Capnometry measures the maximum value of carbon dioxide (CO2) obtained at the end of expiration or end-tidal carbon dioxide (ETCO2). There is good correlation between ETCO2 and arterial CO2 in birds and mammals and capnography can be used as a reliable tool to evaluate the adequacy of ventilation in these species. Capnography can only be used to identify trends in reptiles because of cardiac shunting of blood past the reptilian lungs.
Even the most steadfast and seasoned veterinary anesthetist can find themselves intimidated by exotic animal patients. Standard veterinary anesthesia monitors are not designed to read the extremely high (or extremely low) heart rates and respiratory rates of some exotic animal patients. Despite these challenges, valuable information can be gathered from monitoring tools as well as hands-on techniques. Essential vital signs, such as heart rate and rhythm, respiratory rate and depth, body temperature, and mucous membrane color should all be evaluated.
Arterial blood pressure is a function of heart rate, blood volume, stroke volume, and arterial compliance. Indirect arterial blood pressure is most commonly measured by Doppler ultrasound or non-invasive oscillometric monitors. What are the limitations of indirect blood pressure measurements in exotic animal patients? How is this technique unique in exotic companion mammals when compared to dogs and cats? How is this technique performed in birds and can this procedure be used in reptiles?
Electrocardiography can be used to detect and diagnose arrhythmias and conduction abnormalities, particularly during long-term anesthesia. How are leads attached to exotic animal patients? And what is the normal appearance of normal electrocardiogram tracings in birds or reptiles?
Heart rate and oxygenation should ideally be monitored during every anesthetic event. Patient size can limit the accuracy of pulse oximetry readings in exotic companion mammals and this technique has not been validated in birds or reptiles, however trends during the course of anesthesia can still provide useful clues to patient clinical status.

This learning aid is designed to assist the participant in meeting the needs of VECCS-certified facility. The basics of emergency medicine and critical care universal, however veterinarians face a unique set of challenges when caring for birds, exotic companion mammals, and reptiles. Level 1 of this teaching module reviews the basics of exotic animal critical care. To learn more in Level 2, review the key points on critical care or supportive care for each taxonomic group: birds, exotic companion mammals, and reptiles. Each summary page includes a brief quiz that tests your knowledge and reinforces fundamental principles. Delve deeper into critical care of exotic animal patients in Level 3 by browsing pertinent exotic animal content on LafeberVet.
Poisonings are relatively uncommon in companion bird emergency medicine, but these conditions do occur and can involve a wide assortment of toxins. In principal, treatment in birds is the same as for other animals. First, stabilize the patient presented with abnormal clinical signs. Establish an airway, initiate respiration, and address cardiovascular needs.
There is little empirical information available on cardiopulmonary resuscitation in most exotic animals. Fortunately, the basic principles of CPR are the same for all species, however there are important species-specific considerations. This review article explores techniques for establishing airway control, ventilation and cardiac compression recommendations as well as considerations for emergency drug selection.
Although the principles of emergency medicine critical care are universal for all species, this approach must be balanced with an understanding of the unique aspects of avian medicine. Use this summary page to review the basic approach to the avian patient and select additional links to supplement your knowledge base.
Although patient history is important in all species, improper diet and substandard housing are often major contributors to illness in non-traditional pets. This means that a detailed and accurate history is often one of the most critical diagnostic tools for the exotic animal patient. This review focuses on birds, reptiles, and small exotic companion mammals, beginning with the signalment and presenting complaint, before moving onto the environmental history, dietary history, and of course the medical history.
Test your knowledge after completing the avian portion of the LafeberVet Emergency and Critical Care teaching module.
Signs of illness in birds are often quite subtle until disease is advanced. Fortunately, quite a bit of information can be gleaned from a detailed history and careful observation. View this brief slideshow for tips on the visual examination.

