    Interesting news, but not necessarily a good idea if you want to maintain a healthy breeding stock. Darwinian natural selection, it is not.

    Healthy breeding stock?!? With 144 birds left, I think we're way past that.

    Ach, the species is nearly extinct. It shows how important each and every one of them is when such lengths are gone to to save one. In addition, every defect as with humans, is not hereditary.

    "2018 Breeding Season Outline
    Golden Eagle Trust

    Golden Eagle
    The Golden Eagles had another good year in 2018 and three young fledged in the wild. One coastal pair reared two young and the pair in the Bluestack Mountains reared a single chick again. No pairs laid eggs in the Derryveagh Mountains in 2018. This follows on from 3 young fledged in 2017 also. 18 young have fledged in County Donegal since the first successful breeding in 2007.

    5 territories were occupied including, South Derryveagh, North Derryveagh/Glenveagh National Park (where the 17-year old female disappeared in 2017, presumably from natural mortality or old age), Inishowen Peninsula, Bluestack Mountains and the Glencolumbkille Peninsula/Slieve Toohey.

    3 Scottish Golden Eagles were translocated and released in Southern Scotland in 2018. This release programme aims to release 6-10 birds in Southern Scotland over the coming years and we should expect the occasional released bird to disperse across to Northern Ireland and Donegal.

    White-tailed Sea Eagle
    Unfortunately, at the start of the breeding season; our two most productive breeding pairs (on Lough Derg, Mountshannon and Portumna) suffered the loss of their respective females during February and March. The Mountshannon female was confirmed to have died from Avian Influenza and the missing Portumna female is presumed to have died from Avian flu also.

    However, of the 12 territorial pairs at the start of the breeding season; 10 pairs laid eggs. 6 pairs hatched young and 4 of these pairs fledged one chick each (4 chicks fledged in total). Of the 4 pairs that failed at egg stage, two breeding sites involved “Trios”, which seems to have been part of the reason why the clutches failed.
    Of the 12 pairs at the start of the season, 7 were in County Kerry, two were in County Cork (Garnish Island and Glengarriff), two in Galway and one in Clare. 3 of the single chicks fledged in Kerry and a single chick fledged in Connemara (SW od Oughterard). 23 White-tailed Eagles have fledged in the wild in Ireland, since 2013.

    A nest camera was fitted near to the nest on Garnish Island, in the pre-breeding season, by NPWS and OPW, but unfortunately this breeding attempt involved three adults and failed.

    Red Kite
    The Wicklow kite population continues to expand year on year. It is easy to forget that the early part of the 2018 breeding season was quite cold and wet and a number of established kite pairs failed early. However, it is clear that there were over 80 pairs of territorial kites in Wicklow this year, which were monitored by a combination of voluntary and some paid fieldwork.

    At least 63 young Red Kites fledged in County Wicklow this year and we expect many others fledged elsewhere in the county also. In Dublin, there were 5 territorial pairs in a pocket of rich farmland near Ashbourne. 4 Dublin chicks were ringed and a 5th newly fledged juvenile kite was seen near Ashbourne Golf course (from an unlocated nest).

    So, in total, we believe that there were over 85 pairs of kites in Wicklow and Dublin in 2018 and there was an absolute minimum of 68 young kites fledged on the east coast in 2018.

    IRISH BREEDING TOTALS 2018

    Golden Eagle
    5 Territorial Pairs 3 young fledged

    White-tailed Sea Eagle
    12 Territorial Pairs 4 young fledged

    Red Kite
    85+ Territorial Pairs 68+ young fledged"

    Not a bad year especially considering the deaths of the WTE due to avian flu.

    Good photo alright. Would be interesting to find out whether the lamb was alive or dead when it was taken, but I guess we'll never know.

    I reckon it's arbarent behaviour tbh. That said it does show the size of prey these birds can manage.

    I reckon there will always be hyperbole in reaction to such incidents. But the usual will no one think of the children! is the classic;)

    Its highly likely the lamb was simply picked up as carrion as Sea-Eagles are primarily scavengers. Studies in Scotland highlight this

    Yes but they do take live prey. My sister goes to Mull a couple of times a year and last time she was talking to one of the locals about the sea eagles and he said that he saw one take a fully grown goose.

    Not disputing that - I was talking in terms of lambs/sheep. The Sea-Eagles on Lough Derg snack on the likes of Ducks and Coots during the winter when fish are scarcer. Also coastal pairs will take various kinds of Sea-Birds. Indeed in other parts of Europe fishermen like them as they often prey on young Cormorants

    Yes, even if a few live lambs are taken the eagles are popular on Mull. It is reckoned that the island gets an additional £5M pounds per year from tourism due to the eagles. Everyone on the island benefits from this, including the farmers

    Interestingly, the heatwave hasn't been as beneficial for other insects - last year was one of the worst years for bumblebees with a 17% drop in numbers.
    The National Diversity Data Centre began monitoring bumblebee numbers in 2012.
    "It was really quite dramatic," says Dr Murray of the drop in numbers last year.
    The bad snow storm in March last year combined with the summer drought "really did not benefit bumblebees".
    Bees are vital for biodiversity and on Thursday, Ireland became only the second country in the world to declare a climate and biodiversity emergency.
    The United Kingdom became the first country to declare the emergency earlier this month, on 1 May.
    Conversely, butterfly populations by comparison did really well during last year’s snow storm and long, dry summer. Their numbers went up by 29%, says Dr Murray.

    From a longer piece on how wasps benefitted from last year's heatwave and should be seen in greater numbers this year as a result. Not so good for Bumblebees however.

    ALLELUIA!!!! :) It's not much of a fine, cashwise, but it's a start.


  • Registered Users, Registered Users 2 Posts: 53 ✭✭The_Outsider


    Great news.
    As mentioned, not much of a fine, but a start.

    Only this morning though I passed a tractor buzzing the roadside hedge on a local stratch of road - taking a serious chunk off it.
    What vegetation was there certainly didn't merit another going over.
    All on a straight piece of road - so the defence of 'it's for road safety' doesn't stand here.

    How do Councils get away with this??
    It definitely wasn't a local farmer ; proper signage out, mega John Deere etc.

    Interesting that they have outlived their first hosts.

    Maybe Archaeopteryx or something like that.

    Archaeopteryx died out about 35 million years before the bugs first appeared.

    Perhaps it was pterosaurs then.

    More likely an early Cretaceous period tree dwelling mammal.

    Just seen a nest been disturbed by some landscapers. mentioned it to them but they are claiming they are allowed to cut the hedge as it is cultivated and in a commercial estate. Is this correct??

    my understanding is yes and no.
    yes, they are allowed cut hedges as they are cultivated.
    no, they are not allowed disturb wild birds' nests.

    was the nest destroyed?
