Abstract
Gray-hooded Gull, Chroicocephalus cirrocephalus (Vieillot, 1818), is distributed across South America and considered a resident, with individuals in their non-breeding period able to disperse over long distances. We report the first records of this species from the state of Espírito Santo, the only state on the Brazilian coast without previous records. We suggest that the geographical distribution of this species is expanding along the Brazilian coast, in accordance with what has been previously suggested for Gray-hooded Gull.
