![]() ![]() Many other birds throughout the world have been shown to have St. The most common and troublesome infestations are found in canaries and Lady Goldian finches. These infections of bronchopneumonia, bronchietasis, streptoccus and other pathogenic organisms along with pulmonary emphysema are the main cause of death. The open sores left by the feeding mites are the entry points of secondary infections. Although the mites keep the birds in a weakened condition, the death rate is low. Some die in the nest while others live for years. Resistance varies widely among individuals. Death will soon result unless the bird quickly becomes calm and relaxed. Panic then sets in, which further increases oxygen demand along with an increased, heart beat. This is due to a strong oxygen demand and an attempt to clear the airways for sufficient air passage. On occasion a moderate or severe case will, when excited, bend its head back while doing back flips on the cage floor. Infested individuals often become very lethargic, puffed, and demonstrate obvious signs of labored breathing. In more advanced cases, in cool, damp weather, or when the bird becomes more active, these symptoms can be heard several feet away. This is due to the mucus formed around the mite. The noise of air moving through the mite obstructed trachea can be heard as a wet asthmatic sound when the beak or chest is placed near the ear. Will frequently wipe their bills and hold it open while breathing. The infested birds will cough while trying to rid themselves of the irritation. It is also possible, although very improbable, these mites could be passed in the drinking water and even more improbable on common feeding areas. Their spread is associated with direct bill contact during the mating season and while feeding the young. However, many of this family (rhinonyssid) are viviparous and go through larva, nymph and adult stages all within the same host. Very little is known about their life cycle. Both had lateral leg extension of 59 microns to 61 microns. Females were studied at a length of 590 microns and a width of265 microns with a larger full abdomen and a radial arrangement of the legs. More spcci [ical ly males have been studied at a length of 400 microns and a width of200 microns with all eight (8) legs directed anteriorly or anterolaterally. As true blood suckers their appearance darkens as they gorge with theīlood or their host I'hcir size is such as to be the smallest speck visible to the naked eye, and then only when gorged and on a light background. These mites appear almost clear to dark red, depending upon how recently they last fed. An attempt is made Lo put forth useful information taken from a file over two reams thick, gathered at an expense in excess of$5,000, after thousands of man hours of work and thousands of miles traveled. It is the result of nine basic studies plus an additional 14 substudies and experiments. The following chapters describe, in brief, much of what was learned during the next ten years. Handicapped without a medical background and realizing the odd-, against success, I S\\ ore a personal vendetta to rid myself of these "Bugs". But while gathering information on how to do so, air-sac mites came into the picture.ĭuring 19 all my Lady Gouldians and my best canaries died of these mites. The obvious remedy was Lo breed this OUL of them. In 1964 I began to notice many of my Canaries and Lady Gouldians hadĪsthma. It is with this in mind that this paper is being written and dedicated only to those who are interested in and practicing their private hobby of aviculture. Thus, those who have the most to gain may do so, while the industry who saw fit not to make the investment, will not make the profit. It is, therefore, left to the private sector to fill this gap by developing their own data, while reserving its use for the private aviculturist. The commercial development of avian medicine is seen by the industry to have a low profit potential and thus not deserving of their capital investment. ![]() This lack of information is nowhere more apparent than in the field of avian medicine. Throughout the world there are individuals actively practicing their private hobby of aviculture without adequate scientific data. ![]()
