Today I also saw both Polish colour-ringed Black-headed Gulls that winter in the islands - White TARM was at Grand Havre, while White TETT was on L'Ancresse Common. Both gulls were ringed at the same site in Poland- Przykona Reservoir, Radyczyny, Turek by Tomasz Iciek. TARM was ringed as an adult in June 2010, while TETT was ringed as a chick the following June.
