Osprey Q & A

This thread is a total experiment! I thought of it because a few nights ago, a lot of of useful information about ospreys was being posted in the LG Diary comments, but because of the blog format, it will be out of sight once a new blog is posted, and easily forgotten.       

The idea for this thread:

·         To provide a place for people to ask questions about ospreys at Loch Garten, or ospreys in general, which members of the Forum will answer to the best of their ability. NB Questions directed to the team at Loch Garten, should still be posted in the Comments area of the Loch Garten Osprey Diary.

·         To preserve the answers for future reference

Asking Questions

    Would that be the Lady of the Loch?

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

  • BTW, Tiger, I also agree that this thread needed promotion - thanks for bringing this one up, it's been interesting reading!

  • I know I wasnt putting it correctly Tiger, I didnt mean about them being partners, I was meaning was it possible that some not all may winter in the same vicinity or come upon each other in their wintering grounds as they must when they are in Scotland, as we discussed before when Blue XE didnt return Red 8T was supposed to have taken over his nest - so was just wondering if it was possible that their paths could cross in wintering grounds, OK guess it was a stupid question!  will keep my crazy fantasies to myself now LOL.....

    Edit: Also just wanted to bump the thread back up to the top again as I had to go looking for it way down on the next page.

    Alan was referring to a Canadian bird.

    Lady has had 22 breeding seasons if I have counted right.

  • Red Z pops up again, were discussing her not that long ago, she was a favourite of Roy's wasnt she.

  • MARY - I would not say this is a fantasy - As TIGER points out Ospreys chose there wintering grounds before there partners. But if Ospreys are in a close proximity at winter why should they not bump into each other.

    It would be very interesting should a partner or same year sibbling bump into each other what the reaction would be.

    Percentage wise very few tracked so we do not know and not many partners or sibblings tracked in the past.

    On 22 October 2009 LG bird Mallachie almost bumped into Rothes near Varela in Guinea Bissau.

  • Thanks very much Keith, thats the kind of info I was looking for, apart from the tracked birds we are not to know what goes on and where LOL....    I would love to know where EJ winters, presumably in Africa, but more interestingly Id love to know if any of Beatrice's or Green J's opffspring winter in Spain, wasnt some of Green J's juv's tracked sometime will have to do a search and see if I can find anything on it.

    She managed 18 years if you include the non-breeding season - thank goodness they cut off the baler twine in 1982, that could have been terrible.

  • This is fascinating reading. I have always presumed the apparent lack of 'social bond' between ospreys is due to the rules of survival. I still feel sure that one of EJ's earlier (unringed) offspring landed on the nest this year. Normally she would see an intruder off well before it had the chance to land - but on this occasion she didn't even get up, just sat and shouted for a bit. The bird returned again a few times and seemed to hang around the nest area that day. It seemed a case of "go off and find your own nest, I can't afford to feed you anymore". I haven't much experience and am probably wrong, but it's nice to speculate :-)

    I was also wondering, given the amazing distance Alba travelled to Africa in just a fortnight - and now Ceulan seems to be doing the same - does the age of migration make a difference? The older the chick, the stronger and more intuitive?

  • Mims   We do have a cast iron example of what happens when a young osprey returns to his home nest.

    Prior to John's sighting in the North Arm,             the bird had intruded briefly at the breeding nest before             being chased away by the male, 03(97): not a particularly             warm home-coming from his father if it was 5R!
