Pigeon Anatomy & Physiology: 15 Facts

Although pigeons and doves are a diverse group of birds, they do share some clinically significant anatomy and physiology, including a large, bilobed crop or ingluvies, crop milk production, as well as a vascular plexus found in the subcutis of pigeons. This post also touches on specialized anatomic features unique to fruit pigeons before summarizing some features of the columbid integumentary system, musculoskeletal system, and urogenital tract.

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 Anesthesia Webinar

Dr. Lorenzo Crosta presented this live webinar on the clinical perspectives of avian anesthesia. View the RACE-approved webinar recording, then take a brief quiz to earn 1 hour of continuing education credit. After briefly reviewing clinically relevant avian anatomy and physiology, Dr. Crosta touches upon injectable anesthesia, then discusses in detail preanesthesia and inhalation anesthesia in clinical practice. The discussion then moves onto monitoring the avian patient, from vital parameters to capnography, doppler, electrocardiography, and pulse oximetry. Dr. Crosta also discusses analgesia, intra-operative fluid therapy, as well as specific concerns related to avian anesthesia, such as positioning the patient, hypocalcemia, air sac cannulation, as well as management of diving birds. This seminar concludes with practical tips for safe and uneventful patient recovery.

Critical Care Techniques for Avian Wildlife Emergencies

Dr. Heather Barron presented this webinar on avian critical care. View a recording of the live, interactive event, then take the brief post-test to earn 1 hour of continuing education credit. The goal of wildlife medicine is always eventual release and therefore triage of avian wildlife may vary based on case load, regulations, and the presenting situation. Dr. Barron examines the guidelines used to set triage policy and the reasons a bird may not be releasable or have a good quality of life in captivity. She then discusses practical measures intended to alleviate suffering and improve the odds of patient survival, such as fluid support, analgesia, evaluation of blood volume, and transfusion. This presentation concludes with a brief discussion on assessing life and euthanasia.

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.

The Parrot Brain On Shapes: Similarities with Human Visual Processing

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”…

Pigeon Disease Primer

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.

Order Columbiformes: Species and Breeds

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.

Pigeon Fancy: Talking the Talk

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.

Presenting problem: Oropharyngeal Plaques in Birds

Oropharyngeal lesions tend to be asymptomatic until lesions are quite advanced. Clinical signs associated with oropharyngeal disease vary, but may include anorexia, dysphagia, drooling, halitosis, head or food flicking and rubbing the beak. Diffuse disease or large focal lesions or diffuse disease can obstruct the choanal slit and/or glottis leading to wheezing, open-mouth breathing, dyspnea or in extreme cases suffocation…

Crop Stasis in Birds

The crop or ingluvies is a diverticulum of the esophagus present in many but not all, bird species. The crop serves as a food storage organ, regulating the flow of food through the gastrointestinal tract. Food within the crop is also softened by mucus glands. Crop stasis is a common clinical sign in which the crop fails to empty in a timely manner…

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…

Fungal Disease in Avian Patients

Fungi are among the most common causes of infectious disease in captive birds, and fungal diseases can be challenging to diagnose, as well as treat. Because fungi are typically opportunistic, causing non-contagious disease in susceptible individuals, prevention and treatment require an understanding of etiology as well as predisposing factors.

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.
