This study measures body temperature repeatability and its association with metabolic performance in zebra finches, finding higher body temperatures correlate with better cold tolerance and exercise-induced hyperthermia.

This study shows that air temperature limits aerobic capacity and scope in active birds by causing overheating and reducing metabolic rate at higher temperatures.

This study tests the hypothesis that heat tolerance in birds is linked to body size through allometric relationships using Japanese quail breeds with extreme size variation, finding weak correlations and suggesting thermoregulatory benefits are not the primary driver of size changes.

The paper investigates how host age, sex, and location affect avian malaria prevalence in blue tits over time, finding age-related accumulation of infections and sex-specific differences in Leucocytozoon prevalence.

The paper shows that environmental effects, not selection or genetic drift, are driving declines in avian body size, with distributions narrowing and losing their upper tails.

This study examines how postnatal developmental temperature affects heat and cold tolerance in Japanese quail, finding that heatwave-like conditions increase heat tolerance while cold snap-like conditions improve cold tolerance, with no trade-off and reversible plasticity.

The study shows climate warming has increased malaria parasite prevalence and transmission in blue tits over 26 years, with specific temperature windows driving the trend.

This study shows that developmental cold exposure in Japanese quail increases mitochondrial susceptibility to heat stress, with effects reversible after acclimation to moderate temperatures.

This study investigates the ontogeny of endothermy in nestling blue tits, finding no effect of brood size on heat production development but highlighting early metabolic capabilities.

This study examines seasonal and environmental factors influencing gut microbiome variation in wild great tits across their range, finding higher diversity in winter and some habitat-related differences.

The paper shows that shrinking and shape-shifting in birds do not provide thermoregulatory benefits in a warming world, using experimental data on Japanese quail.