This webinar recording is RACE-approved for 1 hour of continuing education. Despite parrots being popular pets, much of the information regarding their nutritional and behavioral needs is still unknown. Unlike dogs and cats, most psittacine species are not domesticated and have therefore likely retained most, if not all, of their wild instincts and behavioral needs. In captivity, however, most parrots have little to no opportunity to perform these species-typical behaviors. This will not only reduce their welfare, but can also result in the onset of abnormal repetitive behaviors, including feather damaging behavior, and oral or locomotor stereotypies.

Placement of an enteral feeding tube is a recognized method of supportive care, and the esophagostomy tube is an accepted route that is generally well tolerated by avian patients and relatively easy to place. In clinical patients, esophagostomy tube placement has been described in psittacine birds, raptors, and ostriches.
Esophagostomy tube placement is indicated in cases of severe beak trauma or disease, as well as diseases of the oral cavity or proximal esophagus, such as abscesses and neoplasia. Esophagostomy tubes may also be used to…
Objects are often not fully visible in everyday life. Human beings are capable of processing the complex visual information related to “incompleteness” because our visual environment is primarily composed of opaque objects that can overlap and partially hide each other. Scientists believe that many nonhuman species are also able to deal with “incompleteness”…

View a recording of this web-based seminar presented by Terry Campbell, MS, DVM, PhD. Cytology is a simple, rapid diagnostic procedure requiring little in terms of equipment and cost to the veterinarian. Most clinical veterinarians are familiar with sample collection techniques for domestic mammals; which also apply to the small exotic mammals. Common cytological specimens used in avian and reptilian medicine include: aspirates, imprints of biopsy material, tracheal washes, crop (ingluvies) aspirates or washes in birds, gastric washes in reptiles, sinus aspirates, lung washes in reptiles, aspiration of coelomic fluid, and fecal smears.
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.
Pigeons and doves belong to order Columbiformes and family Columbidae. Within family Columbidae, there are five subfamilies consisting of 42 genera and 308 species. Pigeons and doves are found on every continent except Antarctica, and they live in virtually all types of terrestrial habitats. Columbids tend to be stocky birds with relatively small heads, short beaks, as well as a fleshy cere and a bare ring of skin around the eyes. Columbiforms also tend to have short, squat legs and long keels.
This practice of pigeon fancy is generally called “pigeon racing” in North America and “pigeon play” in Europe. The principles of pigeon fancy are intricate and there are a variety of vocabulary terms that seem quite mysterious. There is also a history of resistance to veterinary involvement among many pigeon breeders so it can be intimidating for even experienced avian veterinarians to interact with the pigeon fancier.
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.
Traumatic orthopedic injuries are relatively common in the avian patient. Although bird bones are strong when intact, they tend to shatter on impact as the cortices are thin and brittle. A lack of abundant soft tissue coverage often leads to open fractures…
All raptors consume a meat-based diet ranging from the specialist diet of the fish-eating osprey (Pandion haliaetus) to a generalist diet that can include insects, mammals, birds, reptiles, amphibians, and even carrion. Other than poultry, the exact nutritional requirements of birds are unknown, however the natural raptor diet is always relatively high in protein and fat and low in carbohydrates. Whole prey diets have a calcium/phosphorus ratio of 1.5:1 as the bird actually consumes the bones as well as the meat…

View the recording of this free, interactive webinar, presented by Neil Forbes, BVetMed DECZM (Avian) FRCVS. Many sick or injured exotic animals are presented in critical condition. More of these patients can be saved by appropriate fluids and nutritional support, than by any single medical or surgical procedure. In practical terms, providing this support is often easier said than done. Dr. Forbes’ presentation serves to demystify some of the challenges encountered; practical solutions for all exotic patients are described and discussed.
“Griffin”, a grey parrot in Dr. Irene Pepperberg’s animal behavior and avian cognition lab, could wait up to 15 minutes for a better quality reward, even though both treats offered were preferred food items. Griffin displayed delayed gratification for longer than any previously tested avian subject including Goffin’s cockatoos. Fifteen minutes was the longest time evaluated, not necessarily the longest length of time Griffin could wait.

