Pembrokeshire Avifauna committee in 1980s BTO winter atlas, GHR, Long-eared Owl

 

The BTO winter atlas showed the 10km squares where Long-eared Owls were recorded 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 2 birds seen in a day, the lighter blue represents single birds.
