Black Stork Nest in Karula 2019

[Anne7]

12:56:42 Karl II preens his chicks


12:56:43 The youngest chick is still a lot smaller.
Well, the other 3 grow very fast.


13:04:27 Kati comes home

[Anne7]

13:08:40 Feeding by Kati. The regurgitated food doesn't look very appetising.
Oops, #4 is in the back.


13:09:01 It manages to crawl to the food and eats.


13:10:46 All chicks have a big crop.

14:12 Kati offers frogs for lunch.

...We don’t yet understand all the many functions of yawning....

Thanks, Solo

[balistar]

Many thanks also to Anne & Liz for the reports and beautiful pictures

Very nice feedings and a joy to see the youngest doing so fine.
If the small #4 is further eating so well, it will soon reach to the size of the others, won't it ?

yawning birds :
Experiments with Budgerigars indicate that yawning can serve as a thermoregulatory behavior; the birds yawned more frequently in warmer conditions. Experiments with rats seem to bolster the conclusion; their yawns may be preceded by spikes in brain temperature and are followed by cooler readings.

It is also assumed that it is a social behavior .. contagious yawning, as in humans and mammals

My opinion is that "crop drop" is not proven. You can not find anything. Only with the American Bald Eagles.
So it may be, that something is being interpreted by bird watcher.

I can not imagine that the food in the crop can only reach the stomach with a open beak.
And of course it's clear that pellet can be cough up only with an open beak.

Thanks also to you, Liz.

Maybe there appeared a sort of misunderstanding.
Actually, I did not want to know why birds yawn, but it's very interesting to read about it. Thanks again for the informations.
I only wanted to know, if that what the storklet did on the mentioned picture, is a "yawning" or a transport of food. (in this way i also understood the question of Owlie). I thought it was yawning. From the answer of Solo i understood that it was transport of food, what the Americans at Bald Eagles call "crop-drop".

"And of course it's clear that pellet can be cough up only with an open beak."
There was no doubt about that.

Maybe i did understand everybody wrong - then i apologize.
Better, i don't ask or write nothing anymore.

There are 3 options described, which is why the beak is open.
1. yawn
2 food transport
3. Cast a pellet
That's why I mentioned these 3 options

I have kept it general .. It does not refer to what Owlie and you wrote. I've known this "crop drop" for years, and have already asked questions about it elsewhere - even years ago I already tried to figure out if that was just an assumption. I was told that it is not proven.. Birds do not all have the same digestive system.´BTW: .. Bees also have a crop

In order to prevent future misunderstandings, I will not write here anymore. It is really too exhausting for me.

[Solo]

...yawning birds : ...

I read also that - to me the conclusion ist:
...We don’t yet understand all the many functions of yawning....

[Solo]

...Better, i don't ask or write nothing anymore.

nooo
only asking and searching the answers help us to understand better what we see on nests

my answer was about storks (we discussed about that year ago and in that time I read that)

[aquiline]

Many thanks to all of you for posting all these wonderful pictures and videos. I am so happy that little one is that strong and tough and determined to get food. What a brave storklet

And Karl II is a wonderful father and very careful. I don't think that these are his first kids. He seems to know exactly what to do and is paying attention to every little bobblehead

[Owlie]

About yawning,

it was not my meaning to open a sensitive quarrel. I tend to believe, too, that the exact conclusion doesn't exist, we simply don't know what all that yawning means. Maybe they just burp when we see "yawning" ...

16:58
After all having eaten, the parent (EDIT: Karl II - thank you Liz at YT) drew out the big fish or lamprey from #4's mouth, as s/he couldn't properly swallow that big food.

Hello

i'm still happy to see any picture with the youngsters' beak full of food - because in the most cases when i see them being feeded, the youngster stands either a little apart or in the back. and untill the youngster is active enough or the way is free for food, the others and adult have already eaten the most and the feeding is over again :(
so i keep my fingers crossed and hope everytime it's enough for a big meal ! :)
thank you for pictures with full beaks :))

edit: forgot to send my reply

So in the meanwhile they had e.g. another feeding - and i was at first happy because the youngster got a real big meal :)
here is a video of it: https://streamable.com/cw5mt
at the end of it, you can see the S-form in the throat and still the tale of it outside of the beak - maybe the meal was a little bit too much...

but worse - and i've not thought of this possiility and closed the video too early - the adult came and helped by pulling the whole good meal out of the little beak and body and ate it by himself...

[visit]

yeah :)) now the youngster had a really big meal

[Owlie]

I think Karl II did the right thing by pulling that too big food out of #4's beak - s/he could have choked with it otherwise.
I have seen once when American Bald Eagle mother Harriet rescued her spouse Ozzie by pulling out a far too big pelt (if I remember correct it was a goat pelt) from Ozzie's throat in the same way. Birds are sometimes very clever and logical in what the do - by this I mean Harriet, not Ozzie

And BS parents pick up all food that is not eaten by the storklets and provide it in the next meal again.

Hello Owlie :)

Of course i don't doubt about the sence of pulling it out - i had only hoped, that it would have been a good big meal ;)

Kati was standing in weird postures, today.

16:28:24 Sleeping.


16:32:02 Dozing

16:49:38 Karl II comes home


16:51:46 He wakes up the chicks. #4 tumbles on his back.


16:51:48 Karl II starts feeding. It looks as if the youngest fell asleep.
