A Cross‐Sectional Study on Parakeets Feeding and Housing Practices in Italy

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Italy has one of the largest companion bird populations in Europe. This study aimed to investigate feeding and housing practices among Italian parakeet owners. An online questionnaire was distributed, yielding 433 voluntary responses. Participants were classified as hobbyists (HBY; ≤ 13 birds owned) or breeders (BRD; > 13 birds owned) to ...

Balancing conflict and coexistence: Interactions between invasive monk parakeets and native urban birds

open access: yesEcological Applications, Volume 36, Issue 4, June 2026.
Abstract Biological invasions often generate complex ecological paradoxes, particularly when invasive species act as ecosystem engineers that simultaneously compete with and benefit native communities. Understanding these dual dynamics is critical for managing urban biodiversity.

Assessing the Genetic Health and Conservation Value of an Introduced Urban Population of a Critically Endangered Parrot

open access: yesEvolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Non‐native species can be introduced to novel environments such as cities via wildlife trade. These populations may have conservation value—particularly if they are of a species threatened in its native range. Genetic tools can help assess the fitness of introduced populations by indicating if they are (1) suffering the consequences typically ...

General practice veterinarians’ attitudes towards avian influenza: A COM‐B analysis of barriers to backyard poultry treatment

open access: yesVeterinary Record, Volume 198, Issue 6, Page e237-e247, 14/21 March 2026.
Abstract Background The recent expansion of highly pathogenic avian influenza (HPAI) H5N1 to non‐avian species in the United States has intensified public health‐related concerns. In Great Britain, low veterinarian confidence in seeing and treating birds creates potential barriers to HPAI diagnosis and reporting.

The Effects of Human Presence, Restraint, and Stressed Neighbors on Corticosterone Levels in Domesticated Budgerigars (Melopsittacus undulatus)

open access: yesZoo Biology, Volume 45, Issue 1, Page 37-45, January/February 2026.
Female budgerigars (Melopsittacus undulatus) did not significantly elevate their plasma corticosterone levels in response to human presence at the beginning of the experiment. However, plasma corticosterone was significantly elevated by restraint stress, the return of a neighbor that received restraint stress, and human presence at the end of the ...

Distinct 5′ UTR Requirements for Translation of the Bicistronic X/P mRNA Among Avian Orthobornaviruses

open access: yesMicrobiology and Immunology, Volume 70, Issue 2, Page 80-90, February 2026.
ABSTRACT Orthobornaviruses express X and the phosphoprotein (P) from a bicistronic X/P mRNA, and these proteins regulate polymerase activity. In mammalian orthobornaviruses, the 5′ untranslated region (5′ UTR) of the X/P mRNA controls the translational balance between X and P and thereby promotes efficient replication.
