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

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.

Cell Biology International, Volume 49, Issue 12, Page 1730-1750, December 2025.ABSTRACT Cryopreservation, biobanking, and in vitro propagation of cells from endangered species represent key strategies for advancing biodiversity conservation. The Hyacinth Macaw (Anodorhynchus hyacinthinus), a flagship avian species of the Brazilian Pantanal, is among the critically vulnerable taxa that stand to benefit significantly from such ...

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 ...

Auditory same/different concept learning and generalization in black-capped chickadees (Poecile atricapillus) [PDF]
, 2012 concept learning was thought to be uniquely human, but has since been observed in many other species. Discriminating same from different is one abstract relation that has been studied frequently.

Past research and future directions in understanding how birds use their sense of smell
Ibis, Volume 167, Issue 4, Page 853-881, October 2025.Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...