This webinar recording was made by Lynne Seibert, DVM, MS, PhD, Dipl. American College of Veterinary Behaviorists. Feather destructive behavior, also called pterotillomania, is one of the most common and frustrating behavior problems seen in captive psittacine birds. The disorder is characterized by feather removal, feather chewing, or self-inflicted trauma to soft tissue, limited to areas that the bird can reach. Behavioral history-taking should include information about the bird’s background, early rearing environment, caregiver expectations, composition of the household, air quality issues, changes in the environment associated with onset of the behavior problem, exposure to chemicals, the cage, toys, and photoperiod, nutrition, and social interactions.

It is 10 p.m. in your veterinary emergency hospital and a dreaded call comes in. A panicked owner is in tears because their beloved pet is in crisis. In most cases, your team will quickly gather supplies and move swiftly to prepare for the emergent patient. This patient may strike fear in many veterinary professionals, however, because it is the dreaded avian patient presenting to a general veterinary practice.
Released for National Veterinary Technician Week 2014, Tips and Tricks for the Avian Patient is part of an Exotic ICU series that provides advice on the management of birds in a critical care setting.
Wing injuries may present as a wing droop or an inability to fly. The figure-of-eight bandage, or wing wrap, is the standard method for stabilizing the wing short-term. See the NEW and improved version of LafeberVet’s wing wrap placement video clip.
Proventricular dilatation disease or PDD is one of the most frustrating avian conditions encountered today. The recent discovery of a causal relationship between PDD and avian bornavirus has not simplified the challenges that are faced. The detection of avian bornavirus infection is common in birds with PDD but is also detected in birds with other chronic diseases that are not diagnosed with PDD. Proventricular dilatation disease was first reported in the late 1970s…
Because of a lack of identified blood groups in companion bird species, compatibility for transfusion is based on the use of major and minor cross matches. A major cross match is performed by mixing donor red cells with recipient plasma and a minor cross match uses recipient cells and donor plasma. The appearance of agglutination or cell lysis indicates incompatibility.
Unlike mammals, a single transfusion between different bird species can be safe and efficacious. Transfusions will be most effective if the donor is…
Leg bands are sometimes used for identification of birds. Band removal is indicated as a medical treatment when the band is associated with tissue swelling due to trauma or a build up of keratin. Prophylactic band removal is recommended by some veterinarians because of the danger of the band catching on wire or toys. There is some controversy, however, as to whether bands truly pose a significant risk. Most clinicians agree that closed bands pose less risk of injury compared to…
Reproductive emergencies are most commonly seen in small psittacine birds like the cockatiel, lovebird and budgerigar parakeet. This article reviews conditions commonly seen on an emergency basis such as dystocia, egg yolk peritonitis, cloacal or oviductal prolapse, and/or chronic egg laying. Pertinent anatomy and physiology as well as case management, including the reproductive history, physical examination, diagnostic imaging, and behavioral modification techniques are also discussed.

