The “Pigeon Disease Primer” explores important differential diagnoses for common clinical problems observed in pigeons and doves. Although the clinical approach to the columbiform relies on the same concepts of “One Medicine” used in all species, many of the infectious diseases of pigeons are relatively unique to this taxonomic group, or at least much more prevalent when compared to psittacine birds or songbirds.
Although pigeons and doves are a diverse group of birds, they do share some clinically significant anatomy and physiology, including a large, bilobed crop or ingluvies, crop milk production, as well as a vascular plexus found in the subcutis of pigeons. This post also touches on specialized anatomic features unique to fruit pigeons before summarizing some features of the columbid integumentary system, musculoskeletal system, and urogenital tract.
Many people have been curious about the way we at International Bird Rescue were able to clean the birds affected by the San Francisco Bay Mystery Goo Spill in January 2015.
Head tilt or torticollis, also known as “wry neck” and uncontrolled or episodic rolling are common presentations in the pet rabbit (Oryctolagus cuniculus). There are two common causes of head tilt or torticollis and rolling in the rabbit…
The sugar glider (Petaurus breviceps) is a small marsupial native to Australia and New Guinea. Although sugar gliders lack marsupial bones, also known as epipubic bones or pelvic ribs, female gliders or “dams” possess a pouch or marsupium. Like all marsupials, the glider gives birth to a fetus, which completes development inside the pouch…
Self-mutilation is sometimes observed in isolated sugar gliders or in situations causing social stress. Improper groupings are common in captivity as pet owners often combine a male with one or two females, without realizing that not all individuals get along…
Red leg syndrome, also known as “pink belly disease” or bacterial dermatosepticemia, is one of the most common clinical conditions of captive frogs. Associated with peracute to acute bacterial septicemia, red leg is generally a disease of captive animals although the condition has also been implicated in rare mass mortalities of wild amphibians. This presenting problem article reviews clinical findings in red leg syndrome, pathogenesis of disease, as well as key points of urgent care and prognosis. The basics of case management are then reviewed: differential diagnoses, diagnostics, treatment, prevention and control.
The non-hyphal, zoosporic, chytrid fungus Batrachochytrium dendrobatidis (Bd) has caused widespread and dramatic population declines in both wild and captive amphibians worldwide. Use this table to review the basics of the infectious disease chytridiomycosis

Part of a unique series on sea turtle veterinary medicine and wildlife rehabilitation, this article explores many components of the sea turtle physical exam. Evaluation of the shell is discussed in both cheloniids and leatherbacks (Dermochelys coriacea) as well as assessment of the cardiopulomonary system, skin, long bones and joints, cloaca and tail. Evaluation of the coelom by inguinal palpation is described as well as measurement of body temperature. Specialized testing such as neurologic and in-water examinations are also described. Common physical examination findings like fibropapillomas in green turtles (Chelonia mydas) and epibiota in loggerhead turtles (Caretta caretta) are also discussed. LOGIN to view references.
Primarily a disease of captive reptiles, dysecdysis is sporadically seen in free-ranging reptiles. Among captive reptiles, difficult sheds are most common in those with a complete shedding cycle: snakes and some geckos such as the leopard gecko and African fat-tailed gecko. Some skinks with relatively tiny digits, are prone to retaining shed skin on the digits.
Although fungal disease is uncommon in small mammals, dermatophytosis is the most common mycosis seen in clinical practice. Despite the low incidence of clinical disease, rodents are common asymptomatic carriers of dermatophytes. Fungal pathogens are generally more important for their zoonotic potential. Rodents are frequently asymptomatic carriers of ringworm, and transmission of disease to human caretakers is not uncommon.
Beak trauma is a common problem in the companion parrot. Beak injury most often occurs secondary to bird bites and other forms of aggression. Other potential causes include damage from inappropriate caging or toys and iatrogenic damage during…
Thermal burns are a common injury in snakes and lizards. Companion snakes and lizards may come in contact with poorly protected heat sources or old “hot rocks” that short circuit. Even free-ranging reptiles may be at risk for thermal injuries during grass or forest fires. This presenting problem article “Burns in Snakes and Lizards”, explores a basic understanding of burns in reptiles, then moves onto key points of urgent care as well as general aspects of case management, including patient history, physical examination, differential diagnoses, diagnostics, therapy, and finally prognosis.
Traumatic wounds are seen in exotic animals, and are particularly common in wildlife patients. Proper initial management of the wound is critical for a successful outcome and rapid healing, and an understanding of anatomy of the skin and physiology of wound healing is necessary for effective treatment.
Traumatic wounds are frequently seen in exotic animals, and are particularly common in wildlife patients. Appropriate wound management of wounds has significant impact on healing time and success.
Signs of avian polyomavirus type 1 in the budgerigar parakeet can be quite variable. Feather dystrophy or abnormal feather growth can lead to deformed flight feathers. Affected birds are unable to fly and are called “runners” or “creepers”. “French molt” is a term sometimes used for this slow, debilitating disease in parakeets characterized by progressive development of abnormal feathers. Bleeding is another hallmark of clinical avian polyomavirus infection…
Bite wounds are not confined to small animal practice. Bite wounds are a common and significant problem in clinical practice, and LafeberVet’s presenting problem article features urgent care tips for this universal problem of veterinary patients. The incidence of bite wounds increases with a history of exposure to the outdoors or to other animals. The owner may even report a fight or interaction that results in a bite wound.

Approach to the passerine bird relies on the same concepts of “One Medicine” used in all animals. Nevertheless many of the infectious agents diagnosed in songbirds are relatively unique to this taxonomic group, or at least much more prevalent when compared to psittacine birds or birds of prey.
