I hope all 3 chicks do well Starling.   I think they did that at Rutland one year, put a chick in another nest, it was a while ago so cannot remember the details. 

It was when 08(98) disappeared (feared killed) while 5n(05) was incubating.  The eggs were taken and incubated. One hatched and was placed in AA/AW(06) and the Scottich female's nest. £ of the 4 chicks were raised.  They sent DNA samples to check which but I never saw a result.

Thanks Hilary for that info

Roy Dennis has just published a new book today, entitled Cottongrass Summer, and not an osprey in sight!  £9.99

"A collection of fifty-two vibrant essays to inform, stimulate and inspire every nature lover.

Through unparalleled expertise as a field naturalist, Roy Dennis is able to write about the natural world in a way that considers both the problems and progress in ecology and conservation. Beginning with cottongrass, whose snow-white blooms blow gently in the wind across the wetter moors and bogs, this is a year-round trove of insight and knowledge for anyone who cares about the natural world – from birdsong and biodiversity to sphagnum and species reintroduction."

As this thread isn't used as much this season, I have extended the date through to February 2021, it is a thread worthwhile having though as somewhere to post odd bits and pieces.    

Then next season a new yearly thread can be opened then.  

Very sensible, Mary. Thank you.

Does anyone know what is the oldest a juvenile has been before taking off on their first migration?
