Latvian Osprey nest 2017 - Tina & Teo

[Shanta]

My thoughts to Tina and behavior:
Behavior of Tina and feeding chicks was strange for me, but after seeing Tina has really problems, I can feel with her. In feeding she was very fast and suddenly stop it. Also Tina eat more of the fish than feeding and she did not feed so often as usual. The first days for chicks (nearly by humans and babys, only a little bit but often).
1. Maybe Tina is a young mother and must learn like every first Mom, to take more time and to be patient.
2. Of all the gagging, Tina loses a lot of energy and she need it for the chicks, so she self eat more than feeding kids. Also between all this not feeling well time and sleeping time, she feeds.
3. Just hatched young birds (like the third one) dont need so much food. They have a "backpack" for one, two days. Also the crop should normally be empty, before next feeding ... otherwise there is a danger of acidifacation of food. Sadly Tina with maybe health problems is often so tired, she can not give more
4. Tina is not feeling well and what ever it is, but she give her best. If we are sick, we do not want to think of food either

Think we must trust Tina and Teo in this time. Like yesterday, Teo feeds the chicks, it was so great and touching to see it! Sadly we can't send a Vet for health checking Tina.
This are my own thoughts and I'm very happy that last time with eggs and maybe chicks was wrong.

while we wait.. videos from yesterday. I did not make them into the forum because I thought Shanta is doing it.

Thank you Liz! Know you are faster than me, we "talked" about it. Sadly had no time to find out what is the best for me and also since some days YT is soooo slowly and not only during special times, always! My wish only, if you make or made a video, a short message would be very kind. Grrr, reads in English not very friendly ... but you know how and what I mean. So I have time to pick up raisins

If I get an answer of an expert and know more I'll post it ... but we have to wait and be patient.

[Shanta]

Shanta! Unfortunately, I don't have the time to observe life in the nest. Only weekends or evening. I would like to know when Tina has appeared these symptoms. Or maybe it's for her usual story...She didn't eat in the nest before hatching. Now Tina almost constantly before our eyes, and we see that she's got a problem. Birds have Pellets formed after 6-10 hours after eating. And, Yes! None of the nest of the osprey that I have seen, I haven't seen anything like it.

Gavril, think it's not important if she eats in nest or not. You are right, we could not see about all her behavior after a shift change. Maybe she had the same problems. Curious, she felt well for two days after casting a Pellet ... or maybe it was'nt a Pellet but it seems so and she did not eat it (like other things of vomit).
All is so strange and new, let's hope all is normal. In the moment it is hard to see Mom Tina with problems, but it was so touching to see Teo feeding the chicks and besides poor Tina with her problems.

We need the cam back, not knowing what is going on makes me

[Deli]

Gavril Really, I dont know. During breeding time (maybe missed it) have not seen it at Tina. Must be new and whatever it is, only from viewing on cam we can give no answer ... maybe an expert for Eagles/Ospreys. Still waiting for an answer and later maybe more.
Gavril, know there was one more question, sadly can't find it now

Shanta: I have also observed the behavior a few times and have gained the impression that something has settled with it (and a fish contains a lot of components, which can be determined) and that it tries to get rid of it. Unfortunately, this does not look like normal strangulation of indigestible ingredients. I hope she will recover by herself, but her weakness was clearly perceptible ...

I've found this article:
https://birdsna.org/Species-Account/bna ... foodhabits
But my English is not good enough to interpret scientific text and terms.

While we wait for the camera to be fixed, (fingers crossed), and see Tina and Teo & the chicks.
I know that this doesn't belong here, but I want to Congratulate Latvia on Ostapenko's beautiful win at the French Open yesterday, Sunday!!!
What A Match! <3

[Shanta]

I sent Urmas a message asking for pellets from Ospreys and Tina

Thank you, Urmas!

Here is his answer:

Thank you Shanta for your observation and videos!
Yes, it seems something wrong with this female Osprey in Latvian nest. I don't know what exactly. There may be some problem with digestion of food, what ever happens with animals, but rarely we can see the process. In general almost problematic birds in population simply disappear and therefore do not share their genes to next generations, only the most adapted individuals can have successful descendants. If something goes wrong in evolution those will be eliminated - maybe we can see that sample here?
I did not see Ospreys producing pellets at all, so it should be something extraordinary and probably connected to health of digestion. The reason may be also parasites Ospreys get of food? Good that male is feeding the chicks, but difficult to say if that is sustainable for brood.

[Gavril]

Thank you, Shanta and Urmas! Parasites - that's what I thought too. In any case, it is important that Tina and Teo were able to raise their Chicks.

[Cessie]

Shanta, thank you for the report from Urmas.
I'm thinking positive thoughts that Tina and Teo are successful raising their chicks.

[andi7]

In any case, it is important that Tina and Teo were able to raise their Chicks.

Unfortunately nature would prefer the opposite. As Urmas mentioned "In general almost problematic birds in population simply disappear and therefore do not share their genes to next generations". So if birds with bad genes procreate, the next generations of ospreys could be weaker or could become ill much faster.

