Linnet, Acanthis cannabina. Resident, summer and winter visitor; general except northern Scotland. Gorse heaths, hedgerows and gardens, coastal dunes and links. In winter often in stubbles.
DESCRIPTION: 5 inches. Sexes differ somewhat. Male shown in spring; loses colour in winter but chestnut back distinguishes from streaky brown female and juvenile (and from 15 and 16).
VOICE: Repeated call note on wing, less metallic than 15 and 16, is best guide. Pretty rippling song recalls canary.
HABITS: Feeds mainly on ground where it hops. Often breeds in groups and large flocks form in autumn and for roosting.
MAY BE CONFUSED with 15, 16.
