Conservation status: Amber
Willow warblers are small birds with grey-green backs and pale under parts. They have a yellow tinged chest and throat and pale supercillium (the stripe above the eye). They are separated from the very similar chiffchaff by their song. Their population, especially in southern Britain, has undergone a moderate decline over the past 25 years making them an Amber List species.
