A loon sits quietly on two eggs.

It must be the male because it does not go into deep hangover when I walk out in front of the house.  The female is very shy and usually goes into hangover at the slightest little hint of anything going on.  I have never seen a loon that has been this 'shy' before.

But this loon sits confidently on the nest.  So I think it is the male.  The other loon is swimming far out into the lake from the nest - so that must be the female.

If this is the male on the nest, he may have been there since 5 pm yesterday!  I have also never seen one loon of the pair do so much of the incubation time on the nest.  That would mean he has been there for over 12 hours.  Unless there was a nest change sometime during the night, which is possible.  But with this pair, I do not think so.

I am glad that we finally have sound back due to the diligent and hard work of the good folks at Broadband (although at the moment the cam seems to be off).  The camera itself is working fine so it is once again something somewhere along the line that is not working.  One little 'piece' out of so many that does not quite 'fit'.

Thank you once again for your wonderful patience and understanding after we have had to deal with so many issues after the lightning strike.  It is amazing what something like that can do.  But then when it comes down to it, I guess it is amazing that we are able to send a picture like this at all.

So thank you for your understanding and support and concern.

Since you were able to hear the sound yesterday, let me explain some of what you are hearing.

In past years you have heard some of the squeaks and creaks and groans of the raft as it bounces in the waves.  The more waves, the more noise.  To a certain extent, it is just something we have to put up with.

The structure of the raft itself transmits those noises louder to the microphone than what you hear on the nest itself.

I have worked over the last few years to try to minimize the amount of squeaking from the styrofoam.  But as the waves move it around, there is no way to completely stop it from squeaking.

As you have seen from the reaction of the loons, it does not bother them.  It just bothers us by hearing it on the microphone.  I have stood next to the nest when it has been moving and you can barely hear any of the squeaking noise although once in a while you can hear some of it.  The structure just magnifies the sound as it transmits it to the microphone.  It is something that I keep working on to minimize it.

But there is a new sound this year that I could not figure out.

No, it is not chains.  It is not something that duct tape will help.

At first I could not figure out what it was.

I am still not 100% sure.

But I have come to the conclusion that it is the new "chick ramp" that I added last year.

Normally chicks leave the nest within about 24 hours of hatching.

But as we have seen a couple times before, especially with the chick in 2012 who loved the nest, sometimes a chick will try to get back on the nest.  It is relatively rare but they do sometimes get back on the nest.

The chick in 2012 was the most unusual one that I have ever seen.  He loved to come back to the nest over and over.  And he would come back and drag the parents with.  Finally they tired of it and just let him come back to the nest by himself.

And that may have ultimately been his undoing as we lost him later in the summer, possibly to eagles.

But normally when a chick leaves the nest, they do not return.

They are a waterbird from that time on and they stick closely to their parents.

However, especially because of the chick two years ago wanting to come back to the nest, I added a new chick ramp to help it get back up on the nest.  I had experimented with several different attempts at a chick ramp through the years.  All of which were dismal failures.

But the new chick ramp that I added last year may have solved the problem.

However, like most things in life, the solution of one problem maybe created another problem.

I think much of the sound that we are hearing this year is coming from that chick ramp and NOT from the styrofoam or other parts of the nesting platform.

Oh well.

It gives me one more thing to work on between this season and next year.

But I wanted to let you know that is probably much of the noise you are hearing when the waves hit the nest.  And since I cannot go out there while the loons are there, it is just something that we will have to put up with this year.  And maybe I can come up with a solution for next year.

The next few days promise to be warm and sunny.  A break that all of us need.

There may be some rain that comes through on Sunday and Monday, but that is to be expected this time of year.  And the loons do not mind a little more water!  At least it is not the heavy hail that some parts of the country got hit with yesterday.

Although we have even seen our loons in previous years sit on the nest through light hail storms with the hailstones bouncing off them!

What a loon will not go through just to make sure that a new generation of loons has the best chance of entering the world and surviving to continue the mystery.

