Flexibility in the face of climate change? A rapid and dramatic shift toward later spring migration in Hudsonian Godwits (Limosa haemastica)

This study tracks shifts in Hudsonian godwit migration timing and finds a rapid 6-day delay with no sex differences, suggesting non-adaptive responses to climate change.

The architecture of phenotypic flexibility within a complex trait: an empirical case study using avian thermogenic performance

This study examines phenotypic flexibility in avian thermogenic performance by analyzing physiological traits and metabolic rates in Dark-eyed Juncos under temperature changes, finding non-symmorphotic responses.

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.

Body temperature maintenance acclimates in a winter-tenacious songbird

This study shows that Dark-eyed Juncos adjust both heat production and conservation mechanisms during cold acclimation to improve body temperature regulation over time.
