Hummingbird torpor recapitulates key molecular signatures of hibernation without large-scale transcriptomic remodelling

Harsha Kumar, Emily R Blackwell, Donald R. Powers, Anusha Shankar

This study identifies key molecular pathways in hummingbird torpor entry through transcriptomic analysis, revealing subtle transcriptomic changes and active transcriptional reprogramming.

Tail Flaring During Agonism in Hummingbirds

Rosalee Elting, Md Zafar Anwar, Donald R. Powers…·Bret W. Tobalske

The paper examines tail flaring in hummingbirds during male-male fights, finding greater tail flare angles during fights compared to non-aggressive maneuvers and field observations show tail flaring is common in contests.
