This winter a Caspian gull (Larus cachinnans) has been reported several times on the Algarve coast. The first sighting was at a pelagic organised on 17 December by a group of Spanish birdwatchers, where two Caspian gulls were seen, one ringed in the Czechia, white ring with the code 948:U, and the other without a ring.
The ringed gull was then rediscovered on 28 December on Cancela Velha beach and after a month's absence it was discovered again on 30 January on Monte Gordo beach.
On 5 February Susana and I went to Monte Gordo to try and find the gull because it was a species we had both never seen before and once we reached the fishermen's area on the beach it was relatively easy to find.
Then at home I searched the European colour-ring Birding website for the contact details of the project responsible for ringing and reported the sighting. The next day I received an e-mail with all the information about it.
