Pink paints the eastern sky with the promise of sunrise in a little more that half an hour.

The birds are just starting their morning songs.

Already the loon on the nest is awake, alert and looking around.

What will today bring?

The temperature is very cold but not unheard of for this time of year.  Yesterday set a new "record low high" temperature for a town not too  far away from "Loon Lake".

Right now it is only 35 degrees here for our loons.  It is still possible that it might drop to freezing in the next couple hours although I doubt it will.  Definitely there will have been frost in some parts of the state and they were predicting a hard freeze in Western Minnesota and the Dakotas.

Ahhhh the wonders of living in the Theater of Seasons.

At 2:31 am this morning we passed the two week mark since the first egg was laid.  It is hard to believe it has already been that long.

At the two week mark in the development of the chicks inside the egg, feathers have started to develop, the mouth has begun to open and the claws on the chick's feet have begun to develop.

It is hard to even comprehend the wonders that are taking place inside that egg.

Wonders too marvelous to behold.

It is so easy to take it all for granted.

To just say 'that is the way it is'.

But when you stop to think about what is really happening, it is more than the mind can take in.  How does the egg white and egg yolk of our breakfast eggs become heart and blood vessels and eyes and feathers?

And LIFE?

Who does it?  How do They do it?  Who came up with the plan?  And Who carries it out?

I know if someone told me "Go build a loon", I wouldn't have the slightest clue of where to begin.  Where to get the parts.  How to go about it.  How to make the pieces fit.  Not only how to make them fit, how to MAKE the pieces themselves before trying to fit them!

But this miracle takes place around us all the time.  And because it is so common, we do not stop to think how much of a miracle it actually is.

But that is what is going on under the loon right now.

In order for it to happen, it must be exactly the right temperature and humidity.  A few degrees too cold and the chick will not survive.  A few degrees too hot , and the chick will not survive.  But when it is just right, lifelessness becomes LIFE.

That is the pressure that our loon parents are under today.

To maintain just those right conditions for our chicks to continue their development.

Anything that would draw them off the nest for any length of time in the cold during this critical time, could prove fatal to the chicks.

Whether it be an eagle that draws them off.  Or a person.  Or an animal. Or an intruder loon.  Or a fisherman getting too close to the nest.  Or a thousand and one other things that could draw them off the nest and away from the eggs.

We worry whenever they are off the nest.

But they feel something even more profound.  What is it?  What compels them to sit on the nest hour after hour?  Day after day. In cold.  In heat.  In rain.  In wind.  

What compels them to defend the nest?

Do they actually know that in a couple more weeks they will have little chicks?

Once again we are faced with our own inadequacies and our lack of ability to understand something so deep and so profound.

And so we can only sit back and say THANK YOU!

And enjoy the wonder of LIFE itself!

We have just had a very nice and smooth nest exchange between our loons.

The male got up from the back side of the nest and just sat and waited.

The female did not seem to be in any hurry to leave.  But finally she slowly slid off the front of the nest.  The male moved onto the nest, rolled the eggs and settle down on them, tightly tucking his wingtips  around the back of the eggs to shield them from the chilly wind.

The temperature got down to 39 degrees here this morning.  And it may be even lower tomorrow morning.  There are predictions of scattered frost around the area.  And there was some scattered snow flurries reported in extreme northern Minnesota, up along the Canadian border with possibly more tomorrow.

But for our loons, it is only wind and rain and chilly weather.

But weather that could do damage to the eggs if they are exposed for very long.

This is a very crucial time in the development of the eggs.  The chicks definitely should be developing.  But they are not far enough along to generate their own warmth and heat yet.  So it is important for the parent loons to stay on the nest.

I still have not explanation for what happened Saturday night/early Sunday morning.

Whatever it was, it seemed to be pretty intense.

I thought that the territorial battles were somewhat over and that the territorial lines had been drawn.  But apparently once again the loons saw and understood much more than we do.

It is interesting that loons will establish very defined territories.  You can almost plant surveyors stakes at the boundaries they are so well defined.

I got a call from  a neighbor on the other side of the lake last night.

He verified that the other pair of loons is still here and they have also  nested.  He said the nest is in almost the exact same spot that it was last year.  So I am assuming this is the same pair of loons that we banded and put data recorders on a couple years ago.

If they have chicks this year, hopefully we will be able to capture them later this summer and retrieve those data recorders.  That will give us a lot of information about where they have been and where they traveled.    We tried to capture them last year but were not able to because they did not have chicks last year.

Since you listened to many of the calls on Saturday night, this might be a good time to refresh everyone's memory of what the different calls of the loon are and what the calls mean.

Loons have 4 basic calls: the wail, the tremolo, the yodel and the hoot.

