What is this map?
This map shows the change in breeding status between two atlases. Orange dots indicate losses - probable or confirmed breeding in the earlier atlas and not in the later atlas. Green dots indicate gains - probable or confirmed breeding in the later atlas but not in the earlier atlas. Grey dots indicate probable or confirmed breeding in both periods.