If the gut works, use it. The preferred route for providing nutrition is enteral feeding since this preserves intestinal structure and function. Parenteral nutrition is indicated to prevent malnutrition when patients cannot consume adequate nutrients by oral feeding or tube feeding or when the respiratory tract cannot be protected. Parenteral nutrition is 100% bioavailable since nutrients reach tissue without the variations associated with gastrointestinal digestion.
Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs) that comprise a small percentage of dietary lipids ingested by humans and animals. The name “omega-3” refers to the location of the double bond closest to the methyl end of the hydrocarbon chain, and may be alternatively referred to as “n-3” in the literature. Chief among the omega-3 fatty acids is…
Body condition scoring or BCS is a useful tool for assessment of a patient’s general health status and evaluation of a patient’s food supply. The BCS system described below is based on scores between 1 and 5, with 1 being emaciated and 5 being obese for the “generic” bird. Currently there is no universally agreed upon BCS system for the avian patient due to…
The site visit allows the veterinarian to appreciate intricate facility details. Unless there is an emergency, schedule visits during the non-breeding season and only visit one site daily to prevent potential iatrogenic contamination of facilities. I usually schedule appointments in the morning prior to going to the clinic. An aviary map or blue print of the aviary layout will help you visualize where birds are in relation to each other.
Birds are in trouble worldwide. One in eight bird species are threatened with extinction, and even common species are declining. Only species able to flourish in altered habitats or supported by intervention techniques have stable or improving populations. Notable successes in North America include the California condor, bald eagle, whooping crane, peregrine falcon, and the Puerto Rican parrot. These species could not have increased in number over the last two decades without the perseverance and diligence of interdisciplinary conservation teams. There are many conservation teams that can use your avian veterinary medical skills and experience…
A bird is a wing guided by an eye… Rochon-Duvigneaud: Lex Yeux et La Vision Des Vertebres
The avian eye is a large structure that takes up a significant portion of cranial mass. Raptors depend heavily on vision in order to compete successfully for survival. The posterior aspect of the eye fits snugly within the large bony orbit. The globes are separated by a thin interorbital septum, which measures significantly less than 1 mm in some areas…
High levels of vitamin A are found in foods of animal origin in the form of retinyl esters. Liver, fat, fish liver oils, and egg yolk are particularly good sources of vitamin A. Some plants and insects are also good sources of carotenoids. The dietary carotenoids found in dark, leafy greens and…
Quarantine is a basic component of good preventive medicine. The purpose of quarantine is to protect both the existing collection and the new arrival. New birds are usually stressed and may be more susceptible to infectious diseases. The quarantine period also allows the new bird(s) to acclimate to its new environment, food, and owner. Proper client education is paramount to minimize and/or eliminate the risk of infectious disease outbreaks.
One of the most valuable items in avian practice is a reliable formulary. Although pharmacokinetic and pharmacodynamic data is slowly growing, the vast majority of drug doses in companion parrot medicine rely on extrapolation and/or clinical experience. It is crucial that the clinician have access to this wide range of information and experience.
The gastrointestinal tract acquires and digests food, absorbs nutrients and water, and expels unabsorbed ingesta as feces. Nutritional support of the avian patient with gastrointestinal (GI) disease is challenging. In cats and dogs, it is easy to “rest” the gut, however with their relatively high metabolic rate, this is difficult, if not impossible, to achieve in many avian patients. Specific disease conditions increase the difficulty regulating gastrointestinal motility including ingluvitis (crop stasis). …
The avian patient poses special challenges for delivery of injectable medications. Although the techniques involved are not unique to birds, special knowledge of avian anatomy as well as delicate, proficient technical skills are required. Depending on the species, the individual, and the clinical situation, injections can be delivered by intramuscular, intravenous, intraosseous, subcutaneous, intratracheal, or intracoelomic routes. Parenteral drug administration provides the advantage of delivering a precise dose when a rapid therapeutic response is necessary. Disadvantages include stress as well as the potential irritation or pathology that can occur at the injection site.
There are various approaches to provide food for the companion parrot. Each nutritional strategy has its own advantages and disadvantages including seed-only diets, pelleted diets, extruded diets, and/or foraging diets.
There are a number of potential nutritional problems that can promote renal disease. Excess dietary protein, excess dietary calcium, hypovitaminosis A, or hypervitaminosis D may lead to nephritis or other degenerative renal changes…
In mammals, chronic liver disease is often associated with decreased intake of food, mainly due to anorexia, nausea, and vomiting, as well as taste abnormalities, and the same appears to be true for the avian patient. Chronic liver disease may also lead to maldigestion and malabsorption, as well as metabolic abnormalities such as increased protein and lipid catabolism, glucose intolerance, depletion of hepatic glycogen stores, and decreased glucose oxidation. Therefore chronic liver disease may lead to significant malnutrition and weight loss, particularly in patients with severe hepatic dysfunction…
Diarrhea is a common clinical presentation in avian medicine. Diarrhea may be caused by a variety of conditions, however it is particularly important for the practitioner to understand the anatomy and diseases of the avian gastrointestinal tract and associated organs.
Blood work is considered a basic diagnostic test in every species, including birds. Venipuncture may be indicated for wellness screening, sample collection for DNA sexing, evaluation of the ill or injured bird, as well as collection of blood for transfusion. The value of testing must always be weighed against the stress of venipuncture since the critically ill bird may not be stable enough for restraint. This article reviews equipment needed, the volume of the blood sample, general tips for blood collection, common venipuncture sites in the bird, and sample handling.
The most widespread mineral in the body, calcium is required for normal metabolism and bone mineralization.
Physiology
Calcium homeostasis is under the control of calcitonin, which is produced by the ultimobranchial gland, vitamin D, and parathyroid hormone. In laying hens, most dietary calcium is used for egg production. Rising estrogen levels promote increased intake of calcium supplements like cuttlefish bone and calcium-rich foods, however the quantity of calcium ingested daily is insufficient for the massive deposition of calcium required for eggshell calcification.
A clinical trial was conducted with cockatiels to compare a whole-seed balanced diet (Nutri-Berries) with that of a pelleted diet. Blood values, body weight, and other parameters were measured to assess the alternative diet’s clinical effects on birds.

