Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation. Agronomy has come to include research of plant genetics, plant physiology, meteorology, and soil science. It is the application of a combination of sciences such as biology, chemistry, economics, ecology, earth science, and genetics. Professionals of agronomy are termed agronomists.
The Eurasian magpie or common magpie is a resident breeding bird throughout the northern part of the Eurasian continent. It is one of several birds in the crow family (corvids) designated magpies, and belongs to the Holarctic radiation of "monochrome" magpies. In Europe, "magpie" is used by English speakers as a synonym for the Eurasian magpie: the only other magpie in Europe is the Iberian magpie, which is limited to the Iberian Peninsula. Despite having a shared name and similar colouration, it is not closely related to the Australian Magpie.
The buntings are a group of Old World passerine birds forming the genus Emberiza, the only genus in the family Emberizidae. The family contains 45 species. They are seed-eating birds with stubby, conical bills.
Bird migration is the regular seasonal movement, often north and south, along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funnelled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea.
The Eurasian woodcock is a medium-small wading bird found in temperate and subarctic Eurasia. It has cryptic camouflage to suit its woodland habitat, with reddish-brown upperparts and buff-coloured underparts. Its eyes are set far back on its head to give it 360-degree vision and it probes in the ground for food with its long, sensitive bill, making it vulnerable to cold weather when the ground remains frozen.
The corn crake, corncrake or landrail is a bird in the rail family. It breeds in Europe and Asia as far east as western China, and migrates to Africa for the Northern Hemisphere's winter. It is a medium-sized crake with buff- or grey-streaked brownish-black upperparts, chestnut markings on the wings, and blue-grey underparts with rust-coloured and white bars on the flanks and undertail. The strong bill is flesh-toned, the iris is pale brown, and the legs and feet are pale grey. Juveniles are similar in plumage to adults, and downy chicks are black, as with all rails. There are no subspecies, although individuals from the east of the breeding range tend to be slightly paler than their western counterparts. The male's call is a loud krek krek, from which the scientific name is derived. The corn crake is larger than its closest relative, the African crake, which shares its wintering range; that species is also darker-plumaged, and has a plainer face.
The yellowhammer is a passerine bird in the bunting family that is native to Eurasia and has been introduced to New Zealand and Australia. Most European birds remain in the breeding range year-round, but the eastern subspecies is partially migratory, with much of the population wintering further south. The male yellowhammer has a bright yellow head, streaked brown back, chestnut rump, and yellow under parts. Other plumages are duller versions of the same pattern. The yellowhammer is common in open areas with some shrubs or trees, and forms small flocks in winter. Its song has a rhythm like "A little bit of bread and no cheese". The song is very similar to that of its closest relative, the pine bunting, with which it interbreeds.
The corn bunting is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. This is a large bunting with heavily streaked buff-brown plumage. The sexes are similar but the male is slightly larger than the female. Its range extends from Western Europe and North Africa across to northwestern China.
The indigo bunting is a small seed-eating bird in the cardinal family, Cardinalidae. It is migratory, ranging from southern Canada to northern Florida during the breeding season, and from southern Florida to northern South America during the winter. It often migrates by night, using the stars to navigate. Its habitat is farmland, brush areas, and open woodland. The indigo bunting is closely related to the lazuli bunting and interbreeds with the species where their ranges overlap.
The lark bunting is a medium-sized American sparrow native to central and western North America. It was designated the state bird of Colorado in 1931.

In the United Kingdom, the term hunting with no qualification generally refers to hunting with hounds, e.g. normally fox hunting, stag (deer) hunting, beagling, or minkhunting, whereas shooting is the shooting of game birds. What is called deer hunting elsewhere is deer stalking. According to the British Association for Shooting and Conservation (BASC) over a million people a year participate in shooting, including stalking, shooting, hunting, clay shooting and target shooting. Firearm ownership is regulated in the UK by licensing. Provisions exist for those without a Firearm or Shotgun certificate to shoot under the supervision of a certificate holder.
A fecal sac is a mucous membrane, generally white or clear with a dark end, that surrounds the feces of some species of nestling birds. It allows parent birds to more easily remove fecal material from the nest. The nestling usually produces a fecal sac within seconds of being fed; if not, a waiting adult may prod around the youngster's cloaca to stimulate excretion. Young birds of some species adopt specific postures or engage in specific behaviors to signal that they are producing fecal sacs. For example, nestling curve-billed thrashers raise their posteriors in the air, while young cactus wrens shake their bodies. Other species deposit the sacs on the rim of the nest, where they are likely to be seen by parent birds.
The Sussex is a British breed of red beef cattle from the Weald of Sussex, Surrey and Kent, in south-eastern England. Its traditional use as a draught ox on the Weald continued into the twentieth century. From the late nineteenth century it began to be selectively bred for beef production. It has been exported to many countries of the world; the largest population is in South Africa, where there may be half a million head.
8967 Calandra, provisional designation 4878 T-1, is a carbonaceous background asteroid from the outer region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 13 May 1971, by Dutch astronomer couple Ingrid and Cornelis van Houten at Leiden Observatory, on photographic plates taken by Dutch–American astronomer Tom Gehrels at the Palomar Observatory in California. It is named after the corn bunting (Emberiza calandra).
Conservation behavior is the interdisciplinary field about how animal behavior can assist in the conservation of biodiversity. It encompasses proximate and ultimate causes of behavior and incorporates disciplines including genetics, physiology, behavioral ecology, and evolution.