[Jojo]

Missing this little family in the nest so much.... fingers, toes and eyes crossed for speedy reparation of the camara.

[Cessie]

Jojo, me too!
I have faith that the camera will be fixed soon!
I know that it rained in Estonia today, so it's possible that it rained at the nest site too. That is a possible reason why it's not back yet!

Latvijas Dabas fonds ​Rīt mūsu eksperti dosies uz zivjērgļa kameras vietu, jo problēmas ir tieši tur. Tad arī sapratīs, kā tās risināmas. Ziņosim par jaunumiem.

GT:
Tomorrow our team will go to the osprey camera location, because the problem is exactly. Then they understand how they solved. Escalation of updates.

Deleted, the same info, that Liz posted in her following post

Good Morning
Info fom DD Forum. Paldies Wednesday

Sazinājos ar Jāni Ķuzi un rītvakar ir plānots doties pie ligzdas. Ir divi iespējamie iemesli, kāpēc kamera pārtrauca darbību: 1) uzkritis koks uz kabeļa, kas būtu salīdzinoši ātri novēršama problēma un 2) negaisa laikā sabojāta pati kamera, kas nozīmē, ka jākāpj kokā augšā pie ligzdas, kas šobrīd, ņemot vērā cāļu vecumu, nebūtu tik ātri realizējams, lai neapdraudētu ligzdošanas sekmes. Tad ātrākais, kad kameru varētu atgriest pie dzīvības ir pēc ~ 3 nedēļām, kad varētu kāpt un gredzenot mazuļus.
Rītvakar noteikti būs vairāk informācijas! Tā kā gaidām un ceram!

Translation for Liz01:
I contacted Jānis Ķuzis and it is planned to visit the nest tomorrow evening. There are two possible reasons why camera stopped working: 1) a tree fall down on the cable, which would be a relatively easy to solve and 2) the camera itself has been damaged during the thunderstorm, which would mean, that they have to climb up to the nest, which in this moment, taking into account the age of the chickens, can not be done to not harm the successful nesting. In this case the soonest time when the camera could be repaired is about after 3 weeks, when at the same time the chickens could be ringed.
There will be more information tomorrow evening! Lets hope and wait!

Still, thank you for the information (that was here last night already), and for paying attention to other posts. You are very noble.

Hellem, I'm sorry I have not seen, that it is there already?
I was busy with the owls and was in the DD forum, as always. I saw the translation for myself and copied it here. I was so happy that it was in English.

Last information from chat by Maris:

MĀRIS ​Pēdējā informācija - Jānis Ķ. & Co uz vietas varētu būt ap 19-tiem, pēc tam vēl apstākļu noskaidrošana,..., tā kā jāgaida pats vēlais vakars.

GT
MARIS Last information - Janis K. & Co. could be on the ground about 19 o'clock, then another clarification of the circumstances, ..., so as to wait for the same late evening.

Liz

[Taube]

thank you for the Information
i hope i can see the Familie soon

From Youtube-Chat:

Ligzdas Gariņš​
Because of the weather circumstances his team did not visit the site (nest) yesterday evening. It was postponed for one day - to this evening.

[Shanta]

andi7, many thanks for info!

Shanta I'm reviewing all the literature on birds of prey in search of questions posed by Tina (And You, Shanta). First, a quote - Pellets of these birds were not able to find any under prasadam or under the nests of ospreys. It is believed that eating almost exclusively fish, it does not reset regurgitates, digesting fish bones and scales.

At the same time, we know that with a shortage of primary production that happens in the period of heavy rains when the water in lakes and rivers becomes turbid, the osprey is forced to catch frogs, rodents and even birds. It seems that with such foods must be freed from hair, feathers and the bones, discarding the pellets. The last paragraph, I think you can safely discard.

Another quote - Pellets regurgitates and many fish-eating birds, but not all. For example, specialized ichthyophagi — osprey, pelicans, cormorants — are able to digest fish bones and scales. Heron also apparently digest the fish completely.
We have not seen these symptoms, because Tina was more free before the arrival of Chicks. The fact that in addition to pellets, Tina throws and some secret, saliva or something else liquid. I really want to understand what Tina!

Thank you, Gavril! That is nearly the same what I also could find out.

In an article https://birdsna.org/Species-Account/bna ... bits#drink I have only read:
"Individuals regurgitate indigestible bones and scales in a pellet, as is typical of birds of prey, but these pellets are small and produced infrequently, suggesting that much of consumed prey is digested and absorbed through the gut."
Thank you very much, Deli Forgot to post this Link
Garil, read also Ospreys Pellets are seldom and mostly soft. Sadly can't find again this Link.

Today I found a video where I was searching for, Ospreys and Pellets. It looks nearly the same as with Tina ... or not? There also some more things flew out.

Here another video with an Osprey chick and also a Pellet, it looks to be an easier way.

Let's hope, Tina, Teo and chicks are strong and healthy!

[Cessie]

Thank you, Shanta and Gavril,
Yes, let's hope and think positive thoughts, for Tina!
Waiting for the camera to restart!!
