Nuclear parcellation of pontine catecholaminergic and cholinergic neurons in gray parrots and pied crow brains

The Anatomical Record, Volume 308, Issue 9, Page 2433-2449, September 2025.
Immunohistochemical staining for tyrosine hydroxylase reveals the neurons forming the locus coeruleus complex in the pontine region of the brain of the Congo gray parrot. The appearance and parcellation of the locus coeruleus complex in birds shows many similarities, but also differences to that observed in mammals.

Multidrug‐Resistant Extended‐Spectrum Beta‐Lactamase (ESBL) Producing Escherichia coli in Pet Birds of Bangladesh

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
An alarming 43.83% of cloacal samples revealed multidrug‐resistant ESBL‐E. coli, with TEM being the most frequently detected resistance gene. These results underscore pet birds as hidden reservoirs of MDR pathogens, posing a potential threat to public health in Bangladesh. Routine surveillance and responsible antimicrobial use are crucial to mitigating

Lost companions: a new quill mite species and its possible coextinction with the Carolina parakeet

Parasitology
Investigations of the parasites associated with extinct avian species provide unique insights into the ecology and evolution of both hosts and their parasitic counterparts. In the present paper, a new quill mite species, Peristerophila conuropsis sp. n.,

Avian Lifespan Network Reveals Shared Mechanisms and New Key Players in Animal Longevity

Aging Cell, Volume 24, Issue 9, September 2025.
In this work, we found that birds with similar lifespans exhibit convergent evolution in specific genes, suggesting that shared evolutionary pressures shape the genetic basis of lifespan similarity across species. By investigating protein–protein interactions across genes evolving convergently in long‐ and short‐lived species, we identified a network ...
