It has been a quiet night for the loons.

And quiet for the last day or so. Let's hope that continues.

We have had enough drama this year for two or three 'loon seasons'.

We are now officially into the Memorial Day weekend. And thousands if not millions of people have headed to the lakes all across the country. This is the first big summer holiday weekend for people here in the United States.

Wherever you are, I hope that you will take a few minutes to stop and remember those who have given the ultimate sacrifice so that we can have the freedoms that we so often take for granted. Whether you are here in the United States or anywhere around the world remember what others have sacrificed for you..

Here at the loon nest the forecast today is for more thunderstorms throughout the day. While that will help to keep down the boat traffic on the lake, the last thing that we need right now is more water. We have had enough to last us for a while.

We have passed the mid-point 'hump' for the eggs and we are now on the downward slope toward the expected hatching.

Let me go out on a limb here and make some predictions - a very dangerous thing to do! Especially this year.

The 'normal' expected hatch dates would be the evening of June 4th for the first egg and the morning of June 7th for the second egg.

However, if the eggs hatch, I would expect those dates to be earlier.

I would expect that the hatching will take place sometime between June 2nd and June 4th. There I have said it. How silly is that of me to even speculate on when it will be when everything else has been so different this year?

Let me give you a broader range of dates as well.

I would be very surprised to see any hatching before June 1st. And I would not start worrying about a potential hatch until we reach June 9th or 10th. If we get to the 9th or the 10th and there has been no hatching, then concern would start to build as to whether the eggs will hatch.

But this morning, the loon once again sits on the eggs, ever so patient.

I often ask myself if I would ever be willing to do something like that.

But the loons do it day after day.

One thing this year that is so different is that you have to give the male credit for the amount of time he has spent on the nest. He has gone above and beyond the call of duty.

Normally the male and the female loon share nesting duties almost equally. Some studies have shown that the female spends slightly more time on the nest than the male. Maybe 60% to 40%.

Bu this year on this nest, the male has spent much more time on the nest than the female.

Tomorrow the forecast is for the temperatures to reach 90 degrees and sunny for most of the day. That means that many people will come to the lake tomorrow and it will be a very, very busy day on the lake.

Boaters, fishermen, water skiiers, swimmers. Just about any activity you can imagine.

So even if the wind is calm tomorrow, you will probably see waves from the boat wakes hitting the nest.

This floating nest can normally ride up and over those waves. But natural nests can be washed away by high boat wakes. The rise in the lake level because of the heavy rain and the length of one anchor rope is still a concern. There are no easy answers of what to do, if anything, about that.

But we will watch it closely.

All of you know how very averse I am to ever approach the nest while the loons are on it.

So let us hope for the best. No more significant amounts of rain out of these thunderstorms today. And no large boat wakes tomorrow and Monday.

If you are going to be out on the lakes or if you have friends and family that will be, a very gentle reminder to be aware of boat wakes near shore or especially near loon nests would be in order.

Today, we can think about the miracle that is going on inside each of those eggs. The miracle of life itself.

Such things are too wonderful and too big to even try to understand. How a living breathing little loon chick comes from egg white and egg yolk. The very things that we so blithely eat for breakfast on so many mornings.

Yet that is what is happening right now.

And we have the privilege to be ringside spectators of this miracle of life itself.

52 degrees Clear Wind 5mph N

Sunrise 5:32am Sunset 8:47pm

A bright yellow sun shines down on our loons from a bright blue sky.

Both of those have been rare commodities the last couple days with all the rain and thunderstorms. We are now officially at the second wettest May in history for this area.

But today promises to be a spectacular "Minnesota Day"!

The nest has taken a beating over the last couple days with the high water, the wind and the waves. And the loons themselves have not helped matters by removing 'structural' vegetation that underlies the entire nest. That in turn has allowed some of the other material to wash away and you can see the framework of the floating platform itself on the front an back sides.

There is reason for concern but not 'great' concern at this point. It all depends on how much more rain we have in the next couple weeks and how much wind comes with it.

It is something that bears close watching.

Because of all the rain, the lake level has come up at least 6 inches or more over the last couple days. The neighbor's dock is now almost totally underwater and mine is close even though I raised it several inches last week. I measured last night and the water level of the lake is over 12 inches higher than when the loons first returned two months ago!

That rise in lake levels causes me great concern over what is happening to natural loon nests all across this region of the country that has gotten so much rain. I am sure many of them have flooded and have been lost.

But since the nest we are watching is on a floating platform, so far it is ok as it has risen with the rising water.

But we are probably at the limit of the length of one of the anchors ropes that is firmly attached to the bottom of the lake.

