A yodel comes from the male swimming near the nest.
  
From somewhere across the lake comes the answer of another male.
 
But the loon on the nest does not seem concerned.
 
I do not see any obvious reason for the yodel other than just saying, "Hey everyone.  Who ever is listening, this is MY territory!"
 
Along with everyone else, I get concerned each time the loon leaves the nest.  And this pair of loons seems to leave the nest more often than I have seen before.  The pair last year did the same thing and that is one of the reasons I think this may be the same pair as last year but possibly not the same pair as in previous years.
 
Early in the incubation period, the first egg can stand being left uncovered for relatively long periods of time before serious incubation begins.  But that doesn't mean I have to like it any more than you or that I don't get concerned about it as well.
 
I have to keep reminding myself that they loons know so much more than I do.
 
But the second guessing about what is best is still hard to keep at bay. 
 
Last night there was one loud "boom".  I thought it was fireworks and actually went outside to see what was going on.    I do not know what it was.
 
I see in looking at the chat room this morning that a number of people thought it was a gunshot and that there were several of them.  We were in the house and we only heard the one boom.
 
So I am sorry that I cannot tell you what it was.
 
I had not even thought that it might have been something related to the beavers until someone in the chatroom mentioned it.  But I cannot rule it out unless and until I find out more.  If it was related to the beavers, it would have been almost half a mile away.
 
I do know that the DNR had okayed a permit for a trapper to remove the beavers as a nuisance.  Whether he will do that with traps or with firearms, I don't know.
 
It is not unusual to hear gunfire during hunting season.  But it is unusual to hear it this time of year or at night.  I guess that is why I thought someone had set off fireworks.  Plus hunters do not hunt after dark.  But if I find out any information, I will try to let you know.
 
It was a little surprising that the loon left the nest but then as I said, this pair seems to be more apt to leave the nest for reasons known and unknown than previous ones.
 
So now the big question is will there be a second egg?
 
Loons usually lay 2 eggs.  Sometimes they will lay just one and rarely they will lay 3 eggs.
 
The second egg typically follows the first egg by 2 to 3 days.
 
Last year it was 2 1/2 days between the eggs - almost to the hour.
 
If there is going to be a second egg, I think the chances are better than even that it will be today.  And possibly this morning.
 
But as with so many other things, we are not in control.
 
We are merely observers. 
 
Today should be partly cloudy, warm, with only a 20% chance of rain.
 
So pull up a chair.  Grab a cup of coffee or hot chocolate.  Sit back.  Relax.  
 
And enjoy the show.
 
We don't know the ending.  But previous performances promise that it will keep you at the edge of your seat.

Several tremolos and a couple yodels ring out across a lake that is like a sheet of glass.
 
There is not a ripple.
 
The trees from the far shore are reflected perfectly in the calm surface.
 
If one wanted, you could stand on your head and see no difference between the views.  Other than the blood rushing to your head!
 
Whatever it is the loons see that are causing the tremolos and yodels are unseen to me.  Although I do hear the answer of a yodel from far across the lake, I cannot spot where he is.
 
But it is enough for the loon on the nest to leave.
 
It does not seem like a matter of great concern though.  Maybe just the need for a break from the nest, because both loons are swimming near the nest, seemingly unconcerned about anything now.  They are rolling on their sides, preening and looking underwater for a possible meal.
 
There are sometimes one just cannot see or explain what they see or are feeling.  Mysteries that are known only to them.
 
I was in the Twin Cities for an event last night and did not get home until late.
 
I got home just in time to hear a couple tremolos from the nest about 12:30am.  A couple tremolos that were caused by Mr Muskrat once again being up on the nest and being very inquisitive!  And the loon was not liking it at all.'
 
For those of you not familiar with muskrats, they are a water dwelling rodent that is mainly a vegetarian although some say they will feed on shellfish as well.
 
Muskrats used to be trapped for their lush fur in the early to mid 1900s.
 
In fact, I remember as a little kid that my dad and my uncle trapped hundreds of them each season.  The pelts were valuable for their fur.
 
Our muskrat has seemed to like to gnaw on the willow branches that are placed on the nest to help keep eagles from swooping down directly on the nest.
 
Although I do not like him gnawing off those willow branches, for the most part I do not think he is a danger to the loon or to the egg.
 
But he spent some amount of time gnawing loudly on something just below the camera.  That I did not like.  The gnawing was very obvious as the microphone picked up the sounds very well.  He can have the willows.  But my concern is if he would gnaw through one of the video cables or the audio cable!  We would lose picture and/or sound and there probably is not much that could be done to replace them for this season!  So for that reason alone, I would not be unhappy if he just decided to leave completely.
 
One of our faithful viewers GG captured some of the action with the muskrat last night that you can watch here.
 
After watching him for about 20 minutes, I needed to go check on something else.  So let me digress with a little story but one which very much affects our loons.  It involves beavers!
 
I mentioned a few days ago watching a beaver swim back and forth near the nest several times.
 
We have a number of beavers on this lake and they are starting to become a nuisance.  They have started damming up a creek that empties out of the lake.  We are working with the DNR as to how to control the beavers.  If they keep damming this creek, the lake level will rise to unnatural and unacceptable levels. 
 
Yesterday afternoon we had removed part of the end of the dam to see how actively they were building it.
 
