Geographical variation in plasma bactericidal ability of breeding tree swallows (Tachycineta bicolor)

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.

Developmental cold exposure increases the ability to maintain body temperature during future cold challenges in a free-living altricial bird

This study shows that developmental cold exposure improves thermoregulatory capacity in tree swallows during future cold challenges.

Organismal robustness and resilience influence the ability to cope with cold snaps

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

Divergent climate impacts despite similar response to temperature in a widespread aerial insectivore

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

Ambient temperature, clutch size, and daylight are the main drivers of incubation behavior in two neotropical swallows breeding 8,000 km apart

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.
