Clinical approach to small psittacines and passerines

open access: yesIn Practice, Volume 48, Issue 4, Page 181-189, May 2026.
Background: The most commonly encountered small avian species in clinical practice are psittacines, such as budgerigars, cockatiels and lovebirds, and passerines, such as finches and canaries. These birds are increasingly presented for veterinary treatment, with owners expecting a high standard of care.

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 ...

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.

Optimal diet strategy of a large-bodied psittacine: food resource abundance and nutritional content enable facultative dietary specialization by the Military Macaw

open access: yesAvian Research, 2019
Background Dietary specialization should arise when there is a relatively high abundance of a particular resource, where animals may select food items to obtain an optimal diet that maximizes energy intake.

Age Difference, Not Food Scarcity or Sibling Interactions, May Drive Brood Reduction in Wild Scarlet Macaws in Southeastern Peru

open access: yesDiversity
Avian brood reduction was initially thought to be driven by insufficient food supply. Now it is more commonly considered a consequence of asynchronous hatching and resulting siblicide, direct filial infanticide (where parents kill specific chicks) or ...
