I... more Pododermatitis is a disease of the integument of the plantar (bottom) surface of a bird’s foot. It can also spread to the dorsal (top) surface of the foot. It is caused by irritation, trauma, poor perching, or overweight. It will become progressively worse unless it is treated aggressively. There are seven stages of progression of the disease; the last is so severe that the bird’s foot might need to be amputated. Treatments consist of medical intervention in the early stages and surgical intervention in the later stages. The sooner the affliction is addressed, the more likely are the chances of full recovery.
Caring for your avian companion, 2022

There are many excellent websites for you to explore. Remember, nothing can take the place of your avian veterinarian's guidance. And you will need to use your own common sense, as there are areas in which even the veterinarians disagree, such as in feeding and reproduction. Educate yourself completely so you know what to look for as far as signs of illness, behavioral issues, and the nutritional needs of your bird.
The effects of tobacco use on birds. Revised Sept. 10, 2022. Includes Handout for Bird Owners Who Smoke, 2022

They are proven to cause not only respiratory distress and disease, but they are also responsible for illnesses in every other body system. Second-and third-hand smoke are the most common causes of tobacco-related diseases; however, other forms of tobacco and nicotine products cause damage as well--damage that includes injury to the cardio-vascular system, respiratory system, feathers, integument, and gastrointestinal system. Unless the disease is too advanced, removal of the bird from the toxic environment, along with medical management, will usually result in a resolution of the clinical signs and healing of damaged tissue.
Hand-raised or Parent-raised: Which is Better for the Birds?, 2022

The trend of hand-rearing began in the 1980’s when thousands of birds were taken from their habitats and placed around the world. In most countries, hand-raising because the acceptable method of breeding since the parents weren’t tame, and breeders feared they would not know how to raise the chicks in captivity. It has done irreparable damage to both the parents and chicks over the decades. Breeders need to allow the parents to once again take charge of the rearing of their chicks, which is much easier on the humans as well.
The Importance Of Removing Leg Bands On Birds, 2022

Bands can catch on toys or cage parts, cut into the bird’s leg and foot, cause the bird to self-mutilate or even chew off his own leg to be rid of the band. Today, there are alternatives to keeping the band on after purchase or adoption; one of them is microchipping. It is done by an avian veterinarian. Others are discussed in the paper.
Overview of Avian Geriatric Disorders with Emphasis on Psittacines, 2022

Determining if a bird is geriatric is based on the species’ average life expectancy. Up until more recently, there have not been enough geriatric birds of most commonly kept species available, either wild-caught or raised in captivity, to be able to study them; therefore, it had not been known at what age changes in their physical and mental health begin to occur. Although tables with lifespans have been published, other factors influence lifespans, such as nutrition, genetics, and exercise. These can either accelerate or delay changes related to aging. Consequently, geriatric, as it relates to birds, is the age at which medical conditions associated with aging are being documented and reported. As they age, birds will suffer from many of the same ailments that humans and other mammals do. Avian veterinarians are seeing more and more geriatric birds in their practices, as the larger birds which were purchased in the 1980’s and 1990’s reach the end of their lifespans, and the smaller birds, living longer than they had in the past, reach the end of their lifespans also. The illnesses they develop affect their behavior and mental states.

