Yet another Satellite Tracked Golden Eagle goes off the radar

It is with great anger and disappointment that we are reporting, once again, the mysterious loss of another of Roy Dennis’s satellite tagged Golden Eagles. This time the eagle, a  two year old bird called Angus 33  disappeared on the 13th May on the Glenbuchat Estate. Although the location from where the last signal had been received was extensively searched by Police, not surprisingly nothing was found of the missing eagle. According to the Raptor Track web site, it is thought most likely the loss of the eagle was the result of human interference. To keep up with events relating to this incident click here. This makes the number of tagged eagles which have vanished to five – four Golden and a single White-tailed eagle. We just wonder how many untagged eagles of both species are now being lost without anyone being any the wiser?


Destroyed Golden Eagle nest found in early June by Terry Pickford in Scotland. Both eggs had been thrown from the nest and were found scattered on the floor below the eyrie.

    why tag any bird? if they are going to be destroyed illegally, as hundreds are. the tag is useless, it will be destroyed as soon as the bird is killed!these people are switched on now, they no longer kill them in the “good old ways” they are much more carefull and know what to look for on a dead raptor. i really question as i have done before, the benefits of ringing, weighing, tagging and generally messing about with these birds in the 1st place. i believe the benefits do not out weigh the problems. In most cases. So what benefit did tagging thes birds have? that they just dissapeared? that they moved from here to there before they dissapeared? we have a huge amount of data on these birds allready and i personally believe that there is no justification for the disturbance required to ring these birds or otherwise interfere with them at the nest, the information gathered is so slight that its not worth the disturbance to them, i recon there are a few failures due directly to “conservationists efforts” leave everything alone i recon, protect from afar let them get on with it without messing about with them unnecesarily?

    • Ringing, tagging, tracking, monitoring, as well as bird protection laws, have and always will fail to protect our iconic raptors so long as the multi million pound business of shooting is allowed to thrive. Conservation will always come a very poor second to activities that generate wealth for the landed gentry.

      I couldnt dissagree more Keith. As far as i can see, there is no current evidence to indicate that the disturbace of being fitted with a transmitter causes any long term damage.
      What it does do is demonstrate where the issues are.
      The birds go missing in the same areas all the time.
      Then you can identify the killing estates. I think a lot of estates are not so poison or trigger happy now because there is always the danger of there being a tag and another statistic attached to the estate.
      Tagging red kites is a brilliant way to highlight any poisoning estate.
      The most important factor to me, is that by monitoring the number of tagged birds, that stop transmitting in supsicious ways, we can determine a reasonably accurate figure for all wild/non tagged raptors being killed.
      Over a reasonable period, it could even be used as justification, to force the estates to contibute to additional rearing of raptors to replace the ones killed.
      Currently radio tags is the only effective tool we have to monitor what is actually happening.




    tagging birds is a good idea but will they get reported if they collide with the ever increasing wind turbines, wind turbines are predicted to kill 10 per cent of the white-tailed sea eagle population over a 10-year period. there are currently 30 breeding pairs of eagles on the Isle of Skye and new turbines are expected to cause a mortality rate of about six birds each year. farmers are having trouble with some eagles taking their lambs I have photographic evidence of a golden eagle carrying off a lamb, Red kites conservation groups in Berkshire are claiming the proliferation of red kites in urban areas around reading could endanger pet animals. Red kites were reintroduced to the Chilterns in 1989 and their numbers are believed to be up to 600 breeding pairs, from an initial introduction of 93 birds. they are upsetting the balance of nature in the Chilterns;

  • It would help if the radio tags/geolocators were internal. Then we’d be able to find where they were buried!
    As for Carole above anyone leaving their pet dead rabbits out in the garden should be worried about kites other live pets should be safe enough…apart from pet worms and beetles that is

    Raptor Persecution Scotland shared a link.

    27 eagles, 7 years, 0 prosecutions
    Last September we wrote an article called ’26 eagles, 6 years, 0 prosecutions’ (see here). We thought it was time to update it and it’s now called: ’27 eagles, 7 years, 0 prosecutions’. Why update …

  • Very nice style and design and great subject material , very little else we need : D.
