Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 4, Page 414-426, May 2026.ABSTRACT With climate change, birds will face increasing thermoregulatory demands, which may alter reproductive behaviors such as offspring provisioning. Experimental studies have shown that the provisioning capacity of female tree swallows (Tachycineta bicolor) is limited by their risk of overheating. Given that parental investment strategies may vary

Effect of forward velocity and crosswind on the reverse-thrust performance of a variable-pitch fan engine [PDF]
A full-size variable-pitch fan engine was tested in the Ames 40 by 80 foot wind tunnel to determine the effect of forward velocity and crosswind on reverse-thrust performance.

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.SUMMARY A 17‐year‐old, 24‐kg, female greater rhea (Rhea americana) presented with an acute onset of left wing droop. Clinical examination and radiographs revealed an open, simple, displaced, short‐oblique diaphyseal fracture of the distal third of the left humerus.

Chlamydia avium‐associated hepatitis in a fancy pigeon (Columba livia f. domestica)
Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.Abstract A 5‐year‐old, male, fancy pigeon (Columba livia f. domestica, 380 g), found dead without prior clinical signs, was submitted for diagnostic postmortem examination. Histologically, the animal exhibited heterophilic to mononuclear hepatitis consistent with avian chlamydiosis; however, Chlamydia psittaci‐specific real‐time polymerase chain ...

Integumentary fibrosarcoma in a free‐living swan (Cygnus olor): Medical and welfare considerations
Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.Abstract A 10‐kg adult male mute swan (Cygnus olor) of unknown age was admitted for investigations of two large ventral masses overlying the keel bone, which were discharging purulent material. The masses measured 8.9 × 2.1 cm and 4.2 × 3.2 cm. Empirical treatment with non‐steroidal anti‐inflammatory drugs and antimicrobials was instigated.
