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.

That point on 23rd October is presumably where the satelite tag ended up.
Now Alba either flew there or the satellite tag and her body or the satellite tag was taken there by a third party.
Tiger Signature
In case people missed it the body of a juvenile osprey with a satellite tag was recovered in Louisana recently. The cause of death could not be determined.
What about as somebody suggested and crocs or would they not be in that area and is her point on 20th too far out for them.
If it had been a croc wouldn't the sat tag be inside it? I imagine something the size of an osprey would have been snapped up and swallowed whole.
Yes, fishing nets and boat is an interesting idea.
ChloeB & Tiger's Osprey Data
What goes in must come out i just dont understand how the signal disappeared for two days. Unless the nets were in the water that long and being dredged along. Her demise is certainly very interesting.
I saw that yesterday Tiger and the thoughts that the salt water could be causing a problem. As Alan suggested hopefully there are more out there alive that are presumed otherwise. I really am gutted for Alba. Also anxiously waiting an update for Roy's birds.
I wonder how regular a croc's bowels are? A typical nurse question that, and I should know! :)
I felt that the picture of Alba's last position given on the main blog was too close. So I have now made a wider view.
It is very hard to see how Alba got there by any method other than flying.

Yes but there are not a whole lot of ospreys turning up with non functioning transmitters are there?
What distance inland are we looking at there? Yes it looks quite a way doesn't it?
