The species
The goldcrest (Regulus regulus) is a very small passerine bird in the kinglet family. Its colourful golden crest feathers gives rise to its English and scientific names, and possibly to it being called the "king of the birds" in European folklore. Several subspecies are recognised across the very large distribution range that includes much of Eurasia and the islands of Macaronesia. Birds from the north and east of its breeding range migrate to winter further south.
