From: On the role of tail in stability and energetic cost of bird flapping flight
Locus of the steady and level solutions in the gait parameter space. Coloured surfaces are representing slices of this locus, at every \(5^{\circ }\) of tail opening. (a) Cost of Transport. (b) Stability indicator captured via the largest Floquet multiplier. Unstable limit cycles are represented with different shades of yellow-to-red, and stables ones are in green; the transition appears around \(\beta = 25 ^{\circ }\) (Color figure online).
