The National Bird and a common favourite, the Robin is easily recognised by most people.
The Robin is a plump bird with bright orange-red breast, face, throat and cheeks edged with grey, a white belly and olive-brown upper parts.
The sexes are very similar, if not identical, though some texts suggest that the brown forehead is "V" shaped in females, and "U" shaped in males, though even this is not always apparent. They have a brown bill and legs.
The juvenile Robin has speckled buff-brown upper parts and underparts. They have no red feathers so that adult birds do not attack them in territorial disputes. The speckled feathers are lost in a partial moult when the bird is about two to three months old.
In the winter, resident birds are joined by immigrants from continental Europe, mostly from Scandinavia; these Robins are paler than ours, have a duller red breast. The immigrants are also generally less tame because they skulk in woodlands, only British Robins are a tame garden bird.
Robins are territorial all year round; during the spring and summer this territoriality is for breeding, but at other times individual robins hold territories for feeding. Robins will defend their territories to the death, and so in the poem "Who killed Cock Robin?", another Robin rather than a sparrow would be more likely:
Who killed Cock Robin?
I said the Sparrow,
With my bow and arrow,
And I killed Cock Robin.

ornithology, a branch of zoology dealing with the study of birds. Most of the early writings on birds are more anecdotal than scientific, but they represent a broad foundation of knowledge, including much folklore, on which later work was based. In the European Middle Ages many treatises dealt with the practical aspects of ornithology, particularly falconry and game-bird management. From the mid-18th to the late 19th century, the major thrust was the description and classification of new species, as scientific expeditions made collections in tropical areas rich in bird species. By the early 20th century the large majority of birds were known to science, although the biology of many species was virtually unknown. In the latter half of the 19th century much study was done on the internal anatomy of birds, primarily for its application to taxonomy. Anatomical study was overshadowed in the first half of the 20th century by the rising fields of ecology and ethology (the study of behaviour) but underwent a resurgence beginning in the 1960s with more emphasis on the functional adaptations of birds.
Ornithology is one of the few scientific fields in which nonprofessionals make substantial contributions. Much research is carried out at universities and museums, which house and maintain the collections of bird skins, skeletons, and preserved specimens upon which most taxonomists and anatomists depend. Field research, on the other hand, is conducted by both professionals and amateurs, the latter providing valuable information on behaviour, ecology, distribution, and migration.
Although much information about birds is gained through simple, direct field observation (usually aided only by binoculars), some areas of ornithology have benefited greatly from the introduction of such instruments and techniques as bird banding, radar, radio transmitters (telemeters), and high-quality, portable audio equipment.
Bird banding (or ringing), first performed early in the 19th century, is now a major means of gaining information on longevity and movements. Banding systems are conducted by a number of countries, and each year hundreds of thousands of birds are marked with numbered leg bands. The study of bird movements has also been greatly aided by the use of sensitive radar. Individual bird movements are also recorded on a day-to-day basis by the use of minute radio transmitters (telemeters) worn by or implanted inside the bird. Visual markings, such as plumage dyes and plastic tags on the legs or wings, allow visual recognition of an individual bird without the difficult task of trapping it and allow the researcher to be aided by amateur bird-watchers in recovering his marked birds. Research into the nature and significance of bird calls has burgeoned with the development of high-quality, portable audio equipment.
