Loch Garten osprey diary

The ospreys at Loch Garten have people across the world gripped in their tale of violence, adultery and... well... fishing.  More...

100km...

...is about all that's separating Mallachie and Rothes.

Since 12noon on the 19th Rothes has mainly been dodging about the northern part of Guinea Bissau, with a brief hop into Sengal. On the 19th, 20th and 21st (last night) she roosted close to Varela - maybe becoming a favoured area? That's where she was at 6am this morning (22nd).

Mallachie meanwhile has continued her migration. She continued SW and reached The Gambia at 11am on 20th (Tuesday). She then turned more to the W and followed the Gambia River downstream, roosting close to Jarreng Tenda on 20th. Yesterday saw her continue SW back into Senegal. Last night she roosted near Djinaki (which is where she was at 8am this morning, the latest point I have for her).

So this morning it was only about 100km between them - will they get closer?

For those of you asking about frequency of updates - it's my understanding that we'll get hourly data and so daily updates until the end of October. From November the data fixes will be reduced to twice a day, with the data available for download once a week - and so weekly updates - probably on a Friday, with missing data added in on Mondays. At some point in the spring the data will go hourly again for a bit, then over the summer it'll be back to twice a day. This will continue for up to 3 years.

More tomorrow.

Thanks again Alice.  You deserve a medal.  Good news about Mallachie and Rothes.

Also thanks for the info regarding frequency of updates.

Thanks Alice for the good news. It is amazing that R and M are so close after flying all that way on different routes and at different times.

Thanks Alice - it's absolutely fascinating what we are learning about these birds, and it's going to continue :)  If by any chance you discover that they have 'met up', then I think that you had better put a health warning at the top of your report - I fear that a good few of us may get over excited.

Thank you Alice. I would so love to hear that they have settled in the same place.

Alan, I so agree with you. If birds laugh, then they must be quite hysterical knowing that we actually know so little.

Thanks Alice. Absolutely incredible they are so close having flown so far.

Thanks Alice for the latest info.  Can't believe they are so close.  What a fairytale "migration" ending it would be if they came together.  There must be hundreds of ospreys within their areas but I bet they would know each other - "I've seen that aerial somewhere before"!!!  So close and yet so far at the moment. x

Good grief. Amazing  - thank you Alice, and for clarifying the update info

Thanks, Alice ... great news that all is well and that they are so close to each other! Thanks also for the info about future updates.

OMG - what amazing, wonderful news!  Thanks, Alice, you're a gem.

Wow what fantastic news Alice, imagine going all that way at different times, on different routes and now they are only 100km apart. It would be wonderful if all three sisters could meet up and be together for the next three years. I wonder what the likelihood is?

Thank you for keeping us in the link Alice about the future update!

That is amazing  news Alice!! ......... how we all want them to meet up and recognise each other :)

It looks such an ideal place to spend 2 or 3 years, maturing in the sun and lots of fish to eat.

Thank you once again Alice for keeping us up-to-date on our birds' progress.  If they do meet up (which we will never know for sure), I wonder if they would recognise each other? - again something we will never know but just so long as they are thriving that is the main thing.

Thanks for that Alice

Technology is a wonderful thing, I await the next instalment with bated breath will they get closer?

Imagine them so close considering how far they have travelled.  Wonder where Garten is now??

Thanks Alice.

Alice, thanks so much for the diary today - good news indeed.

If it is a genetic predispositon which has brough them so near, I guess there is a good chance that Garten will be nearby too!!!  This is just the kind of information we are looking for.  Well done the techies, Roy Dennis, EJ & Odin and the girls themselves for bringing this to us all - and of course all at Loch Garten (and Tesco's, without whom at least one of them would probably not have survived to migrate!).

Thanks Alice for all the wonderful information about our girls.  Alice, I was thinking that the batteries would not last so long but you said that the transmissions could continue for about three years.  WOW  No wonder the trackers are so darn expensive.  What happens then?  Does the bird continue to wear the tracker indefinitely?  Thanks again to the Team LG for all you do.

Still impressed that you can sharpen a chainsaw.  Dang.

Cheers Alice so 80 miles between them .. could they possibly know each other if they get very close, one thing we will never really know whether they recognise their siblings at all once they've left the nest

Oooops I think I typed 80 miles that should be 60 miles .............

WV sUSAn, the tags are attached to the birds by string/twine (can't think of the right word) that degrades over time and eventually the tag will fall off. The tags are solar powered as well.

I think that is right but am happy to be corrected.

It's all been said. All I can add is a very contented smile.   :)      

Thank you Alice.

Thanks again Alice. Will they meet or not!!!! who knows!! maybe it is destined that they shall meet up again somewhere.

Great news Alice. Thanks a million for your daily updates. We are soooo spoiled!

Grateful thanks from me too - I note that neither sister is too far from their half sister Nethy's last known whearabouts. Can't help wondering where EJ might be..............

I'm going to ask my first question here and I'm sure it has been said already so please forgive me but

what is the final destination of our girls please ?

Annette in SoCal
Posted on Friday, 23 October 2009 at 5:35

Kittenface: Welcome! Rothes is already in the general area of West Africa - Senegal/Guinea Bissau - where she'll probably stay for the next three years. Mallachie is approaching the same area and may well be there by the time we get the Friday update.  Have you been following them on Google Earth?

Mike
Posted on Friday, 23 October 2009 at 8:36

WV sUSAn. I think you'll find that the 'tags' are solar powered and I believe they can be controlled, ie: switched to different signal programmes, via the satellite. The process is designed to allow for accurate locations on the migration runs but of course once they are settled there is no need for such detail. The harness which secures the unit is, I believe, secured so that it will only last for the period mentioned and then fall away. I'm sure the 'team' will comment when time and duties allow!!. Mike

I see that our two girls are very close to each other! How wonderful is that! :-)

Alice, belated thanks for this latest information.  Wouldn't it be interesing to know if their genetic programming is so accurate that it will take them to the same area, perhaps where EJ or Odin overwinter?  That could mean Garten would probably head there too.  Bet someone, either at LG or 'out in the ether' will be able to answer that!

Thanks again.  Great to know the girls have made it safely to the wintering area. I'm following the news though not posting much.  Just going off on holiday.  Scotland but not, unfortunately, LG this time.  Will keep eyes open for eagles and deer on Mull.
