Herring Gull at Carrasqueira ricefields

Last Sunday, 23/11/2013 there was a 4cy Herring Gull most probably ssp. argenteus at Carrasqueira peninsula ricefields in the Sado Estuary. In the last 2 years Herring gull records increased in Portugal, much because of a great awarenness from the observers in general, however the majority of them are made in beaches and harbours along the coast, this one was my first record inland on a ricefield roost of Lesser black-backed Gulls.