A loon sits on a nest with two eggs.

All alone but ever faithful.  All through the night.  Carefully keeping the eggs warm in the chilly morning air.

It apparently is the male since it does not react to every little movement around it and go into hangover mode like this year's female seems to do so often.

The other loon is in the area but swimming in the lake well out from the nest.

One of the very interesting things that we have learned this year is how much time this male spends on the nest.  For the first time we are able to know whether it is the male or the female because the male has bands on his legs and the female does not.

I am not aware of any definitive studies on whether the male or the female does more of the incubation duties on the nest.  But I think that the conventional wisdom has been that they share nesting duties about equally, with the female spending slightly more time on the nest.

That sure is not the case with this pair.

The male was the one that did by far the majority of the nest building.

He has also been the one who has done the majority of the incubation time on the nest.

And more often than not, he seems to be the one that has the long night shift on the nest.

I don't think it is enough information to apply it to all loon pairs of whether the male or the female does the incubation.  But it is a very interesting piece of information about this particular pair of loons.

Are they the norm?  Or are they the exception?

Is it because she appears to be young and inexperienced?  Or do males do more of the incubation than had been previously believed?

As always, when you learn one thing, it simply raises a thousand more questions.

Ahhhh, but the joy of learning and always adding to what we know about these wonderful birds.

Speaking of incubation, the "normal" incubation period for loon eggs has always been said to be 28 days.  Some sources have even claimed up to thirty days or even thirty two days.

But most of what was known before the LoonCam was from observations out in the field.  While the observers were very good and very accurate, they were also handicapped by how much they could see while not disturbing the loons.  They did not know exactly when the egg was laid.  They did not know exactly when the chick hatched.

But with the LoonCam, we are able to see everything up close without disturbing the loons at all.  And we know "to the minute" when the eggs were laid.  And we know within a matter of hours of when the chicks hatch.

So the LoonCam has allowed much more accurate observations than ever before.

And the LoonCam has been changing some of the commonly accepted information about loons.

We know beyond the shadow of a doubt from a few years ago that a chick has hatched at 25 1/2 days.  And several hatches have been well below the 28 days.  So you are part of helping to learn even more about loons.

We are over one quarter of the way through this year's incubation period.  Now if we could only have a camera INSIDE the egg to watch the miracle of new life forming!  

The miracle of Creation.

I often wonder about exactly what is going on inside that egg.

And I stand back in amazement.

To think that a 'dead' egg is capable of turning into a beautiful, black, downy, little loon chick in only a matter of days.

Who did it?  Who came up with the plan?  Who carried it out?  HOW did they do it?

Some things are just too wonderful to comprehend!

So today, enjoy the wonder of Creation.  And marvel at it.

A thick brooding fog lays over the lake.

Not a wisp of air is moving.

The lake is like a mirror, reflecting the loon sitting on the nest.

She often goes into hangover - it must be the female on the nest.

Then there are voices.  Distant, disembodied voices coming from somewhere out in the fog.

Like ghosts appearing out of nowhere, a canoe with three teenagers slips into view out of the fog.

Then another.  And another.  And another.  And another.

The loon quietly slips off the nest into the water and swims away from the nest.  Not away from the canoes but out toward the canoes.  She puts herself between the nest and the canoes.

She sits watching, half submerged, with not much more than her head and neck above the water.

More canoes emerge from the fog.  Thirteen canoes in all.  

They are apparently from a YMCA camp that is located on the lake.  Out practicing their canoeing skills on a wonderfully moody foggy morning.

The male loon has now also appeared and takes up a position between the nest and the canoes along with the female.

The loons rise up in the water and flap their wings.  Not a sign of distress.  Just the normal relaxed wing flap of a loon.  They sit.  They swim.  They carefully watch the canoers.

Most of the teenagers are oblivious to the nest or the loons.  But a few of them point at the loons when they see them.

However, none of them come toward the loons or the nest.  They maintain a respectful distance.

