"Oak was literally blowed up, remains could be found as far as 50 m away. Two large pieces had flown till the cable line, fortunately, cable was not broked."

good morning!
thank you Liz for borrowing the pictures taken by Janis! :thumbs:

amazing to see how the oak has blown into pieces. :slap:
it was such a big tree that it's almost difficult to believe it is gone...
it is really a shame that the transmission from the camera stopped before the lightning struck. it would have been great to be able to make a slow-motion close-up clip of the blow. :mrgreen:
and a frame-by-frame gif. :whistling:

Durberts was of course jealous seeing people climbing to his nest. lucky Janis that Durberts didn't attack him, only 'called'... :laugh:

We discussed this issue with brachux yesterday - most probably the transmission has stopped at moment when the blow occured and the actual moment of strike was not transmitted. Camera has stored the stream as well and all went good when it suddenly and abruptly was stopped.. There are two components - camera and router that have burned down at the moment.

i made a Pontu clip of the last minute of the transmission and there is nothing to see. the stream just stops.


but earlier at 8:59 a lightning stroke was recorded on the camera. i happened to spot it when i was making the above clip. i could take pictures frame by frame of this one. the lightning could be seen in two frames and the after-glow in one more picture. when the flash appears one can hear an electronic 'crick' on the video: that's when an over-voltage spike was induced in the camera system. the rumble begin 10 s later so the lightning struck at a distance of little over 3 km. this lightning seemed to strike from one cloud to another, not between cloud and ground.
in this gif each picture is shown for 0.5 s but the three pictures with the lightning are shown for 1 s each, so it is a kind of slowmotion 'video'.

Hello to all :wave:
After seeing the photos kindly given by Janis is Brachux and I'm wondering if in addition to seeing Durberts you have news of the parents :unsure:
Hello Durbe, wherever you are I hope you are flying happy ... we miss you.

thank you so much for these pictures... it's wonderful to see Durberts :D but I also wonder about the parents :shock: - what a lightening strike! it's incredible how that oak has been destroyed... it would be great to know that both Robert and Durbe are also okay (obviously impossible to know just now). I really hope it is possible to set up the BS camera... But the 'end of season' is like this - with Sulev, Linda and Illmar we lost connection, so were not able to see them any more - it's one of the frustrations, I suppose :nod: :headroll:

I have observed the camera until the thunderstorm came. There were no parents to see or hear. Just like Durberts.
I am sure that all is well! :2thumbsup:

Ame, thank you for the videos. I see them at my home.
Can you make a Gif. Nest view before and after thunderstorm?

i tried to make sense of the before and after pictures but it didn't turn out well. Janis has taken his picture from a slightly different angle and not from the exact position of the camera. also the weather is quite different and the quality of Janis' picture is so much better than the camera picture in the stormy morning that the comparison doesn't work. i think it's best to wait for the new camera.

but i took the last picture from the Pontu video. the pointer cone points lower than it used to but the parent's branch is empty.
Image

i also checked the Pontu pictures and i can't say i see anyone there all morning. there are some vague spots but i can't see any eagles here. it has been difficult to see Durberts in the oak, but the parents have been relatively easy to see. i watched the Pontu video in fast-forward before the end but i couldn't see anyone in the tree.
(besides if there had been one of them i don't think it would not be possible to find any traces of them near the oak. it the oak was turned into sticks then what would happen to a bird? :shock: )
we'll have to wait. sooner or later we'll see them.

people are seldom struck and killed by lightnings although it sometimes happens. i suppose that the probability for eagles isn't much higher than for people even though they like to sit in big trees to stay in shelter from rain. i guess, however, that the eagles were all sitting in some thick bushy spruces. the oak was not as good for keeping rain.

Just wonderful to see a picture of Durberts - what devastation to the oak. AME that slow mo of the lightning strike was
very clever. Now to wait for confirmation that Robert and Durbe are ok.

Durberts knows Janis is a friend... :nod: he was just saying hello.. :wave:
But, 'wow' indeed! What a blow! And that it had to be that oak and not some other tree...what a coincidence.
Thanks Ame for the GIF. Great idea!

Wonderful to see Durberts from another angle, He has become a 'flying door', a nickname the WT Eagles are given in the Netherlands for obvious reasons. But probably they are called that in other countries too. Thanks, Janis, for the pictures!

Now we just have to wait. Hopefully we will see the birdies again soon!

You're right Ame :rolleyes:
We hope to have reassuring news in the coming days, it is comforting as Liz said that the moments before the devastation seems that there was no eagle in the tree oak :thumbs:

There are many connection problems with the Looduskalender website today, by the way. :bash:
No more connection problems :D

I also have tried to compare, but it is hard to tell what has changed, also because the cam view is distorted by the very wide angle. The central tree in your picture is gone for sure, but is there something missing to the right of it also?

If you look at this picture taken from the ringing video you can see better that there is a group of smaller trees closer to the nest tree. The same group - I think - that you see on the right in Janis' picture. Because of the wide angle the oak and this group look closer together than they really are. If you watch the video it is even more evident. Besides, if there had been more trees next to the oak wouldn't Janis have seen the remains?

By the way, is there a large bird in the tree far right in Janis' picture or am I hallucinating?
