A mixed thymoma was diagnosed in a 15-year-old female American robin ( Turdus migratorius) that exhibited poor body condition, dysphagia, hyporexia, and depression. A 1.5-cm subcutaneous nodule was present in the cranio-ventral cervical region, which had been noticed by the owner 15 days before presentation. On cytologic evaluation of a fine-needle aspirate, well-differentiated lymphocytes were observed. Surgical excision was elected; however, the mass was firmly attached to the esophagus and the jugular vein, and the attempt at excision resulted in fatal hemorrhage...

Mycobacterium genavense is regarded as the primary cause of mycobacteriosis in passerine and psittacine birds kept in captivity. Mycobacterium genavense is a potential zoonotic pathogen; therefore, early antemortem detection in birds is needed. In humans, infections with M genavense are found predominantly in immunocompromised people. To investigate clinical signs and pathologic lesions and to determine the prevalence of coinfections in birds infected with M genavense, we reviewed records of 83 birds in which DNA from M genavense had been detected via real-time polymerase chain reaction...

Ownership of backyard chickens (BYCs) is increasing in urban areas, and BYCs often have access to soil around the home. Exposure to lead-contaminated soil is a known health risk for people; however, the degree to which BYCs are exposed is unknown. We employed a cross-sectional convenience sample to assess blood lead levels (BLLs) in 57 BYCs from 30 flocks in a region with established environmental lead contamination. Over two-thirds (70.2%) had detectable levels of lead in their blood, which averaged 12.5 μg/dL (range: <3...

Tibiotarsal fractures are a common presentation in small bird species and anecdotally have been reported to carry a good prognosis with proper treatment, such as external coaptation. For this retrospective study, the medical records of 5 institutions were reviewed for tibiotarsal fractures diagnosed in companion birds weighing less than 200 g. A total of 86 cases met the inclusion criteria. Cockatiels ( Nymphicus hollandicus) (24/86) and budgerigars ( Melopsittacus undulatus) (19/86) were the most frequently represented species...

Richard R Burdeaux, Laura Wade
An adult, male snowy owl ( Bubo scandiacus) was found down and unable to fly in western New York State. Physical examination and radiographs revealed a subacute, open wound and fractured major and minor metacarpals of the right wing. A minimal type II external skeletal fixator (ESF) device was placed on the right major metacarpal bone and the open wound was allowed to granulate and close. After evidence of bone union, the ESF device was removed. The owl performed auto-physiotherapy throughout the process and was released with sustained flight 2 months postoperatively...

To further knowledge of the physiology of opioid receptors in birds, the structure and expression of the μ-, δ-, and κ-opioid receptor genes were studied in a peregrine falcon ( Falco peregrinus), a snowy owl ( Bubo scandiacus), and a blue-fronted Amazon parrot ( Amazona aestiva). Tissue samples were obtained from birds that had been euthanatized for poor release prognosis or medical reasons. Samples were taken from the brain (telencephalon, thalamus, pituitary gland, cerebellum, pons, medulla oblongata, mesencephalon), the spinal cord and dorsal root ganglions, and plantar foot skin...

A 1.5-year-old Polish hen was presented with a history of watery droppings and poor vent tone. Results of diagnostic tests revealed blood lead at levels considered to be toxic. Chelation therapy was started with calcium ethylenediaminetetraacetate. The hen was laying eggs before, during, and after chelation therapy. Eggs were tested for the presence of lead by combining yolk and albumen together. Before chelation therapy, the level of lead in the egg tested was 14 μg. Two days after the end of chelation therapy, results of a second blood lead test revealed a drop to nontoxic levels...

An 8-year-old male yellow crowned Amazon parrot ( Amazona ochrocephala) was presented for an 8-month history of intermittent regurgitation, anorexia, and lethargy along with a 3-week history of a soft tissue mass cranial to the vent. Examination revealed a small soft tissue mass, approximately 2 cm in diameter, within the body wall of the coelomic cavity with no discoloration of the surrounding tissue. Full body computed tomography (CT) revealed a defect in the body wall on the ventral coelom from the right paramedian location extending to the right side, which contained intestines...

