Satellite Tagging

  • No vespa it was not roy dennis, but someone I know very well who has been working with BOP for a very long time, and he has used them although he did not agree with them, because of there longevity. Jan

  • In September 2002 there was probably the most dramatic tracking of a juvenile ever. I know her as SSK and she was blown out over the Atlantic ocean. Nothing more heard of her until 2008 when Roy Dennis revealed that she was alive and well and nesting at Aberfoyle.

    I later worked out that she is an auntie of Nora and also an auntie of a lot of the Rutland birds that are so good at returning. Furthermore her mother was a Norwegian osprey. Juveniles do carry trackers and return to be adults.

  • The story of Mirja from Finland here

  • patily

    Can anybody tell me please, whether there is any further particular data that it is hoped will be gained by further tagging of youngsters? When was the first tag used on a young bird?

    In the UK the first juvenile ospreys were tagged in 1999.

    Tiger,

    Don't forget 06(01) satellite tracked as a Juvenile who returned and bred at Rutland, another exceptional bird that "broke" the rules.

  • Here we go more smoke to cover up what really goe's on. Jan

  • VC  No I have not forgotten 06 (01)  who nested at Rutland in 2003 as a two year old and raised two chicks. However 06 (01) did not return in 2004. No fault of the tracker there as the tag had already fallen off.

    The chicks did not return. The father did return in 2004 but not in 2005.

    In 2005  eleven chicks were translocated to Rutland Water but not one of them was ever seen again as far as I am aware. Not one carried a tracker.

  • Jan,

    I have no reason to "cover up" I just don't believe it's a black/white good/bad situation. I would love to hear facts from both sides of the discussion.

    I to have concerns especially surrounding harnesses coming away from one wing but not the other. But I think that tracking mearly highlights the horrible losses suffered by Juvinile Ospreys and as can be seen from the above examples tracked Juvinile Ospreys do return. possibly at the same rates as untracked birds.

  • Tiger thank you and RW do seem to have a strong Gene and was it you that said if an Osprey multiplys by one then a success. I do remember but not sure who said it :)

    I do have serious concerns on tracking and I have been vocal and no way do I want to push my views on others as we all should make our own minds up. I have spoken out too much but at least people now are listening to peoples differing views and concrerns and not arguing.

    We will never all agree but to have a discussion without falling out is good.

    I am going to try to stay away :)

    Thanks for the info Vespa and Tiger.

  • So are those people calling for a ban to tracking going to advocate the same for all birds?

  • B&B,

    A discussion is putting your thoughts & facts forward whilst listening to the opinions of others, hopefully you'll not stay away but continue giving us your information & take in ideas from others.

    It's when it become an argument and we fail to listen to different opinions that we have problems

  • I don't know that an outright ban on all tracking is called for. I think most of us agree that tracking of adult birds seems to have less adverse effect - for whatever reason. I remain unconvinced, however, that the benefits of continuing to tag birds as chicks - at least by this particular method - outweigh the possible detriment to individual young birds.

    I very rarely disagree with you, Tiger, but on this occasion I think we'll have to agree to disagree, and respect one another's views.

    So are those people calling for a ban to tracking going to advocate the same for all birds?

    Well, speaking for myself, yes, I believe I would support such a ban. I dislike interfering with nature, even when it is intended for scientific purpose. I cannot believe the wearing of the harness and tracker is in each individual birds' best interest, and that is really what it boils down to. Each bird has the right to live out its life as naturally as possible; in this opinion I am not anthropomorphizing, but perhaps leaning towards more of a Buddhist philosophy.

  • Tiger, I will answer your question, if no-one else will because you are very good with words:) and mostly  no tagging.  Red Kites have been seen to have serious lesions from the harnesses. Too many different species are tagged and I need to find one that is justified.

    There is the Cuckoo project as they are declining but not convinced either, if it does put stress on any bird.

    Do not get me wrong I was an avid follower and admit it and was on the fence but I will never lie and always honest. I just want evidence to say that these trackers are not doing harm or putting the Ospreys in danger as the stats are terrible and I know the percentage is not good for return, I think it might be lower than 20% and I am probably too high there. I should write things down but have a decent memory and do remember and take a lot in as I am interested very much.

    One film I did laugh at and funny was "Happy Feet" and in a dance sequence you can see a penguin with the tracker and back pack just like the Opsreys, honestly it is true. I will need to find the dance :)

    I need to go as need to cheer up.

  • Vespa thank you and I was trying to be careful and took ages replying and lots of replies.

    I must go as been here too long
