Map explanation
This map shows where changes occurred in the relative abundance 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.

The natural world range of Little Owls extends across Eurasia from Iberia to China's Yellow Sea and southwards from the Baltic to Mediterranean Africa with outlying populations elsewhere in Africa north of the equator. Fossil evidence shows that they existed in Great Britain in pre-historic times but by the modern era the species had died out here until it was re-introduced in the late 19th century. Much of southern lowland England provided the type of habitat in which they could thrive and by the 1950s they had spread throughout England and Wales and were beginning to appear in Scotland.
In Wiltshire there were a few scattered records in the 19th century, assumed to be of escapes or failed introductions, but it wasn't until the first decades of the 20th century that they began to appear regularly. By 1920 they were reported to be established over the whole county, reaching a peak in the 1930s. Thereafter there was some overall decline nationally thought to have been caused by harsh winters in the 1940s and increased use of pesticides, before numbers stabilised in the 1970s. Numbers in Wiltshire remained stable from 1974 until the end of the century. Birds of Wiltshire recorded them present in 290 tetrads (32%), with breeding in 140 of them. Since then however there has been a sharp decline; WTA2 recorded their presence in only 152 tetrads with breeding in 72. This is consistent with the national trend recorded in Bird Atlas 2007-2011 which showed a decline in abundance in the south-western side of Britain, partly offset by increases in north-east and eastern England, possibly caused by changes in farming practices leading to decreased food supply.
