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.
All raptors consume a meat-based diet ranging from the specialist diet of the fish-eating osprey (Pandion haliaetus) to a generalist diet that can include insects, mammals, birds, reptiles, amphibians, and even carrion. Other than poultry, the exact nutritional requirements of birds are unknown, however the natural raptor diet is always relatively high in protein and fat and low in carbohydrates. Whole prey diets have a calcium/phosphorus ratio of 1.5:1 as the bird actually consumes the bones as well as the meat…
Raptors are a diverse group of birds consisting of order Strigiformes or owls and diurnal birds of prey such as falcons, hawks, and eagles. Order Falconiformes, traditionally considered a broadly defined, polyphyletic group, has recently been divided into two orders with only family Falconidae (falcons and caracaras) remaining in Falconiformes. Other diurnal raptors belong to order Accipitriformes …

Twitter topics ranged from turtle and tortoise ophthalmic anatomy to chelonian clinical problems like blepharedema, commonly associated with hypovitaminosis A in aquatic turtles.
Calcium is the most abundant mineral in the body, and the majority of total body calcium is found within bones and teeth. Most mammals make only one or two sets of teeth in a lifetime, however rabbit teeth continually grow throughout their lifetime. This continual tooth eruption plays an important role in the rabbit’s long-term calcium needs.
Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs) that comprise a small percentage of dietary lipids ingested by humans and animals. The name “omega-3” refers to the location of the double bond closest to the methyl end of the hydrocarbon chain, and may be alternatively referred to as “n-3” in the literature. Chief among the omega-3 fatty acids is…
Fennec foxes (Vulpes zerda) are the smallest members of Order Carnivora. Females or “vixens” weigh approximately 0.8 kg. Adult males or “reynards” reach up to 1.5 kg and stand 18 -22 cm at the shoulder. Its most distinctive feature is characteristic large pinnae, which function to dissipate heat and enhance hearing. Fennec foxes are highly specialized to desert life and found almost exclusively in arid, sandy regions. Densest populations are found in the central Sahara desert region of North Africa.

A bird is a wing guided by an eye… Rochon-Duvigneaud: Lex Yeux et La Vision Des Vertebres
The avian eye is a large structure that takes up a significant portion of cranial mass. Raptors depend heavily on vision in order to compete successfully for survival. The posterior aspect of the eye fits snugly within the large bony orbit. The globes are separated by a thin interorbital septum, which measures significantly less than 1 mm in some areas…
The avian patient poses special challenges for delivery of injectable medications. Although the techniques involved are not unique to birds, special knowledge of avian anatomy as well as delicate, proficient technical skills are required. Depending on the species, the individual, and the clinical situation, injections can be delivered by intramuscular, intravenous, intraosseous, subcutaneous, intratracheal, or intracoelomic routes. Parenteral drug administration provides the advantage of delivering a precise dose when a rapid therapeutic response is necessary. Disadvantages include stress as well as the potential irritation or pathology that can occur at the injection site.
Diarrhea is a common clinical presentation in avian medicine. Diarrhea may be caused by a variety of conditions, however it is particularly important for the practitioner to understand the anatomy and diseases of the avian gastrointestinal tract and associated organs.
The most widespread mineral in the body, calcium is required for normal metabolism and bone mineralization.
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.

Herbivore nutrition separates animals into two main categories, depending on where food particles are broken down and fermented prior to absorption. The categories are foregut and hindgut fermenters, with the hindgut group being broken down into colonic and cecal fermenters.
Air sac cannulas are routinely used to ventilate birds by a route other than endotracheal intubation. Air sac tubes are used for oxygenation and anesthesia, especially during surgery of the head or trachea where tracheal intubation would be cumbersome. In addition, air sac cannulas provide a means to medicate air sacs directly, and they are also used to aid dyspneic birds with tracheosyringeal obstruction from foreign bodies, granulomas, or tumors.

The ferret is a carnivore with a short, simple gastrointestinal tract and a relatively rapid gastrointestinal transit time. Diarrhea is the most common clinical sign in ferrets with gastrointestinal disease, with the exception of gastrointestinal foreign bodies where anorexia and weight loss are the primary presenting complaints.
Primarily a disease of captive reptiles, dysecdysis is sporadically seen in free-ranging reptiles. Among captive reptiles, difficult sheds are most common in those with a complete shedding cycle: snakes and some geckos such as the leopard gecko and African fat-tailed gecko. Some skinks with relatively tiny digits, are prone to retaining shed skin on the digits.
External reproductive anatomy is obvious in some adult small mammals such as the ferret, sugar glider, hedgehog, rat, guinea pig, and hamster. Gender determination or sexing can be challenging in some species like the chinchilla, and in many neonatal rodents. In these cases, reliance on anogenital distance or the distance between the rectum and the urogenital region is considered best practice.
The average small animal veterinarian may easily become comfortable with ferrets. Ferrets are hardy and relatively stoic, and as members of the order Carnivora, ferrets are predator species that approach the world in a manner similar to cats and dogs. A relatively small number of medical problems are seen very commonly in ferrets. Careful study of these conditions and attention to the unique aspects of ferret anatomy and behavior will prepare the veterinarian for basic emergency care of the ferret.

Acquired dental disease is an important problem in pet rabbits and rodents. Clinical management of dental disease is complex, frequently involving invasive technical procedures, therefore it is preferable to promote dental health, rather than treating dental disease. What are five things you can do to promote dental health in small herbivores?
Most small herbivores like the rabbit, guinea pig, and chinchilla possess a simple, non-compartmentalized stomach paired with a large cecum and colon. To feed the small herbivore gastrointestinal tract, provide insoluble dietary fiber to stimulate gut motility and maintain gastrointestinal health. A balanced small herbivore diet contains adequate fiber (minimum 25%), minimal starch, and moderate protein levels. Among small herbivorous non-ruminants, the gastrointestinal tract of the rabbit is the most specialized and this manuscript will focus on unique features of this species’ anatomy and physiology.
