This report publishes 365 new records of 93 rare taxa in Spain, with an acceptance rate of 88.81%. It is the first report that does not include a single record of any new species for Spain, so there are no additions to the Spanish list. It does, however, include the first accepted records of Goldeneye (Bucephala clangula) since the species officially became a rarity in January 2014 and the first record of Snow Goose (Anser caerulescens) assignable to Category A. Furthermore, previously accepted records of Great Knot (Calidris tenuirostris) and Cape/Australian Gannet (Morus capensis/serrator) were reviewed and consider not proven, thus removing them from the Spanish List. The most remarkable records are of a ‘Caspian’ Stonechat (Saxicola maurus hemprichii) (first for the Canary Islands and second for Spain), a Bobolink (Dolichonyx oryzivoru) (second for the Canary Islands and Spain), a Red-footed Booby (Sula sula) (second for the Canary Islands and third for Spain), Lesser Sand Plover (Charadrius mongolus) (second for the Canary Islands and third for Spain) and two Pied-billed Grebes (Podylimbus podiceps) (second and third for the Canary Islands). Also of note is a record of a Corncrake (Crex crex) exhibiting breeding behavior.
