Field Flight Dynamics of Hummingbirds during Territory Encroachment and Defense.
PLoS ONE, 2015 Hummingbirds are known to defend food resources such as nectar sources from encroachment by competitors (including conspecifics). These competitive intraspecific interactions provide an opportunity to quantify the biomechanics of hummingbird flight ...

Blue-Throated Hummingbird Song: A Pinnacle of Nonoscine Vocalizations
, 2000 Little is known about the structure and function of hummingbird vocalizations. We studied the vocalizations of Blue-throated Hummingbirds (Lampornis clemenciae) at two sites in southeastern Arizona. Songs were produced by males and females.

Vocalizations distinguish the cryptic giant hummingbird species and clarify range limits
Journal of Field OrnithologyVocal traits are often essential for distinguishing phenotypically cryptic taxa. The hummingbird genus Patagona comprises two species that differ in important aspects of their ecology and physiology but that are near identical in plumage and morphology:
