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 […]
Regurgitation versus vomiting
The terms “regurgitation” and “vomiting” are often used interchangeably in the avian patient. Regurgitation is the passive expulsion of contents from the esophagus or crop (Fig 1). Vomiting is the expulsion of ingesta from the proventriculus, ventriculus, or intestines. It is not always possible to make a distinction in the clinical patient […]
Be prepared for your next bird patient. Review the basic approach to the avian physical examination, including history, review of signalment, and visual examination. Key parts of the exam will vary, but generally include a body weight in grams, the oropharynx, crop, sternum, coelom, and vent. The fundus should be routinely evaluated in trauma […]

Complete blood count
Survey whole body radiographs
Additional tests based on clues gathered:
Serology &/or PCR testing: Chlamydophila psittaci, avian polyoma virus, aspergillosis, psittacine beak and feather disease, avian bornavirus, etc.
Gram stain cytology
If diagnosis remains inconclusive, consider referring the patient to an avian specialist.
Regardless of the […]
Anorexia may be the only indication of poor health in the critically ill bird and by the time other clinical signs are apparent disease may be quite advanced. This means that all reports of poor appetite in the avian patient must be taken very […]
[…] a complete history and providing supplemental oxygen, the bird may improve enough to handle an abbreviated physical examination. Although it is prudent to gather supplies for all avian exams, it is particularly important for the bird with respiratory disease. It is also wise to have oxygen available for the dyspneic patient. Always warn the […]

Heavy metal toxicity
Heavy metal toxicity is the most common form of poisoning reported in avian medicine.
Lead is ubiquitous in the environment, and parrots seem to be attracted to its malleable nature (Box 1).

Historically, routine Gram’s stains were performed in apparently healthy birds. As our understanding of avian medicine has grown, avian veterinarians have questioned the reliability and validity of Gram’s stain cytology as a screening test. Cytology is indicated when specific problems are reported during a detailed medical history or […]

Did you know polyomavirus has been characterized in the Eurasian jackdaw (Corvus monedula)? Called crow polyomavirus, or CPyV, this virus is closely related to avian polyomavirus. The clinical significance of CPyV is not yet known (Raidal 2012, Zielonka 2012).

Unfortunately the sedentary lifestyle of the companion bird makes obesity one of the most common forms of malnutrition seen in clinical practice. Pet birds are fed too much food or they are fed diets rich in sources of fat, such as sunflower seeds […]

Understanding crop burn The crop, or ingluvies, is a diverticulum of the esophagus present in many but not all, bird species (Fig 1). The crop serves as a food storage organ, regulating the flow of food through the gastrointestinal tract. Figure 1. The crop (arrow) is a diverticulum of the esophagus present in many avian […]
[…] There are at least 14 recognized breeds of miniature pigs, including the Vietnamese potbellied pig, the Juliana pig, the KuneKune, and others.

Diagnosis of otitis
Obtain a detailed history:
Determine the onset and duration of disease.
Is there a history of any prior illness, especially respiratory disease?
Ascertain the possibility of exposure to toxins or parasites.
Is there a history of trauma?
How is the animal’s food and water […]
