Capnometry in Exotic Animal Species

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.

Monitoring Vital Signs in Exotic Animal Species

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.

Wait For It…A Grey Parrot Demonstrates Self-Control

“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.

Explore the history of similar research in children and animals as well as the specific results of the study led by Adrienne E. Koepke of Hunter College and Suzanne L. Gray of Harvard University. Also learn more about Dr. Irene Pepperberg and the fascinating work of The Alex Foundation.

Avicultural Medicine: Visiting the Facility

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.

Calcium in the Avian Patient

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.

Pediatric Avian Medicine: Infectious Diseases of the Psittacine Chick

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.

Fascinating Facts on Foraging and Enrichment

Foraging, the act of searching for and finding food, makes up a significant part of the wild parrot’s day. In the wild, most animals, including psittacine birds, spend a significant part of their daily activity on foraging. In fact, many free-ranging parrots regularly travel several miles between feeding sites in search of food. Once wild parrots arrive at a feeding site, a wide variety of foraging behaviors are observed including searching, manipulating, as well as consuming food. Depending on the species and the season, time invested on these behaviors can range from…

Grooming Companion Birds: A Review

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?

Parrot Handling and Restraint

Manual restraint and handling is required for most medical procedures in the companion parrot, also known as the psittacine or hookbill. Warn owners of the inherent risk of handling the critically ill bird and minimize handling time so the bird does not overheat or become overly distressed. Also monitor the bird closely for any change in strength, breathing, or attitude. Parrot handling also carries potential risk for veterinary medical staff since even friendly birds may bite if they feel threatened.

Foraging as a Means of Behavior Modification

Foraging is the act of searching for and finding food. Many wild birds spend more than 50% of their day foraging and feeding, particularly in the morning and evening. Because foraging occupies a significant portion of a bird’s daily activity, it likely has social and behavioral importance.

Bird behaviors can be divided into four categories: foraging, socialization, grooming or self-preening, and sleeping or resting. In a captive situation, normal behaviors are likely disrupted including foraging. If the ability to forage is removed, that leaves socializing, grooming, and rest…

Diagnosing and Treating Avian Neurologic Disease

The cranial nerve exam differs little from that of mammals, however there are differences in innervation. As in mammals, menace and pupillary light response (PLR) require use of cranial nerves II (optic) and III (oculomotor), however menace is difficult to interpret in birds. Also, PLR may be overridden in birds due to the presence of striated iridal muscle. Evaluate PLR early in the exam using a sudden, bright light directed toward the medial canthus. Consensual PLR is absent due to…

Avian Respiratory Emergencies: An Approach to the Dyspneic Bird

After recognizing a dyspneic bird, the clinician’s initial response should be: Hands Off!! Dyspneic birds can die soon after presentation with the additional stress of restraint and handling. Therefore minimize handling and place the bird in an oxygen-rich cage. Humidify air and provide 40 to 50% oxygen. As in mammals, oxygen therapy is potentially toxic if given for prolonged periods at high levels.
