[IceAge]

Hello ,

14:28
some wings exercises

[Bea]

... 7:49 daimar just expelled a pellet right in front of the camera.
I don't remember seeing or reading about pellets in the past. probably my memory is off.

I made a slow-mo video of that moment



Hardly to see - this is the pellet

[Hellem]

16:59 Ivo lands with a nice still alive BIG fish , Irma takes it and starts feeding Daimar, Daisi is waiting
17:21 Eating - feeding is over, Irma fed both kids
17:22 She flew away

17:23

[Hellem]

17:22 - 17:24 The very serious wing exercises by Daimar, he jumped (flew) over the nest and landed on the nest rim

17:32 Daisi's wing exercises

17:51 Again Daimar

IceAge , you saw it too, Daimar was very brave

[Cessie]

and thank you, Bea!
The slo-mo video of the pellet.
I'm glad that you saw that it was Irma with a stick, and not a confused Osprey.

18:53 A very nice headless fish from Ivo , Irma begins eating and feeding Daimar, Daisi is waiting

We can make bets who will be the first one to fledge - Daimar or Daisi

Daisi is a whopper compared to Daimar - and will be the last one to fledge when she continues consuming fish like she does ... mostly always the first one who wants to be fed ....

I saw a pellet regurgitating here in Latvian osprey nest yesterday, on July 22, too

You are right Bea, Daisi is a Whopper because of her constant eating. In my opinion Daimar is the first one who leaves the nest to be independent.

Thank you Bea and lianaliesma for showing this. I never seen this before.

There was a Goshawk on the nest

Irma had just come in with some moss and shifted a stick when she took of like a rocket and a Goshawk landed at the side of the nest. Daisi and Daimar were flat - and the Goshawk took off immediately again. Irma returned up to the cam support and called alarm and warning for several minutes



Slow-mo video

[Bea]

Irma had just taken off in fear and the Goshawk landed at the side of the nest

[Bea]

[Bea]

But we still have our two osprets on the nest .... maybe the Goshawk was "only" interested in Irma???

[mogga]

Strange situation at 22:26.
I don't understand the scene.
Irma is leaving the chicks alone with a foreign bird?

I think it does not happen very often that ospreys cast pellets - usually all parts of fish are easily digestable for them.

Urmas answered a question about ospreys and pellets in topic of Latvian ospreys:

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.

One can find more interesting infos about ospreys and pellets in some posts later there, forum members made some research:

It was an attack from a Goshawk and I suppose Irma left her osprets because she knew she would have hardly a chance against a Goshawk - and it looks as if the Goshawk wanted to catch Irma and not one of the osprets

[mogga]

@Bea:
I saw that. Isn't that a strange behaviour by Irma?
I wouldn't have expected that...

[mogga]

@Bea:
Oh, I see. My god, what a lucky end of the story...
