of fish, the chick grows rapidly during these first weeks.

After two weeks, the chick is able to make its first tentative dives but it will still be weeks before it is able to catch its own food.

But while we continue to watch the second egg, our chick is active and doing well.  And learning to be a little loon.

There have been several times when the loons have made the tremolo alarm call.  When I have looked to see what was bothering them, there has been no obvious danger.  No boats.  No eagles.  Nothing.

Sometimes I think that they at times are just holding 'language classes' for the chick.  And telling the chick 'OK, this is what this means and that is what that means.'

There was no better example of that than what we observed several years ago.

The loons sat near the nest with the chicks.  Over and over they called.  Wails.  Tremolos.  Hoots.  And even yodels.

There was no danger that was obvious.

And yet they went through every one of the calls.  It seemed as if they were in the classroom with the chicks and teaching them every part of 'loon language'.

Two nights ago, I heard the loons giving the tremolo alarm call over and over.

When I went to see what was bothering them, there was a boat with two fishermen well within the ring of buoys and within a few feet of shore.

I went down to the shore and said, "Can I ask you to fish off to either side?  This is a federally protected loon nesting area."

One of the fishermen said, "I don't see any signs."

I said, "What do you think all these buoys are for?"

To which he replied, "I didn't see any signs."

I shook my head as they prepared to leave and I walked back up to the house.  As I got to the house, I turned back to look.  They were continuing right through the area, still fishing.  Once again, I shook my head and one of them put out his hands as if to say, "What?!"

They didn't mean any harm to the nest or the loons.  But sometimes it is almost as if they have a sign painted on their foreheads.  I will not say what that sign says!

It was not until later that it dawned on me that they went right over the television cable that brings the picture and the sound from the nest up to the server which them broadcasts it to you to watch.

We are very fortunate that their motor did not cut the television cable.  We would have lost everything for the year.

I have yet to see anyone purposely do anything malicious to the loons or too the nest.  But sometimes being inconsiderate like this can cause inadvertant damage.

Most of the time, we love our loons 'too much'.

We want to get close to them.  We want to see the at close range.  We want to see every detail.  If we could, we would probably pick them up and cuddle them - especially those beautiful, downy, cute chicks.  But they are better enjoyed at a distance.

With the loon cam, most of the time we can enjoy them at closer range than we could ever hope to do in the wild.  We can see more and see it better than if we ever could even if we were on the lake in person.

So as we wait for that second egg, savor every glimpse that you get of our loons.

All to soon they will be gone.

Off doing what they were intended to be doing ... being loons in the wild.
