This chapter presents a study on the oxygen storage and blood transport as adaptations for flight in birds. In this study, three species of birds representing different levels of activity were analyzed: (1) the quail (Coturnix coturnix), (2) the starling (Sturmus vulgaris), and (3) the ...

in brain activity that characterize sleep are required to answer this question. Furthermore, such recordings are needed to establish the amount, intensity, and types of sleep, and the potential implications that flight-related sleep adaptations have for understanding the functions of sleep. Due to ...

The avian nature ofArchaeopteryx’s humeral and ulnar cross-sectional geometry shares more flight-related biomechanical and physiological adaptations with modern volant birds than previously known, which we argue to reflect the shared capability of powered flight.Confuciusornisfrom the Early Cretaceous of ...
Passeriform - Flight, Adaptations, Foraging: The single feature distinguishing passerines from all similar birds is their “perching” foot. A number of species are largely terrestrial and have feet modified for walking and running. The bills are extraor
