63 degrees   Quiet

 

I wanted to share with you information that I just received today from Carrol Henderson at the Minnesota DNR about the two eggs that did not hatch.

 

As you know, we had them x-rayed and the x-rays showed that one had not developed at all and the other one had a "small dark spot" just under the air sac.

 

Here is what Carrol's email from today said.

"Hi, Larry,

Well, on Sunday afternoon I mustered all my courage and gathered up the two loon eggs from the refrigerator (I promised Ethelle they wouldn’t smell!) and took them to the backyard with my egg drill and oologist’s blowpipe tool for blowing out the eggs.  The egg that you picked from the nest was totally rotten—infertile.  The second one that had the air sac and had floated into the lake had a small embryo of a loon chick which would have been the dark mass just under the air sac.  It had apparently died early in incubation. Uffda did it smell awful, and by the time I finished after about 30 minutes, I had a large entourage of flies observing  the process.  I have refrigerated the eggs and need to get back to them to flush out the inside of the eggs with water to remove more of the smell. They are still pretty rank."

So he has gone WAY beyond the call of duty to give us the maximum amount of information about what happened with the eggs!  He is a great person to work with and he is in charge of all the non-game wildlife programs in Minnesota!

Then he also said, "It looks at this point like we will be able to capture the three loons that we need for the satellite transmitter project at sites that include some that your contacts have provided. I will  keep you posted on our progress."

So thank all of you who gave us some insight and information about loons that have had chicks this year.  As I find out more, I will try to keep you informed.

Once again, I hope that all of you in the US have a wonderful and safe 4th of July.

And just a reminder if you are on lakes anywhere there are loons.  Remind the people you are with to be on the lookout for loons.

Adults can do fairly well with boat traffic and dive out of danger.  But even so there have been reports of adult loons hit and killed by boats and jet skis.  So just ask your family and friends to be aware that they are sharing the lake with loons.

But more important are chicks.

This is probably the most vulnerable time for chicks.

Their first two weeks of life are when there is the highest chick mortality.  Once they make it beyond two weeks, their life expectancy goes up dramatically.

Why is that?

There are several reasons.  For the first few days to a week of their life, chicks cannot dive.  They will try to dive but at most they go down a couple inches and then just pop up to the surface like a cork!  So if a fast boat or jet ski is headed straight at them and bearing down on them, they may try to dive but they cannot dive deep enough to get out of harm's way.  And they are so small that unless a boater is being very observant, he will probably not even know that he has hit and killed a baby loon.

Secondly, with a lot of boat traffic, there is a chance that the chicks will be separated from the adults.  Not only are they in danger of being hit, they are also then in danger of a large fish or turtle eating them or an eagle or gull snatching them.

So they enter one of the most dangerous periods of their lives.  And unfortunately the busy 4th of July weekend coincides exactly when so many loons have their new chicks out on the lake for the first time.  If they can make it through this weekend and the first two weeks of life, the chances of them surviving are very encouraging.

You can help by just reminding your family and friends to be on the lookout for loons and new baby chicks when they are out on the lake.  You could very well save a new generation of loons!  And with the threat of the Gulf oil disaster looming for our loons, every chick is especially important this year.

So have a wonderful holiday!  Enjoy your family and friends and our history.

And especially enjoy our LOONS!

72 degrees    Sunny   Calm 

What a picture perfect summer day.  Sunshine.  Blue sky.  An even bluer lake.  And no humidity!

In the words of the old commercial, "From the Land of Sky Blue Waters!"

And what a perfect day for the release of a loon!!

I got a call from the Executive Director of the Wildlife Rehabilitation Center this morning to tell me that they were ready to release the loon - "Sue's loon" which has now become "Jodi's loon".  [Jodi, I had understood that your name was on the admittance tag but did not know the connection between you and 'Sue' until I saw your message.  Btw, I bought my pontoon from your family!!]

I was so surprised to hear that the loon was well enough to be released.  In fact, they were already on the way to the lake with the loon.

