Madeira firecrest
Regulus madeirensis
The Madeira firecrest, Madeira kinglet, or Madeiracrest is a very small passerine bird endemic to the island of Madeira. It is a member of the kinglet family. Before it was recognised as a separate species in 2003, it was classified as a subspecies of the common firecrest. It differs in appearance and vocalisations from its relative, and genetic analysis has confirmed it as a different species.
