Map explanation
This map shows where changes occurred in the breeding season distribution of the species in Wiltshire between 1995-2000 and 2007-2012, as revealed by the fieldwork for Birds of Wiltshire (Wiltshire Ornithological Society 2007) and the shared fieldwork for Bird Atlas 2007-2011 (BTO 2013) and for Wiltshire Tetrad Atlas 2007-2012.

Great Crested Grebes favour relatively large areas of open, still water with emergent vegetation. Their breeding range covers much of temperate Eurasia, extending discontinuously through sub-Saharan Africa, Australia and New Zealand. In Britain, which lies at the western edge of their range, the species was driven almost to extinction in the 19th century through the combined activities of egg-collectors, river keepers (who saw it as a threat to fish stocks) and the fashion trade (which used its feathers for decorations), but has since recovered thanks to a succession of Bird Protection Acts. It is now safely established throughout much of lowland England, parts of Wales and lowland Scotland.
In Wiltshire, there were only occasional records of stragglers up until the end of the 19th century. They were first recorded breeding in 1912, at Coate Water, and numbers gradually increased thereafter: Birds of Wiltshire recorded them present in summer in 59 tetrads, with breeding confirmed or probable in 44. WTA2 showed little further change with breeding confirmed or probable in 47 tetrads out of 57 where the species was found to be present.
In winter the resident Wiltshire population is swollen, firstly by birds moving to the larger water bodies such as the lakes at the Cotswold Water Park to moult (which can temporarily swell the county population in autumn to over 300) and subsequently by winter migrants from continental Europe creating winter peaks of up to 250.
