Osprey Chat Thread for August 2018

  • Continued from Osprey Chat for July 2018

  • Thanks for the new thread, Tiger.

  • There  have been an interesting number of developments in observing ospreys in their winter quarters  in recent years. 

    A recent development in the Gambia is to have someone there permanently and he is now equipped by with 4x4

    Yesterday he did a survey found a small number of ospreys in place.

    No doubt they will get company very soon.

    The pictures are in closed Facebook Groups so I cannot copy them. 

  • Has anyone heard about Rothiemurchus? I had a whisper that he might be nesting this year. 

  • Maybe the same whisper I heard Tiger :-) 

  • Ooooo, Tiger and Mary, that would definitely be good news!

  • When do the juveniles lose the pale tips to their feathers? Is it after they moult for the first time? If so, when does that happen?

  • I think that it is when they moult, as you say Alison, and that would be after migration and during their time in Africa or wherever.

  • There is a short video clip on Aviemore Facebook this morning of an Osprey diving for fish

    and a still shot by the same guy.

    Thanks, Mike.

    When do the juveniles lose the pale tips to their feathers? Is it after they moult for the first time? If so, when does that happen?

    I should know the answer to this but I cannot be sure. 

    I think it is about 18 months.

    There are a number of people who now travel regularly to the Gambia to view juveniles in their winder quarters. One of them should be able to give a definite answer. 

  • If would be great to get definite  news of Rothiemurchus and wonderful news of the whisperings

  • Some great A9 osprey pictures

  • Thanks Tiger for the link. I have a lot of books on ospreys but I don't remember reading about them shutting their eyes before they hit the water. Perhaps between now and next March, I'll read Tim Mackrill's PhD. I doubt he covers that kind of behaviour as the thesis is about migratory behaviour, but I'm sure it'll be an interesting read. It's freely available via Roy's site but I've given the link anyway so folk can download it if interested.