Yesterday afternoon I was not encouraged by the news at all.  The news that the loon still was not able to use it leg and was just sitting on a platform in the water was not what I had hoped to hear.  And then to hear that there might be nerve damage to the leg added to my concern....even if the word was that the nerve damage "could" heal.  There were no guarantees that the nerves WOULD heal.  Or guarantees of how long it would take to heal.

So I was surprised but elated to hear this morning that the loon was already doing well enough to be released today.  I was honored to be asked to help with the release on a moment's notice.  So in between a meeting this morning and a doctor's appointment right after lunch, I quickly headed to the lake where the loon was originally found.

There I met one of the staff members from the WRCMN and we carried the container with the loon inside to the shore of the lake.

There was another loon swimming not too far from the landing where we were going to release this loon.  We both wondered if that was the mate to this loon.  I looked carefully and there were no chicks swimming with the single loon.  That alone was encouraging but there was no way to know if these two loons were mates.

I was surprised at how calm the loon was as I opened the door of the carrier and reached inside to carefully take hold of the loon.  I had expected to hear some calls and for the loon to struggle.  But it didn't.  Only some disarrangement of feathers indicated anything was wrong.  I tried to be very careful and gentle with the loon's left leg which is the one that had been injured.

I was fully expecting the loon's feet and wings to be fluttering and flapping all over the place.  And I was especially careful and concerned about that sharp bill!

But the loon was perfectly content for me to pick it up and hold it as I walked to the water.  There was no struggle.  No panic.  No distress.  Only a couple of quiet hoots.

I gently set it into the water.  Even then it did not panic in any way.  I had expected it to very quickly swim or paddle to get away from us.  But it didn't.  It swam a few feet away from us and then turned and looked at us.  Still no urgency to get away.

It was good to see that it could use its left leg... the one that had been injured.  If it had not been able to use that leg, it obviously would not be able to swim well.

It swam several leisurely circles and stayed very close to us...only a few feet away as we watched from shore.  It started to rearrange its feathers that had been all tousled up in the transfer.  

And then that iconic loon pose as it rose up out of the water and flapped its wings as if to say "Free at last!  Free at last""

It also would not have been able to rise up in the water like that if it did not have good use of both legs.  And then it slowly and quietly started to swim out into the lake.

We were hoping that it would call to see if the other loon responded.  But it did not call.  Only a couple of quiet hoots as if to say "Thank You".

But the other loon did start to swim in the general direction of the loon that we had just released.  But there were no calls.  Only the quiet of a beautiful summer day punctuated by the sound of boats and jet skis.  People who were totally unaware of the awesome event that had just taken place within their view.

We did not actually see the two loons reunite so we cannot be sure if it was the mate or not.  But there were no fights that we observed either.  Everything seemed to be peaceful and the release had gone better than we had a right to expect.  Best of all was that the loon seemed to be doing VERY well and did not seem to have any trouble swimming or diving or rising up to flap its wings.

So thanks again to the Wildlife Rehabilitation Center of Minnesota and their excellent staff for nursing this loon back to health.  And thanks to Nate and Jodi for saving this loon and starting this whole saga which had a wonderful ending!

Hopefully everyone on the lake will hear the loons calling tonight!

What a spectacular evening!

After all of the heat and humidity and storms over the last week or so, we are now into a stretch of perfect weather.  Sunshine.  No humidity.  Bright blue skies.  Light breezes.  And tonight  a spectacular sunset.

Golds and reds and crimsons and purples.  And bright rays of sun shooting up into the sky from below the horizon.  And all of it reflected in the bright blue water of the lake.  These long days of summer give the extended times of twilight that are so magical.  And so practical.  They allow you to get caught up on lawn mowing until almost 10pm!

I wanted to update you on a couple things.

A couple days ago, the loons paid a visit and came swimming by.  They came in quite close to shore and near the nest which has been pulled into the shallows by the dock.  It was like they were just taking a drive through the old neighborhood to see where they had lived and what was happening with the neighbors.  They did not stay long but just long enough to show that they still remembered and had an interest in the area.

