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.

Avian Hematology and Biochemistry Panels

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…
