About the Cover
Cover:
Colour-coded distributions of the wake disturbance created by a thrush nightingale in slow (top panel) and fast (middle panel) flight in the Lund wind tunnel, as revealed by an accurate, custom digital particle imaging velocimetry method. The data come from vertical sections in the centre plane, and proposed three-dimensional reconstructions from assembling multiple slices at different positions across the wingspan are shown diagrammatically below. They include examples from slow (left), medium (middle) and fast (right) flight speeds. The wake structures are similar to, but not exactly the same as expected from existing flight models or previous experimental data. In particular, at most flight speeds the wake is some variation on the intermediate, medium-speed form. The details and consequences of these similarities and differences for aerodynamic modelling of bird flight are explored by Spedding, Rosén and Hedenström (pp. 2313-2344).