Most of the time I do not see much of them during the times I am home.  But an occasional glimpse here and there is always nice.  They look like they are in very good health and doing well.   A couple times I have seen them with other loons on the lake.  And it is always so special when you hear them calling at night.

They don't call near as much as when they are defending territory or when they have chicks, but the occasional call is still enough to stir the soul deeply!

So rest assured that they seem to be doing well.

Some of you have asked about seeing groups of loons together and wondered if this was normal.

If they are not defending nesting territory or if they do not have chicks, it is quite normal.  Typically these would be loons that have not mated or loons who do not have chicks for whatever reason.

As you know, loons stay down on the Gulf of Mexico for the first 2 or 3 years of their lives.  But even when they come back north, they usually will not mate until they are 5 or 6 or 7 years old.  So the groups of loons that you are seeing could be some of these loons that have not yet mated.

The other thing that I wanted to update you on is the loon with the 'bad leg' that Susan and her son rescued.

I talked with the good people at the Wildlife Rehabilitation Center of Minnesota this afternoon.

The loon seems to be doing well but has a long way to go yet.

X-rays did not show any broken bones, which is good.  They feel that the reason the leg is stretched out behind is either because of soft tissue damage or possibly nerve damage.  There is no way to tell at this point what caused the injury.

I was especially concerned when I heard the words "possible nerve damage".  But they assured me that nerves can and often do heal themselves and that it is not an automatic bad diagnosis.  So all they can do is watch and wait and take care of the loon while it hopefully heals and can be released back into the wild.

However, with loons time is the enemy.

Whereas many birds can survive and even thrive in captivity, loons do not do well in captivity at all.  And few survive.  Ask yourself, when is the last time you saw a loon at a zoo.  You probably never have because there are very few zoos that even attempt it because loons are almost impossible to keep in long term captivity.  They truly are birds of the wild and part of the reason that we so identify their calls with the great wilderness areas of the north.

The folks at the Wildlife Center have graciously told me that they will try to let me know of the loons progress so that I can pass the word on to you.

If you would like more information about the Center itself, you can find them at wrcmn.org

They treat thousands upon thousands of animals each year.  They are the second largest center like this in the US, second only to a center in California.  However, the California center also treats raptors, which the Wildlife Rehabilitation Center of Minnesota does not.  But we are also fortunate enough to have the Raptor Center [http://www.cvm.umn.edu/raptor/] here in Minnesota which is also a world-renowned center.  They told me that when you combine the figures of the Wildlife Rehab Center with those of the Raptor Center, no one else in the country comes close to the number of animals treated.

So we can thank the Wildlife Rehabilitation Center for all of their good work, including the x-rays that they did on our loon eggs a couple weeks ago!

They also got another loon in yesterday from Wisconsin!

You will remember that I told you how during rainstorms loons (and other waterbirds) can sometimes mistake highways and parking lots for bodies of water and land on them.  Ducks and other waterbirds can take off when they realize their mistake.  But a loon is trapped.  He cannot take off without a long body of open water.  And so he will die unless he is rescued.

Someone was kind enough to rescue this loon also and bring him to the Rehab Center.  They said he was in good shape except for some abrasions on the bottoms of his feet.  He will also be released when it seems safe to do so.  That release will probably before "Sue's Loon" is able to be released.

So that brings you up to date on both our loons and also the loon that was rescued.

I will try to let you know of any other information as I get it.

So until we talk again, I hope all of you have a wonderful and safe 4th of July!

And watch out for loons while you are out on the lake.

69 degrees    Magic Twilight   Calm

 

Was last night amazing or what?!!

 

It was as if the loons really wanted to say 'Goodbye' to you!

 

They called over and over and over.  It is the most calling that I have heard since the night I took the egg off the nest and they called back and forth to another pair of loons before they even knew the egg was gone.

 

I could not believe how long and how often they called.

