Résumé :	This report presents data on the non-passerine scarce migrants recorded in Britain during 2011-12. To a large extent, the patterns illustrated here continue some long-term trends, with good numbers of most herons and their allies and Nearctic waders, while other species - Ferruginous Duck Aythya nyroca, Night Heron Nycticorax nycticorax, Kentish Plover Charadrius alexandrinus, White-winged Black Tern Chlidonias leucopterus and Red-footed Falcon Falco vespertinus were genuinely rare. The year 2011 was a record one for no fewer than six species - Great White Egret Ardea alba, Purple Heron A. purpurea, Black Kite Milvus migrans, American Golden Plover Pluvialis dominica, Buff-breasted Calidris subruficollis and Pectoral Sandpipers C. melanotos - although the record total of American Golden Plovers lasted only one year before being eclipsed in 2012.
