Thrush Nightingales are unpretentious in appearance, with their uniform brown plumage. Their only more colourful feature is their reddish brown tail. Their breasts have mottled greyish brown markings. They can be distinguished from otherwise similar female Redstarts by their larger size and generally darker appearance. Their longer legs also differentiate them from warblers. Thrush Nightingales’ legs are pale brown, their beaks are dark brown, and they have reddish brown eyes.
