Fig. 2. Range change in Black-winged Stilts Himantopus himantopus between the two European Breeding Bird Atlases, mid 1980s and 2013–17. Orange squares show range loss, blue squares range gain, grey squares are those with records in both atlas periods. Paler squares are those with poorer coverage in the first atlas so assessments of range change there may be unreliable. The maps show records regardless of breeding evidence, so for example the apparent range loss in Yorkshire since the first atlas refers to the presence of a non-breeding bird in the first atlas period.
