Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

BRIEF OBSERVATIONS ON THE SEMEN AND SPERMATOZOA OF CERTAIN PASSERINE AND NON-PASSERINE BIRDS [PDF]
Summary. The semen of some passerine and non-passerine birds was examined. That of passerine birds was thick in consistency and contained relatively few spermatozoa, while that of non-passerine species was more liquid in nature with many spermatozoa.

Data from: Earth history and the passerine superradiation
Avian diversification has been influenced by global climate change, plate tectonic movements, and mass extinction events. However, the impact of these factors on the diversification of the hyperdiverse perching birds (passerines) is unclear because ...

Land birds on atolls: diversity, origin, and function
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Host range expansions are an important factor for shaping the community of associated symbiotic organisms. Birds, as a highly mobile group of animals, are of particular interest to study with respect to the diversity and the distribution of the organisms

The Worm-eating Warbler (Helmitheros vermivorum) is typically described as a mature forest species requiring moderate to steep slopes and dense understory vegetation for breeding. However, nesting microhabitat characteristics vary regionally.

Passerine and Softbill Therapeutics
Passerines (songbirds) and softbills (toucans and mynahs) are increasingly presented for veterinary care as pet owners and aviculturists recognize that successful medical and surgical treatment can be performed in these often tiny patients. Even with an increasing amount of pharmacokinetic data in birds, the use of extrapolated drug regimens continues ...

Food‐solicitation displays in nestling birds: still begging for answers
ABSTRACT Nestling begging is a key model for understanding animal communication and parent–offspring conflict. Dynamic begging displays are often interpreted as costly, honest signals of need, with honesty maintained by viability costs, as proposed in Godfray's influential signalling model.

ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile
