The young Bohemian waxwing has a short, soft yellow bill and grey, fluffy plumage without bright blue markings. After a period of rapid growth, the young species develops blue spots on its wings and black stripes on its head. An adult Eurasian jay possesses a strong black bill suited for cracking nuts and catching insects. The adult’s body is pinkish-brown, with a white head featuring black stripes, and bright blue spots with black and white stripes on its wings; the tail is black. Wide wings enable the species to fly quickly between trees.
