Hummingbird-plant interactions in Chile: An ecological review of the available evidence
Avian Research, 2022 Hummingbird species have closely evolved with the plants they feed on, which is confirmed by their often tight ecological relationships in natural settings. Hummingbird-plant interactions are of interest for research areas such as ecology, evolution, and

Take-off mechanics in hummingbirds (Trochilidae) [PDF]
Journal of Experimental Biology, 2004 SUMMARYInitiating flight is challenging, and considerable effort has focused on understanding the energetics and aerodynamics of take-off for both machines and animals. For animal flight, the available evidence suggests that birds maximize their initial flight velocity using leg thrust rather than wing flapping.
