Northern Scottish Gaelic has a lot of non-Ulster features in popular with Munster Irish. Though southern Donegal Irish tends to use ní a lot more than cha(n), cha(n) has virtually ousted ní in northernmost dialects (e.g. Rosguill and Tory Island), however even in these spots níl "is not" is a lot more widespread than chan fhuil or cha bhfuil.
