Ecological drivers and evolutionary consequences of torpor in Andean hummingbirds
D. C. R. Hernandez, J. Baldwin, G. A. Londono
This study examines torpor usage in Andean hummingbirds across an elevation gradient, finding that smaller birds use torpor more frequently at lower temperatures and that phylogenetic variation influences torpor use in harsh climates.
