Résumé :	This report summarises the non-passerine scarce migrant birds recorded in Britain in 2018. For many species, 2018 was an average year, with annual totals slightly above the long-term mean. One exception was White-billed Diver Gavia adamsii, for which it was the best year to date (72 individuals, up from 38 in 2017), although almost half the annual total (32) came from a boat-based survey off Portsoy (North-east Scotland) on 16th April. Other species that put in strong showings were Surf Scoter Melanitta perspicillata (24 individuals/2nd best year on record), Ring-necked Duck Aythya collaris (29/5th), Glossy Ibis Plegadis falcinellus (56/6th), Black-winged Stilt Himantopus himantopus (27/6th) and Wilson's Storm-petrel Oceanites oceanicus (62/6th). Species faring less well in 2018 included Lesser Scaup Aythya affinis and Kentish Plover Charadrius alexandrinus, with just five and six records respectively; both species are scheduled to return to national rarity status from 2020. Eight White-rumped Sandpipers Calidris fuscicollis was the lowest total since 1997, while numbers of Temminck's Stints C. temminckii were also below average for the third consecutive year. Ten Red-footed Falcons Falco verpertinus was a poor showing after 42 in 2017, while it was another unexceptional year for Wrynecks.