It presents a dilemna. I am averse to ever approaching the nest when the loons are actually nesting. I think that is why the loons apparently trust me - they know I am not a threat to the nest. But if there is a danger of the nest going underwater, I would go out to see if there is anything I could do. I would try to wait until a time when the loons are taking a long 'break' from the nest. But those times are few and far between because even when they are off the nest they are usually carefully watching from afar.

The nesting material on the platform has also absorbed a lot of water from the rain over the last few days. That adds a tremendous amount of weight to the nest. But so far the styrofoam and pvc pipe are doing well and holding it up out of the water.

Replacing some of the nesting material that has washed away is not as easy as it sounds.

One cannot just dump more material on the platform. It would quickly wash away as well. The 'structure' that underlies the nest would have to be rebuilt as well. And that would probably take far too long and be far to intrusive to the loons.

So we are left with only difficult choices.

The best choice is to leave everything as it is and hope that the nest survives for the next couple weeks AND that the high waters goes down somewhat. But the level of the lake will not go down overnight even though it did "come up overnight" with all the heavy rain.

Let us hope that we can do that and do not have to intervene in any way.

One of the other dangers, especially this weekend, is wakes from boats. High wakes from a boat can easily wash over a nest. Even when the boat is some distance away. The boaters have not done anything wrong (unless they purposely come close to a nest) but with the high waters, there is not much of a margin for error. So ask your boating friends to just be aware of it.

With this being Memorial Day weekend, if the weather is nice there will be thousands of people who take to the lakes for the first big weekend of the summer.

The view from the webcam is somewhat deceiving. There is still a lot of material on the nest even though some has been washed away. The nest itself still has probably at least 6 to 8 inches of material under the eggs.

Today is forecast to have light winds as is tomorrow. That is a great break for the loons. So let's hope that they have a quiet day in every way.

Some of the strange 'territorial battles' have continued. Let us hope that they have a break from them as well.

So today, let's enjoy the respite and look forward to the day that we see two new little loon chicks hatch.

Watch closely and encourage your friends to watch with you.

Because the time is so fleeting.

Unlike nests where you can watch the chicks hatch and grow for weeks or even months, when the loon chicks hatch, we only have about 24 hours to watch them. Such a short and a fleeting glimpse.

Because with loons, the chicks will usually leave the nest within about 24 hours of hatching.

And then they will be gone. They will be where they were created to be. In the water. Not bound to something as 'uncomfortable' to them as being on land.

So the next few days become more and more exciting as we wait and watch for the eggs to hatch.

62 degrees F Raining Wind Calm

Sunrise 5:33am Sunset 8:46pm

A steady rain continues on a gray morning.

Some areas of the state are reporting amounts of 4 to 6 inches of rain with more to come. The forecast is for rain to continue for most of today. They are saying that some areas may end up with an unbelievable 10 inches of rain out of this storm!

That amount of rain could raise the levels of some lakes enough that it may flood some nests of loons or other nesting waterfowl.

But for our loons, flooding the nest is not a problem - unless we run out of anchor rope on the floating platform.

Today is the two week mark for the laying of the second egg. So we are officially at the half-way mark to expected hatching.

You probably have watched the loons carefully position the eggs near the back of their body as they adjust them when they get on the nest.

Many birds have what is called a 'brood patch'.

The brood patch is an area of bare skin on the breast or stomach of a bird. This bare skin allows the bird to more efficiently tranfer their body heat to the eggs. Some birds like the eider duck are known to pull out the feathers and eider down to line their nest.

But loons do not develop a brood patch to incubate the eggs.

Instead they have an area between their legs near the back of their body that is highly enriched with blood vessels. The increased blood flow in this area allows the loon to transfer its body heat to the incubate the eggs and help them develop.

Another thing that makes loons different than most birds are their bones.

Most birds have hollow bones which cuts down on their weight. This is important in allowing the birds to become airborne easier and to fly with less effort.

However, in a loon the bones are almost solid.

This explains why a loon needs such a long 'runway' to take off from the lake - up to a quarter mile of open water.

While it makes it harder for the loon to take off and fly, it makes it easier for them to dive for fish.

Loons have been documented to consistently dive to depths of over 200 feet! And not having hollow bones helps them to do that.

Yet one more of the amazing things about our loons.

A few minutes ago, there was yet another confrontation between 'our pair' of loons.

Things had been calm for sometime with one loon on the nest and the other loon swimming just out beyond the buoys.

Then I heard 'flying tremolos' from a loon flying around the lake.

The male, who was swimming out beyond the buoys started yodeling, telling anyone who was within earshot that this territory was taken.

The loon on the nest gave a short tremolo and then left the nest and swam out to him.

A loon came flying in over the lake and landed most of the way across the very calm lake. A beautiful huge white swan is also swimming across the lake.

The two loons swam together looking towards where the third loon had landed. All was peaceful.

