| In previous Blog posts about the new Bird Atlas, Shane Wolsey has provided extracts and information about two species showing range expansion in NI - Great Spotted Woodpecker and Little Egret. Another which we are featuring is Blackcap. |

There has been a 77% increase in the number of 10km squares occupied in winter since the 1981-84 Winter Atlas throughout Britain and Ireland. However, the breeding distribution increase in Ireland since the 1968-72 Breeding Atlas has been an amazing 249%! The map below shows that Blackcap now breeds throughout Ireland with only very few 10km squares not showing a record:
