It could have been their final departures, I believe.

They are old enough to leave the nest now.

Today, Päike and Karula are both 86 days old (12 weeks + 2 days).
Päike made her/his first flight 16 days ago.
Karula made his/her first flight 15 days ago.

Maru is already 'on the road' for 10 days! :slap:
He/she started his journey 9 days after his/her first flight.

We will see.

It seems to be the last picture of this season with Päike and Karula together on the nest. 8-)

They may return today as well and the last one who leaves the nest must be Karl, who will do general cleaning.

Has Karula ended the season as junior boss?

It is so quiet now in the Karula forest. You hear ... nothing. :unsure:

But Karl and Kati are very experienced hunters*.
I suppose they know how to swallow a perch. The difficult part could be to turn the perch in their crop, in order to regurgitate it 'head first' again ? I don't know if (and how) they can do it. :puzzled:

*We have seen that Kati grabbed a living viper right behind the head, so it couldn't bite her.

Hi Anne7

As you say, they are experienced. Hence, they may let the fish turn by itself, in case they plan to regurgitate it. By releasing the pressure of the crop walls may let the perch try to escape, and somehow the fish might know which way leads out. When it has turned in that direction the BS could increase the pressure again and suffocate the fish. This convenient combination of animal behaviour is, of course, result of my imagination only and lacks any scientific basis as far I know.

Anyhow I have made that observation, that a perch really tries to escape immediately when a fisher releases hand pressure around it, even slightly. Having dropped to the bottom of a boat it seems to search way to the direction of more fresh water there. On the other hand, the BS as a species may have developed such cognitive processes, which allow them to reorganize their crop contents depending on whether they plan to consume the food by itself or regurgitate it. If they want the fish back out again, they might swallow it alive, otherwise they might kill it by their beak. Who knows how practically intelligent these late born feathered dinosaurs really are ... :unsure:

Hello to the quiet forest :wave:

Päike and Karula... they left from the nest at a little bit different time, but can they' still flyes together?
How soon will the Bird Map show that they have really left?

Karula looks so thoughtful and determined in that 12:33:57 "boss"- picture.

Hello :wave:
Urmas will let us know. But everyone can update the birdmap themselves by reloading the page. Of course, the data must be released.

There is only data of Maru at the moment visible at autumn migration 2018.

Maru started migration just before noon yesterday and spent last night in Murmastiene, Latvia - quite close to our Latvian colleague Ugis Bergmanis. Will inform him about!
New data after six hours, hopefully.
But maybe there will be a stork in the nest .... :unsure:

Hello, kuhankeittäjä

About bird crops, wikipedia says this:
"Birds: In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esophagus. As with most other organisms that have a crop, the crop is used to temporarily store food. Not all birds have a crop. etc..."
https://en.wikipedia.org/wiki/Crop_(anatomy)
Although the crop is a muscle, I have no idea if birds can "control" their crop.

For the brave among us, here is an interesting scientific paper about the "Avian crop function":
"...The avian crop plays a major role in feed storage and moistening, as well as functional barrier for pathogens through decreasing pH value by microbial fermentation. Moreover, recent data suggest that this gastrointestinal tract segment may play an important role in the regulation of the innate immune system of birds. ..."
https://www.researchgate.net/profile/Ba ... ion_detail

And here is an expert explanation about "Regurgitation"
http://ww2.rspb.org.uk/community/wildli ... 89496.aspx


It is funny that you called birds "late born feathered dinosaurs". 8-)
This is something I intended to talk about on the forum, but it never seemed to be the right moment.
Birds, crocodiles and dinosaurs have the same ancestors, called archosaurs, some 240 million years ago.

"Crocodiles are the closest living relatives of birds but compared with their feathered cousins, they are stuck in the past, new research has shown. Both groups share a common ancestor that lived around 240 million years ago and also gave rise to the dinosaurs. But while the evolution of birds has flown ahead since the extinction of their dinosaur forbears, that of crocodilians has crawled. ..."

@Anna7 und @Treia :D If Velociraptors today have DNS successor, then it must be storks.

It looks like our Black Storks have actually flown off. It is so quiet in front of the camera. :rolleyes:

Maybe this is a good time to remind the fundraising. :D

Many many thanks to all who already contributed! :2thumbsup:
We already collected 3566 € !

This fundraising is a perfect opportunity for all of us to express our gratitude to Kotkaklubi and to give them a little help!

https://www.leetchi.com/c/support-these-wonderful-birds

In order to support Kotkaklubi, we had the idea to write – and illustrate – a popular, yet factual book about the life of black stork Karl. We have put a lot of love, time and energy into this book. A test-reader said: “It is a well-written story full of adventure, interesting facts and lovely illustrations.”
We really hope you will enjoy it too!

Anyone who donates 10 € or more will be rewarded with a free copy of this digital book.
It contains 129 double pages (spreads) and many really cute illustrations from Orinpix (Kaori). 

Here is a little preview:

For the first time, the nest is empty at night. It rains heavily.

Dear Maru, Päike and Karula, I wish you all three a safe journey.
Take care! May you live long and be happy.

Dear Karl and Kati, please come back next spring!
We are waiting for you.

Dear Maru, Karula and Päike! Favorable winds, much food and remember - we will be
watching you and our good wishes will follow you wherever you fly. Thank you Urmas and your team, for making a new nest next to the collapsed old one and giving us the privilege to watch this marvellous family. And thank you all with whom we have shared our joy and worries. I love you. :wave: :D
Kati and Karl - we'll be waiting for you! :loveshower:
