Taxonomy
The corn bunting was
formally described by the Swedish naturalist
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the ...

Description
In Turkey
This is an unusual bunting because the plumages of the sexes are similar in appearance, though the male is approximately 20% larger than the female. This large bulky bunting is 16–19 cm long, with a conspicuously dark eye and yellowish mandibles. Males lack any showy colours, especially on the head, which is otherwise typical of genus ''Emberiza''. Both sexes look something like

s, being streaked grey-brown above with whitish underparts. The underparts are streaked over the flanks and breast, and the streaking forms gorget around the throat. The lesser wing coverts are distinctively dark and white-tipped. The tail is plain brown.
The song of the male is a repetitive metallic sound, usually likened to jangling keys, which is given from a low bush, fence post or telephone wires.

The corn bunting is a bird of open country with trees, such as farmland and weedy wasteland. It has declined greatly in north-west Europe due to intensive agricultural practices depriving it of its food supply of weed seeds and insects, the latter especially vital when feeding the young. It has recently become extinct in

Behaviour and ecology
Food and feeding
Its natural food consists mainly of seeds but also includes insects such as crickets, especially when feeding young.
Breeding
Males defend territories in the breeding season and can be
polygynous
Polygyny (; from Neoclassical Greek πολυγυνία (); ) is the most common and accepted form of polygamy around the world, entailing the marriage of a man with several women.
Incidence

, with up to three females per breeding male. The population sex ratio is generally 1:1, which means some males remain unmated during a season. Males play only a small role in parental care; they are not involved in nest building or incubation, and only feed the chicks when they are over half grown.
The nest is made of grass, lined with hair or fine grass, and is usually built on the ground. Average clutch size is four, but commonly varies from three to five, occasionally six.
