	Bird ringing (Research) - arocha, international, cross-cultural, Christian, faith, God, Biblical, creation, community, ...
		Each ring has a unique number engraved on it as well as an address to which it can be sent by a member of the public in the event that the bird is found dead or injured.
		Ringing has been going on for over fifty years in many countries all over the world, and the information gained from it has enabled scientists to extend their knowledge of bird biology, migration and ecology in ways that would not otherwise be possible.
		Because bird ringing is a complex and delicate operation and one that could involve harm to the birds, it is strictly controlled and in most countries requires an official license.

	BTO - General information on ringing
		Ringing allows us to study how many young birds leave the nest and survive to become adults, as well as how many adults survive the stresses of breeding, migration and severe weather.
		Ringing allowed us to show that declines in the number of Sedge Warblers breeding in Britain and Ireland was linked to lower levels of rainfall in their African wintering quarters.
		Many studies have shown that birds ringed during the breeding season quickly return to incubating eggs, or feeding chicks, once they are released, and long distance migrants continue to travel thousands of miles between breeding and wintering grounds.

	Bird Ringing Centre - Naturhistoriska riksmuseet
		Bird ringing, as a scientific method, is very important for our knowledge about reproduction, migration and survival rates in many bird species and every recovery report is valuable.
		The ringing data and recovery reports are stored in several databases and archives and used for analyses and research on birds and, for example, environmental issues.
		The Bird Ringing Centre publishes, on an annual basis, a report on the birds ringed and recovered during a previous year and an atlas based on recoveries of Swedish ringed birds is under production.

	How ringing works - The Royal Society for the Protection of Birds
		Bird ringing is the process of fitting a small ring onto a bird's leg.
		The ring is fitted, details of the species, its age and its condition and the location it is being ringed in are noted and then the bird is released as soon as possible.
		Bird rings are designed by the BTO (British Trust for Ornithology), and are made of lightweight metal that does not harm the bird.

	Bird ringing - Wikipedia, the free encyclopedia
		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 are either ringed at the nest, or after being trapped in fine mist nets, Heligoland traps, duck decoys or similar.
		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.

	Ringing - Wikipedia, the free encyclopedia
		Ringing is undesirable because it causes extra current to flow, thereby wasting energy and causing extra heating of the components; it can cause unwanted electromagnetic radiation to be emitted; and it may cause unwanted triggering of bistable elements in digital circuits.
		Ringing in the ears commonly follows exposure to loud noises, and is a sign of damage to the hair cells of the inner ear.
		Bird ringing is using individually-numbered small metal leg rings placed on birds' legs to track their activity.

	Bird - Wikipedia, the free encyclopedia
		Most birds are diurnal, or active during the day, but some birds, such as the owls and nightjars, are nocturnal or crepuscular (active during twilight hours), and many coastal waders feed when the tides are appropriate, by day or night.
		The basal bird Archaeopteryx, from the Jurassic, is well-known as one of the first "missing links" to be found in support of evolution in the late 19th century, though it is not considered a direct ancestor of modern birds.
		Birds have a body plan that shows so many unusual adaptations (mostly aiding flight) that birds have earned their own unique class in the vertebrate phylum.

	The Ultimate Bird Dog Breeds Information Guide and Reference
		Birds are bipedal, warm-blooded, egg-laying vertebrates characterized primarily by feathers, forelimbs modified as wings, and hollow bones.
		Birds respire by means of crosscurrent flow: the air flows at a 90 degree angle to the flow of blood in the lungs capillaries.
		Birds posses a ventriculus, or gizzard, that is composed of four muscular bands that act to rotate and crush food by shifting the food from one area to the next within the gizzard.

	Ringing
		It is essential birds are not affected unduly by the ring; studies have shown birds quickly return to their normal lifestyles once released.
		Around 800,000 birds are ringed in Britain and Ireland each year, and about one in fifty birds are subsequently reported to the BTO, so every report of a ringed bird is valuable.
		It is often possible to watch the ringing process, providing we have enough staff both ring the birds and explain the process to visitors.

	Birding in India - Bird Migration - Bird Ringing - Bird Banding
		Generally, in birds, migration is seasonal, and in the Indian subcontinent the majority of migratory birds are winter migrants.
		It is important to remember that until the 19th century optical equipment was extremely rare, bird identification guides non-existent, travel to other countries difficult and expensive and bird ringing of course had not been invented.
		Thus while the birds' internal clock probably releases the hormonal triggers at a fairly accurate date each year, the availability of food and the presiding weather conditions decide when the migration starts and hence when we see the first spring migrants arrive and the last autumn ones leave.

		Bird Ringing has been going on for about 90 years in Britain and Ireland and its main focus today is to keep track of population numbers.
		Ringing is only carried out by highly trained volunteers, and the ring itself is so light it feels about as heavy as a watch does on a human arm.
		Some birds are ringed in the nest, or in nest boxes, but most are ringed using mist-nets which are very fine nets about 60 feet long and ten feet high, such as the ones at the Northmoor Trust.

		Most current ringing (banding) in the county involves members of the Munster Ringing Group, and all ringing is by qualified ringers holding an appropriate permit from the British Trust for Ornithology and a licence from the National Parks and Wildlife Service.
		Ringing activities cover a range of habitats, and include mist-netting of migrant and other passerines at reedbed, scrub and garden sites, and nestbox ringing of chicks.
		Recoveries of metal-ringed birds are dominated by two species (Storm Petrel and Sedge Warbler) which are targeted by ringers throughout Europe, resulting in many 'controls' (birds recaptured away from original ringing site and released after ring-details are recorded).

	Watching Birds with Your Ears, by Diane Porter
		The birds sing like mad on a spring morning, but most of the music is over by the time the sun rises.
		Each species makes sounds that are unique to itself, and you can identify the birds by those sounds just as easily as you can by their shape or color.
		Birds' strongest senses are sight and hearing, and they communicate by using visual and sound signals.

	Bird Ringing
		Each person involved in the ringing of birds has to go through a rigorous training programme with highly experienced ringers before becoming licensed by the British Trust for Ornithology (BTO) to ring birds on their own.
		If a ringed bird is caught or found (as a result of traffic, cats, deaths in gardens etc.) again, the information on the ring is recorded and sent to the BTO who monitor these ‘recoveries’.
		The Ringing Scheme has built up a vast amount of information over the years about the birds that occur in Britain and the BTO plays a key role in conservation of our birds and their habitats.
