The common linnet, Linaria cannabina, is a small, slender finch with a fondness for seeds, particularly those of hemp and flax. The male, in his breeding plumage, is distinguished by a grey nape, a striking red head-patch, and a red breast, while the female and juveniles are more subdued in coloration with white underparts and buff-streaked breasts.
When identifying the common linnet, look for the long tail and the contrast between the brown upper parts and the sullied white throat. The bill is grey, and the male's red accents are most vibrant during the breeding season.
This species prefers open land with dense shrubbery for breeding, including heathlands and gardens.
The common linnet has a wide range across Europe, the western Palearctic, and North Africa. It is partially migratory, with many birds from the east and north moving southward or toward coastal areas during the non-breeding season.
Outside of breeding season, common linnets may gather in large flocks, occasionally mixing with other finch species. They are known for their delightful song, which features rapid trills and twitters. Breeding involves nest building within bushes and laying clutches of four to seven eggs.
The song of the common linnet is characterized by its pleasant and melodious trills and twitters, often heard during the breeding season.
The common linnet's diet consists mainly of seeds, including those from arable weeds, crucifers, chickweeds, dandelions, thistles, and trees such as hawthorn and birch. They also consume a small amount of invertebrates, particularly when feeding chicks.
The common linnet is listed as a species of Least Concern by the IUCN. However, in the UK, it is recognized as a priority species for conservation due to significant population declines, largely attributed to changes in agricultural practices. Conservation efforts include promoting bird-friendly farming practices and habitat management.
