Fig. 5. (A) Effect of prey size and phase (strike or transport) on the rhynchokinesis protraction angle (mean ± s.e.m.). Values with different letters are significantly different (Tukey's test). (B) Relationship between bill gape (mean ± s.e.m.) and rhynchokinesis protraction angle. Filled circles represent prey strike and open squares represent prey transport.
