Abstract: Part 1 presents a comprehensive overview of the differences between mammals on s ling methods, processing, testing, and interpretation of data, with special attention to the meaning of pathologic and normal, and the differences among species and diseases. Part 2 critically analyzes 150 different hematologic and biochemical profiles obtained over 5 years from 150 psittacine birds belonging to 29 different species, brought to our clinic and/or examined in other locations, with confirmed or strongly suspected diseases. The results are grouped according to the various pathologies observed with respect to species and the degree of variation from the reference range of each species.

Abstract: A variety of infectious and noninfectious causes may contribute to feather-damaging behavior (FDB) in birds. This paper describes an episode of FDB behavior related to an isosexual group composition in a group of 20 golden conures (Guaruba guarouba) kept in a collective aviary. After ruling out infectious causative agents and analyzing the social bird group composition over a period of 10 yr, the male to female ratio of the group was reduced from 1.7 to 1.0. This intervention resulted in a significant improvement of the feather condition and improved reproduction. Further analysis revealed that FDB was not correlated to age, gender, or origin. In addition, FDB was associated with stress, as reflected by an elevated heterophil : lymphocyte ratio that decreased significantly following social restructuring. This study stresses the importance of an appropriate male to female ratio when golden conures are kept in aviaries.

Abstract: Disorders of the reproductive system represent a large portion of both large and small domestic animal medicine. Although some disorders of this system have been extensively studied in birds, this science is still in its infancy, when compared to mammalian reproductive medicine. This may be due to several reasons, but the simple fact that birds are oviparous renders knowledge of mammalian reproductive anatomy, histology, physiology, and disease process, inapplicable to avian patients. Nevertheless, several specific diseases or conditions affecting the reproductive system of birds have been described. By integrating information about the comparative anatomy and physiology of birds, reports of the most common reproductive diseases of birds and utilizing the latest diagnostic techniques, especially videoendoscopy, the avian practitioner should be able to diagnose and properly treat a high percentage of the avian reproductive diseases.

Abstract: There are few published studies regarding lesser flamingo (Phoeniconaias minor) reproduction, crop milk composition, and hand-rearing under human care. Between the end of June and the beginning of August of 2017, three eggs were laid in a group of 29 lesser flamingos kept under human care. Two eggs and one chick were abandoned by the parents, and three chicks were hand-reared. This report describes diet composition, dietary intake, feeding protocols, and growth index, from the first day to 60 days after hatching, for three lesser flamingo chicks.

Abstract: Usutu virus (USUV) infection was diagnosed in two free-living blackbirds and in three captive owls belonging to two different species in northern Italy in the summers of 2006-2008. Diagnosis was established by immunohistochemistry and RT-PCR. RT-PCR was performed on frozen and on paraffin-embedded tissues (PET), respectively. From the frozen s les a partial sequence of the putative USUV E and NS1 proteins (1229 bp) was determined, whereas partial sequences of the putative NS3 (278 bp) and NS5 (159 bp) proteins were obtained from PET. Additionally, one partial sequence (163 bp) of the putative 3'UTR region was determined from all s les. Sequencing of the lification products revealed 99.8-100% nucleotide identity of the Italian USUV strains to those from other central European countries.

Abstract: Several fungi species are reported to act as opportunistic agents of infection in avian species. After the isolation of Exophiala spp., a dematiaceous fungal pathogen associated with a mucosal lesion in a military macaw (Ara militar), s les were collected from another 24 birds of the order Psittaciformes to study the possibility of Exophiala spp. being part of the commensal microbiota of these animals or its possible association with other clinical conditions. Swab s les were collected from the trachea and/or choanae of the birds and inoculated in Sabouraud chlor henicol agar for fungal isolation. After incubation, fungal species were identified through their macroscopic and microscopic morphology. The presence of Exophiala spp. was identified in 15 of the 25 birds s led and no statistical association was found between the clinical record of the birds and the fungal isolation. Our results suggest that Exophiala spp. can colonize the upper respiratory airways of psittaciform birds and has a low pathogenic potential in these animals. To the authors’ knowledge, this is the first report of Exophiala spp. isolation from s les of the upper respiratory tract of Psittaciformes.

Abstract: Background: Part of the diagnostic workup for cardiac diseases is radiographic imaging. To determine an enlarged heart, species-specific reference values are necessary. Wild birds are rarely diagnosed with cardiac disease, and only a few studies have been done to investigate the cardiac silhouette in wild birds. Methods: In this retrospective study, the cardiac silhouette of 36 wild galahs, presented at the hospital, was investigated in relation to other anatomic landmarks like the thoracic width, clavicula width, synsacrum width, distance between the third and fourth rib, distance of the clavicula, and length and height of the sternum using a digital DICOM viewer. Results: The cardiac width was significant compared to the thoracic width with a minimum to maximum of 50 to 65%. The cardiac width compared with the coracoid width also showed significant results with a minimum to maximum range of 570 to 743%. A significant correlation was found between the weight and the cardiac width and length. Conclusion: The cardiac silhouette in wild galahs is easily measured in both radiographic views, and the heart size can be compared to other anatomical landmarks.
