Barn Owl – 1980s winter

Tyto alba – TYLLUAN WEN – Breeding resident.

The Winter Atlas showed that Barn Owls were recorded in 14 out of 27 of the county’s 10km squares during the winters of 1981-82, 1982-82 and 1983-84.

The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents over 3 birds recorded in a day.

This species can be difficult to detect in the winter when it is mainly nocturnal and silent, which despite being a resident, has resulted in a 40% lower registration than in the 1970 breeding atlas survey.
