Bird ringing (also known as bird banding) is an aid to studying wild birds, by attaching a small individually numbered metal or plastic ring to their legs or wings, so that various aspects of the bird's life can be studied by the ability to re-find the same individual later. Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. This can include migration, longevity, mortality, population studies, feeding behaviour, and many other aspects. Bird migration refers to the regular seasonal journeys undertaken by many species of Birds Bird movements include those made in response to changes in food availability

Terminology and techniques
Those who ring birds are called "bird ringers" in the UK or in some parts of Europe; elsewhere it is referred to as "bird-banding", as the shape is more band-like, than ring-like. The Ruby-crowned Kinglet ( Regulus calendula) is a very small Songbird of the Kinglet family Regulidae native to North America. Organized ringing efforts are called "ringing schemes" and the organizations that run them, "ringing authorities". Birds are "ringed" (rather than "rung"). In most of the world, except the UK and parts of Europe, those that "band" birds are known as "banders" and are active at "banding stations".
Birds are either ringed at the nest, or after being trapped in fine mist nets, Heligoland traps, drag nets, cannon nets, or similar methods. A bird nest is the spot in which a Bird lays and incubates its eggs and raises its young Mist nets are used by ornithologists to capture wild Birds for banding or other research projects A Heligoland trap (or funnel trap) is a large building-sized funnel-shaped rigid structure used to trap Birds so that they can be ringed or otherwise
A ring of suitable size is attached (usually made of aluminum or other light-weight material), and has on it a unique number, plus a contact address. The bird is often weighed and measured, examined for data relevant to the ringer's project, and then released. The rings are very light-weight, and have no adverse effect on the birds. The individual birds can then be identified when they are re-trapped, or found dead.
When a ringed bird is found, and the ring number read and reported back to the ringer or ringing authority, this is termed a "ringing recovery" or "control". The finder can contact the address on the ring, give the unique number, and be told the known history of the bird's movements. Some national ringing/banding authorities also accept reports by phone or on official web sites.
The organizing body, by collating many such reports, can then determine patterns of bird movements for large populations. Non-ringing/banding scientists can also obtain data for use in bird related research.
History
The earliest attempt to mark a bird was by one Quintus Fabius Pictor. This Roman officer, during the Punic Wars around 218-201 BC, was sent a swallow by a besieged garrison. The Punic Wars were a series of three wars fought between Rome and Carthage between 264 and 146 BC and were probably the largest wars yet of the ancient He used a thread on its leg to send a message back. A knight interested in chariot races during the time of Pliny (1 AD) would take swallows to Volterra, 135 miles away and release them with information on the race winners. [1]
Falconers in the Middle Ages would fit plates on their falcons with seals of their owners. From around 1560 or so, swans were marked with a swan mark, a nick on the bill.
Ringing of birds for scientific purposes was started in 1899 by Christian Mortensen, a Danish schoolteacher. He used zinc rings on European Starlings. Zinc (ˈzɪŋk from Zink is a Metallic Chemical element with the symbol Zn and Atomic number 30 The European Starling, Common Starling or just Starling, Sturnus vulgaris, is a Passerine Bird in the family The first ringing scheme was established in Germany in 1903 at the Vogelwarte in Rossiten on the Baltic Coast. This was followed by Hungary in 1908, Great Britain in 1909 (by Arthur Landsborough Thomson in Aberdeen and Harry Witherby in England), Yugoslavia in 1910 and the Scandinavian countries between 1911 and 1914. Sir Arthur Landsborough Thomson ( October 8, 1890 - June 9, 1977) was a Scottish Ornithologist. Henry Forbes Witherby MBE FZS MBOU ( October 7, 1873 -; known as Harry) was a noted British Ornithologist, author publisher England is a Country which is part of the United Kingdom.

Wing tags
In some surveys, involving larger birds such as eagles, brightly-coloured plastic tags are attached to birds' wing feathers. The Great Frigatebird ( Fregata minor) is a large dispersive Seabird in the Frigatebird family. Each has a letter or letters, and the combination of colour and letters uniquely identifies the bird. These can then be read in the field, through binoculars, meaning that there is no need to re-trap the birds. Because the tags are attached to feathers, they drop off when the bird moults. In Biology, moulting (or molting, also known as shedding or for some species Ecdysis) signifies the manner in which an animal routinely Imping is the practice of replacing a bird's normal feather with a brightly-colored false feather. A patagial tag is a permanent tag held onto the wing by a rivet punched through the patagium. In Bats, the Skin forming the surface of the wing It is an extension of the skin of the abdomen that runs to the tip of each digit uniting the forelimb with the
Radio transmitters and satellite-tracking
Where detailed information is needed on an individuals' movements, scientists can fit tiny radio transmitters to birds. For small species the transmitter is carried as a 'backpack' fitted over the wing bases, and for larger species it may be attached to a tail feather or temporary leg band. Both types usually have a tiny (10cm) flexible aerial to improve signal reception. Two field receivers (reading distance and direction) are needed to establish the bird's position using triangulation. Transmitters may be recovered by recapturing the bird or designed to drop off. The technique is useful for tracing individuals during landscape-level movements particularly in dense vegetation (such as tropical forests) and for shy or difficult-to-spot species, because birds can be located from a distance without visual confirmation. The use of satellite transmitters for bird movements is currently restricted by transmitter size - to species larger than about 400g. They may be attached to migratory birds (geese and swans are popular subjects) or other species undergoing longer-distance flights. Bird migration refers to the regular seasonal journeys undertaken by many species of Birds Bird movements include those made in response to changes in food availability Individuals may be tracked by satellites for immense distances, for the lifetime of the transmitter battery. As with wing tags, the transmitters may be designed to drop off when the bird moults; or they may be recovered by recapturing the bird.
Field-readable rings
A field-readable is a ring or rings, usually made from plastic and brightly coloured, which may also have conspicuous markings in the form of letters and/or numbers. They are used by biologists working in the field to identify individual birds without recapture and with a minimum of disturbance to their behaviour. Rings large enough to carry numbers are usually restricted to larger birds, although if necessary small extensions to the rings (leg flags) bearing the identification code allow their use on slightly smaller species. For small species (e. g. most passerines), individuals can be identified by using a combination of small rings of different colours, which are read in a specific order. Most colour-marks of this type are considered temporary (the rings degrade, fade and may be lost or removed by the birds) and individuals are usually also fitted with a permanent metal ring.

Other markers
Head and neck markers are very visible, and may be used in species where the legs are not normally visible (such as ducks and geese). The Herring Gull, Larus argentatus, is a large Gull (up to 26 inches or 66 cm long and is the most abundant and best known of all gulls along the shores of Nasal discs and nasal saddles can be attached to the culmen with a pin looped through the nostrils in birds with perforate nostrils. They should not be used if they obstruct breathing. They should not be used on birds that live in icy climates, as accumulation of ice on a nasal saddle can plug the nostrils. Neck collars made of expandable, non-heat-conducting plastic are very useful for larger birds such as geese.
