Iiris has been panting, apparently the temperature is high. Ivo sits on the tree to the right, tall and slightly curved with few branches.

There is a special term for birds for this "panting" - - - it is called "gular fluttering".

Explanation with a wink :wink:

And a scientific publication, a bit older already (accepted for publishing in 1967) and focussed to Cormorants, Pelicans, Owls and Doves, but it is the same behaviour for thermoregulation that we see here on the nest.

That's not possible. Somebody must have said something a little ambiguous.
The energy that birds need to fly thousands of kilometres is not available without food. They do not have this stored in their bodies as reserves of energy.

Yes I was very surprised, it does seem strange and impossible.
He said he based this idea on following their Osprey with a very detailed transmitter, which gave information to lead him to believe that the bird only stopped for short sleeps.

But who is to say it didn´t catch a little fish in those stopovers ??? :nod: :laugh:

Jojo :hi:

I am not up-to-date with this --- where are the wintering grounds of Spanish ospreys? They live much more South than ospreys in the Baltic states .... so maybe the distance they have to fly to get to their wintering grounds and back may be much shorter.

The bird in question went to Casamance in Senegal.

The project was started in 2013, bringing around a dozen Osprets from Scotland.
After migration only a few have ever returned to Urdabai Bird Centre.
All males, so no Basque Osprets yet!

Thank you, Jojo :thumbs:

Fingers crossed, that time will bring more success for this project :2thumbsup:

:?: :arrow: Did some of these "exported" osprets pop up in Scotland?

Well, that's an interesting thing. Hard for me to imagine without fish. But what Bea wrote (the flight distance), is a good consideration...
Isn't it the case that the Estonian ospreys with transmitters always take longer breaks on their journey, namely at water points with fish stock? Or am I mistaken, does anyone know?

21:28 Iris landed with a halfeaten fish but flew quickly to the dead tree with her fish
21:57 It's almost dark, Ivo is still incubating and Iris is sitting on the dead tree

22:11 It's completely dark now, Ivo is still in the nest

Thanks, Bea - very interesting. It seems they do both panting and gular-fluttering. I'd never heard of this before.

Good morning on a rainy day. Ivo was protecting the eggs and Iiris just came back to incubate.

Iiris incubating, Ivo pays her a short visit. To me it looks as if he'd like to incubate, but Iiris stays on the eggs.

Oh, I just read, there are three eggs now. :loveshower: Congratulations, the ospreys on this nest are doing well, it seems.
