A rectilinear dependence of the flight velocity on the frequency of the wings flaps has been determined. Maximal, minimal and cruising velocities of flight of Phalacrocorax urile Gm are somewhat higher than those of Phalacrocorax pelagicus Pall and are 72.0; 40.0; 55.0 km/h and 70.0; 38.0; 53.0 km/h, respectively. Frequency of the wing flaps in both species is within 4-6 Hz. Load on wings is higher in Phalacrocorax urile Gm. (1.43 g/cm2) than in Phalacrocorax pelagicus Pall (1.31 g/cm2), its wings being less elongated. As to the reduced step magnitude these birds differ but slightly from each other. The obtained data are compared with those for birds from other orders with different degree of their adaptation to water medium.Методом киносъемки и собранного морфологического материала (по крыльям) получены и проанализированы кинематические параметры горизонтального полета в природных условиях при различных режимах и скоростях берингийского и краснолицего бакланов в связи с особенностями строения летных органов. Полученные данные сравниваются с таковыми у водоплавающих птиц из других отрядов с разной степенью адаптации к жизни в водной среде.ru