A very good resource for listening to these calls can be found at the the Cornell University Lab of Ornithology's website "All About Birds".  You can find it at http://www.allaboutbirds.org/guide/Common_Loon/sounds  and the recordings of the calls are there so that you can hear what each call sounds like.

Now for the meanings.

The WAIL is a call that loons use to keep in touch with each other.  It is a "I am hear, where are you" call.  I usually divide the calls into 2 'good' calls and two 'bad' calls, although there is not such thing as a bad call.  I simply mean that they 'good' calls mean the loons is not distressed, where as the 'bad' calls mean that the loon is very concerned about something.  The wait is a 'good' call.

The TREMOLO is a call that a loon makes when something is causing them concern.  It may be another loon, an eagle, a boat, a person, an animal - almost anything.  It is one of the 2 'bad' calls since it means the loon is concerned about something.  Both the male and the female loon will make the tremolo call.

The YODEL is the most extreme of the 4 calls.  It is made ONLY by the male and means he is very disturbed about something.  It is often used as a territorial call to warn other loons to stay away from his territory and to tell them that he is ready to fight if they insist on coming closer.  It is the second of the 2 'bad' calls.

The HOOT is a call that almost no one ever hears.  It is a very quiet call that adult loons make when they are close to each other or that an adult will make with a chick.  It is the second of the 2 'good' calls and is just communication at close quarters with not stress or concern involved.

There are two other calls that have not been well documented.

The first is the MEW.  Loon researcher Judith MCIntyre first described the mewing sound some 40 years ago but very little has been written or documented about it.  Much of that has been right here on the LoonCam since you have often heard the MEW from the loons on or around the nest.

The other call that I have seen nothing to document it, has been heard by me often during mating here on the LoonCam.  I am not aware that anyone has ever described it before.  And I don't have a good name for it yet but it is different enough that I would classify it as a separate and distinct call.  I have heard it only being made by the female.  After she has gotten up on the nest, it is a rapid series of 'clucking' sounds made by the female.  It seems to be an invitation to the male to mate.  And I have only heard it used in those circumstances.  Some of you may have heard it as well.

But like I say, I have not come up with a good name for it.  "Clucking" just does not seem to do it justice.  But it does seem to be a very unique and distinct call by the female, different from all other calls.

Once again we are able to observe and hear things on the LoonCam that we have never been able to observe before.

We are well into the countdown to the hatch somewhere around the last couple days of May to the first couple days of June.

You don't want to miss a minute of it. 

Let alone all the drama that happens in between!

Let everyone on your social media know that now is the time to start watching if they have not been watching before.

Late last night was one of the strangest nights I have ever seen on the nest.

Around midnight there were some yodels and other calls from way out on the lake.

The male on the nest answered with 6 repeated yodels but he never left the nest.

I have never observed a male yodeling repeatedly from the nest but never leaving.

Then things quieted down for about 25 minutes.

Then once again the male loon on the nest yodeled several more times.  Until he finally left the nest and swam off toward the calls coming from somewhere distant out on the lake.

It started to rain heavily.  And the eggs lay exposed to the rain.

But then a few minutes later, a loon got up on the edge of the nesting platform.  It did not get up on the nest or cover the eggs.  It just sat and looked around for a minute or so and then got back in the water.

Was it our loon?  Was it an intruder?  I could not get a look to see if it had bands.

I must say it had a creepy feel as if a burglar was casing the  joint.  It may have been one of "our loons".  But why did they not get up on the nest?

There were more repeated wails and tremolos from out on the lake.  Many of them.

But no sign of our loons returning to the nest or to cover the eggs.  At least the heavy rain had stopped after just a few minutes.

After 33 minutes off the eggs, one of the loons gets up on the nest, rolls the eggs and settles down.  It is very hard to tell in the dark but I think it may be the female.  This is also unusual because she normally has not take a shift over night.

Once again, when you think you have seen everything, something totally new happens.

Right now, the lake is like a sheet of glass.

Frogs are singing and the birds are waking up.

The forecast for today is for more rain and possible thunderstorms.  But hopefully there will not be any severe weather.

Last night there were 9 tornadoes in western Minnesota.  But thankfully I have not heard any reports of severe damage or injury.

After today, the weather is supposed to turn much colder.  With even the possibility of the temperature dropping close to freezing tomorrow morning and Tuesday morning.

Welcome to Minnesota - The Theater of Seasons!

Let's hope that in today's "play", it will be a quiet and calm one for our loons!

Sunrise   5:42 am CDT     Sunset   8:38 pm CDT

Birds sing their morning song.

Peaks of sunshine sneak through what is a mostly cloudy sky.

The lake is calm except for a few ripples from whispers of wind.

The geese seem to be much quieter now.  At least three families of geese have new goslings that apparently have hatched within the last few days.

