- W1998281773 abstract "Waterbirds are buoyant because of volumes of air in their plumage and respiratory tract. When they are submerged, their buoyancy is reduced, owing to compression of these volumes of air with depth. We tested how the horizontal submerged swimming of cormorants (Phalacrocorax carbo sinensis (Blumelbach, 1798)) changed when their buoyancy was artificially reduced. Birds were filmed swimming under water once with lead weights (density 11 000 kg·m –3 ) and again with dummy weights (density 1100 kg·m –3 ) attached to their body. The dummy weights had negligible weight under water and served as control for the increased drag in the experiment. Cormorants swimming with weights tilted their bodies at an angle of 3°–7° below the swimming direction, whereas the body of birds in the control groups was tilted at 14°–16°. The tilt of the body affected the orientation and trajectory of the tail and feet during swimming. A hydrodynamic analysis showed that the lesser tilt of the body (while swimming with weights equivalent to 26% of body weight) resulted in a 55%–57% reduction of the vertical hydrodynamic forces (lift, drag, and thrust) generated by the birds to overcome buoyancy. When more weights were added and the birds became negatively buoyant, these vertical forces changed direction to prevent sinking. Thus, by adjusting the tilt of the body, the birds may dynamically control their buoyancy to maintain straight horizontal swimming despite changes in buoyancy." @default.
