This case report describes the clinical, parasitologic, pathologic, and histologic characteristics of a golden pheasant () with an infection of in Mississippi. An approximately 2-yr-old golden pheasant from a flock of 8 to 10 birds was submitted to the Poultry Research and Diagnostic Laboratory in Pearl, MS, for necropsy. Clinical history indicated that three flock mates had died of unknown causes in the past. At necropsy, the submitted pheasant showed severe nodular typhlitis associated with the presence of numerous whitish small nematodes inside the cecal walls and lumen with morphologic features consistent with . The histologic examination showed multifocal to coalescing, nodular, granulomatous, and lymphocytic typhlitis with fibroplasia, and multiple intralesional nematodes. Furthermore, the presence of similar nematodes in the lung indicated a possible aberrant migration of sp. to this organ. The flock was subsequently treated with an oxfendazole-containing dewormer and suffered no further losses.

Avian genomes exhibit compact organization and remarkable chromosomal stability. However, the extent and mechanisms by which structural variation in avian genomes differ from those in other vertebrate lineages are poorly explored. This study generated a diploid genome assembly for the golden pheasant ( ), a species distinguished by the vibrant plumage of males.

Background: The interaction between visitors and captive birds is complex, with a potential impact on bird's behavior and welfare. Understanding this interaction is essential for effective conservation and management.
Methods: We conducted a study at the University of Haripur's pheasantry in Khyber Pakhtunkhwa, Pakistan to investigate the effects of visitor numbers, duration of visitor presence, and climatic factors on the behavior of female pheasants.

The fecal microbiota plays an important role in maintaining animal health and is closely related to host life activities. In recent years, there have been an increasing number of studies on the fecal microbiota from birds. An exploration of the effects of species and living environments on the composition of gut microbiota will provide better protection for wildlife.

The gastrointestinal tract (GIT) of animals contains various helminth parasites, responsible for subclinical and clinical parasitism. The health situation of animals is seriously affected by these parasites and leads massive financial losses for the livestock trade. The present study was conducted to determine the prevalence and associated risk factors of GIT parasites in small and large ruminants of Mardan district and zoo animals of Golden Life Safari Park Khyber Pakhtunkhwa.

The role that visual discriminative ability plays among giant pandas in social communication and individual discrimination has received less attention than olfactory and auditory modalities. Here, we used an eye-tracker technology to investigate pupil fixation patterns for 8 captive male giant pandas . We paired images (26) of conspecifics against: 1) sympatric predators (gray wolves and tigers), and non-threatening sympatric species (golden pheasant, golden snub-nosed monkey, takin, and red panda), 2) conspecifics with atypical fur coloration (albino and brown), and 3) zookeepers/non-zookeepers wearing either work uniform or plain clothing.
