	The Modern Apprentice - Falconry Glossary
		It may also be done with birds during the summer months when the falconer has, for all intents and purposes, released a bird to the wild, but the bird continues to return on her own.
		Stoop The act of a bird flying high in the sky folding her wings back and dropping quickly at a bird or the lure; stooping also is used to describe lure flying where the bird is stooped to the lure making repeated shots at a lure.
		Birds who are not allowed to weather without the guard on will develop even more brittle tails as they are prevented from properly preening their tail feathers.

	Keel (bird) - Wikipedia, the free encyclopedia
		The skeleton of a dove displays a prominent keel.
		A keel in bird anatomy is an extension of the sternum which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs.
		Historically, the presence or absence of a pronounced keel structure was used as a broad classification of birds into two classes: Carinatae (from carina, "keel"), having a pronounced keel; and Ratites (from ratis, "raft" — referring to the flatness of the sternum), having a subtle keel structure or lacking one entirely.

	Keel-billed Toucan - Wikipedia, the free encyclopedia
		This social bird lives in small flocks in lowland rainforests, but as it is a poor flyer, the toucan moves mostly by hopping around trees.
		They travel in flocks of approximately six to twelve other birds, and have a family structure within their group.

		When moving the hand under the keel from front to rear, there should be one continuous unbroken contour with the keel ending as closely to the end of the vent bones as possible.
		Birds with lines or breaks in the pupil of the eye or odd eyes should be moved to the “Bad Eye” class if one is available, otherwise they should be disqualified.
		Weight for a bird in show condition should be 14 to 17 ounces for old cocks, 13 to 16 ounces for young cocks, 13 to 15 ½ ounces for old hens and 12 to 14-1/2 ounces for young hens.

	Encyclopedia article on Bird [EncycloZine] (Site not responding. Last check: 2007-10-20)
		Birds are a very differentiated class, with some feeding on nectar, seeds, insects, rodents, fish, carrion, or other birds.
		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.

	The Anatomy of Birds
		Birds are different to most mammals in a number of immediately obvious ways, they walk on two legs and have two wings, they have feathers instead of hair and a beak instead of jaws with teeth.
		The main ways birds have lost weight is through the loss of teeth and the large jaw bones needed to support teeth, the loss of nearly all the tail and reduction of the skull.
		This is missing in certain flightless birds such as the ratites (Emus and Ostriches etc.) It is also missing in Archeopteryx, however scientists believe that in the ratites the sternal keel has been lost as a result of the birds having adopted a flightless life style, whereas in Archeopteryx it had not evolved yet.

	Morphology of the Aves
		Crucial for bird flight is a canal formed by the articulation of the humerus (forewing bone), the scapula (shoulder blade), and the coracoid (bone connecting the sternum itself to the humerus).
		Bird bones are hollow and filled with extensions of the body's air sacs, which are extensions of the lungs that allow for increased respiratory efficiency.
		Bird feathers used in mate attraction may form huge crests, ruffs, or tails: the male peacock tail is a case in point.

	Bray Yacht Design and Research Ltd. - The Advantages of Twin Keels
		Modern twin keels are of high aspect ratio and present less wetted area then a full keel or long fin keel while retaining the steady helm associated with full keels.
		Both keels and rudders can be asymmetrical (more curve on one side than the other) like a wing, and tailored to work on their one specific tack.
		The relationship of keel volume to hull volume to produce constructive wave interference at the required speed and the correct toe in angle of the keels to align them with streamline flow have more to do with the success or failure of twin keels then anything else.

	Toucans Species Profiles
		Keel Billed Toucans, also known as “Rainbow Billed”, or Sulphur Breasted”, are probably the most popular species I raise.
		Keel Bills have always been hard to find, as even during the heyday of imports in the 80's, few, if any, were brought in.
		Keel Bills are definitely not a good "first bird" by any means, and do best in the hands of people with lots of "big bird" handling experience.

		Harrison's Bird Foods is a family of certified organic pet bird diets that were formulated to make your bird as healthy as it can possibly be.
		Bird does not gain weight even if fed high fat foods almost exclusively, which is one of the things we tried to get him to gain weight.
		At that point the bird was seen by Dr. Cheryl Greenacre at UGA for a second opinion on the possible PDD diagnosis (since the bird did not have whole food in droppings, and instead of a voracious appetite he has none).

