Old World quail: Old World quail is a collective name for several genera of mid-sized birds in the pheasant family Phasianidae.Plasmodium hermani: Plasmodium hermani is a parasite of the genus Plasmodium subgenus Huffia.Chimera (EST): In genetics, a chimera is a single cDNA sequence originating from two transcripts. It is usually considered to be a contaminant in transcript and expressed sequence tag (EST) databases.Red Feather Development Group: Red Feather Development Group is a non-profit organization that builds straw-bale homes on American Indian reservations.Chicken as biological research model: Chickens (Gallus gallus domesticus) and their eggs have been used extensively as research models throughout the history of biology. Today they continue to serve as an important model for normal human biology as well as pathological disease processes.Ovomucin: Ovomucin is a trypsin inhibitor found in raw egg white.Tadorninae: The Tadorninae is the shelduck-sheldgoose subfamily of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans.Bird trapping: Bird trapping techniques to capture wild birds include a wide range of techniques that have their origins in the hunting of birds for food. While hunting for food does not require birds to be caught alive, some trapping techniques capture birds without harming them and are of use in ornithology research.Architectonica perdix: Architectonica perdix, common name the partridge sundial, is a species of sea snail, a marine gastropod mollusk in the family Architectonicidae, the sundials.Eggshell: An eggshell is the outer covering of a hard-shelled egg and of some forms of eggs with soft outer coats. Bird eggshells contain calcium carbonate and dissolve in various acids, including the vinegar used in cooking.Truncal neural crest: The truncal neural crest or trunk neural crest is a form of neural crest.Influenza A virus subtype H5N1: Influenza A virus subtype H5N1, also known as A(H5N1) or simply H5N1, is a subtype of the influenza A virus which can cause illness in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent of H5N1 flu, commonly known as avian influenza ("bird flu").Mesenchyme: Mesenchyme is a type of tissue characterized by loosely associated cells that lack polarity and are surrounded by a large extracellular matrix. Mesenchymal cells are able to develop into the tissues of the lymphatic and circulatory systems, as well as connective tissues throughout the body, such as bone and cartilage.Acromelanism: Acromelanism is a genetically determined, temperature-dependent pigmentation pattern, with full expression only occurring on legs, ears, tail and face. Seen in Siamese and Himalayan cats, rats, and rabbits.
