Birks is a fell in the English Lake District situated two kilometres south west of the village of Patterdale in the Eastern Fells. The fells summit sits on a shoulder of the north east ridge of the higher and better known fell of St Sunday Crag, by which it is dominated, walkers often pass over the top of Birks either climbing or descending from the larger fell. The fell's name means a place where Birch trees predominate.
