Thermal acclimation in a non-migratory songbird occurs via changes to thermogenic capacity, but not conductance

This study shows that cold-acclimated black-capped chickadees increase their thermogenic capacity through higher metabolic rates and lean mass but do not change their thermal conductance.

Geographic variability of hybridization between Red-breasted and Red-naped Sapsuckers

The paper examines hybridization dynamics between Red-breasted and Red-naped Sapsuckers across different geographic regions, finding variation in hybrid zone characteristics influenced by local environmental factors.

Haemosporidian infection does not alter aerobic performance in the Pink-sided Junco (Junco hyemalis mearnsi)

This study investigates the physiological effects of haemosporidian infection on Pink-sided Juncos and finds no correlation between infection and aerobic performance metrics.

Temperature heterogeneity correlates with intraspecific variation in physiological flexibility in a small endotherm

The paper examines how temperature variation in the environment correlates with physiological flexibility in Dark-eyed Juncos and their relatives, finding genetic and phenotypic variation linked to thermal heterogeneity.

Origin and cross-century dynamics of an avian hybrid zone

The paper analyzes the origin and temporal dynamics of an avian hybrid zone between tanagers in Colombia, finding it likely originated from secondary contact and shows recent shifts in position and width.
