Perching birds or songbirds belong to order Passeriformes, which makes up the largest taxonomic group of birds. Passeriforms make up nearly 60% of all birds with over 5,000 species belonging to this group. If you are comfortable with psittacine anatomy and physiology, then you are well on your way to understanding passerines. LafeberVet has listed ten interesting, clinically significant facts about passerine anatomy and physiology…
Avian veterinarian Brian Speer presented this live webinar, RACE-approved for 1.5 credit hours. Reproductive activities, particularly those that are recurrent, pose a significant threat to the health and behavioral well-being of many pet birds. This presentation began by reviewing the basics of female reproductive anatomy and endocrinology before discussing the role of environmental and behavioral stimuli on reproductive endocrinology. Dr. Speer then presented an ethical scale for selecting and prioritizing recommendations for intervention, before discussing medical therapy as well as the environmental and behavioral interventions that can be employed. Dr. Speer concluded with a discussion of behavioral science and its applications to the management of hormonal problems.
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.
Change in bird song or loss of voice can be valuable diagnostic clues. When a bird is presented for a change in or loss of voice, this will localize lesions to the…
“Normal Body Weights in Birds” is a collection of normal reported weights in common companion birds and birds of prey presented in table format. Keep in mind that reported normal body weights for a given species can vary significantly…
It is important for animal health care professionals to recognize the potential hazards of working with passerine birds so that appropriate measures can be taken to minimize the risk of contracting disease. Wild bird isolates of Salmonella enterica serotype typhimurium may not represent a large zoonotic risk to the general population, however the vast majority of sick and dying songbirds harbor this microbe.
Signs of avian polyomavirus type 1 in the budgerigar parakeet can be quite variable. Feather dystrophy or abnormal feather growth can lead to deformed flight feathers. Affected birds are unable to fly and are called “runners” or “creepers”. “French molt” is a term sometimes used for this slow, debilitating disease in parakeets characterized by progressive development of abnormal feathers. Bleeding is another hallmark of clinical avian polyomavirus infection…
Approach to the passerine bird relies on the same concepts of “One Medicine” used in all animals. Nevertheless many of the infectious agents diagnosed in songbirds are relatively unique to this taxonomic group, or at least much more prevalent when compared to psittacine birds or birds of prey.
When hospitalizing any wildlife patient, the goal should always be to transfer the animal to an experienced, licensed wildlife rehabilitator as soon as possible. In the meantime, it is imperative that the passerine bird be housed appropriately to promote recovery and prevent injury.
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.
This client education handout reviews some basic principles of reproductive behavior in the companion bird. When is puberty seen in popular pet birds? How do breeding pairs behave in the wild, and what does broody behavior look like in in the pet bird? What environmental cues promote avian reproductive behavior and what can be done to minimize reproductive behaviors in the pet bird?
Reproductive problems are a common problem in many small pet bird species, particularly cockatiels, budgerigars parakeets, lovebirds, finches, and canaries. Use client education handout to briefly explain egg laying problems, from egg binding and egg yolk peritonitis to chronic egg laying to the companion parrot owner.
Historically, routine Gram’s stains were performed in apparently healthy birds. As our understanding of avian medicine has grown, avian veterinarians have questioned the reliability and validity of Gram’s stain cytology as a screening test. Cytology is indicated when specific problems are reported during a detailed medical history or when…
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.
