Nest 1 and Nest 2 intruder Blue BV: background details

Blue BV, who had intruded in August 2014 on Nest 1, paid several visits to that nest and one to Nest 2 in 2015. Here he is on Nest 1, with another intruder, Blue 69 in the background.

Ian Francis of the Grampian Ringing Group has told us that Blue BV was one of a brood of two from a long established nest in Donside, Aberdeenshire. He hatched in 2011, so was three years old when first seen at Kielder last year.

The first time he was identified in 2015 was on 30 July when he landed on Nest 2 and started eating a fish that juvenile Blue VM had been tucking into.

After standing beside Blue BV in the hope of being fed VM gave up and flew off. Sibling Blue VS arrived a few minutes later and took the fish off Blue BV.

Two days later Blue BV landed on Nest 1.

He ws soon joined by Blue 69 and then a little later Blue 2H, the 2012 Nest 2 offspring, also landed. Three males on YA’s nest but no sign of him!

Blue BV was seen again on Nest 1 later in the month. He seems to like the area – and the trout – so perhaps we’ll see him again next year.

Our thanks to Ian for sharing the details about him.

Ten ringed intruders were identified from the nestcams at Kielder in 2015 and there were at least a couple of unringed Ospreys in the area.

    Brilliant blog Joanna, and well done to you and the Kielder Team for taking the time and trouble to identify ten ringed intruders.

      Thanks, Mary. We very much enjoy being able to let ringers know that their Ospreys have made it back to the UK again, whether for the first time or after many successful migrations.

        I think it is very exciting to identify any returning birds Joanna, knowing which area they came from is interesting, as you well know sometimes they always don’t follow the rule book :-)

    We’re very happy that the wandering Glaslyn boys chose Kielder, Mary !

      So is everyone else Joanna lol – what a surprise that was to find them both at Kielder, everyone thought they were gone. :-)

    Thanks joanna, great blog. I have mixed feelings about intruders however I do like to read that an osprey has been identified and a bit about it’s background. Ten ringed intruders identified is amazing!
