Decorah North Nest

We surveyed a new nest last week. 'Decorah North' is a very large nest in a secluded valley north of Decorah. A few statistics from our trip:
  • The nest is 56 feet off the ground 
  • It is nine feet long at its longest point
  • It is seven feet wide at its widest point
  • It has a total area of 49 square feet
  • It is about 5.5 feet high
  • The eagles began building it in 2013.
Using the method listed here (http://goo.gl/WajKSb), I calculated the nest's weight at roughly 2100 pounds (using 37 pounds per cubic foot for wood weight). Good thing it is located in a sturdy white oak tree!

Kike, a professional photographer and climber, found the following bones in the nest:
  • Adult male turkey leg and and ilium
  • Turkey polt leg. 
  • Fawn leg
  • Adult raccoon skull
  • Young raccoon skull
We are looking at adding cams to this nest and will keep everyone posted on our progress. Given the nest's size and prey remains, these must be industrious, hungry eagles!

Quick note: The nest is located on private property and can't be seen from the road. We are asking everyone to respect the landowner's privacy (and cattle) and refrain from visiting the nest in person. Thank you.

Thank you once again to the RRP team! What a huge nest that is!!

oma sawyer said...

i am thrilled and I know everyone at RRP must be, since it was one of Bob's wishes. Amy, etc, etc, etc I know you all are excited and a camera would be the top of the iceberg. Thanks for keeping us in the know!!

Annie from Oregon said...

How amazingly different than N1 or N2!! Not only the nest but the size of the prey!! This will be a fascinating counterpoint in watching this 'new' nest...Thank you so much for planning ahead on the possible cams and investigating the area. I suspect these eagles might be h.u.g.e.! Sure glad Mom and Dad have marked out their territory waaaay down the road with no interlopers. :)

Kate Simpson said...

Fascinating comparison w/"our" nest ! (I think I've changed my mind about caming a second nest: it will be very interesting.)

Loyal American said...

Thank you for keeping us updated to the progress of the north nest. We look forward to the next season!

For the love of Eagles said...

I have found numerous other nests to watch throughout the year. Two in Florida are gearing up for fall eggs already, but Decorah was the first one I watched a few years ago, and always been my favorite. Thank you all for all the hard work and dedication you give. Looking forward to another exciting year. Long live the eagles!

Sue Murawski said...

It's monstrous!!!!! So glad cam install was completed safely. God bless you all.

Nora H said...

I would have sworn I posted on this before, but guess not. This looks like a fantastic nest. THANKS YOU GUYS, I know how much work it is for you!

Jan Jones said...

First I want to thank you all for the splendid work you do so we are able to see these beautiful creatures in their natural habitat. What nest is this camera viewing?

Karen Cotter said...

Delighted to see the progress made in continuing both our eagle education and social enjoyment of same. I look forward to a new year of nest completion by the mated pair, the arrival of eggs and the whole glorious but suspenseful laying, hatching, growing, care giving, and the ever present dangers and successes in the lives of "our" eagles!

Jean D. said...

Living this week with -9° temps it was so thrilling to get your email that the eagles are into house hunting! What an outstanding job of nest building, wow!
Loved seeing the eagles doing the finishing touches!!!

SusieQ2016 said...

Thanks so much for providing another nest of beautiful eagles for us to follow. That's a big nest to fill with eaglets!

Unknown said...

Around 4pm on Feb 23rd, I saw the male bring a rabbit to the nest. He sat looking around for his mate, and soon flew off with it when she didn't arrive. When I came back to the computer, both were on the nest. The cam was zoomed out, so I couldn't see clearly what was happening. From that perspective, it appeared that the female was eating, and the male was working on the grasses in the bowl.

Diane Martin said...

I am thrilled to have another nest to watch this season so close to the N2B ! This DNN is huge ! There seems to be some confusion on where this DNN nest is located. Can someone please clarify if this nest is actually "in Decorah", or is it "North of Decorah" ??? Approximately how many miles is this nest from the N2B site ? Looking forward to watching for the eggs to get here! Thanks in advance for some clarity on this subject!

Prof. Catherwood, O.D. said...

I'm happy to find out about the new cam, and I'm watching faithfully for eggs! Could you post their egg laying history for us (year/how many/dates&times laid),like is posted for Mom & Dad at N2B? Thanks again!

Christie said...

When do they usually lay their eggs? I love having two nests to watch!! Thank you so much for all your hard work!

Bert Fuhr said...

Appears first egg may have just been laid. Around 7:14 PM 03/13/2016. Female appeared to be panting shortly before and sticking tongue out. Very exciting to watch!

Christie said...

It's the 2nd egg!!!! that was just laid last night! I just saw them on the live cam! So awesome!

Cane Walker said...

Great camera shot of second egg! Thank you- intriguing to watch and follow.

Beautiful Pair

MK said...

This nest is huge! It will be fun following these eagles over the next few years.
Just a housekeeping issue - under 2016 Nesting Record - Egg#2 is listed twice. I'm sure the second listing is just a typo and should be Egg #3 but thought I would mention it.

looks like hatch in progress!!

Kelly McCreight said...

Is there a current chat for this site?

S Korff said...

