Tracking Oighrig, Breagha and Caledonia

This is a new thread to follow the travels of these three young ospreys from the Loch Garten nest.

Oighrig

This male juvenile is the elder of the 2013 brood, hatched on 25th May and fledged on 16th July.

Oighrig’s ring is Blue/white CF5

Breagha

Also male, the younger of the 2013 brood, hatched 28th May and fledged on 19th July.

Breagha’s ring is Blue/white CF4.

Caledonia

Hatched on 16th May 2012, fledged on 14th July and left Loch Garten on 19th August.

The travels of Caledonia and her sister Alba were first followed in this thread, now closed. Caledonia is the first juvenile osprey tracked from Loch Garten to settle in Europe; she has been living on the northern outskirts of Seville for nearly a year now.

Caledonia’s ring is Blue/White AA1, reading downwards. LG blog on the ringing and tagging of Caledonia & Alba.

    LOL!  I still think of them as Wotadin and Moffalot - I think they're two of the most entertaining informal names fot the juveniles in recent LG history.

    I agree with you Clare. Wonderful names! :)

    The next question - Whos gene  implants migration into the juvenile Male or Female or is it not like that.

    That's an interesting question.  You'd have to track both parents and a significant number of their offspring to find even a part of an answer to that one.  Looking at Caledonia, for example - there's a very strong probabillity that she's the daughter of Blue XD, and he's an African migrator if I remember correctly.  I wonder if the birds inherit the bare bones of a migration route, with the fine details left up to the individual bird to decide for themselves.

    Our herring gulls are red listed birds.  Think about that the next time you hear some flaming idiot calling for a cull of them.

    Clare - I was thinking exactly the same thoughts of your last sentance - maybe we have now opened a discussion :):).

    We don't know where either EJ or Odin migrate to so it would be impossible to say whose genes go to which chick in that family.  We've seen both Alba and Oighrig make very fast migrations to Africa - does Blue XD do the same?  Both Clare and I have been wondering if EJ migrates to Spain as this might explain why she's such an early returner for a female bird, but if Alba and Oighrig inherited her migration gene then all it might mean is that EJ is a fast migrator as well.  I'm only guessing at all of this.

    Tiger posted this link on the LotL thread to Paul Wildlifewriter's latest blog, which explores Blue YZ's migration and her inherited weather sense - this is a really interesting read.

    Morning friends! It's a really interesting debate. I have also wondered whether their different attitudes to migration might be in any way linked to their paternity but I don't think there is any evidence that this is how it works. If you take Leri, Einion and Dulas from Dyfi in 2011, there was no doubt about the same paternity but their migration patterns and end destinations were not identical.

    I read Paul's blog yesterday, which was fascinating and would explain a lot in terms of how birds navigate their way South and back.

    PS I was doing a bit of Google earth streetwalking (after June Spradlin on Gabfest explained how to do it!) and here is Chapelle sur Loire, one of the places that Breagha has recently been lurking in! Croissants with your morning trout, anyone?

    On the subject of inherited genes, it would be interesting when birds are tagged or ringed to keep a feather or do a beak swab to get the DNA code for that bird. Also at the end of the season, nests could be raided for lost feathers. In this way a profile of the populaton could be drawn up & quite a lot of information gathered on who inherits what from whom.

    Maybe they already do it. Not so costly as satellite tagging either.

    IMHO it would be so interesting and informative that the cost must be prohibitive, I can't think of any other reason for not doing it - the disturbance to the bird would be nothing compared to being ringed or tagged.

    The DNA would certainly be interesting, and valuable information too. I do know that Bassenthwaite used to keep a feather at ringing time, but when asked about results said it is too expensive to analyse. I wonder whether other osprey projects take a feather, you would think so. It would make a super research topic for someone. Analysis of DNA is geting more widespread so perhaps the cost will come down in time and surely it will be done then.
