The Goldcrest is a very small bird with golden crest feathers,
hence the name. It is called the ‘king of birds’ in European
folk law and is resident in Europe, including the UK, all year
round. Willow Warblers are small birds with grey-green backs and pale underparts. Their chest and throat is tinged yellow and they have a stripe above the eye. Unfortunately the Willow Warblers population has declined in Britain over the past 25 years, making them an amber list species.
