Talks By Roy Dennis on Monday 7th May and Monday 28th May. Questions to Ask?

  • To 'Ospreyfreak' Please do not deposit this sort of rubbish on an otherwise good-mannered site.

  • One hard and fast rule of mine is that  C2H5OH and the internet do not mix.

  • Very interesting,Tiger.

    I had read previously, can't actually remember where, it might have been on the link you have posted now, that there were reports of Osprey sighted on migration in Scotland pre the 1950s. If on migration, where to? Scandinavia?

    Re nesting sites, does the provision of man made structures interfere with the bird's ability to seek out and build nests over a wider area?

    I know of a nest site from 17yrs ago, which I think was a man made structure, now blown down, defunct and surrounded by forestry operations.

  • ClaireM  You might like to listen to The Bird Boys                Roy is a contributer.

    Also the attempted translocation by C W R Knight in 1929

     

     

  • Anyone attend the talk? It would be great to get a report.

  • Thank you mods for removing the abusive/offensive post.

  • Robert the Bruce

    I would like an update from Blue XD/Green J's nest

    Me too !!!!!!!!!

    And everyone seems to be asking the questions I'd like answered , like:

    from AG

    On a wider point, I'd like to know Roy's view on whether the weather over the last    several    weeks is likely to have the same impact on hatchings this year as the  storms had last year.  

    from JSB

    What evidence has Roy seen of parent osprey, trying to teach fledglings to fish, prior to their first migration?"

  • Another question to RD please.

    Do you think that by flying to a high altitude, an osprey may relatively easily find a known destination, even although the 'angle of approach' may be from different co-ordinates, from previous experiences? Effectively, as we would use a map, by turning it round to suit our route planning. I am thinking about Rothiemurchus' 2012 landfall in Devon, at his favourite spot, more or less, reached from a more easterly starting point on land, as opposed to the previous sea route.

  • Does anyone really need to turn a map round to navigate?

  • OG: Ahem!..........

    Orienteering........

    "Orienting the Map. It’s nice to have the map oriented the same way the earth is. You can do that by putting the compass on the map, and then turning both, until the compass needle points in the same way that “north” does on the map.

    Try to always hold the map so that’s oriented to the earth around you. Also, try to keep track of where you are on the map (e.g., by keeping your thumb there)—it’s amazing how much time you can lose if you have to keep stopping and looking that up again".

    Also a vehicle sat nav displays the route in the same manner.

  • Tiger: forgot to thank you for the link to The Bird Boys, a very interesting radio programme, well presented too.

    [BTW if it ever disappears from the BBC online archive, I have managed to download a copy to my computer for reference - but of course I never said that ;-)  ]

    The subject of osprey navigation sounds like an interesting one to raise. I'd like to know if there's been any research done into how the birds find their way to and from their wintering grounds, and particularly how the young know where to go.

  • RtB  I am glad you enjoyed the Bird Boys. I think it is a great programme and a great insight into the goings on at Loch Garten in the late fifties.

  • I suppose one must question for this talk is about Baldrick?

    Was this bird Baldrick?

    What was the confusion about the rings?

     

  • Yes that is a Q I was thinking of Tiger.

  • Hi, I wonder if anybody who is going to Roy's talk on 28th might feel like asking the following:

    1. Do Ospreys stash fish - not necessarily in the nest but perhaps in adjacent trees?

    2. Why do they not pick up fish when they drop them (or do they?), given they may drop down to ground level to pick up moss/divots for nesting?  We read about only 1 in 4 dives on average being successful so it seems a lot of effort to have to go and catch another.

    Grateful thanks in advance
