Busard cendré
Montagu's harrier is a rare breeding bird in Britain. There are two breeding areas – the area surrounding The Wash, and downland areas of southern England, from Dorset and Hampshire north to Oxfordshire. Away from these areas it occurs only as a scarce migrant. One site, Estuary Farm, near North Wootton in west Norfolk, a special observation area was negotiated with local landowners, so that pressure could be taken off other nesting pairs. In 2005, a pair bred on the Holkham estate. In 2015, it was reported that some Montagu's harrier were nesting at Blacktoft Sands, East Riding of Yorkshire.
