The
common firecrest (
Regulus ignicapilla) also known as the
firecrest, is a very small
passerine bird in the
kinglet family. It breeds in most of
temperate Europe and northwestern Africa, and is partially
migratory, with birds from central Europe wintering to the south and west of their breeding range. Firecrests in the
Balearic Islands and north Africa are widely recognised as a separate
subspecies, but the population on
Madeira, previously also treated as a subspecies, is now treated as a distinct species, the
Madeira firecrest,
Regulus madeirensis. A fossil ancestor of the firecrest has been identified from a single wing bone.
This kinglet is greenish above and has whitish underparts. It has two white wingbars, a black eye stripe and a white
supercilium. The head crest, orange in the male and yellow in the female, is
displayed during breeding, and gives rise to the English and scientific names for the species. This bird superficially resembles the
goldcrest, which largely shares its European range, but the firecrest's bronze shoulders and strong face pattern are distinctive. The
song is a repetition of high thin notes, slightly lower-pitched than those of its relative.
The common firecrest breeds in
broadleaved or
coniferous woodland and gardens, building its compact, three-layered nest on a tree branch. Seven to twelve eggs are incubated by the female alone. Both parents feed the chicks, which
fledge 22–24 days after hatching. This kinglet is constantly on the move and frequently hovers as it searches for insects to eat, and in winter it is often found with flocks of
tits. Despite some possible local declines, the species is not the subject of significant conservation concerns owing to its large European population and an expansion of its range over the last century. It may be hunted and killed by
birds of prey, and can carry parasites. It is possible that this species was the original "king of the birds" in European folklore.