So after watching the muskrat on the nest for a while and seeing that there was no immediate danger to the loon, I walked down the creek to check on the beaver.
 
While I was walking over to the creek, I heard tremolos from the lake.  And then yodels.  And more tremolos.  And answers to the tremolos and yodels.
 
In the dark and far from the camera, I could only wonder what was happening.
 
It was obvious that the male must have come up to the nest in response to the females tremolos. 
 
My mind could only conjure up images of what was happening out on the lake.  Was there a battle between the loons and the muskrat?  I was torn.  Do I continue on my expedition to check on the beavers or do I go back and check on the loons.  The tremolos and the yodels continued for sometime but finally died down.
 
When I reached the creek, sure enough.  There was a huge beaver busily repairing the end of the dam that we had removed earlier in the day.  Water was rushing through the opening and beavers seem to be drawn like a magnet to any moving water.  It seems to be in their DNA that if the water is moving, they want to dam it up.
 
With a loud slap of his tail and a huge wake, he swam back up the creek toward the lake.
 
He swam back and forth.  Wanting to come back to finish his work on the dam.  But he would only come so close with me standing there.  I am sure he was frustrated with me.  All of that rushing water getting away from him and me standing there preventing him from doing his 'beaver work' to plug the leak!
 
There were numerous big splashes further up the creek in the lake where obviously another beaver was working feverishly on something.  Although it was far enough away that I could not see around the bend in the creek to see what he was doing.  I could only hear the big KERPLUNK every so often as he slapped his tail on the surface of the water.
 
I removed a few of the new branches the beaver had place in the opening in the dam and then walked back home.  I have not been down to the dam this morning to see if they have repaired the opening or not.  But I assume they have.
 
When I did get back home, the loon was off the nest.  And according to notes in the chatroom of when she left the nest, she was off the nest for 24 minutes until she got back on at 1:27am.
 
There have been a number of questions about how long the loon can be off the nest before it endangers the eggs.  That varies depending on which stage of incubation they are in.  In the early days like we are at now, they can be off for extended periods with no apparent damage.  As long as the temperatures are not freezing.
 
Many birds and even chickens will lay large numbers of eggs over a period of days.  And those eggs can be uncovered during that time with no ill effects.  Only when they have laid all their eggs do they begin their incubation.
 
Loons are similar but obviously they usually only lay two eggs.
 
It is after the laying of the second egg that incubation begins in earnest.
 
So the egg that we have now can stand to be uncovered for some time with no apparent damage.  But we all become concerned any time the loon is off the nest.
 
We should see the second egg arrive in the next 24 to 48 hours if she follows the accepted timing that "we" set for her.  But ultimately it is up to her.
 
So if you missed the laying of the first egg, you will probably have a second chance.  Watch carefully and in the next couple days you may see the second egg being laid.

Tonight was the payoff for all of you who were so faithful in watching our loons.

WE HAVE AN EGG AT 9:54pm CDT!

After a very active evening of the loons being on and off the nest, manic nest building.

Then she just settled down as if she was already sitting on an egg.

But within a couple minutes she was up on the side of the nest and it was obvious that this was the real deal.

She spread her wings to steady herself and you could see the convulsions as she tried to move the egg along.  She was sitting in a perfect position to be able to observe the whole egg laying process.

Very quickly you could see the  egg start to appear.

With several mighty pushes, the egg popped out!

She lay on the side of the nest, wings outspread and her left leg extended back.  She was obviously exhausted from the effort.  Even though the whole thing had taken only about 5 minutes, it had been a difficult laying.

Then she did something I have never observed before.

Most of the other times I have observed a loon laying an egg, they will sit there for a few minutes and then leave the nest and get back in the water.

She did not move for over half an hour!

She lay there with her wings outspread and left leg extended back, never moving.  She simply moved her head around and was obviously alert.  But she never moved.  It was as if she had had a spinal block.

For those of you who missed it, rgeegee has posted on wonderful video on YouTube.

After about 20 minutes, it started to concern me a little bit.  Not overly concerned but since I had never seen anything like this, I began to wonder what was going on.

Finally after 34 minutes she got up, rolled the egg and sat down on it.

But then she did not move from that position for almost exactly one hour!

She finally slipped off the nest into the lake and into the darkness.  Which is where she is right now.

For those of you who may be concerned about the egg laying unguarded on the nest, it should be ok.

At this stage it can cool off without any harm.  The only danger would be frost and there is no frost forecast for tonight.

The other danger would be predators.  But eagles and seagulls would not pose a threat in the darkness.  And the muskrat that has visited the nest several times in the last few days also should not pose a threat since they are vegetarians.  If a mink or raccoon came up on the platform, either of them would be a great threat to the egg.  We have both mink and raccoons around the lake but I have never seen one of them near the nest.

The other animal that could be a threat would be a beaver.  There are a number of beavers in the area and they have been up on the nest in years past.  They would not eat the egg but simply because of their size could accidentally crush it.

But I do not worry that the egg will be in danger tonight.

So now we start the countdown to the second egg in 2 or 3 days and the hatching around June 1st!

The excitement builds.

Time to tell everyone to join you in watching the LoonCam.  And time especially to encourage your children's teachers to use it as a teaching opportunity.  Or for those of you who are teachers, to use this as a wonderful and unique opportunity to excite your students with something they will never be able to see in any other way than on the LoonCam!
