This is the second smallest European bird at 9 to 10 cm. The Firecrest is greenish above and has whitish underparts. It has two white wingbars, a black eye stripe and a white supercilium. It has a crest, orange in the male and yellow in the female, which is displayed during breeding, and gives rise to the English name for the species. This is a restless species, constantly on the move as it searches for insects, and frequently hovering. It resembles the Goldcrest, but its bronze shoulders and strong face pattern are distinctive.