		These are of interest in determining the age of birds, the ancestors of birds, the series of changes that birds underwent in evolution, whether modern birds are related to the radiation of fossil birds in the Mesozoic, and what makes a bird a bird.
		is unlike modern birds in retaining some primitive conditions shared with dinosaurs and other reptiles: teeth in jaw, curved backward; snout rather than a bill; small braincase (intermediate in relative body size between modern reptiles and modern birds) with large olfactory lobes; abdominal ribs or gastralia.
		Birds have arms at least as long as legs, longer and flightworthy feathers (though these features have been lost in some fossil and some modern flightless birds).

	Ostrich (Site not responding. Last check: 2007-10-20)
		This is a flightless bird with rudimentary wings.
		The structure of the wing is the same in principle as that found in flying birds, and the wing quills are well developed though stunted or in the form of soft feathers.
		The loss of the ability to fly was apparently caused by the increase in body weight, which resulted also in atrophy of the flight muscles and the absence of a keel on the breastbone.

		The ideal time for birding is usually early morning or late evening when the sun is less direct and birds are out feeding on insects.
		It is helpful to carry a guide on North American birds as well as guides for species found in Mexico and Central America, as the plumage on many of the birds is different while they are on their "winter holiday" in the tropics.

	Old World Aviaries: What is sick-bird syndrome?
		Typically, the owner presents a bird that is listless, with a history of rapid onset of depression with no previous indication of illness.
		The bird will respond by putting up his best front to state that, “I am well and aggressive, leave me alone.” But by surreptitiously viewing the birds, one can see signs of illness that are displayed as sick-bird syndrome.
		The reasoning behind this is that a sick bird draws the attention of predators to the flock, and the sick bird may infect others in the flock.

		Keel lesions are similar to human pressure sores and are the result of these offshore birds being on land and out of their natural habitat.
		The birds are classified according to the severity of their keel lesions on a scale of 0-3.
		Birds that have been identified as Grade 1 and 2 are monitored closely to see if they can preen their feathers over the lesion and waterproof themselves whilst ensuring that the lesion does not progress further.

	ufo - UFOS at close sight: Mothman stories in Point Pleasant, 1966: facts and fiction
		Keel himself suggests this type explanation all along his book, the only problem is that parts of his readers and certain ufologists do not care for this when they want to demonstrate that there are no extraterrestrial on board flying saucers.
		While such birds are rare to this area, Dr. Smith said this is migration time and it would not be too difficult for one or more of the birds to stop off at the wildlife refuge.
		Keel was to comment on all these failed prophecies that the "ultraterrestrial intelligence" is misleading "because" its goal is to mislead us.

		This is the only bird species in which the bill is longer than the rest of the bird.
		Hummingbirds are rather unusual birds in the relatively large size of their sternum.
		In a bird wing, the primaries are the source of thrust, and hummingbirds depend on thrust for much of their flight; the lift provided by the inner wing feathers in most birds is of little importance to hummingbirds.

		If your bird already is under a veterinarian's care, you might want to take him back in to be reevaluated.
		Your bird might have a concurrent illness or physical problem the veterinarian missed the first time around, or he may be suffering from a yeast infection caused by the antibiotics.
		A pet bird's keel may be slightly sharper than that of a wild counterpart because pets' breasts are usually underdeveloped from lack of flying.

	How To Give a Bird CPR
		CPR is much more likely to be effective if the bird has suffered from acute trauma, and conversely, it is unlikely to have a positive outcome if the bird is very debilitated and has been ill for a long period of time and the body finally gives out.
		Birds have a rapid heart rate compared to humans and dogs, so you will attempt to provide the bird with 40 to 60 compressions per minute, based on the size of the bird.
		Place one to three fingers on the keel bone (depending on the size of the bird, one finger for budgies, three for macaws) and apply finger pressure to the keel bone.

		The best way to tell if your bird is carrying an appropriate amount of weight is by looking at his breast muscle, which lies over a bone called the keel.
		If your bird is too fat, he’ll have “cleavage.” In other words, the keel bone won’t be the most prominent part of your bird’s chest.
		If your bird is too thin, he will feel bony to the side of the keel and the area alongside the keel will feel concave (curved in) rather than convex (curved out).
