This thread has been set up to follow the travels of Caledonia and Alba, the young ospreys raised at Loch Garten in 2012.
Their mother is “EJ”, the resident female at Loch Garten since 2003; there is some doubt about the identity of their biological father, given EJ’s dalliance with a male from a neighbouring nest, Blue XD, both before and after the return of her regular partner Odin, who raised them.
Caledonia hatched on 16th May and Alba on 18th May; they both fledged on 14th July.
This is a link to the Loch Garten blog describing the ringing and satellite tagging.
Caledonia’s ring is Blue/White AA1, reading downwards. Alba’s is Blue/White AA2, reading upwards.
Following the tracking
This page gives a quick overview of the routes on a map, which will be more useful once they start migrating.
If you want to look at the routes in more detail on Google Earth, this page contains instructions on setting up your PC to do this.
This blog contains some useful information about how the tracking works – we are now on a 3-day reporting period.
This is one of the places that Alba may have been hanging out

Tiger Signature
jsb said:I was looking closely at the area of the last fix (23rd), but had the suspicion of human involvement in her movement.
Yes but I feel something happened on October 20th and well away from her last resting place.
Tiger, I agree, I said something about that on the summary thread when the news broke. I now think she may have gone or been taken to 23rd fix, after an event or incident on the 20th. Richard's blog made me think all was not as it seemed, posed more questions, than provided an answer. Only my opinion.

Quesion is was she wounded on 20th and then somehow managed to get to the last recorded point? Or was her body with the tracker taken there?
Yes, that is along the lines of what I said on the other thread.
Quote from Summary.
"Reading between the lines, that implies some movement took place, following the degradation of the signal. So some incident, that seriously injured Alba, then resulted in the problem with the signal."
Hi all, just read the blog,and not been on here for a while, so im very shocked by what has happened to Alba and very upset, as she seemed to be settled in a good place. I dont think anywhere is safe for these juveniles. I really hope that Caledonia will stay where she is! Ireally hope Ceulan will have a better future and return one day to breed and Lewis too! I thought Alba would be one of the lucky ones, so sad!
There were 3 points on 20th, two of which were over the sea.

The one thing that tracking has taught us is that the adults stick to a very small range when they get to their normal wintering grounds. Now if that happens to be safe it is easy to see how they can have long lives. Although migration has its hazards adult ospreys usually survive it. Of course as always there are exceptions like 9 (98).

Yes but I think Alba had a habit of standing on those dunes around the island (Ile des Oiseaux).

Yes I think that incident took place on the island.
