Black-headed Gull - White J9J2
Lowell's second winter sighting of a ringed Black-headed Gull was a couple of weeks after the BTO-ringed bird in Portrush, when he recorded a colour-ringed bird
near Dunne's in Coleraine.
The bird had been ringed as an adult in Ostensjovannet, Oslo only 169 days before on 9 April 2012. The movement of this bird was approximately 1168km.
Blue - Coleraine, Northern Ireland
Yellow - Oslo, Norway
