Hot days are associated with short-term adrenocortical responses in a Southern African arid-zone passerine bird.

L. L. Moagi, A. R. Bourne, S. J. Cunningham, R. Jansen, C. A. Ngcamphalala, A. R. Ridley, A. E. McKechnie

This study links high daily temperatures to increased stress hormone levels in Southern pied babblers, indicating acute heat stress responses above 38°C.

Dehydration risk, not ambient incubation, limits nest attendance at high temperatures

A. R. Bourne, A. R. Ridley, A. E. Mckechnie, C. N. Spottiswoode, S. J. Cunningham

This study shows that high temperatures force pied babblers to leave nests to avoid dehydration, not because they benefit from ambient incubation.

Avian thermoregulation in the heat: is evaporative cooling more economical in nocturnal birds?

R. S. O'Connor, B. Smit, W. A. Talbot, A. R. Gerson, M. Brigham, B. O. Wolf, A. E. McKechnie

This study compares evaporative cooling efficiency between nocturnal and diurnal birds in hot environments, finding mixed results with some nocturnal species showing reduced water loss but others having higher cooling efficiency.

Avian thermoregulation in the heat: phylogenetic variation among avian orders in evaporative cooling capacity and heat tolerance

B. Smit, M. C. Whitfield, W. A. Talbot, A. R. Gerson, A. E. McKechnie, B. O. Wolf

The paper quantifies phylogenetic variation in avian evaporative cooling efficiency and heat tolerance among three bird orders, finding unexpected differences in physiological mechanisms.
