The team are off to The Gambia on 7/1/2014 and Tim's latest Blog gives all the details. Watch this space.
Birdies LG DU update.
Now these birds are very smart and am sure they do know that an egg is not viable.
In the case of Rutland the female must realise that she can not leave these eggs for hours and still have viable eggs.
Just wonder if they sit with the thought - In frustration - This is my nest.
Just like a tree thats planted by the water.
I shall not be moved.
Thank you Keith.
Emma's Blog of that time explains the possible causes of failure due to exposure to cold etc.
The original question is answered in that the birds were still sitting up to the 7th of July.

Oh the Manton Bay nest in 2008. 8 (97) went missing for a day or so and the eggs failed to hatch. They went on sitting for about 70 days. See page 65 of Rutland Ospreys.
Although a red tailed hawk rather than an osprey, Pale Male's nest failed in 2005, 2006, 2007, 2008, 2009 and 2010. That is over a year of sitting on duff eggs.
Then the female Lola was killed in 2010 and with a new female there were chicks in 2011 and every year since.
Of course the opposite has happened too. The Dyfi nest was thought to have failed in 2011 but all the chicks hatched although late.
In 2007 the DPOF nest was thought to be going to fail but produced two chicks at the end of the day.
However no nest at the early stage can succeed without both parents.

Thank you Tiger.I just knew you'd have some info!.
Blue ringed bird (I think it is Blue 28(10)) on the nest alone at the moment, turning the eggs and now calling. He is I think trying to incubate, but is flapping his wings and calling. Not sure it is aggressive mantling or not.

He keeps looking at the eggs, but is keeping an eye on all around him.

It is Blue 28(10) Sheila.
Yes, I realised that after I had zoomed in! Nice to see him back.
Oh, he so wants to incubate, but it so wary!
