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.

This paper examines incubation behavior in two swallow species breeding in different climates, finding that ambient temperature, clutch size, and daylight duration shape distinct strategies to maintain consistent incubation.
