Skriker

Overview
The Skriker (or Shrieker) of Lancashire and Yorkshire is a death omen like many others of its type, but it also wanders invisibly in the woods at night uttering loud, piercing shrieks. It may also take visible form as a large black dog with enormous paws that make a splashing sound when walking, like "old shoes walking in soft mud". For this reason the Skriker is also known as Trash, another word for trudge or slog. The name Skriker is also derived from a dialect word for screech in reference to its frightful utterances.
