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.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)
Journal of Anatomy, Volume 249, Issue 4, Page 705-713, October 2026.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 ...

Mitigating Effects of Nest Structure on Predation Risk in Hainan Partridge (Arborophila ardens)
Ecology and Evolution, Volume 16, Issue 9, September 2026.Enclosed nest structures can disrupt predator search efficiency and reduce predation risk. Predation rate in the uncovered group was significantly higher than that in the covered group. Our study highlights the functional limitations of nest‐structure evolution within complex predation environments.

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

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 ...