As the last canoe passes,  the male loon starts a series of yodels in the general direction of the departing canoes.  As if to say, "Keep moving!  This is MY territory!"  He makes a total of six yodels as the canoes disappear into the fog, one by one.

And then they are gone.  Only their voices remain.

A few minutes later, the male returns to the nest and gets up on it.  His bands and his data recorder are clearly visible on his legs.

He goes through the usual routine of rolling the egg, positioning them ever so carefully and then settles down on them.  Within a couple minutes he is back up and repeats the procedure all over again.

Most birds have what is called a "brood patch" on their breast.  A bare patch of skin that they press against their eggs and transfer body heat to the eggs to incubate them.  Some birds even pull out feathers and down to create that bare patch of skin.

Loons are somewhat different, although similar in intent.

Loons tend to position the eggs far to the back of their body near the legs.

There is not a bare patch of skin there nor a brood patch.

But there is an unusually large number of blood vessels in this particular area of their body that very effectively transfers body heat to the eggs.

And that is why they so carefully roll and position the eggs far to the back of their body before them settle down on them.

Now you know why they do what they do when they are so carefully positioning the eggs.

There is one other thing that you may want to watch for.

Normally when a loon is swimming or just sitting on the nest without eggs, the tips of the wings cross and make an "X" as they lay just above the tail feathers.

However, when the loon is incubating eggs, those wing tips are carefully tucked UNDER the tail and then the tail is lowered to keep them in place.  The tail almost locks the wingtips in place.

That way the wing feathers form a very nice tight weatherproof seal against the cold or the rain.  An amazing little detail of what loons do that just adds to the wonder and magnificence of these beautiful and iconic birds.

Enjoy them today as you watch.  Look for some of those little details that add so much to our understanding of the loons.

It is hard to believe but we are already almost a quarter of the way through the incubation period of these eggs.  It will not be long before we can expect to see new loon chicks come into the world.

The mystery of all this is almost beyond comprehension and the time that we have with them is ever so fleeting.

And ever so marvelous!

What a beautiful day!

This whole week is forecast to be in the 70s all week long.  And after this long winter, Minnesotans cannot wait to get back to 'typical' weather, whatever that is.

For our loons, it is a mixed blessing.  None of the severe cold that we have had.  Although loons do not seem to mind the cold.  But there is no prediction of severe weather either.  Which is a very good thing.  Just some rain predicted for tomorrow.

But with the warmer weather, you will probably see the loons panting as they sit on the nest in the sun.  And you will probably see more black flies flying around their head and bothering them.

Some of you who were viewing tonight (and last night) saw something new.

Shortly before 10 pm tonight, you saw some bright lights illuminate the nest - or at least I assume it did.  I don't know for sure because I was down by the lake with the neighbors.

What you saw is a boat of carp fishermen.  They are bow fishing with a bow and arrows.  They have huge banks of lights on the boat that light up the water all around them.  When they see a carp, they are able to shoot at it with their bows and arrows.  The arrows have a line attached to them that they then use to reel the carp in after they have shot it.

This is something that is fairly new around here within the last few years.

I stayed down by the lake to make sure that they went around the nest and stayed outside the buoys.

But I am so glad to see from some of the comments of those of you watching at the time that the loon on the nest did not seem to be alarmed nor did he leave the nest.  That had been a big question of mine of how the loon would react. 

The lights were so bright that I could not see what the loon was doing.

The lights light up the whole shoreline almost like day.

I will be interested to actually watch it on the camera to see how the loon reacts. 

If it had been the female, I think she would have been off the nest quickly.

I am also a little concerned of what the lights may do to the camera.  The picture seems to be darker than normal when I came back up to the house.

I am sure we will see the fishermen again.  This form of carp fishing is beginning to be  more and more popular.

What little personal contact I have had with some of them, they seem to be very considerate and respectful.

It is an age old conundrum.

How do you balance everyone's rights and interests?

