Common firecrest

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,...
