Somatotroph Pituitary Tumors in Budgerigars ( Melopsittacus undulatus ) [PDF]
Veterinary Pathology, 2011 A series of 11 pituitary tumors in budgerigars were classified on the basis of their clinical, gross, microscopic, and immunohistochemical characteristics. Affected birds were young to middle-aged. Clinically, neurologic signs—including difficulties flying, ataxia, and blindness—were most commonly reported.

Journal of Anatomy, Volume 248, Issue 1, Page 82-93, January 2026.The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

Papovavirus‐like infection in budgerigars (Melopsittacus Undulatus) [PDF]
Avian Pathology, 1987 Outbreaks of a disease in two budgerigar aviaries caused 20% and 53% mortality respectively in recently hatched chicks during the 1985 breeding season. Clinical signs were first observed at 5 to 7 days of age. In most birds darkening of the normal skin colour was followed by death in 2 to 10 days.

Endogenous Amino Acids in Budgerigars(Melopsittacus undulatus).
Experimental Animals, 1998 To determine the amount of endogenous amino acids in budgerigars (sekiseiinko, Melopsittacus undulatus), as the first step of evaluating amino acid requirements, three experiments were conducted. In Experiments 1 and 2, transit time of the feeds through the digestive tract in budgerigars was studied.

How Do Oriental Reed Warblers Recognize Cuckoo Eggs?
Ecology and Evolution, Volume 15, Issue 12, December 2025.The cognitive basis and underlying mechanisms of the host egg rejection behavior remain not well understood. Egg recognition experiments using three egg mimicry levels (non, poorly, and highly mimetic eggs) to observe Oriental reed warbler (Acrocephalus orientalis) behavior at three breeding stages (pre‐egg‐laying, single host egg, and multiple host ...

Integrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...
