The Nutrition of the Budgerigar (Melopsittacus undulatus)
Journal of Nutrition, 1991Growing interest in the nutrition of the budgerigar (Melopsittacus undulatus) has highlighted the paucity of knowledge in this area. The aims of this study were to review the available literature on their individual nutrient requirements and relate this to the nutrient content of their predominantly seed-based diet and to investigate the effect of the ...

A Pathogenic Paramyxovirus from a Budgerigar (Melopsittacus undulatus)
Avian Diseases, 1974 An outbreak of acute enteritis with high mortality among caged budgerigars (Melopsittacus undulatus) in a bird sanctuary was investigated. An agent with the properties of a paramyxovirus, but distinct from Newcastle disease virus and myxovirus Yucaipa, was isolated from one budgerigar. Inoculation of the virus intranasally, orally or intra abdominally,

Leiomyosarcoma in a Budgerigar (Melopsittacus undulatus)
Avian Diseases, 1988A tumor mass defined as a leiomyosarcoma was found in the thoracic cavity of a 3-year-old female budgerigar. Disseminated leiomyosarcomas were found in various body tissues, including bone marrow, spleen, and liver.

EXPERIMENTAL TOXOPLASMOSIS IN BUDGERIGARS (MELOPSITTACUS UNDULATUS)
Journal of Parasitology, 2002The susceptibility of budgerigars (Melopsittacus undulatus) to graded doses of Toxoplasma gondii oocysts was studied. Sixteen budgerigars were divided into 4 groups (A-D) of 4 each. Birds in groups A-C were fed 100,000, 1,000, or 100 infective oocysts of the VEG strain of T. gondii, respectively.

Malignant Melanoma in a Budgerigar (Melopsittacus undulatus)
Avian Diseases, 1991A 3-year-old male budgerigar was presented for weakness. A 0.5-cm mass was located in the left patagium. Histologically, the mass was diagnosed as a malignant melanoma, previously unreported in budgerigars.

Personality types in Budgerigars, Melopsittacus undulatus
Behavioural Processes, 2017The current study further characterized personality types in Budgerigars, an avian model that only recently demonstrated individual consistencies in behavior (Callicrate et al., 2011). Several methodological techniques, commonly used in previous examinations of other animal models, were employed.

Chronic Rhinitis and Sinusitis in Budgerigars (Melopsittacus Undulatus)
Avian Diseases, 1987The microscopic lesions in the nasal cavity, nasal bones, and infraorbital sinuses of five budgerigars with chronic upper respiratory tract infection are described. All five had chronic inflammation of the lining of the air spaces within the bones surrounding the nares and infraorbital sinuses.

Auditory pattern discrimination in budgerigars (Melopsittacus undulatus)
Behavioural Processes, 2022Auditory patterns carry information in human speech at multiple levels, including the surface relationships between sounds within words in phonology and the abstract structures of syntax. The sequences of other animal vocalizations, such as birdsong, can also be described as auditory patterns, but few studies have probed how the sequences are perceived