As they age, birds will suffer from many of the same ailments that humans and other mammals do. Avian veterinarians are seeing more and more geriatric birds in their practices, as the larger birds which were purchased in the 1980's and 1990's reach the end of their lifespans, and the smaller birds, living longer than they had in the past, reach the end of their lifespans also. The illnesses they develop affect their behavior and mental states. Images 1, 2 This 92-year-old parrot was passed down through several generations in the same family (images courtesy Hub Pages; http://hubpages.com/animals/From-the-parrots-beak-910edition). 1.2 Rate of Senescence in Birds Bird species are strikingly long-lived compared to humans and other animals. "Many species live up to three times longer than mammals of equal body mass. The slow rates of senescence experienced by birds is a paradox. They have very high metabolic rates, high body temperatures, and blood-glucose levels. Their blood glucose levels are two to four-times greater than mammals. Their lifetime energy expenditures are up to 15 times higher than those of mammals. According to current biochemical theories of aging, birds should experience accelerated tissue damage as a result of the damaging byproducts of oxidation." 2, 29 Instead, birds age more slowly and gradually because of adaptations they have developed for preventing tissue damage due to oxidation and "their unusual capacity for neuroregeneration in the brain." 2,28,29 The oxidative-damage theory suggests that "Species who are oxygen-reactive during normal oxidative metabolism processes undergo molecular changes and age-related declines. The fact that birds age slowly, despite high energy expenditures over a lifetime, suggests that birds possess special adaptive defenses against oxidative damage." 29 These adaptations allow birds to age very slowly until the end time of their lives. At that point, senescence occurs quickly. This slower rate of senescence in birds has been documented with data from those in charge of zoo populations, veterinarians who see pet birds, and aviculturists who have tagged and recaptured wild birds and followed them throughout their lives. Birds maintained in captivity experience age-related changes that are not all that different from those in mammals; these changes just occur later and more gradually in birds. 28 2 Lifespan and Longevity The average lifespan of a bird is the life expectancy for that particular species. Longevity refers to the maximum lifespan that can be expected under ideal conditions. Many birds never reach their maximum lifespans nor even get close to reaching them. According to C. Greenacre, "The lifespan of a bird depends on its species, genetic inbreeding, size, concurrent disease, diet, and environment." 20 Some of the more commonly seen geriatric diseases and conditions are arthritis, neurological disease, heart disease, neoplasia, obesity, atherosclerosis, chronic malnutrition, chronic aflatoxin exposure (carcinogenic mycotoxins, or mold-spore diseases), and cataracts. If these diseases had been caught earlier, many of the birds would have had longer lifespans. 44 Until recently, geriatric medicine has been a neglected area of avian medicine. Infectious diseases, inadequate diets, and poor care meant that most pet birds did not live long enough to develop geriatric conditions. However, as the knowledge base of avian medicine has increased, so have the lifespans of pet birds. S. Austed states that, "Most pet birds have the potential to live 20-80 years, depending on their size (larger birds live longer than smaller ones), diet (herbivores live longer than carnivores or omnivores), and socialization (highly social species live longer than solitary species)." 3 2.1 The Effect of Flight on Lifespans In birds, species that are capable of flight live considerably longer than non-flying species of similar body size. "This could be because flight enables animals to escape some of the environmental dangers they encounter, such as predators or destruction or deterioration of their 10-15 12 Image 7.

Most studies are based on chicken requirements because their physiology is closely related to psittacines' physiology. Since there are hundreds of psittacine species, it is impossible to develop specific requirements for them. Vitamins, minerals, and guidelines for daily food choices are included in this paper.

The quality of life for these birds depends on the timeliness of presentation to an avian veterinarian and the correct diagnosis and treatment of these tumors and growths. Neoplasms vary in both the type of tumor and the species in which they are found. Some neoplasms are easily removed surgically, while others present challenges to the practitioner and the owner. While chemotherapy and radiation therapy have been attempted, most practitioners agree that surgical debulking and removal, if possible, are the preferred means of treatment.

The bird was clinical with the disease, and the author describes how she cared for the bird during this time. The paper covers foods, environmental triggers, and the importance of exercise in the day-to-day life of these birds so that they might live as healthy a life as possible. This paper is an addendum to the paper, Understanding Avian Bornaviral Ganglioneuritis and Avian Ganglioneuritis, already in the Academia files.

It is extant in Australia and many Asian countries and can be found around the world. It is highly infections and environmentally stable. PCR testing offers conclusive proof of the virus in birds. It robs the birds of all their feathers. There is no treatment and no cure. It is eventually always fatal.

ABG and Avian Ganglioneuritis may have the same symptoms are both treated in the same manner and with the same medications. The virus is passed vertically and is not easily transmitted to other birds. Testing must be done by PCR molecular diagnostics to avoid false positives and negatives. Given proper treatment, an ABG bird can live a normal life for several years.

Over time they will grow, and eventually the bird will die from internal and subcutaneous bleeding. Diet and medication will diminish them if they are not allowed to become too large. I have developed a message technique to shrink and eliminate these growths. This will take a long time, but if caught early, the growths will eventually be resolved without surgical intervention. The technique is explained in the paper.