 

It was bittersweet for all of us for this adventure this year to come to an end.  Again let me tell you that I will periodically post an update for you.  They will probably be few and far between because without chicks the loons will be out and about more.  But I will try to update you once in a while.

 

Tonight I took in the swimming raft and the buoys and moved the nest closer to shore.  So now boats and fishermen do not have to worry about it.  I haven't taken the nest up to shore yet nor taken all the equipment apart.  But I will soon...I am gone for the next couple days so it will have to wait until after that.

 

It gave me a chance to have a closer look at the nest for the first time since I put it out over two months ago.  Can it really be that long ago?!

 

There are several of the willow branches near the camera and microphone wires that definitely had been gnawed.  You will remember that I was VERY concerned that the muskrat would gnaw through the cables and shut everything down.  There was no sign that he had gnawed on the wires but he definitely had gnawed on the branches!  And it was only an inch or two away from the cables....MUCH too close for comfort!

 

I also tried to see what he was so intent on eating night after night when the loon would reach out and poke him.  There was no creeping Charlie, green or dry, left in that area.  I still cannot believe that he was intent on eating creeping Charlie but it may be.  The other possibility is that I had put a cattail root over in that general area.  It seem more likely that that is what attracted him but I am not sure.

 

Also, the bowl of the nest was surprisingly shallow.  More shallow than what I have usually seen.  So it is no wonder she bumped the egg out of the nest twice.  And I have never seen that before.  I have to wonder what effect the MANIC nest-building played in that.  When she was just THROWING material up on the nest!  With the eggs already in the nest there was not the opportunity to use her feet to deepen the bowl like they would normally do.

 

Once again, behavior that I have not seen before.  I keep asking myself if this was a new and inexperienced pair of loons just learning everything for the first time.  She really had taken almost all the vegetation she could get loose from around the iris and daylilies.  They were left high and dry!  It is amazing that they even survived.  She had even gotten one small daylily bulb up INTO the nest where it was growing!

 

The side of the nest facing out to the lake was especially low and I think that contributed to the egg ending up in the lake.

 

I received report from the DNR about the eggs with pictures of the eggs and the X-ray.  I thought you might like to see them so I tried to upload them here but could not.  So I sent them to MN Bound and have asked them to post them so that you can see them.

 

Here is the latest that came with the pictures [this is similar to what I already gave you]:

"Hi, Larry. I have attached a photo of the X-rays of the two loon eggs. One appears to be infertile from the outset, with no air sac. The other one on the left has an air sac and a dark area under the air sac that could be the yolk-or an embryo that died early in development. I will find out this week when I blow the eggs. I have also included photos of the eggs for you. Best wishes, "

  

So once again it confirms that no matter how long we would have waited, the eggs would not have hatched.  So I think it was the right thing to do to remove them so that the loons could get on with their lives.

 

We had also talked about doing lead and mercury testing but a biologist said it would not show much reliable information because of the way the body handles lead and mercury.

 

So now we work on trying to identify loons that can be part of the satellite tracking project.  This has the potential for adding major knowledge about loons.  And especially about those loons that may go to the Gulf of Mexico this fall and have to deal with the after effects of the oil spill.  

 

VERY little is known about loons on their wintering grounds.  Almost no studies have been done.  So this will hopefully add even some basic information.  And then you add the challenge of the oil spill and knowing what the effect of that is, this could be some very valuable information for generations to come.

 

If any of you know of lakes that have loons with chicks from this year, there is still time to send the information to LoonCam@yahoo.com to have them considered for inclusion in this study.

 

Let me once again say how much I appreciate you!!  All of you have been just amazing.  Your knowledge that you already have about loons is impressive.  And your desire to learn even more about these wonderful birds is encouraging.  Your kind comments about the LoonCam and my blog have been humbling.  

 

So THANK YOU more than words can tell!

58 degrees  Clear  Wind ENE 2mph

Under a cloudless blue sky, several loons swim together across the lake.