I am so dismayed to see the youngest Decorah North eaglet remain so small. Parents don't seem to feed it, it's not developing at the proper rate, and it is always scree-ing for food. It's so difficult to watch, I keep promising myself I'll check back in a week to see if the chick has survived. How long will this little eaglet last? Why hasn't anyone commented on this anywhere?

S Korff said...

Whew! Finally I was able to witness a double feeding. Dad was feeding chicks one and two, while mom focused on smallest chick number three. Why is the youngest not growing at the same rate as its siblings? The age difference is minor. I'm going to guess it is due to lack of feeding (based on the times I've watched where chciks one and two were fed and three was not). Opinions?

S Korff said...

I haven't found a chat yet, but I recently published a couple of posts. Maybe we can start up a dialog here...?

goabbe said...

Where can I find the chat for the DNN nest? I understand it's 7p-8p every night

Edouard Ciccolini said...

Le plus petit est en train de s'affaiblir dangereusement !

Edouard Ciccolini said...

No food for the little one - Nothing ..... Death is coming ....

Jo Manderfield said...

I love watching the eagles nests but I can't watch the little one get ignored and stepped on. Makes me feel too sad. What seems to be the problem with Dnn3?

treelover1959 said...

I think he hatched a week after the first which is a disadvantage. didn't get as much food. Harder to get noticed. But then again it might have something wrong we don't know it might happen more often they we know since we have very few cameras and so many birds.

treelover1959 said...

But then again this might be a young couple not quite sure how to keep track of all fed. I thought he would catch up after I first saw him last week.but it has been cold. The other two just were more up front for food...It just breaks our hearts to watch. I have a Cooper hawk nest 2 door down and one morning I noticed a fledgling still in his pin feathers hanging off the branch. It was sad but somehow he got pushed out of the nest. It was sooo very high up to high to reach. I asked "hawkwatch" if I should have called to see and they said it was most probably dead if you didn't see it move. But yes next time call and they will climb the tree and see. I felt bad about not calling but I didn't think they could survive out of the nest.

Jo Manderfield said...

TY freeloader for your response. I know I'm not the only one heartbroken though. The other nest I watch is the Chesapeake Osprey. There is sadness there as well. For some unknown reason the parents left their in a storm with very cold temps for about 12 hours. Their eggs are not viable now, but she is still sitting on them. Sad.

Jo Manderfield said...

Treelover. Sorry auto spell. :(

Blake Fisher said...

I still worry about DNN3 too. I wonder if eagles sometimes have a "runt in the bunch" like dogs. I have never seen it fed, but have seen the other 2 fed many times. I see that someone posted that they saw DNN3 being fed. If it was going to die, I would think it would have. I did see it poop which I thought was a good sign.

Jo Manderfield said...

Blake, I guess all we can do is let nature take it's course.

treelover1959 said...

I think it is a young couple the female still has a dark patch on her beak. I hope for better next year. They have to figure things out. Just like we do.
It is just hard to watch but thank fully the other two are doing fantastic and they will learn.

Jo Manderfield said...

True that treelover! Where you watching from? I'm watching from central Arkansas.

treelover1959 said...

Salt Lake City. I watch EagleCrest Wildlife Ustream. Very fun spot lots of different birds. Found out about this new nest. The chat is usually off during the day and not so crazy like the other decorah nest. I tuned in this morning and they had chat on. Like it better without chat. . EagleCrest not very many chatters. Hawks, geese, coots, grebes, baby squirrels, heron,egrets. just a bunch and is on 24 hours. But we know nature is nature and when the Heron eats the baby squirrels you hope the monitor turns away fast. LOL

treelover1959 said...

I love the view of this nest. It gives a whole picture and they can pull it back to see. The other Decorah Nest they couldn't do that but I think they can with the new nest over there. That way people won't be complaining as much. But they forget we are seeing nature as nature and they don't intervene unless necessary. I Lived in Eldorado, Ark
for a year. 1981 long time ago.

Blake Fisher said...

Eduaord ended up being correct in his prediction. Sad to see that DN3 died. It did look so sickly though. I've seen a lot of articles on the Internet about sibling rivalry and the youngest eaglet not getting enough food. DN3 always looked weak though. I hate to think about it, but I assume the eagles ate the body. I think peregrine falcons do that.

Jo Manderfield said...

TY Blake for letting me know. It was so sad watching what we all knew would happen. Poor little guy. And, life goes on.....

Jo Manderfield said...

Just got the news about DNN3. So sad but was worse watching the poor little guy struggle so.

Blake Fisher said...

I saw one of the older siblings stretch its wings the other day, and accidentally hit DNN3. Looked like it knocked him/her out. It laid there for a long time without moving. I eventually quit watching, don't know how long DNN3 laid there. I was wishing they would intervene, but maybe it would have died anyway. I guess we should be thankful for the 2 that did survive.

Cindy said...

I only see one baby, did something happen to the other one too? Maybe I'm missing it.

karen vrooman said...

Is the eaglet all right? Dad brought a fish in; the eaglet sqealed and struggled but unable to get up. Dad made no move to feed it, ate the fish himself

Blake Fisher said...

Cindy, you missed a lot of posts on the RRP Facebook page. DNN2 died, they think of food poisoning. They retrieved the body and are going to do a necropsy on the body.