And there is a loon sitting on a nest in Minnesota taking care of the 2 precious eggs that contain the promise of a new generation of loons.

Does life get much better?

Once again overnight the male has done the yeoman's service of sitting on the eggs, keeping them warm and keeping them protected from predators.  This last shift overnight was 15 hours and 8 minutes!

It would be interesting to know what goes through a loon's mind that drives them to spend so much time in an environment that is so foreign to them.  For being out of the water is very foreign to them.

They were made for the water.  That is where they spend their life.

But for these few short weeks, something changes and drives them to leave the water and to sit high and dry on a nest.  Out of the water.  In hot sun and cold and rain and wind and sometimes even frost and snow.  Something so deep within them causes them to totally change their behavior for these few weeks.

Luckily for us and future generations of loons that change in behavior results in 2 new loon chicks!

Today they are predicting rain moving in later this afternoon and lasting through most of tomorrow.

Temperatures are supposed to get up into the upper 70s today.  So the clouds and the rain will help to keep the loon on the nest cooler.

You will notice when the loon is sitting on the nest and the sun is out, that they will sit with their beak open.  They are doing exactly what it looks like - panting.  Much like a dog panting, it is the loon's way of coping with being out of the cool water and it helps to cool them off.

Before we had sound on the LoonCam, some people thought that the loon was calling when it had its beak open.  And they were wishing they could hear the loon calling all the time.  But no, the loon is not calling.  It is just trying to stay cool.

Loons for the most part are very silent when they are on the nest.  That seems to be a way of not drawing attention to the location of the nest.

But with today probably being a warm day, watch for the loon panting as it sits on the nest.  It would probably be much happier to be swimming in the cool water.  But sit it must.  The eggs demand it.

Also watch for something else today.

This is one of the many miracles about loons that just amazes me.

But it also makes me feel sorry for the loon.

You may notice very small flies that fly around the loon's head and land especially around the eyes and the 'nostrils'.

This is a species of black flies.  Not the kind of black flies that fly around us and bite humans.  This is a black fly that is the size of a gnat or even smaller.  But it is not a gnat either.

It is a black fly that to me is one of the stunning examples of the specialization of nature.  For these black flies are thought to feed almost exclusively on loon blood!

I shake my head every time I think of it.

How can a fly develop and survive if it only feeds on loon blood?!

The scientific name for that black fly is Simulium euryadminiculum. 

It was first described in 1949 in Ontario.  But has since been studied and verified by a number of different scientists through the years.  The latest being studies done by the University of Northern Michigan.

All of these studies seem to confirm that this particular black fly only targets loons.  In fact, in several tests, when given the choice between an old museum loon skin specimen and a live duck, the fly targeted the old loon skin!

It is not known what the attractant is.  But it is thought that one of the prime possibilities may be the smell given off from oil that loons produce and use to coat their feathers.

There is a small gland at the upper surface of the loon's tail that produces this oil.  If you watch a loon grooming, you can see them use their beak to rub against this gland.  And then they will spread that oil over their feathers.

You can actually feel and see this gland if you handle a loon.  It is a small bump on the surface back by the loon's tail.

Now as amazing as the specialization of this black fly is, one cannot help but feel sorry for our loons being tormented by the fly as they sit on the nest.

They do not have our luxury of bug sprays.  They cannot go inside a screened in porch to get away from this biting black fly.  They have to just sit on the nest and endure it.  

There have been cases observed where the black flies have become so bad that loons have actually abandoned their nest.

For no other reason than black flies, I am sure the loon would prefer to stay in the water.

So watch today for this black fly around the loon's head.

And if you want, brush your computer screen and see if you can help the loon by keeping the black flies away!!

52 degrees F    Cloudy     Wind 3 mph NW

Sunrise   5:43 am CDT     Sunset   8:36 pm CDT

On a cloudy and overcast morning, with a haze hanging in the air, our loons have just smoothly completed their nest exchange of the morning a few minutes ago.

Once again the male has taken the long shift and has been on the nest for 10  hours and 26 minutes over night.

He seems to consistently be the one this year that does the overnight nesting sitting duties.  And he also seems to be the one who does by far the longest time on the nest.

Even with the female sitting close by for the last half hour, he was in no hurry to leave.

This morning we will pass the 8 day mark since the laying of the second egg and have already passed the 10 day mark since the first egg was laid.

It is hard to believe that it has been that long already.

Last year I did a look at the development of chicks inside the egg.

I took what is known about the normal development of chicks inside chicken eggs which is well documented, and extrapolated to what might be happening with the longer incubation time of a loon egg.

At this stage today, the heart of the developing chick has already been beating for a number of days!

Blood vessels have grown.  The limbs, brain and eyes have begun to develop.  Even the beak has begun to form.