There are some clouds further to the north but here our loons swim in bright sunshine on this Father's Day and the last day of spring.  The first fishermen of the day are making their way out to their favorite fishing spots.

Today loons all over the north country once again get on with living their lives.

Some now have chicks to raise.  Others are still on the nest hoping for new chicks.  And others, like our loons, will simply get on with their lives of swimming and fishing and preening.

They will bless and enrich our lives with the view of them majestically and peacefully swimming with such grace and ease.  But especially they will stir something deep within us every time we hear that call.  The call of a loon.  A call unlike any other.   A call with the ability to move us like no other bird.  To immediately conjure up memories.  To bring us back to places and times from long ago.  Whether it be time at a lake cabin or travelling by canoe through wilderness lakes or nights laying in a tent listening to the loons calling.

A call with the ability to transport us to another time and place.

Even if we have never heard or seen a loon first-hand, we are immediately captured by their beauty and grace in the water and their haunting call.  Or we are amused by their ungainly difficulty of maneuvering on land.

But no matter what it is, loons seem to have this ability to touch us in a way that very few other things can.

And so we will enjoy every glimpse of them this summer.  Until the approach of fall decides to take them from us for another year.

We can only hope for their safety as they return to the Gulf of Mexico and the Atlantic Coast.

If we are able to track some of the loons by satellite through this research project that is being planned, it will add so much more information to the base of knowledge about what is known of loons.  Not only their migration patterns but also more about their life and behavior while they are on the ocean.  So very little is known of this part of a loon's life.

Thank you for those of you who have sent me information about loons on the lakes that you have observed.  Especially if you have loons with chicks this year on the lakes where you are, would you please let me know at LoonCam@yahoo.com.  I will pass that information on to the researchers as they try to decide which loons they will monitor and which will give them the most useful information.

Many times knowledge does not come in blinding bursts.  Most of the time it comes in a little piece here and a little piece there.  But then when you stitch all those pieces together you end up with this beautiful quilt or tapestry of the life of a loon.

So hopefully, even through the LoonCam we can add another square to the quilt.

As the LoonCam 2010 season now winds down, it is with a tinge of sadness.  Not sadness about all that we have seen and learned and experienced, but sadness that it is over for the year.

Who could have predicted at the beginning of the year all that we would be a part of this year!

Eggs laid in a snow storm.  A loon sitting on the nest surrounded by heavy frost.  Blazing sun and heat.  Cloudy rainy days.  Battles with other loons.  Eggs knocked out of the nest into the water.  Possibly a change of which pair of loons is using the nest.  Two eggs that for whatever reason never had a chance of hatching.

So many twists and turns that tugged at our heart strings over and over and over.

That made us laugh.  That made us cry.  That made us sit back and just marvel at the miracle and magnificence of it all.

Nature is not predictable.  Nature writes a different story than what we expect.  And it is not at all the "perfect" story that we in our perfect world view would have written .  But it is always a story that captivates and is interesting.  And ultimately, it IS perfect.

As you have seen, the loons pay very little attention to the nest any more.  It is now just like any other spot on the lake.  And they very seldom even come up to the nest.  They have moved on and it no longer has the hold on them that it once did.  It is amazing the change that takes place in their bond to the nest.  Once again it is one more thing that we find so difficult to fully understand.

I will try to periodically post some information to let you know what I see of the loons.  But without chicks to hold them at one spot on the lake, the viewings this year will probably be much more  few and far between.  But I will try to let keep you up to date.  And I will let you know what happens with the research project.

We had looked at possibly doing lead and mercury testing with the two eggs that did not hatch this year.  But biologists tell us that with the way lead and mercury are handled within the body of a loon, testing of the eggs does not give us a good indication of the effects of these two toxic environmental metals.

We will try to save the shells of the eggs to be used for educational purposes with kids...of all ages!

Tonight we will turn off the camera for this year.  But we look forward to a new season in 2011.  So tell your friends and neighbors to watch for it along with you.

But plan on being with us in 2011 for another season of watching our favorite birds...the Common Loon!
