Abdomen The portion  of the body that lies between the thorax and the pelvis Abdominal cavity  The space that contains the abdominal viscera (the liver, spleen, intestines, etc.). Absorption To take in a substance through the pores or cells of a tissue. The substance must pass through the tissue to be absorbed. Acaracides Substances, such as pesticides, that kill mites. Acute Sharp or severe, such as an illness with a sudden onset and a relatively short course Agate In coloured canaries, the dilute bronze mutation. Air-sacs  Thin-walled sacs that communicate with the lungs and are part of the avian respiratory system. Airsacculitis  Inflammation of the air sacs in birds Air-sac mites Albinism A group of inherited conditions which include a decrease in the amount of pigment in the eyes, skin and feathers Algae  A special form of plant life that lacks true roots, stems, or leaves, and that ranges in size from microscopic single cells to multicellular structures, such as seaweeds. Alimentary canal - The digestive tract Allele  Just a specific variation of a gene Allergic disease  Development of a hypersensitivity of the host to substances foreign to the body, primarily antigens and other proteins Altricial   Refers to newly hatched birds that require care in the nest for some period of time. Ambient temperature  Room or environmental temperature. Amino acids  Organic compounds of specific composition from which proteins are synthesized. Anaerobic  Absence of oxygen; often refers to an organism that grows, lives, or is found in an environment devoid of oxygen, such as the cellular form of Clostridium botulinum, which causes avian botulism. Analgesia  The absence of normal sensitivity to pain, typically, being in a semiconscious state induced through an anesthetic. Anemia A reduction in the normal number of red blood cells, or erythrocytes, in the body. Anesthetic A drug used to temporarily deaden pain Animal pathogens Organisms such as viruses, bacteria, and parasites, that are capable of invading and infecting animal hosts and causing disease Anorexia  Lack of appetite. Anoxia A total lack of oxygen caused by several mechanisms that prevent oxygen from reaching the mitochondria of cells. Anoxia indicates a level of oxygen in animal tissues that is below normal in the presence of an adequate blood supply. Antibody A specialized serum protein produced by the immune system in response to an antigen in an attempt to counteract the effects of the antigen; antibodies in the blood indicate exposure to specific antigens or disease agents. Antidote  Substances that counteract or prevent the action of a poison. Antigen - Any foreign substance (generally proteins) to which the body reacts by producing antibodies. Antigens may be soluble substances such as toxins, particulate matter such as pollen, or microorganisms such as bacteria and viruses. Antiserum  A serum containing antibodies to specific antigens; can be used to test biological samples f or the presence of specific antigens. Antitoxin Any substance that counteracts the action of a toxin or poison; generally, a specific type of antibody produced in experimental animals as a result of exposure to a specific toxin. Botulism antitoxin, for example, can be produced by exposing an animal to l ow levels of botulism toxin over a long period of time and then harvesting serum from that animal to treat other animals. Arbovirus A virus that is transmitted by invertebrates of the phylum Arthropoda [insects, arachnids (spiders, mites, ticks, etc.) and crustaceans]. Arthropoda To the large phylum “Arthropoda” belongs invertebrate animals, such as insects, spiders, crustaceans, and their relatives. They have a segmented body, an external skeleton, and jointed limbs, and are sometimes divided among several phyla. To  the phylum “Arthropoda” belongs insects, spiders (arachnids), ticks and also mites. Ascites  Accumulation of fluid in the abdominal cavity. Aseptic  Free from infection; sterile. Asexual reproduction  The formation of new individuals without the union with cells of the opposite sex and usually by an individual. Asymptomatic  Without visible signs of illness; an asymptomatic carrier is an organism that harbors a disease agent, but that shows no outward signs. Ataxia Incoordination Autosomal Referring to a chromosome, other than of the sex (X or Y) chromosomes. Avi abbreviate for Avian Avicides Chemical substances used to kill or repel birds. Avirulent Not virulent, does not cause disease.
Bald FaceBacterin A vaccine consisting of killed bacteria that is used for protection against infection by a specific bacterial disease. Bacteriophage A virus that infects a bacterium. Bacterium Singular for bacteria. Any of a group of microscopic, unicellular organisms that have distinct cell membranes and that lack a distinct nucleus surrounded by a nuclear membrane. Bald face A serious blemish in the Lizard canary in which the cap encroaches upon the face and cheeks of the birds. Beak The bird’s bill is called beak. Benefits Benefits are advantages or profits derived as a result of an action. Birds for breeding or rearing This are birds which are domesticated or confined species. Birds of prey  Synonymous with raptors; includes eagles, hawks, falcons, kites, and owls Blood feather A new feather that has not finished growing. If a blood feather damaged, it can lead to significant bleeding. The bleeding can be stopped when the feather is pulled. Such operations, especially in bigger birds (parrots, parakeets) should only be carried out by the vet. Broken Capped  A category in the Lizard canary in which the bird’s light cap is broken to a greater or lesser extent by dark feathering. Bronze In coloured Canaries the black melanistic pigmentation. Brooding Care of young birds by the adult. Brood Parasites Birds which lay their eggs in the nests of other species, leaving the chicks to be reared by unwitting foster parents. Brown In coloured Canaries the brown melanistic pigmentation. Buff Canaries have two feather types. The lipochrome pigment in a Buff canary stops just a short of the margin of the web of the feather giving the bird a lightly powdered or frosted appearance. Also called a non-intensive canary. In the white mutations you will find this feather types, too, but it is not easy to see the different Bumblefoot An inflammation and, often, swelling of the foot of birds as the result of a bacterial infection. Bursa of Fabricious A saclike outgrowth of the cloaca of birds that is part of the avian immune system
