Sex and Age Effects on Monk Parakeet Home-Range Variation in the Urban Habitat

Diversity, 2021
Home-range size is a key aspect of space-use, and variation in home-range size and structure may have profound consequences for the potential impact of damage and control strategies for invasive species.

Fine‐scale genetic structure in co‐operatively breeding Palmchats (Dulus dominicus) suggests mixed kinship in compound nests

Ibis, EarlyView.
Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

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

Journal 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 ...

Cadaveric Study of the Juvenile Grey Heron's (Ardea cinerea) Nasal Cavity and Associated Structures Through Computed Tomography and Anatomical Sections

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study provides the first comprehensive anatomical and CT characterization of the nasal cavity of the grey heron, enabling the identification of its major components and spatial organization. Correlative evaluation of multiplanar CT images with anatomical sections proved highly effective for delineating landmarks, offering a reference for clinical ...

A Multispecies Systematic and Critical Review of Intranasal Administration in Veterinary Anaesthesia and Emergency Care: Promising Evidence and Overlooked Challenges

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This review evaluates the clinical potential and limitations of intranasal (IN) drug administration in veterinary anaesthesia and emergency care. IN delivery can provide clinically relevant sedation, analgesia and drug reversal, but its success is not universally reliable and is strongly influenced by species‐specific anatomy, formulation ...

Snowmelt predicts earlier breeding across the latitudinal range of an Arctic nesting seabird, the Little Auk (Alle alle)

Journal of Animal Ecology, Volume 95, Issue 7, Page 1248-1259, July 2026.
Multi‐year monitoring of the crevice‐nesting High Arctic seabird, the Little Auk (Alle alle), across four colonies spanning distinct climatic regimes revealed that snowmelt timing is a key and consistent driver of breeding phenology. Earlier snowmelt advances access to nesting habitat, enabling birds to initiate reproduction sooner. These findings show

Exploitation of Erythrina dominguezii Hassl. (Fabaceae)nectar by perching birds in a dry forest in western Brazil

Brazilian Journal of Biology
Among the vertebrate pollinated plants, the genus Erythrina includes tree species in which birds are the pollen vectors. Two groups in this genus may be distinguished: a) the hummingbird, and b) the perching bird pollinated species. Erythrina dominguezii
