Overview


Vance Tucker is interested in comparative physiology, particularly the energetics of locomotion, and the interactions between an organism's natural environment and its respiratory and circulatory systems. Much of his research has dealt with the aerodynamics and energetics of avian flight, and has also included work on mammals, reptiles, amphibians and insects. He is particularly interested in those aspects of physiology that can be described in physical or physical-chemical terms, usually involving math ematical models. Examples of such subjects are: energy storage by stretched elastic structures in running animals, wave making by insects swimming on water surfaces and heat exchange in animals entering into and arousing from hibernation.

The deep fovea, sideways vision and spiral flight paths in raptors.

Journal Article The Journal of experimental biology · December 2000 Raptors - falcons, hawks and eagles in this study - have two regions of the retina in each eye that are specialized for acute vision: the deep fovea and the shallow fovea. The line of sight of the deep fovea points forwards and approximately 45 degrees to ... Full text Cite

Curved flight paths and sideways vision in peregrine falcons (Falco peregrinus).

Journal Article The Journal of experimental biology · December 2000 When diving at prey straight ahead from great distances at high speeds, a peregrine has a conflict between vision and aerodynamics: it must turn its head approximately 40 degrees to one side to see the prey with maximum visual acuity at the deep fovea of o ...

Gliding flight: drag and torque of a hawk and a falcon with straight and turned heads, and a lower value for the parasite drag coefficient.

Journal Article The Journal of experimental biology · December 2000 Raptors - falcons, hawks and eagles in this study - such as peregrine falcons (Falco peregrinus) that attack distant prey from high-speed dives face a paradox. Anatomical and behavioral measurements show that raptors of many species must turn their heads a ... Full text Cite