Free-ranging sugar gliders live in the treetops and glide from tree to tree using their patagium like a kite and their tail as a rudder to control the direction of flight. The patagium is a furred membrane of skin or gliding membrane that stretches between the forelimbs and hind legs. These skin folds are extensions of the lateral body wall. When the glider is at rest, this excess skin appears as a rippled border along the sides. During a glide, the skin spreads out to form a rectangle…
Waterfowl belong to Order Anseriformes. Virtually all anseriforms belong to family Anatidae, which consists of ducks, geese, and swans. If you are comfortable with psittacine anatomy and physiology, then many features of waterfowls will be familiar. LafeberVet has listed twelve interesting and clinically significant facts about waterfowl…
Order Galliformes consists of heavy-bodied, ground feeding birds like the chicken, turkey, quail, and pheasant. Backyard or hobby flocks consist of meat and game birds; or ornamental or show birds. Conditions commonly encountered in backyard chickens and turkeys often include endoparasites like Eimeria spp., pasteurellosis or fowl cholera, mycoplasmosis, staphylococcosis, and colibacillosis. Another common presenting problem is trauma, which can typically be categorized as…
Order Galliformes is a large, diverse taxonomic group with a worldwide distribution. More than 250 species have a chicken-like appearance and short, rounded wings. LafeberVet has listed twelve interesting and clinically significant facts about galliform anatomy and physiology including important vocabulary terms.
Although the rare veterinarian routinely deals with large numbers of waterfowl on a regular basis, many avian veterinarians encounter waterfowl only sporadically as wildlife rehabilitation cases, backyard poultry, and/or zoo specimens. When consulting textbooks for help, often a dizzying array of waterfowl diseases are encountered. Some conditions such as “angel wing” and predator trauma are important in captive populations, while infectious diseases like fowl cholera can cause massive die-offs in free-ranging birds…
Like other shedding problems, retained spectacles or “eye caps” are a sign of an underlying problem related to patient health or husbandry. If retained spectacles are not removed, they can interfere with vision, damage the eye, and/or serve as a source of infection
Many companion parrot species originate from tropical environments with high humidity in which they bathe often. Even parrots from arid environments enjoy and benefit from bathing. Bathing stimulates preening and is essential for normal feather health. In fact, inadequate bathing and low humidity have often been linked to feather picking. Use this client education handout to explore bird bathing methods as well as Do’s and Don’t’s to encourage the pet bird to bathe or shower.
Feather destructive behavior represents a range of actions from excessive preening to feather plucking or feather picking to self-mutilation.
Flamingos belong to order Phoenicopteriformes and family Phoenicopteridae. There are six different kinds of flamingos. The greater or American flamingo has the widest distribution, however the Chilean flamingo is the most numerous and widespread of the South American species. Explore LafeberVet’s collection of fascinating flamingo facts.
Feather picking is the most frustrating behavioral condition in pet birds from both the veterinarian’s and the owner’s perspective. This client education handout, donated by Dr. Eric Klaphake, explains that feather picking is a symptom and not a particular disease. Potential causes of feather picking are summarized and possible veterinary tests and treatment recommendations are listed.
Do you have everything? Shared by registered veterinary technician and veterinary technician specialist, Jill Murray of Oklahoma State University, review our collection of procedure equipment checklists. Checklists are used in clinical practice to make preparation for procedures more efficient and more consistent, thereby improving the quality of care. Use these equipment checklists to train students and staff, or simply to jog your memory for procedures performed only sporadically.
Grooming in the bird can refer to clipping wing feathers, trimming nails, and smoothing and/or trimming the beak. Grooming can be performed by the veterinarian or an astute, skilled veterinary technician, however before the procedure begins one must always ask should the bird be groomed and should the bird be groomed at my practice?
A relaxed, comfortable bird may briefly fluff out its feathers before its plumage again appears flat and sleek. The critically ill bird may exhibit persistently fluffed and ruffled plumage…
Why is a broken blood feather an emergency? When the blood feather breaks, the feather shaft acts like a straw making the vessels bleed much longer than they would otherwise due to capillary action. The degree of blood loss can be significant, particularly in small birds. Use this video clip or article with still images to review the basic structure of the blood feather, key points of urgent care as well as follow-up care.
The pathogenesis of otitis is often multifactorial in the rabbit. Predisposing factors such as ear conformation increase the risk of otitis in certain breeds. All rabbits have a relatively narrow ear canal, however in Lop-eared rabbits the fold in the ear cartilage is such that the lumen is entirely closed off preventing normal drainage of cerumen from the ear.
Most species of mites are host-specific, however take special precautions, such as wearing exam gloves, to minimize the spread of potentially zoonotic pathogens. Humans that become infested with Sarcoptes scabei may develop wheals, vesicles, papules, and intense pruritus. Pet owners, especially children, may become infected with…
Donated by Dr. Eric Klaphake, this client education handout describes psittacine beak and feather disease (PBFD), an important disease of parrots. This handout discusses the cause of PBFD, bird species at greatest risk, transmission, as well as diagnosis or testing. Recommendations for removal of PBFD from a collection or aviary are also described.
LafeberVet’s collection of avian anatomical diagrams features the beak and eye, various images illustrating plumage and topography, as well as the musculoskeletal system.
Burns are common in avian medicine. Many burns result from contact with hot liquids such as scalding water or cooking oil. Electrical burns arise from chewing on electrical wires and burns may also occur when pre-weaning birds are fed hot formula. Burns resulting from entrapment in burning buildings or inside containers, such as chick incubators with burning bedding, are not as common but are much more difficult to treat due to the complication of smoke inhalation.
