Returning Norwegian ringed Black-headed Gull at Llanddulas.
There is a darvic ringed Black-headed Gull at Llanddulas
which I first saw in the Feb 2013. It was ringed in Oslo in 2008. After a year’s
gap I re-sighted the bird in exactly the same carpark and was able to get more
recent details on the birds movements. Since it was darviced it has returned every
year to breed near Oslo and seems to use Llanddulas as a regular wintering site,
approximately 700 miles away. I wonder how many more of our BH Gulls are from
the same area?