Suddenly there was a huge splash and both loons rose up out of the water with wings spread, facing each other.

They both dove.

One surfaced some distance away and immediately started rowing across the surface of the water all the while calling. She settled down, peered under the water and immediately started rowing and calling. The other loon surfaced nearby. Only his head out of the water. Again and again. The loon fled.

Finally everyone settled down and one of the loons returned to the nest while the other one swam further out in the lake.

The questions continue!

66 degrees Cloudy Wind 4mph S

Sunrise 5:34am Sunset 8:45pm

It has been a quiet night for the loons.

But today and tomorrow, rain returns with potentially heavy thunderstorms tonight and flash flood watches later today.

Rain is okay. But hail and wind are not needed. They already had to sit through repeated storms of small hail over the weekend. But the loon never flinched nor moved off the eggs.

Rain doesn't normally bother the loons. Unless it raises the water level in the lake too high. On this floating nest that is not an issue [unless the rise in level is so great that we run out of anchor rope length]. If the water rises, the floating nest rises along with it. That is one of many advantages of this kind of a nest.

The lake has already risen about 8 to 10 inches over the last several weeks. With the predicted heavy rain it could easily rise another couple inches tonight and tomorrow.

Rising water levels are a concern for 'natural' nests. There are many, many instances of natural nests just washed completely away when the water rises too high or too fast. So for many natural nests, heavy rain in addition to what has been a very wet month of May is a concern.

I am anxious to check out the natural nest of another nest that has been reported on this lake to see how it is faring in the higher water.

So today rain is ok.

Too much rain or hail or heavy storms are not welcome.

The last couple days has been a much quieter one in the territorial battles for the loons as well. And the perceived 'conflict' between our loons had also quieted down. Until last night.

There had been several uneventful, even normal, nest exchanges throughout the day.

About 8pm, the mate had been quietly swimming in the area for almost an hour. At 8:30pm, the loon on the nest went out to meet the mate and they swam peacefully together - for about 10 or 15 minutes.

Then there were yodels. And tremolos. And a chase.

But it was short lived and within a few minutes one of the loons returned to the nest and settled on the eggs.

But this seeming conflict among a nesting pair of loons is something that I have never seen before. Nor have I seen it described in the literature.

Does it happen in nature? Obviously yes. It is happening with this pair.

Does it happen often? That is a question that is impossible to answer since probably 99% of loons nesting takes place out of the view of humans. So we can only observe and learn from what we see. But the bigger questions may forever be unanswered.

This weekend in the northern states of America brings the first heavy human pressure on loons as Americans observe Memorial Day - the first big holiday of the summer. And people in 'lake country' head to their beloved lakes by the millions. Boaters and waterskiers and jet skis and fishermen will abound if the weather is nice.

Here at this loon nest that increased human activity will come near the end of their nesting cycle. In areas further north and in New England, it will come at the beginning of the nesting cycle for the majority of loons who nest up to a month or more later than the loons you are watching.

If you will be on the lakes or know someone who will be, encourage them to be on the lookout for nesting loons or especially loons with chicks that may have already hatched in some areas.

I usually tell people that if you stay 300 feet away from a nest, the loons will be fine and you will place very little stress on them. But if you come closer, you may actually scare them off the nest. Even that is not enough to do damage.

But what does the damage is if you scare them off the nest and then a little later someone else scares them off the nest. And then someone else. And then someone else. And then someone else. The effect is cumulative.

You will think 'we didn't bother them because they got right back up on the nest'.

But if they get scared off too many times by too many people, they may just abandon the nest. Or the more they are off the nest, the more vulnerable the eggs are to predators.

So if you are going to be on the lake, play nice and share it with the loons. Bring your binoculars with and enjoy them from a distance.

If you are a fisherman, consider replacing your lead tackle and sinkers with non-lead alternatives. One lost lead sinker picked up off the bottom of the lake by a loon is enough to kill the loon. I have not replaced all of my fishing tackle with non-lead alternatives yet either. But it is something that I am aware of and working on. Several states have campaigns called "Get The Lead Out" to protect our beloved loons and eagles who are at the top of the food chain.

So remind your fishermen friends of that. Don't nag. Just a gentle reminder is enough. And think about replacing some of your own lead fishing tackle.

That way we can help ensure that we will hear the 'call of the north woods' for generations to come. Our beloved loons.

Now is also the time to tell your family and friends and facebook friends to watch the LoonCam. We only have a couple more weeks before the chicks should hatch and that time will go so very fast. And unlike eagles, once the chicks are born the time we see them is so brief and fleeting and so special.

The chicks will leave the nest within about 24 hours of their hatching. And then they will be birds of the water that seldom if ever return to the nest.

They grace us with their presence for just a blink of the eye.