Loon lovers want lakes to be wild and pristine and quiet for our loons.

Fishermen want lakes just for fishing.

Water skiiers want to be able to ski anywhere, anytime.

And on and on the self interests go.

We all want what 'we' want and sometimes we forget everyone else.

That is why we put buoys around the loon nest to remind people that they should not be approaching a nest while the loons are nesting.  But other people have a right to use the lake as well.  And so we put the buoys at a reasonable distance, not too far out, without infringing on other people's rights.

One of the really good things is that in all these years of doing this, I have yet to see anyone do anything that was actually malicious or with an intent to do harm or damage.

I have seen people do some dumb things.  But not malicious things.

It is also the reason why we do not talk about the location of the camera.

Like many of us, sometimes we love our loons too much.  And so when we are out on a lake and see a loon or especially a loon nest, we want to get as close as we can and see them in closeup.

That is one of the beautiful things about the LoonCam.

We can see the loons VERY close.  And we don't disturb them in any way.  We can observe behavior on the LoonCam that we could NEVER see in the wild, even if we were the most capable biologist around.

So enjoy the LoonCam to the fullest.

And don't forget to use it as a teaching tool for your kids and grandkids.

Today has been a wonderful day in so many ways!

It started out chilly but it has been sunny and warm the rest of the day.  Last night there was a frost advisory in the area.  But we only got down to 36 degrees over night.

This morning started out with the lake absolutely calm and mirror-like as the sun came up.

But the most wonderful thing is that the LoonCam is back live and you can watch our loons.

Tell all of your friends and neighbors and kids and family and teachers and everyone that they can once again see the loons.  For those of you who are active on Facebook and twitter and other social media, now is the time to spread the word.

These days with the loons on the nest are so short and they go so fast.  The eggs will hatch in about 4 weeks from the time they were laid.  And then the little chicks will leave the nest within about 24 hours.  Never to return.  Except for our little guy in 2012 who seemed to love the nest more than anything else!

It is interesting to see the difference in behavior of the two loons.

The female is seems to be very shy and skittish.  Almost anything will send her into hangover mode.

On the other hand, nothing seems to bother the male.  He sits with his head held high almost all the time, no matter what is going on around him.

Yesterday there were 3 eagles that stayed in the area and sat in the trees on shore for a good share of the day.  They did not seem to be overtly interested in the loons and they were not targeting the loons at all.  But it was enough to send the female into hangover mode over and over.

The male simply craned his neck to keep an eye on them.

With the reaction of the female, I have been wondering if she is a relatively young and inexperienced female.  That would probably also explain why the loons did not nest last year if she was very young and inexperienced.  And it would explain why she seems to be so skittish this year.  She still is not fully comfortable with the nest or the whole process.

Let's watch to see if her behavior changes over the next few weeks as she becomes more comfortable with nesting and being out of the water.

Let's review - we have two eggs on the nest.  That is the "normal" number.  Rarely loons will lay 3 eggs and occasionally they will lay only one.  But two eggs is the normal number.

The FIRST EGG was laid at 5:17 am CDT on Monday, May 12, 2014.

The second egg was laid sometime between late Tuesday evening, May 13 and Friday afternoon, May 16.  My best guess is that the egg was laid sometime on Wednesday or maybe Thursday.  There is no way of knowing for sure since the LoonCam was down and we could not enjoy this wonderful and educational view.

Based on those dates, I would guess that the eggs could hatch as early as Friday night, June 6 or as late as Wednesday, June 11.

So now we have our goal in mind.  Now we know what we are aiming for.

But a lot can and will happen between now and then.  For those of you who have watched before, there is no predicting what will happen next.  As you have already seen this year.

I have noticed the loons already dealing some with black flies.

They are not bad yet, but as the weather warms more and more they will be an increasing problem for the loons.  We will maybe talk more about the black flies in the days ahead.

For now, enjoy the loons.  

Enjoy the nest.

Enjoy the eggs.

And look forward to two new little black downy loon chicks!
