The Common Linnet (Linaria cannabina) is a small passerine bird of the finch family, Fringillidae. It derives its common name and the scientific name, Linaria, from its fondness for hemp seeds and flax seeds—flax being the English name of the plant from which linen is made.
The common linnet is a slim bird with a long tail. The upper parts are brown, the throat is sullied white and the bill is grey. The summer male has a grey nape, red head-patch and red breast. Females and young birds lack the red and have white underparts, the breast streaked buff.