In 1998, an expert committee met to discuss the nutritional needs of companion birds. The purpose of the meeting was to discuss and develop nutrient profiles for companion birds, focusing on profiles for formulated feed.
The expert panel developed maintenance guidelines for two broad groups of birds: psittacines and passerines (regardless of size or genus). These conservative, generalized guidelines are extrapolated from the National Research Council requirements for poultry and…
Psittacosis or ornithosis is caused by Chlamydophila psittaci, an obligate intracellular bacterial infection of birds. Chlamydophila psittaci may be excreted in feces and oculonasal discharge. Chlamydophila is environmentally labile but remains infectious for months in organic debris. Latently infected birds appear healthy but shed the organism intermittently for months to years. Stressors such as breeding, shipping, crowding, or climatic extremes may activate shedding.
Although hematology and biochemistry are an important part of the clinical picture in the avian patient, this bloodwork remains just ‘part of the picture’. All too often, when a clinician is unfamiliar with a species, the reaction is often to rely on laboratory results to hang a diagnosis upon. Although we have all been guilty of this, such an approach is inappropriate. For each sick bird, the following diagnostic tools should be applied: complete history, visual examination of the bird and its environment, physical examination, clinical pathology sample collection (blood, feces, swabs, aspirates, etc.), and radiography.
White blood cells are similar to mammalian lines, except that mammalian neutrophils are replaced with heterophils and mammalian platelets are replaced with thromobocytes. There are significant variations in normal differentials among avian species, in particular the total white cell count and…
Pediatrics is one of the most fascinating and rewarding fields of avian medicine. The key to hand raising healthy psittacine chicks is a strong preventive medicine program based on sound husbandry practices. Physical examination is an important part of preventive health care.
Regardless of the initial cause of illness or injury, neonatal psittacine birds often develop secondary bacterial and/or fungal infections that can become serious primary problems. These infections are most commonly encountered within the gastrointestinal tract.
The key to hand raising healthy psittacine chicks is a strong preventive medicine program based on sound husbandry practices. Hygiene, hand feeding protocols, incubation and brooder parameters, environmental temperature in the nursery, and pest control are just a few of the husbandry practices that; if mismanaged, can lead to serious adverse consequences.
Many experienced aviculturists follow strict husbandry protocols that result in few health problems. When problems do arise…
Although Gram-negative bacteria and non-budding yeast can be normal gastrointestinal flora in the psittacine bird, these organisms can quickly overgrow in the debilitated chick. Signs of clinical disease can first manifest as crop stasis or stunting. A wide range of agents can cause problems, however important infectious diseases in the juvenile psittacine bird include avian polyomavirus, psittacine beak and feather disease, and candidiasis.
Behavior is the most direct tool a wild bird has to respond to its environment, and it ultimately determines whether it survives and breeds in its natural environment. There are two functional categories of avian behaviors: self-maintenance behaviors and social behaviors.
Feeding excessively hot formula (>110°F) causes crop burns. This problem is particularly common when formula is heated in a microwave without thorough mixing. Early signs of crop burn include…
