LOCH GARTEN - May 2022

Telyn doesn't seem to start full time incubation till 2nd egg appears at Dyfi.

I've read of that before Richard, but EJ/Odin were always incubating from first hatch so it is unfamiliar to me. More worrying is Mistle's sudden aggressive attitude toward Axel who was doing no harm! I do like to see the best in folk! He has been such a sweetie today, taking to incubation so well (I was going to say like a duck to water...).

And after all that aggression, and fish, she is food soliciting. She can't be hungry after that huge fish!

I'm sure CRinger has come across this several times before.

Smiles. Indeed I have - in Henry's day when he kicked eggs out and to the side of nest. We consulted 'the guru' RD. His view was this. The core of the egg needs initially to rise to a certain temperature for development. This has certainly happened this year - it has been incubated overnight. Once this has happened how long can an egg remain uncovered before it loses its viability? The answer is not easy. It is tempaerature / weather dependant. If it is snowing the egg will cool much faster. Similarly rain will not help, nor strong winds. On a day like today my best guess would be the egg would need to be uncovered for AT LEAST an hour before I would start to get seriously concerned about its future.

While we are reminiscing, I found this video of EJ, Odin and chicks from 2013.  Odin has brought a fish for the chicks, and spots another fish which has fallen to the outside of the nest.  He retrieves it and claims it for himself.  A lovely insight into the daily lives of our famous family. www.youtube.com/watch.  

I remember that so well. It happened again recently. I was going to refer to it but didn't spend enough time finding out, and the moment passed. EJ was the culprit and although she tried, she was unable to retrieve the fish. Thank you WATTLE for the memory!

After all that - there's no doubt that THEY can see the egg - even if we can't!

An extra hour or two shows just that, CRinger! Mistle is happily incubating in the evening sun! Ospreys know best. BUT, why has she been so aggressive towards Axel today, perhaps not for the first time??

I missed the aggression. Has someone posted a video so I can have a gander?
