The European robin belongs to the Muscicapidae family, the Old World flycatchers, though for many years it was grouped with the thrushes. It is a small passerine, measuring about 12.5–14 cm in length and weighing approximately 16–22 grams. Its most striking feature is the reddish-orange face and chest, bordered with grey, set against a brownish back and pale belly. Males and females are identical in appearance, a rarity among songbirds, and even juveniles—though initially brown and speckled—grow into that distinctive crimson bib.
