... A female American kestrel (Falco spaverius) fledgling was found on the ground with a suspected trauma to the right eye and open-mouth breathing. During the first 2 days of hospitalization, the bird developed severe bilateral periorbital cellulitis, blepharoedema, and sinusitis. The periocular tissues of the right globe were devitalized and communicated with a fistula at the commissure of the right ...
... A 1-year-old red-crowned parakeet (Cyanoramphus novaezelandiae) was presented with an acute onset of hyperprotraction of the upper beak and an inability to return the beak to its normal position. With the abnormal beak position, the bird was unable to eat. Standard radiographic images of the head supported a diagnosis of a rostroparasphenopalatal luxation. The luxation was reduced with a 23-gauge ...
... The red-crowned crane (Grus japonensis) is a critically endangered species. Three-dimensional–printed prosthetic beaks made of titanium alloy and polyether ether ketone (PEEK) were used to repair the beak of a red-crowned crane that had a complete fracture of the anterior maxillary bone and rhinotheca. The physical properties and stability of the prostheses and changes in the crane's behaviors aft ...

Abstract:
... Cryptococcus gattii infection in mammals and birds has been confined historically to tropical and subtropical regions in Australia, Southeast Asia, Africa, and South America. Since the early 2000s, numerous reports describe the emergence of C. gattii on the Pacific Coast of North America. We report on a C. gattii infection in an 8-year-old male citron-crested cockatoo (Cacatua sulphurea citrinocri ...
... Squamous cell carcinoma has been reported in a variety of bird species, most commonly psittacine and gallinaceous birds. The long-term prognosis in nongallinaceous birds is generally poor if complete surgical excision is not possible. Squamous cell carcinoma of the rhinotheca was diagnosed in a 34-year-old timneh African grey parrot (Psittacus timneh) with a 2-year history of beak abnormalities. N ...
... An adult female Chinese goose (Anser cygnoides) presented with a ventral displacement of the hyoid apparatus, associated with distension of the intermandibular sublingual space and of the gular skin, causing difficulties with prehension and deglutition of food and water. Physical examination revealed that the tongue was able to move normally and could be replaced into a normal anatomical position ...
... The red-tailed Amazon parrot (Amazona brasiliensis) is an endangered psittacine species, but little information is available about abnormal clinical findings and hematologic and biochemical values of this species, which are important for monitoring the health of this population. To determine hematologic and biochemical values for wild red-tailed parrot nestlings exhibiting abnormal clinical findin ...
... A 10-year-old, female umbrella cockatoo (Cacatua alba) was presented for evaluation of a mass at the right commissure of the beak, with associated right periorbital swelling. A feather cyst was suspected, based on history and the results of a computed tomography scan and fine-needle aspirate. The cyst was surgically debrided and removed. Histopathologic results confirmed an infraorbital keratin cy ...
... The effects of an injectable anesthesia with 0.05 mg/kg medetomidine, 5 mg/kg ketamine, and 0.5 mg/kg butorphanol administered together intramuscularly were evaluated in 22 captive Humboldt penguins (Spheniscus humboldti, 10 male and 12 female), with a mean age of 8.5 ± 8.23 years. The birds fasted for18–24 hours prior to the procedure. Induction was followed by 4 distinct progressive responses of ...
... Avian polyomavirus disease and psittacine beak and feather disease (PBFD) are both contagious viral diseases in psittacine birds with similar clinical manifestations and characterized by abnormal feathers. To determine the prevalence of Aves polyomavirus 1 (APyV) and beak and feather disease virus (BFDV) in captive, exotic psittacine birds in Chile, feathers from 250 psittacine birds, representing ...
... A 3-year-old female Bruce's green pigeon (Treron waalia) was presented with granulomatous inflammation of the cere and underlying tissues with osteomyelitis and bone proliferation of the dorsal premaxilla. Biopsy and culture revealed the presence of Mycobacterium avium-intracellulare complex, and multi-antimicrobial treatment was initiated with clarithromycin, ethambutol, rifabutin, and enrofloxac ...
... Beak and feather disease virus (BFDV), a circovirus, is the etiologic agent of psittacine beak and feather disease (PBFD), a progressive and often fatal disease in Psittaciformes. Even though neotropical psittacine species are more resistant to clinical infection than Old World species, BFDV is recognized as a threat to immunologically naïve wild psittacine flocks and its epidemiologic control is ...

Abstract:
... Lateral deviation of the upper beak (“scissor beak” or “wry beak”) is a common malocclusion in many species of birds but appears to be a common presentation in macaws (Ara species). This article describes transsinus pinning, a procedure in which a pin is passed through the frontal sinuses, turned parallel to the upper beak, and attached to the tip of the beak with an orthodontic rubber band to pro ...