A 30-year-old bald eagle ( Haliaeetus leucocephalus) was presented with a history of hyporexia and lethargy. Results of initial hematologic testing, biochemical analysis, and fecal examination were unremarkable, and clinical signs did not resolve with supportive care and management changes. Results of echocardiography, based on auscultation of a murmur, and coelomic endoscopy, based on the presence of a soft tissue opacity on radiographs, as well as an aspergillosis panel were largely unsuccessful in determining a definitive diagnosis...

A 25-year-old female yellow-naped Amazon parrot ( Amazona auropalliata) was presented for an acute onset of lethargy, ptyalism, and regurgitation. Results of hematologic testing and plasma biochemical analysis revealed severe leukopenia and heteropenia with toxic heterophils and marked hyperamylasemia and hypoproteinemia, consistent with gastrointestinal dysfunction. Survey radiograph findings were suggestive of coelomic effusion. Results of a contrast-enhanced computed tomography (CT) scan revealed a tubular, irregularly marginated structure along the medial aspect of the duodenum, consistent with an inflamed pancreas...

International conferences on avian medicine and surgery aim to disseminate scientific and evidence-based information in the form of oral presentations and posters. Most manuscripts presented are printed in the conference proceedings as abstracts. Subsequent publication in a scientific peer-reviewed journal is the natural outcome of the research cycle, although studies have shown that the vast majority of conference abstracts are not published. The purpose of this study was to explore 1) the fate of abstracts presented in avian conferences (Association of Avian Veterinarians, European Association of Avian Veterinarians, International Conference on Avian Herpetological and Exotic Mammal Medicine) in the years 2011-2015, 2) assess the publication rate in peer-reviewed journals, 3) describe the time course of subsequent publication, and 4) identify factors associated with increased likelihood of publication...

Matthew E Kinney
To determine the effect of capture and restraint on hematologic, plasma biochemical, and venous blood gas values in Dalmatian pelicans ( Pelecanus crispus), blood samples were collected and temperature and heart rate were recorded in 13 pelicans (5 males and 8 females) immediately after capture from a large field exhibit. Repeat sampling was performed after transport, a mean of 74 minutes after initial evaluation. When compared with values at initial sampling to the time of capture, significant increases were documented in the heterophil : lymphocyte ratio (H : L), carbon dioxide (CO2 ), bicarbonate (HCO3 ), total carbon dioxide (Tco2 ), base excess (BE), and partial pressure of carbon dioxide (Pco2 ) values after 74 minutes...

An adult, wild-caught, female Florida scrub jay ( Aphelocoma coerulescens) was evaluated because of an observable mass on the ventral neck. Initial physical examination and diagnostic tests were performed, which revealed a subcutaneous mass. Surgical removal of the mass was attempted, but the bird died during surgery. Results of necropsy and histopathologic evaluation identified the mass as thymic lymphoma with proventricular metastasis. Immunohistochemical staining revealed strong cytoplasmic immunoreactivity for CD3 in the thymic mass and within the predominant lymphoid population in the serosal proventricular masses, which confirmed metastasis of T-cell lymphoma...

A three-dimensional (3D) prosthesis was designed and built for a red-lored Amazon parrot ( Amazona autumnalis) with a pre-existing amputation of the distal left leg at the tibiotarsal-tarsometatarsal joint and injuries to the right leg caused by cage companion aggression. The prosthesis consisted of a straight main imprint, with a round element at both ends to provide stability, and a bridge connecting this to a socket without a bottom where the stump could be accommodated and held securely with self-adhesive bandaging...

Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) that has been used orally and intramuscularly in numerous avian species, but not studied to date, in African penguins ( Spheniscus demersus). The study describes the pharmacokinetic parameters of meloxicam after oral and intramuscular administration to African penguins. Several pilot studies were conducted initially where meloxicam (1, 0.5, and 0.25 mg/kg) was given intramuscularly to 4 birds, and orally (1 mg/kg) to 2 birds. Based on pilot study results, one group of 8 penguins was given meloxicam 0...
