Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

Journal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Graded Levels of Dietary Valine in Protein‐Restricted Diets: Effects on Reproductive Performance and Tissue Morphology in Laying Japanese Quail

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Dietary supplementation of 0.95% valine in protein‐restricted diets optimizes reproductive performance, egg quality, and ovarian follicular development in laying Japanese quail. Higher levels do not provide additional benefits and may increase hepatic metabolic demand, highlighting the importance of precise amino acid formulation in low‐protein feeding

Prolactin and Triiodothyronine Modulate Seasonal Variation in Brown Adipose Tissue in Djungarian Hamsters

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 710-718, August 2026.
ABSTRACT Seasonal photoperiodic cycles regulate energy rheostasis in many animals. Brown adipose tissue (BAT) and the liver are key metabolic organs that show remarkable plasticity in response to photoperiodic conditions. Prolactin (PRL) and thyroid hormones are endocrine signals that transmit neural‐derived photoperiodic time measurement encoding to ...

Providing regular and frequent maps of losses and gains of farmland birds based on European monitoring data

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Evidence of Small Changes in Daytime Body Temperature in Active Black‐Capped Chickadees in Response to Supplemental Food Availability

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We experimentally manipulated the presence of supplemental food at a bird feeder and monitored subcutaneous temperature (Tsub) in 15 overwintering black‐capped chickadees (Poecile atricapillus) during feeder visits to investigate whether food availability shapes daytime Tsub.
