Avian Anatomy and Physiology Basics

This article is the focus of LafeberVet’s Avian Anatomy Teaching Module, which is RACE-approved for 1 hour of continuing education credit. This review begins with a brief summary of Class Aves before exploring various organ systems. Important vocabulary terms and key concepts are emphasized throughout the text. The reader should have a basic understanding of mammalian anatomy. Birds are quite different both structurally and functionally when compared to mammals, therefore comparisons are frequently drawn between these two taxonomic groups. Since form follows function, descriptions of avian anatomy will also merge into physiology and other life sciences, where appropriate. Clinically relevant information and additional resources on LafeberVet are also highlighted.

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.

Information sheet 

Basic Information Sheet: Finch

Finches are found worldwide. The Zebra finch, Owl finch and Gouldian finch are originally from Australia where large flocks may be found, mainly in arid grassland areas. Owl finches are also found in woodlands and scrublands.  The Bengalese or Society finch is a cross between the sharp-tailed munia and striata munia and was never found in nature.  Of family Fringillidae, only the Red Siskin and the Yellow Siskin are listed in Appendix I and Appendix II of Convention on International Trade in Endangered Species (CITES) listings respectively. Appendix I species are threatened with extinction, and commercial trade is prohibited and importation/exportation for scientific research requires special permits. Appendix II species are not necessarily threatened with extinction, but may become so unless their trade is strictly regulated.

Basic Information Sheet: Canary

Originating from the Canary Islands, the canary’s song captured the attention of Europeans, who started importing these birds in the late 1500’s. Although breeding for desirable traits has produced many variations, the wild canary is a small, green bird. Free-ranging populations are strong and are found in a wide variety of habitats, which is why the canary was placed in the International Union for Conservation of Nature (IUCN) Red List category of “Least Concern”.

Restraint of Wild Birds

In the best of captive situations, wild birds are still subject to significant stress. This is particularly true during phases of rehabilitation that require frequent capture and treatment. Experience with individual patients will dictate your approach to capture and restraint, but be aware that a slow, careful approach to capture followed by restriction of vision during restraint will generally yield best results.

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.
