In the breeding season gadwall favour lowland, shallow, eutrophic waters. They were suspected of attempted breeding at Marloes Mere from 1996 but it was not proven. Breeding was confirmed at Skomer in 2000, 2001 and 2004, the latter during the 2003-07 survey, when they also probably bred at Bosherston, though no ducklings were seen.