How can one even comprehend the wonder of that?!

From "nothing" in the egg just a few days ago.  To now a new living creature being formed.

I will never get over the wonder of that.

Our loon parents both seem to have matured so much this year, especially the female.

Where last year she was so skittish and would scare off the nest at the slightest disturbance - or no disturbance at all - this year she has been very faithful in the nest exchanges and sitting on the eggs.  She still is much more apt to show concern and go into hangover than the male, but she has done so much better this year.

I have assumed that she may be a very young female who is still getting used to this whole routine.  She was new to the nest in 2013.  And that year she did not even seem to dare to get up on the nest more than a couple times.  They did not nest that year.  Which was the first time in all the years I have been doing this that the loons did not nest on the platform.

But now she seems to be learning what is expected of her and is much more comfortable with the whole routine.

I have mentioned "hangover" a couple times this year but realize that I have not really explained what it means.  Most of you already know.  But some of you who are new to watching our loons, let me explain.

A loon normally sits on the nest with its head held fairly high.

However, when it senses danger it will lower its head.

This danger might be from an eagle, from a boat or canoe in the area or just about anything else that might concern them.

The more concerned they become, the lower their head will go.

They will not leave the nest.  Yet.  But the lower their head is, the more concerned they are about whatever it is that has caused the disturbance.

They are trying to lower their profile and their visibility.

As they continue to become more concerned, their head will go lower and lower.  Until they are laying it right down against the nest.  With their neck outstretched.  They can still watch everything that is going on around them, but they have dramatically reduced their visibility.

It is what we call "hangover" position.

If the threat goes away, they will gradually raise their head again as they become more comfortable.

But if the threat does not go away, or especially if it continues to get closer, the loon may very well leave the nest.

They will swim away from the nest hoping to draw the threat away from the nest.  And apparently also draw attention away from the location of the nest.

That is why I encourage fishermen and canoeists or anyone on or around the water where there are loons, keep your eyes open and be aware of your surroundings.

If you see a loon on a nest, keep your distance.

We all want to see a loon closeup on the nest because it is something that we never get a chance to see.

And that is the beauty of the LoonCam!

You are able to watch the loons on the nest close up and never disturb them one iota.

Everything you see is their natural behavior.

It is something that researchers from years ago could only dream about.  But now we take it for granted.

But if you see a loon in the wild that is on a nest, don't approach it even though everything in your body says you want to get a closer look.  Carry a pair of binoculars with you and then you can watch 'close up' from a distance and not disturb the loons.

Usually if you stay about 300 feet away from the nest, the loons will not care and you are not stressing them.  If the loon starts to go into hangover position, it means you are getting to close to them for the loon to be comfortable.  Slowly back away and they will once again raise their head as they become more comfortable.

Our here on the LoonCam is a perfect example of the difference in loons themselves, even the same pair.

The male of this pair very seldom goes into hangover unless he is really concerned about something.  The female, however, is still prone to go into hangover over the slightest little thing.  Or sometimes what to me looks like nothing at all.

Watch for that difference in behavior as you watch our loons.

Before it was hard if not impossible to know for sure which loon was on the nest.  Now that they are banded, we can easily tell "who's on first"!

The male has a blue striped band on his right leg and silver bands on his left leg.  The female has a green band on her right leg and two red (sometimes they look more orange) striped bands on her left leg.

Yesterday we had an "intruder loon" that our loons went out to confront and to keep him away from the nest.  They do not want any other loons in their territory.  Other loons can be a threat to the nest and the eggs and especially the young chicks after they hatch.

They did not get into a big battle but their was a lot of excited diving and even a couple penguin dances and calls.  Finally the intruder left the area and the loons got back on the nest.

But it always concerns me when they are off the nest for any amount of time, especially at this critical time in the development of the eggs.  And yesterday morning, the intruder drew them off the nest while it was raining.

Many times I find myself becoming concerned over things I know that I cannot control.  And so I have to just walk away.  But that is easy to say.  And hard to do.

You may experience those same feelings at times.

But the wonder of watching all of this miracle unfold before our eyes is far greater than the stress it puts on our poor hearts.

And seeing those unbelievably cute loon chicks in a few weeks makes all the heartburn and heart attacks worthwhile!

So once again today, enjoy this little peek into the lives of our loons.

It should clear off later today and we should see some sunshine on our beautiful loons.

And with the rain we have gotten, you can almost see the plants on the nest grow.

Enjoy it all.

Have a wonderful loon-filled day!

PS  If you want to get a possible periodic email update even after our loons have left the nest and the camera has gone off, drop a note to LoonCam at yahoo.com.  I won't promise a lot of updates, but there  will probably  be a couple between now and the new loon season next year.
