50 degrees Light Rain Wind North 5mph
The mate of the loon on the nest swims very nearby.
Can it sense something about to happen?
Several crows call and the loon on the nest sits up and becomes more attentive. And then starts looking around. Looking up at the sky.
There is a wail from the loon nearby.
And then a tremolo call. And then more tremolos. The loon on the nest looks up at the sky again.
Sure enough, there is an eagle! But fortunately for this morning, the eagle is only interested in searching the lake for a meal of fish and continues flying. Both of the loons relax.
This contest between loon and eagle is one that is rooted in the shadows of history that goes back to ages unknown. But it is deep. It is indelible. It is one the loon cannot and does not ignore.
But for now, the danger has passed and the loon settles back to concentrate on the job at hand. Eggs and chicks.
Today is the 28 day mark for the first egg that was laid.
Can it already be four weeks ago?
But on the other hand, can it be only four weeks ago?!
So much has happened in those four weeks. Snow and heat and wind and rain and drought. The loon has seen it all. And stayed with it all.
So today, the vigil continues.
The vigil to watch for those little tell tale hints that something may be happening beneath the loon. That an egg might be hatching.
I saw one a few minutes ago. That slight twitch of a wing!
But was it my imagination? Or did the loon simply need to move its wing a little bit after holding it in place for so long? How much was actually there and how much was my desire to see some sign?!
So we wait. And watch. And hope.
Another bit of loon lore for you this morning.
As you watch a loon in person on your favorite lake, or maybe if one of the loons is very close to the nest but in the water, watch to see how high or low in the water it sits. It can control how high it sits in the water!
There are times when a loon feels threatened or when they are concerned about something that they will sit with not much more than their head out of the water. Their whole body is underwater. And if you were not watching for it, you would never know there was a loon in the water - maybe even very close to you!
A loon can literally sink out of sight. Not by swimming or diving. But just by literally sinking.
There are 3 or 4 things involved in its ability to do this magical disappearing act.
Unlike most birds whose bones are hollow, loon bones are almost solid and therefore much heavier than other birds. It is part of the reason that a loon needs such a long 'runway' to take off from the water. And because the bones are almost solid, they are less buoyant than a duck or a swan.
But there are a couple other unique things about loons that help them to sink out of sight when danger approaches.
They are able to squeeze the air out from between their feathers and this gives them less buoyancy. But they also have 'air bladders' in some of the muscles of their body. And by contracting the muscles around those pockets of air, they are able to reduce their buoyancy and literally sink out of sight with hardly any other movement.
Watch for it the next time you see a loon.
But today, there are more important things to watch for!
We have CHICKS to watch for!! Is today the day?

Calm and order have been restored in loonland!
There are still over 400 of you watching over our loons!
No noise...other than the ones that are supposed to be there on a Minnesota lake at night. No boats coming too close to the nest. Nothing to disturb the loons.
The white spots that you see on either side of the picture and where the picture is out of focus are due to spider webs! They show up more at night than they do during the daytime because of the infrared lights. You can also see them move slightly with the air movements.
Once in a while you will see one of the insects get caught in the web. Someone also posted a picture of the actual spider that is spinning these webs. We can only hope that he won't spin too many or that too many insects get caught in them and block our view.
Today there were thunderstorms all around but we only got "teaser" raindrops here on the loon nest. The iris and other plants are frying. You can hear how dry the material on the nest is whenever the loon moves.
Even at 10:30 at night, the loon is still sitting with its beak open and panting even though it is only 69 degrees and no humidity.
So now we continue to watch for signs that the eggs are hatching. The twitch. The slightly lifted wing. The body being raised just a little.
Tomorrow morning at 9:24am it will be 28 days for the first egg.
Will it be tomorrow?

Well, we have been through a very noisy and even stressful day!
For those of you who missed it, there has been a lot of construction noise all day today. There may be some tomorrow but nothing compared to today. And it should not last all day. Let's keep our fingers crossed.
Then tonight in an incident that I missed completely, there apparently was a boat that approached the nest way too closely. From there it is hard to know exactly what was going on without actually having seen it. Some thought stones were being thrown at the nest and others thought it was just fishermen casting toward a structure.
I can't say which one it was because I did not see it happen. I hope that there is a video of it.
But right now, everything has returned to normal. Peaceful and calm and with a loon on the nest.
So no loon chick today. Will tomorrow be the day? We are still well within the "normal range" of hatching. I will not become concerned unless we go a number of days beyond this Friday.
But for now, it doesn't get much better than it is right now!
And the loon is there faithfully playing its part in this drama. We are merely the audience. An audience that cares deeply! But an audience nonetheless.
