The Osprey Chat Thread For May, June 2012

  • Starting a new osprey chat thread for May 2012. This thread is for chat about ospreys only.

    On the first of April I was asked what I might be writing on May 1st?

    Well there have certainly been some suprises. Odin did turn up later on 1st April but we could not observe him as the cam was down.

    EJ allegedly attacked blue XD and returned to domestic bliss with Odin. Well not quite as for the first few days EJ was going absent and apparently she was seen visiting old flame blue XD. Then his wife came back and EJ returned to domestic bliss with Odin.

    The first egg arrived on Monday  April 9th and  Odin was very suspicious of it. For a while it looked as if he might kick it out of the nest.

    He didn't and then accepted two more eggs as his.

    The other main feature of the month was the severe weather. There was heavy snow, persistent heavy rain and on two occasions EJ seemed as of she was in the deep freeze  so bad was the frost on her.

    One hopes that the eggs have survived.

     

     

     

  • Thank you for the rayzoomay, TIGER - it seems like a lot of water under the bridge since those eventful days.  Now all is quiet, we're anxious that the eggs have survived the harsh conditions, in a couple of weeks we should know something.

  • Not sure if this video has been shown before.

    It is a Gerry Ridsdale video of ospreys in HD

    See   videos

    Three osprey videos and a golden eagle one.

  • just think TIGER all that happened in the first chapter

    Well life will have certainly moved on by the time the next thread is due on June 1st

    Hopefully there will be three chicks growing rapidly Odin working all hours to feed them.

  • So hope that will be the case

  • sorry TIGER  what i meant was the first month---ie: april

  • Looking at Tweed Valley reminded me of another topic and I thought it might need a thread on its own but then I thought that here is as good a place as any.

    Question is why does the male osprey always eat the head of the fish?

     

    Is it because it is nutritious?

    It it because it ensures the fish is dead?

    Or some other reason?

    Looking at Tweed Valley reminded me of another topic and I thought it might need a thread on its own but then I thought that here is as good a place as any.

    Question is why does the male osprey always eat the head of the fish?

     Is it because it is nutritious?

    It it because it ensures the fish is dead?

    Or some other reason?

    I've pondered this one as well Tiger but haven't come to any conclusions.

    A few occasions when whole fish have been delivered to nests have shown that flapping fish could present a potential danger to eggs/chicks, but I'm not aware of any actual harm that has arisen anywhere.

    When I worked a lot in SE Asia, my local colleagues all regarded the fish head (particularly the cheeks) as a real delicacy. One colleague liked eating at restaurants where the diner selected the (live) fish from tanks which were then cooked to order, because his kids always got the fish cheeks at home, but there was no competition for them from the westerners. Not sure if this is the same for eating them raw.

    Its going to be easier to start eating a fsh from the head end rather than the tail as there are more places to get a grip of with a beak, and there may be some nutritional differences.

    I can't see how one would research this scientifically, but I'm sure someone has tried somewhere.

  • In one of the recent RW(?) blogs (last couple of days) it says that the brain is extrememly nutricious so perhaps its better nourishment for the male who has to be doing all the fishing at this time

  • Here is a superlink to all the osprey related topics including photographers.

     

  • Has anyone ever seen an adult osprey, male or female, NOT eat a fish from the head down?

    Yes agree that the head has to be the easiest place to start from. Less chance also of the fish escaping when it is grasped head upwards, against the lie of the scales and behind the gills. We know ospreys have barbed pads on the soles of their feet but holding the fish in such a way would give an even better purchase.

    Another advantage of eating the head first might be that the fish is killed more quickly which must make it less of an effort to eat. Not that it seems to bother the osprey too much either way.

    When there are chicks to be fed, and once the head is eaten away plus a portion of body, it not only ensures a dead fish on the nest when the chicks are small but provides easy access for the female to quickly tear off small, soft pieces of flesh to feed to the youngsters.

    Even before there are eggs/chicks on the nest the male will still eat his share of the fish, head first, before giving the remains to the female. Sometimes he gives her very little at this point but then she is not expending as much energy as he is. Is it because he needs to build himself up in order to meet the increasing demands of an ever growing family or is he merely exercising pecking order rights as chief provider?

  • I do not know what the attraction of fish heads is anyway. I have never eaten one in my life!
