I rarely leave without something interesting happening, and today was no exception. Modern technology means that if you know the correct channels, in some cases, it's possible to get information on your ringed gulls immediately. That is, if they're Norwegian courtesy of Ringmerking...
|first-winter Great Black-backed Gull - black ringed J5493|
2nd-winter Caspian Gull XCDD - ringed in Lausitz, Germany (close to the Polish border) in a mixed colony where Caspian Gulls dominate.
1st-winter Caspian Gull - green-ringed though too distant for combination to be read easily. Either a German or a Polish bird.
