This study examines geographical variation in plasma bactericidal ability (BKA) among tree swallow populations, finding lower BKA in northern populations and during incubation, suggesting trade-offs between reproduction and immunity.

This study examines how robustness and resilience to cold snaps affect tree swallow fitness using long-term behavioral data.

The paper shows that tree swallow populations have similar sensitivity to temperature but differ in vulnerability due to timing constraints and exposure to warming.
