This strong migrant is a rare but regular vagrant to western Europe. In Britain, occasional small flocks occur, including five at Loch Leven, Scotland in September 2003 and four at Standlake in Oxfordshire in April 2015. In Ireland one or two individuals can be seen at any time of year. Vagrant individuals also occur each year in Central America as far south as Costa Rica between October/November and May/June. They have also been reported in small numbers in Suriname and French Guiana, in northern South America.
